Time-Limited Eating and Continuous Glucose Monitoring in Adolescents with Obesity: A Pilot Study

Due to its simplicity, time-limited eating (TLE) may represent a more feasible approach for treating adolescents with obesity compared to other caloric restriction regimens. This pilot study examines the feasibility and safety of TLE combined with continuous glucose monitoring (CGM) in adolescents. Fifty adolescents with BMI ≥95th percentile were recruited to complete a 12-week study. All received standard nutritional counseling, wore a CGM daily, and were randomized to: (1) Prolonged eating window: 12 h eating/12 h fasting + blinded CGM; (2) TLE (8 h eating/16 h fasting, 5 days per week) + blinded CGM; (3) TLE + real-time CGM feedback. Recruitment, retention, and adherence were recorded as indicators of feasibility. Weight loss, dietary intake, physical activity, eating behaviors, and quality of life over the course of the intervention were explored as secondary outcomes. Forty-five participants completed the study (16.4 ± 1.3 years, 64% female, 49% Hispanic, 75% public insurance). There was high adherence to prescribed eating windows (TLE 5.2 d/wk [SD 1.1]; control 6.1 d/wk [SD 1.4]) and daily CGM wear (5.85 d/wk [SD 4.8]). Most of the adolescents (90%) assigned to TLE reported that limiting their eating window and wearing a CGM was feasible without negative impact on daily functioning or adverse events. There were no between-group difference in terms of weight loss, energy intake, quality of life, physical activity, or eating behaviors. TLE combined with CGM appears feasible and safe among adolescents with obesity. Further investigation in larger samples, with a longer intervention duration and follow-up assessments are needed.     

Eating Earlier and More Frequently Is Associated With Better Diet Quality in Female Brazilian Breast Cancer Survivors Using Tamoxifen

BackgroundEmerging literature demonstrates that eating time and frequency are associated with quality and quantity of food consumption and anthropometric measurements. Considering that unhealthy dietary choices and obesity are important modifiable risk factors for breast cancer incidence and recurrence, this subject is relevant and has not been studied sufficiently in breast cancer survivors.ObjectiveThis study’s aim was to examine the association of eating time and frequency with diet quality, quantity of food consumption, anthropometric measurements, and body composition parameters in female breast cancer survivors using tamoxifen.DesignThis was a cross-sectional study.Participants/settingThis study was conducted from March 2015 to March 2016 at a Brazilian university hospital (Clinic’s Hospital, Federal University of Uberlandia, Uberlandia, Minas Gerais, Brazil) and included an assessment of 84 female breast cancer survivors using tamoxifen (mean [SD] age was 53.1 [8.7] years).Main outcome measuresQuantitative dietary assessment consisted of three 24-hour dietary recalls. The Brazilian Healthy Eating Index Revised was used for the qualitative diet analysis. Participants were classified by median eating time (early or late eaters of breakfast, lunch, and dinner), as well as by considering the middle time point between the first and last meal of the day (early or late midpoint eaters). Participants were also classified by median eating frequency (<5 or ≥5 eating episodes per day). Anthropometric measurements and body fat percentage by bioelectrical impedance were obtained.Statistical analysisGeneralized linear models and generalized mixed models were used to assess the associations between variables.ResultsEarly breakfast and dinner eating and early midpoint eating were associated with better scores for specific Brazilian Healthy Eating Index Revised components (P < .05). Early breakfast and dinner eating were also associated with better scores for the total index (P = .035 and P = .017, respectively). Early dinner eaters and early midpoint eaters had significantly lower daily energy consumption (P = .007 and P = .002, respectively). Eating ≥5 episodes per day was also associated with better scores of specific Brazilian Healthy Eating Index Revised components and the total index (P < .05). No significant associations between eating time and frequency with anthropometric measurements and body composition parameters were found (P > .05). However, women in the healthy body mass index category vs women in the overweight/obesity category had higher energy consumption at breakfast (P = .046).ConclusionsEarlier food intake time was associated with better diet quality and lower daily energy consumption. Higher frequency of eating was also associated with better diet quality. Future studies, such as randomized controlled trials, are needed to evaluate interventions addressing the timing and frequency of meals and their effect on diet quality and quantity in breast cancer survivors.     

