High-Fat Breakfast Meal Replacement in Overweight and Obesity: Implications on Body Composition, Metabolic Markers, and Satiety.

ABSTRACT: The purpose of this paper was to determine the effect of replacing breakfast with a high-fat drink on fat mass (FM), lean mass (LM), percent body fat (%BF), visceral fat (VAT), resting metabolic rate (RMR), fuel utilization (RER), blood lipids and satiety in overweight and obese adults. Healthy adults (n = 42; 21 Females; body mass index (BMI): 32.8 ± 4.6 kg·m-2) were randomized to control (CON; n = 21) or meal replacement (MRP; n = 22) groups. Body composition was measured using a four-compartment model; RMR and RER were assessed from indirect calorimetry. The MRP (70% fat) was consumed once daily for eight weeks. For males, there was no change (p > 0.05) in FM (mean difference (MD) = 0.41 ± 1.19 kg], %BF MD = 0.50 ± 1.09%, LM MD = -0.64 ± 1.79 kg, or VAT MD = -0.31 ± 1.36 cm for MRP versus CON. Similarly, no differences for females for FM MD = -0.73 ± 1.37 kg, %BF MD = -0.57 ± 1.26%, LM MD = 0.31 ± 1.37 kg, or VAT MD: -0.83 ± 1.2 cm. HDL was significantly reduced in the MRP group for females (adjusted mean change: -6.41 ± 4.44 units, p = 0.018). There was no effect on RMR or RER. Satiety increased in the afternoon for MRP (p = 0.021). Despite high fat, no negative impact on lipids resulted; increased satiety may be beneficial for controlling afternoon cravings, but does not affect body composition.

Project description:Abstract Objectives To examine the association between meal habits (i.e., eating breakfast every day, usually ≥80% fullness at breakfast, and not eating snacks at night), body composition and the subsequent changes in mood status in young adults. Methods This is a longitudinal follow-up study based on a randomized trial (ClinicalTrials.gov Identifier: NCT03828812). Young adults were recruited based in a university campus in Taipei City, Taiwan. In total, 125 participants were recruited and 103 completed the follow-ups. Measured body composition (TANITA BC-418) and moods (Depression Anxiety Stress Scale, DASS) were assessed at baseline, the third month and 15th month from baseline. Baseline meal habits were based on the participants’ recall of their diets in the month before interview. We used mixed-effect model to test the association of baseline total body fat percentage and trunk body fat percentage and moods during follow-ups, adjusting for age, sex, baseline body mass index (BMI), food security status. Results After controlling for sex, age, BMI, and food security status at baseline, having breakfast every day at baseline was associated with 2.04 (se = 0.78, P = 0.0098) lower anxiety score and with 2.58 (se = 1.26, P = 0.0409) lower stress score at baseline. Meal habits were not associated with the subsequent changes in mood status. As for body composition, one % of trunk body fat replacing one % of non-trunk body fat at baseline was associated with 1.19 (se = 0.57, P = 0.0381) higher depression score, 1.02 (se = 0.47, P = 0.0327) higher anxiety score, 2.06 (se = 0.76, P = 0.0075) higher anxiety score at baseline. One % of non-trunk body fat percentage was associated with 2.60 (se = 1.02, P = 0.0116) lower anxiety score, as trunk body fat % is controlled. Baseline body fat composition parameters were not associated with the temporal changes in mood scores. The significance patterns were similar after adjusting for baseline physical activity level, assessed by International Physical Activity Questionnaire. Conclusions Breakfast habits and body composition, especially trunk body fat, was associated with university-based young adults’ emotional health status.