Eating in the Absence of Hunger Is Related to Worse Diet Quality throughout Pregnancy

BackgroundScant research has examined whether laboratory assessments of eating in the absence of hunger (EAH) relates to long-term diet quality.ObjectiveThis study investigates the association of EAH with diet quality during pregnancy.DesignPregnancy diet quality was assessed using 24-hour diet recalls collected in each pregnancy trimester. EAH was assessed in a counterbalanced, crossover laboratory feeding substudy in which participants completed two free access eating occasions following a standardized meal during their second pregnancy trimester.Participants/settingData were collected from March 2015 to December 2016 from a subsample of participants (n = 46) enrolled at ≤12 weeks’ gestation in an observational, prospective cohort study (the Pregnancy Eating Attributes Study) in North Carolina.InterventionParticipants were presented with highly processed (HP) and minimally processed (MP) foods in two separate assessments.Main outcome measuresScores for total Healthy Eating Index-2015 (HEI-2015) and adherence to adequacy and moderation components were calculated from the diet recalls. Higher scores reflect better diet quality.Statistical analyses performedLinear regressions estimated associations of pregnancy diet quality with EAH (energy, EAH-kcal; and percent offered, EAH-%) in each condition for all foods, and separately for sweet and savory foods.ResultsLower pregnancy diet quality (all indicators) was associated with greater EAH (EAH-kcal and EAH-%) of all foods and sweet foods in the HP condition. Each 100-kcal increase in EAH of HP foods was associated with a 2- to 3-point decrease (standard error = 0.7 to 0.8) in HEI-2015 (P < 0.01); each 10% increase in EAH of HP foods was associated with a 5- to 7-point decrease (standard error = 2.0) in HEI-2015 (P < 0.01). Greater EAH (energy and percent offered) of savory food intake in the HP condition was associated with a lower HEI-2015 adequacy component score, but was not associated with the HEI-2015 or HEI-2015 moderation component scores. EAH in the MP condition was not associated with pregnancy diet quality.ConclusionsGreater EAH of HP, especially sweet, foods was related to worse pregnancy diet quality. Consuming HP sweets after meal termination may reflect a tendency for eating beyond satiation and may be a useful intervention target for improving maternal diet quality.     

Effects of an Evidence-Informed Healthy Eating Blog on Dietary Intakes and Food-Related Behaviors of Mothers of Preschool- and School-Aged Children: A Randomized Controlled Trial

BackgroundAlthough social media such as blogs are still considered innovative communication technologies, some registered dietitians (RDs) are using them to promote healthy eating; however, evidence regarding the effects of healthy eating blogs on users’ diet is lacking.ObjectiveThis study evaluated the effects of an evidence-informed healthy eating blog written by an RD on dietary intakes, with a focus on vegetables and fruit and milk and alternatives consumption, and food-related behaviors of Canadian mothers.DesignThis study was a parallel, randomized, controlled trial.Participants/settingData were collected from 84 French-speaking adult mothers of children aged between 2 and 12 years living in Quebec City, Quebec, Canada, who were recruited between October 2015 and February 2017 using institutional e-mail lists, flyers, newspapers, social media advertisements, and word of mouth.InterventionThe intervention was exclusively delivered through an evidence-informed healthy eating blog—integrating theory-based intervention methods to improve diet quality by increasing vegetables and fruit and milk and alternatives consumption in mothers—for 6 months at a dose of one new post written by an RD each week. Mothers could engage with the RD and fellow participants by posting comments on the blog.Main outcome measuresMain outcomes were daily intakes of vegetables and fruit and milk and alternatives. Outcome assessments were performed at baseline, 3 months, and at the end of the 6-month intervention.Statistical analysisDifferences between the groups were examined using mixed linear models.ResultsAt 6 months, no significant difference was observed between groups for intakes of vegetables and fruit (P=0.923), milk and alternatives (P=0.271), or food-related behaviors and body weight (P=0.180).ConclusionsA healthy eating blog, at a dose of 1 post per week, had no effects on dietary intakes, food-related behaviors, and body weight of mothers after 6 months. Methodologic issues are discussed to inform future health behavior research using blogs to promote healthy eating.     

Pilot Clinical Trial of Time-Restricted Eating in Patients with Metabolic Syndrome

Metabolic syndrome (MetS) and erratic eating patterns are associated with circadian rhythm disruption which contributes to an increased cardiometabolic risks. Restricting eating period (time-restricted eating, TRE) can restore robust circadian rhythms and improve cardiometabolic health. We describe a protocol of the Time-Restricted Eating on Metabolic and Neuroendocrine homeostasis, Inflammation, and Oxidative Stress (TREMNIOS) pilot clinical trial in Polish adult patients with MetS and eating period of ≥14 h/day. The study aims to test the feasibility of TRE intervention and methodology for evaluating its efficacy for improving metabolic, neuroendocrine, inflammatory, oxidative stress and cardiac biomarkers, and daily rhythms of behavior for such population. Participants will apply 10-h TRE over a 12-week monitored intervention followed by a 12-week self-directed intervention. Changes in eating window, body weight and composition, biomarkers, and rhythms of behavior will be evaluated. Dietary intake, sleep, activity and wellbeing will be monitored with the myCircadianClock application and questionnaires. Adherence to TRE defined as the proportion of days recorded with app during the monitored intervention in which participants satisfied 10-h TRE is the primary outcome. TREMNIOS will also provide an exploratory framework to depict post-TRE changes in cardiometabolic outcomes and behavior rhythms. This protocol extends previous TRE-related protocols by targeting European population with diagnosed MetS and including long-term intervention, validated tools for monitoring dietary intake and adherence, and comprehensive range of biomarkers. TREMNIOS trial will lay the groundwork for a large-scale randomized controlled trial to determine TRE efficacy for improving cardiometabolic health in MetS population.     

Enhanced Eating Competence Is Associated with Improved Diet Quality and Cardiometabolic Profile in Finnish Adults with Increased Risk of Type 2 Diabetes

Eating competence (EC) is characterized by positive attitudes towards food and eating, having regular meals, eating a variety of foods, and internally regulated eating. We investigated the associations of changes in EC with changes in lifestyle, anthropometrics and biomarkers of glucose and lipid metabolism in 2291 adults at increased risk of type 2 diabetes as part of the StopDia study conducted in primary healthcare. EC and diet quality were assessed with validated digital questionnaires. During the intervention, the participants received either (1) the digital lifestyle intervention, (2) the combined digital and face-to-face group-based lifestyle intervention, or (3) standard care. EC increased among the participants independent of the intervention type. Increase in EC was associated with an increase in diet quality, high-density lipoprotein (HDL) cholesterol, and with a decrease in body mass index and waist circumference, regardless of baseline EC. Of the subdomains of EC, the contextual skills, food acceptance and eating attitudes were associated with various of these changes. Our results thus suggest that EC could be a potential target in lifestyle interventions aiming to improve the cardiometabolic health of people at type 2 diabetes risk.     

Vegetable Variety Is a Key to Improved Diet Quality in Low-Income Women in California

Primary prevention education interventions, including those sponsored by the US Department of Agriculture for low-income families, encourage and support increases in vegetable intake. Promoting vegetable variety as a focal point for behavior change may be a useful strategy to increase vegetable consumption. A simple vegetable variety evaluation tool might be useful to replace the time-intensive 24-hour dietary recall. The purpose of our study was to determine whether vegetable variety is associated with vegetable consumption and diet quality among US Department of Agriculture program participants. Variety of vegetable intake and measures of total vegetable intake, diet quality, and diet cost were evaluated. Low-income, female participants (N=112) aged 20 to 55 years with body mass index 17.7 to 68.5 who were the primary food purchasers/preparers for their households were recruited from four California counties representing rural, urban, and suburban areas. Energy density and Healthy Eating Index-2005 were used to assess diet quality. Vegetable variety was based on number of different vegetables consumed per week using a food frequency questionnaire, and three groups were identified as: low variety, ≤5 different vegetables per week; moderate variety, 6 to 9 vegetables per week; and high variety, ≥10 vegetables per week. Compared with the low-variety group, participants in the high-variety group ate a greater quantity of vegetables per day (P<0.001); their diets had a higher Healthy Eating Index score (P<0.001) and lower energy density (P<0.001); and costs of their daily diet and vegetable use were higher (P<0.001). Thus, greater vegetable variety was related to better overall diet quality, a larger quantity of vegetables consumed, and increased diet cost.     