Project description:BackgroundRecent medical guidelines emphasize the importance of actively treating overweight and obesity with diet and lifestyle intervention to achieve ≥ 5% weight loss in a 6-month period. Commercial programs offer one approach provided there is evidence of their efficacy and safety. This study was conducted to evaluate the effectiveness of the Medifast® 4 & 2 & 1 Plan™ on weight loss, body composition and cardiometabolic risk factors in overweight and obese adults.MethodsA systematic retrospective chart review of 310 overweight and obese clients following the Medifast 4 & 2 & 1 Plan at one of 21 Medifast Weight Control Centers® was conducted. Data were recorded electronically and key data points were independently verified. The primary endpoint was change from baseline body weight at 12 weeks. Within group paired t-tests were used to examine changes from baseline in a completers population. Differences between gender and age subgroups were examined using bivariate t-tests and mixed model regression analyses.ResultsFor the primary endpoint at 12 weeks, body weight among completers (n = 185) was reduced by a mean of 10.9 ± 5.6 kg (-10.1%, p < 0.0001), and at 24 weeks (n = 81) mean weight was reduced by 16.0 ± 7.9 kg (-14.3%). At 12 and 24 weeks, 85% and 96% of those remaining on the plan, respectively, had lost ≥ 5% of their baseline body weight. Lean mass was preserved to within 5% of baseline throughout the 24 weeks, and fat mass represented ≥ 80% of the body weight lost from 12 weeks onward. Men, women, seniors (≥ 65 years), and non-seniors (<65 years) all had significant weight reductions with preservation of lean mass. Significant improvements in blood pressure, pulse and waist-to-hip ratio were observed. Mean weight regain among the subset who entered a formal maintenance phase was <2% during an average follow-up of 34 weeks. The meal plan was well tolerated, and program adherence was >85%.ConclusionsThe 4 & 2 & 1 Plan used at Medifast Weight Control Centers was effective for weight loss, preservation of lean mass and improvement in cardiometabolic risk factors. The plan was generally well tolerated in a broad population of overweight and obese adults. #NCT02150837.

Project description:BackgroundEvidence from experimental and observational studies is limited regarding the most favorable breakfast composition to prevent abdominal fat accumulation. We explored the association between breakfast composition (a posteriori derived dietary patterns) and abdominal obesity among regular breakfast eaters from a Swiss population-based sample.MethodsThe cross-sectional survey assessed diet using two 24-h dietary recalls in a nationally representative sample of adults aged 18 to 75 years. We derived dietary patterns using principal component analysis based on the intake of 22 breakfast-specific food groups. All regular breakfast eaters were predicted an individual score for each identified pattern, and then classified into tertiles (T1, T2, T3). We defined abdominal obesity as waist-to-hip ratio (WHR) ≥ 0.9 in men and ≥ 0.85 in women. Logistic models were adjusted for sociodemographic characteristics, relevant nutrition- and health-related behaviors, and diet quality during the rest of the day.ResultsOf the 2019 included survey participants, 1351 (67%) were regular breakfast eaters. Among them, we identified three breakfast types: 1) 'traditional' - white bread, butter, sweet spread, 2) 'prudent' - fruit, unprocessed and unsweetened cereal flakes, nuts/seeds, yogurt, and 3) 'western' - processed breakfast cereals, and milk. The 'prudent' breakfast was negatively associated with abdominal obesity. After full adjustment, including diet quality during the rest of the day, the association was weaker (T3 vs. T1: OR 0.72, 95% CI: 0.47 to 1.08). People taking a 'prudent' breakfast (in T3) had 1.2% lower WHR compared to people taking a breakfast distant from 'prudent' (in T1) (P = 0.02, fully adjusted model with continuous log-WHR). We found no association between 'traditional' or 'western' breakfasts and WHR (OR 1.00, 95% CI: 0.67 to 1.50 and OR 1.16, 95% CI: 0.79 to 1.71, respectively). Findings were in the same directions for the three breakfast types when defining obesity with waist circumference, waist-to-height ratio, or body mass index (≥ 30 kg/m2, for 'prudent' breakfast: OR 0.51, 95% CI: 0.31 to 0.85).ConclusionsRegular breakfast consumers had less abdominal obesity if their breakfast was composed of fruit, natural cereal flakes, nuts/seeds and yogurt. This association was partly explained by their healthier diet during the rest of the day.Trial registrationISRCTN16778734 .