Diet-Related Behaviors and Diet Quality among School-Aged Adolescents Living in Greece

Prevalence of diet-related behaviors (i.e., breakfast consumption, eating with the family) and their association with a 17-point diet quality score, constructed on the basis of reported frequency (in days/week) of vegetable, fruit, sweets and sugar-sweetened beverages consumption, was investigated among 3525 adolescents (51.5% girls) aged 11, 13 and 15 years, who were participants in the Greek arm of the international Health Behaviour in School-Aged Children (HBSC) cross-sectional study, during 2018. Almost one-third (32.9%) of the sample had breakfast ≤1 day/weekdays, 20.2% rarely ate with the family, 26.1% had a meal while watching TV ≥5 days/week, 31.7% had a snack in front of a screen ≥5 days/week and 24.1% ate in fast-food restaurants at least once/week. Multivariable ordinal logistic regression revealed that eating breakfast ≤1 day/weekdays compared to 4–5 days/weekdays (Odds ratio (OR): 1.56, 95% con-fidence interval (CI): 1.34–1.82), eating rarely with the family compared to almost every day (OR: 1.35, 95% CI: 1.13–1.60) and eating in fast-food restaurants ≥2 times/week vs. rarely (OR: 4.59, 95% CI: 3.14–6.70) were associated with higher odds of having poor diet quality. High frequency of having meals/snacks in front of a screen/TV was also associated with poor diet quality. Efforts to prevent or modify these behaviors during adolescence may contribute to healthier diet.     

Development of a novel mindfulness and cognitive behavioral intervention for stress-eating: A comparative pilot study

Stress-related eating is increasingly cited as a difficulty in managing healthy eating behaviors and weight. However few interventions have been designed to specifically target stress-related eating. In addition, the optimal target of such an intervention is unclear, as the target might be conceptualized as overall stress reduction or changing emotional eating-related thoughts and behaviors. This pilot study compared the effects of three interventions targeting those components individually and in combination on stress-related eating, perceived stress, and weight loss to determine whether the two intervention components are effective alone or are more effective when combined. Fifty-three overweight participants (98% female) who reported elevated levels of stress and stress-eating and were at risk for obesity were randomly assigned to one of three six-week interventions: a modified mindfulness-based stress reduction (MBSR) intervention, a cognitive behavioral stress-eating intervention (SEI), and a combined intervention that included all MBSR and SEI components. All three interventions significantly reduced perceived stress and stress-eating, but the combination intervention resulted in greater reductions and also produced a moderate effect on short term weight loss. Benefits persisted at six week follow-up. The pattern of results preliminarily suggests that the combination intervention (MBSR + SEI) may yield promise in the treatment of stress-related eating.     

Effectiveness of a Diet and Resistance Exercise Intervention on Muscle Health in Older Adults: ProMuscle in Practice

ObjectivesClinical studies show that resistance exercise and a protein-rich diet can counteract the age-related decline of muscle mass, strength, and physical performance. The aim of the ProMuscle in Practice study was to test effectiveness of a resistance exercise and dietary protein intervention for older adults implemented in a real-life setting.DesignA randomized controlled multicenter intervention study.Setting and ParticipantsOne hundred sixty-eight community-dwelling older adults were included (age 75 ± 6 years). A 12-week intensive support intervention including progressive resistance exercise supervised by a physiotherapist and dietitian guidance on increasing protein intake was followed by a voluntary 12-week moderate support intervention to continue the adapted lifestyle pattern. The control group received no intervention.MethodsCompliance was measured through attendance lists and 3-day food records. Physical functioning, leg strength (3-repetition maximum, knee extension strength), lean body mass [(LBM) dual-energy X-ray absorptiometry], and quality of life (5-level EQ-5D) were measured at baseline, and after 12 and 24 weeks. Differences in change between groups were assessed with linear mixed model analysis.ResultsThe intervention group increased protein intake and attended 83.6% of the training sessions. Short Physical Performance Battery score slightly increased in intervention participants [from 10.1 (95% confidence interval 9.7–10.5) to 10.4 (10.0–10.8) at week 12 and 10.6 (10.2–10.9) at week 24], where control participants decreased (time × treatment interactions, P < .05). Improvements in intervention group compared with controls were also observed for Timed Up-and-Go, strength and LBM at both time points (time × treatment interactions, P < .05). No difference between groups was found for the 6-Minute Walking Test, activities of daily living, and quality of life.Conclusions and ImplicationsProMuscle in Practice was effective on improving muscle strength and LBM, with small changes in the composite function score in community-dwelling older adults in a real-life setting. Further research should explore feasibility of real-life implementation, as well as improving long-term compliance.     

The effect of a mindful restaurant eating intervention on weight management in women

ObjectiveTo evaluate the effect of a Mindful Restaurant Eating intervention on weight management.DesignRandomized control trial.SettingGreater metropolitan area of Austin, Texas.ParticipantsWomen (n = 35) 40-59 years old who eat out at least 3 times per week.InterventionThe intervention, using 6 weekly 2-hour, small group sessions, focused on reducing calorie and fat intake when eating out through education, behavior change strategies, and mindful eating meditations.Main Outcome MeasuresWeight, waist circumference, self-reported daily calorie and fat intake, self-reported calories and fat consumed when eating out, emotional eating, diet related self-efficacy, and barriers to weight management when eating out.AnalysisGeneral linear models examined change from baseline to final endpoint to determine differences in outcomes between the intervention and control group.ResultsParticipants in the intervention group lost significantly more weight (P =.03), had lower average daily caloric (P = .002) and fat intake (P = .001), had increased diet-related self-efficacy (P = .02), and had fewer barriers to weight management when eating out (P = .001).Conclusions and ImplicationsMindful Restaurant Eating intervention was effective in promoting weight management in perimenopausal women.     

Experimentally increasing sedentary behavior results in decreased sleep quality among young adults

ObjectiveSleep has been shown to influence cardiometabolic function, and physical activity and sedentary behavior have both been shown to epidemiologically influence sleep. However, no study has experimentally evaluated the effects of sedentary behavior on sleep quality, which was this study's purpose.MethodsThis study employed a 2-group parallel randomized controlled intervention protocol; young adult (18–35 years old) participants confirmed to be active were randomly assigned into a sedentary behavior intervention group (n = 26) or a control group (n = 13). The intervention group was asked to minimize steps to ≤5000 steps/day for one week whereas the control group was asked to continue normal physical activity levels for one week. Both groups completed the Pittsburgh Quality Sleep Index (PSQI) pre- and post-intervention. The intervention group resumed normal physical activity levels for one week post-intervention.ResultsA significant group × time interaction effect was observed (F = 4.49, P = 0.04), with contrast tests indicating significant PSQI change score in the intervention group. Specifically, PSQI scores significantly decreased by 3.16 points (representing improved sleep quality) from Visit 2 to Visit 3 (P < 0.001) in the intervention group.ConclusionActive young adults who removed structured exercise and significantly decreased their step counts (e.g., increased their amount of time spent being sedentary) for one week experienced significant decreases in sleep quality. The present findings underscore the importance of maintaining regular physical activity for optimal sleep quality.     

Contributions of Early Care and Education Programs to Diet Quality in Children Aged 3 to 4 Years in Central North Carolina

BackgroundParents and early care and education (ECE) are the key influencers of young children’s diets, but there is limited information about how each contribute to children’s overall diet quality.ObjectiveThis study aimed to determine what proportion of children’s dietary intake occurs within the ECE setting and whether diet quality is higher at ECE centers and, consequently, on weekdays than weekends.DesignThis cross-sectional analysis of a larger cluster randomized controlled trial used multiple 24-hour dietary intakes measured through a combination of the Dietary Observation in Child Care protocol and parent-reported food diaries.Participants/settingParticipants (N=840) included children aged 3 to 4 years enrolled in ECE centers in central North Carolina for whom 24-hour dietary intake was captured via observation of meals and snacks consumed at ECE and parent-report of all remaining meals and snacks. Data were collected from 2015 to 2016.Main outcome measuresDiet quality at ECE and elsewhere was evaluated using the Healthy Eating Index 2015.Statistical analyses performedMixed-effects models were used to determine differences in mean Healthy Eating Index 2015 component and total scores. Models were adjusted for children’s age and sex and accounted for clustering within ECE centers and families.ResultsChildren consumed approximately 40% of daily energy, nutrients, and food groups at ECE centers. The mean total Healthy Eating Index 2015 score was higher for foods and beverages consumed at ECE centers (58.3±0.6) than elsewhere (52.5±0.6) (P<0.0001). The mean total Healthy Eating Index 2015 score was also higher on weekdays (58.5±0.5) than on weekends (51.3±0.5) (P<0.0001).ConclusionsChildren consume a majority of dietary intake away from ECE centers. Overall, diet quality is low, but the quality of foods consumed by children at ECE centers is higher than that consumed elsewhere. ECE centers remain an important source of nutrition and further investigation is warranted to identify ways to support both ECE centers and families to provide healthier eating environments.     

Eating Timing: Associations with Dietary Intake and Metabolic Health

BackgroundEmerging research indicates that eating timing may influence dietary intake and metabolic health. However, studies to date have not examined the association of multiple measures of eating timing with both dietary intake and metabolic health in adults with overweight and obesity.ObjectiveTo examine the association of multiple measures of eating timing with dietary intake (ie, dietary composition, diet quality, and eating frequency) and metabolic health (ie, body composition and cardiometabolic risk).DesignThis is a cross-sectional analysis of baseline data from a weight loss and maintenance intervention collected from May 2015 to January 2018.Participants/settingParticipants were women with overweight or obesity who were dependents of active duty and retired military personnel (N = 229; mean ± standard error, BMI = 34.7 ± 0.4 kg/m², age = 40.9 ± 0.7 years). The study was conducted at military installations in Massachusetts, Connecticut, New York, Colorado, and Kentucky.Main outcome measuresEating timing variables examined included daily eating interval (time between first and last eating occasion), time-restricted eating (≤11 hours daily eating interval), early energy eaters (eating ≥60% of energy during the first half of time awake), and bedtime eaters (eating within 2 hours of bedtime).Statistical analysisThe main analysis was limited to those reporting plausible energy intake (64% of total sample [n = 146]). Linear, quantile, or logistic regression models were used to determine the association of eating timing with measures of dietary intake and metabolic health.ResultsIn individuals reporting plausible energy intake, each additional 1 hour in daily eating interval was associated with 53 kcal higher energy intake, higher glycemic load, eating frequency, and waist circumference (P < 0.05 for all). Significant associations were observed for: time-restricted eating and a lower energy intake, glycemic load, and eating frequency; early energy eating and higher carbohydrate intake; bedtime eating and a higher energy intake, glycemic load, and eating frequency.ConclusionsThese findings lend support for the mechanistic targeting of eating timing in behavioral interventions aimed at improving dietary intake and body composition.     

Benefits of Adding an Aquatic Resistance Interval Training to a Nutritional Education on Body Composition,Body Image Perception and Adherence to the Mediterranean Diet in Older Women

The human population is increasing due to lengthening life expectancy, but the quality of life and health of people is moving in the opposite direction. The purpose of this study is to evaluate how aquatic resistance interval training can influence body composition, body image perception and adherence to the Mediterranean diet (MD) in older women participants in a nutrition education program and to study the relation between these variables. Thirty-four participants aged 69 ± 4 years were randomly assigned into two groups: experimental (aquatic resistance interval training plus nutritional intervention) and control (nutritional intervention). The intervention consisted of resistance training in an aquatic environment carried out for 14 weeks (three sessions per week; 60 min each). Body composition, body image perception and adherence to MD diet were evaluated at baseline and 14 weeks. No significant differences were found between groups regarding body image perception and adherence to the MD. There was a significant increase in muscle mass (kg) (p < 0.001) and a significant decrease in fat mass (kg) (p < 0.001) in the intervention group when compared to the control group. The addition of aquatic resistance interval training to a nutritional intervention was not sufficient to change body image perception and adherence to MD but produced improvement in body composition (through an increase in muscle mass and decrease on fat mass) in older women.     

A Randomized Intervention of Supplemental Nutrition Assistance Program–Education Did Not Improve Dietary Outcomes Except for Vitamin D Among Lower-Income Women in Indiana

BackgroundThe goal of US Department of Agriculture Supplemental Nutrition Assistance Program–Education (SNAP-Ed) is to improve the likelihood that those eligible for SNAP will make healthy choices aligned with the Dietary Guidelines for Americans, 2020-2025.ObjectiveThe objective of the study was to evaluate the long-term effects of a direct SNAP-Ed intervention in which participants actively engage in learning with educator instruction about dietary quality and usual intake of key nutrient and food groups among Indiana SNAP-Ed–eligible women participants as an example sample in the context of no similar existing evaluation.DesignThe study design was a parallel-arm, randomized controlled, nutrition education intervention, with follow-up at 1 year.Participants/settingParticipants (18 years and older; n = 97 women) eligible for SNAP-Ed and interested in receiving nutrition education lessons were recruited from 31 Indiana counties from August 2015 to May 2016 and randomized to an intervention (n = 53) or control (n = 44) group.InterventionThe intervention comprised core lessons of Indiana SNAP-Ed delivered between 4 and 10 weeks after baseline assessment. Each participant completed a baseline and 1-year follow-up assessment. Dietary intake was assessed using repeated 24-hour dietary recalls (up to 2).Main outcome measuresMean usual nutrient, food group intake, diet quality (ie, Healthy Eating Index-2010 scores), and proportion of intervention and control groups meeting Dietary Guidelines for Americans, 2020-2025 recommendations and Dietary Reference Intake indicators of requirement or adequacy, were determined using the National Cancer Institute method and the simple Healthy Eating Index-2010 scoring algorithm method. Dietary changes between intervention and control groups were examined over time using mixed linear models.Statistical analyses performedBonferroni-corrected significance levels were applied to the results of the mixed linear models for comparisons of usual intake of nutrients and foods.ResultsNo differences in diet quality, intake of food group components, food group intake, or nutrients were observed at 1-year follow-up, except that vitamin D intake was higher among those who received SNAP-Ed compared with the control group.ConclusionsA direct SNAP-Ed intervention did not improve diet quality, food group intake, or key nutrient intake, except for vitamin D, among Indiana SNAP-Ed–eligible women up to 1 year after the nutrition education.     

Eight weeks of intermittent fasting versus calorie restriction does not alter eating behaviors,mood, sleep quality,quality of life and cognitive performance in women with overweight

Human trials that compare intermittent fasting (IF) to calorie restriction (CR) with psychological, behavioral and cognition outcomes are limited. We hypothesized that there would be no difference between CR and IF on perceived eating behaviors, mood, sleep quality, quality of life (QOL) and cognition in women with overweight and obesity. In this prespecified secondary analysis of an open-label, single center, parallel assignment, randomized controlled trial, healthy women with overweight or obesity (N = 46, mean [SD] age 50 [9] years, BMI 32.9 [4.4] kg/m²), without a diagnosed eating disorder and who were randomized into 2 weight loss groups (prescribed 70% of calculated energy requirements as IF or CR) were included. Measurements were assessed in both IF and CR groups following a 12-hour overnight fast during baseline and week 8 and additionally following a 24-hour fast in the IF group only at week 8. We observed that IF produced greater weight and body fat loss than CR (P < .001). We did not detect any statistical difference between groups for the change in dietary restraint, disinhibition, hunger, mood, sleep quality, and QOL. An increase in cognitive performance was found in both IF (P = .036) and CR (P = .006) groups in one of the cognitive tasks, but there was no statistical difference between groups. Perceived eating behaviors, mood, sleep quality and cognitive performance were not changed by an acute 24-hour fast within the IF group (all P > .05). IF may be a viable alternative to CR for weight loss, in the short-term, without adversely impacting eating behaviors, mood, sleep quality, QOL or cognition in healthy women with overweight or obesity. However, larger and long term trials are required.     

Stress,Depression, Social Support,and Eating Habits Reduce Diet Quality in the First Trimester in Low-Income Women: A Pilot Study

Maternal diet quality influences birth outcomes. Yet, little research exists that assesses women's diet quality during the first trimester of pregnancy, a crucial time of placental and fetal development. This cross-sectional study, describing diet quality and its relationship with stress, depression, social support, and eating habits in the first trimester, may identify low-income women needing intensive dietary intervention. Seventy-one low-income women completed validated instruments measuring stress, depression, social support, and eating habits; had their height and weight measured; received training on portion-size estimation; and completed three 24-hour dietary recalls (1 weekend day and 2 nonconsecutive weekdays) from July 2009 to February 2010. Comparative and correlational analyses were done. Women with diet quality scores below the median (n=35) had more depression (9.6±5.1 vs 6.7±5.1) and stress (22.1±5.4 vs 19.3±4.8) and less control over meal preparation (5.0±1.5 vs 4.2±1.5) and support from others (52.0±12.0 vs 57.4±7.2) than did women with high diet quality scores (n=36). Diet quality was negatively related to depression (r=?0.41), stress (r=?0.35), skipping meals (r=?0.41), and control over meal preparation (r=?0.33), and positively related to support from others (r=0.38). Low-income women experiencing life stressors represent an at-risk group for low diet quality and may need intensive dietary intervention before and during pregnancy. More research designed to improve diet quality in low-income pregnant women is needed.     

Does Timing Matter? A Narrative Review of Intermittent Fasting Variants and Their Effects on Bodyweight and Body Composition

The practice of fasting recently has been purported to have clinical benefits, particularly as an intervention against obesity and its related pathologies. Although a number of different temporal dietary restriction strategies have been employed in practice, they are generally classified under the umbrella term “intermittent fasting” (IF). IF can be stratified into two main categories: (1) intra-weekly fasting (alternate-day fasting/ADF, twice-weekly fasting/TWF) and (2) intra-daily fasting (early time-restricted eating/eTRE and delayed time-restricted eating/dTRE). A growing body of evidence indicates that IF is a viable alternative to daily caloric restriction (DCR), showing effectiveness as a weight loss intervention. This paper narratively reviews the literature on the effects of various commonly used IF strategies on body weight and body composition when compared to traditional DCR approaches, and draws conclusions for their practical application. A specific focus is provided as to the use of IF in combination with regimented exercise programs and the associated effects on fat mass and lean mass.     

Dietary intervention in chronic fatigue syndrome

Background Anecdotal reports and books have been published linking an over growth of Candida Albicans with chronic fatigue syndrome (CFS), suggesting dietary change as a treatment option. Little scientific data has been published to validate this controversial theory. This study aims to determine the efficacy of dietary intervention on level of fatigue and quality of life (QoL) in individuals with CFS. Methods A 24‐week randomized intervention study was conducted with 52 individuals diagnosed with CFS. Patients were randomized to either a low sugar low yeast (LSLY) or healthy eating (HE) dietary interventions. Primary outcome measures were fatigue as measured by the Chalder Fatigue Score and QoL measured by Medical Outcomes Survey Short Form‐36. Results A high drop out rate occurred with 13 participants not completing the final evaluation (7HE/6LSLY). Intention to treat analysis showed no statistically significant differences on primary outcome measurements. Conclusion In this randomized control trial, a LSLY diet appeared to be no more efficacious on levels of fatigue or QoL compared to HE. Given the difficulty with dietary compliance experienced by participants, especially in the LSLY group, it would appear HE guidance is a more pragmatic approach than advocating a complicated dietary regime.
