Filter by:Over the years, increasing obesity prevalence represents an important threat to national and global public health. Many strategies studied for weight loss have reported that low-carbohydrate diets showed beneficial effects on weight loss for obese patients. However, individual weight losses have varied widely within low-carbohydrate diet groups due to the influence of gut microbiota, which was found in the previous clinical studies of our team (ChiCTR1800015156). Numerous animal studies and clinical trials have evaluated the impact of probiotics on glucose and lipid metabolism as well as weight-loss interventions. However, the effect of the different probiotic strains may play a different role in the same species. Therefore, our team isolated new strains (Lactobacillus reuteri PLBK1，GDMCC No: 60828、Lactobacillus reuteri PLBK2，GDMCC No: 60829、Lactobacillus gasseri PLBK3，GDMCC No: 60830、Lactobacillus acidophilus PLBK4，GDMCC No: 60831、Bifidobacterium lactis PLBK5，GDMCC No: 60832) from the oral cavity, feces or environment of the Chinese race in the previous study. The mixed solid beverage composed of these five strains has local characteristics and meets the requirements of the national standard for food additives, which has obtained the national food production license (SC10632028100205).In our previous animal experiments, the treatment of compound preparation of the above five strains improve insulin resistance and dyslipidemia effectively in obese mice induced by high-fat diet，which obtained significant weight loss . Nevertheless, clinical trials are needed to be carried out to confirm its clinical effect. Therefore, we aimed to conduct a randomized, double-blind, placebo-controlled prospective study on the basis of previous research. In order to evaluate the efficacy and safety, as well as the effect on glucose and lipid metabolism of low-carbohydrate diet combined with probiotics in obese participants, the study will last for 12 weeks. At the same time, Magnetic Resonance Imaging (MRI) will be used to clarify change in body fat distribution, which may provide more clinical evidence for the application of this program in the prevention and treatment of obesity in the future.
The purpose of this study is to determine the effect of a weight-loss diet on body composition in women who practice reformer pilates for 12 weeks. It compares dietary habits and macro and micronutrient intakes in subjects with and without a weight-loss diet at the start and end of the study.
This study is a single-arm behavioral weight loss intervention for emerging adult women with in-person assessments at 0 (baseline) and 4 months (post-treatment) in addition to EMA data collection regarding risk factors known to interfere with program engagement and weight loss in this high-risk population (e.g., sleep, psychological distress, life events).
Obesity is an ongoing major public health problem in most countries of the world for which the agrifood industry still remains criticized because of the abundant offer of high sugar-lipid-energy dense foods, particularly in the fast-food sector. The resulting societal pressure on the food industry probably explains in part the efforts that have been deployed to seek natural active ingredients and to develop functional foods favorably influencing energy balance. Capsaicin is a food non-nutrient constituent that was shown to decrease appetite sensations and subsequent energy intake. The measurement of heart rate variability revealed an association between the increase in sympathetic nervous system (SNS) activity and the satiating effects induced by capsaicin. This is concordant with the observation that pre-prandial intake of capsaicin, be it in capsules or diluted in tomato juice, increased satiety and reduced energy intake. The objective of this study is to evaluate the long effects of Capsimax on appetite sensations and energy expenditure under conditions of moderate energy restriction and to evaluate the long-term effects of Capsimax on energy intake and expenditure under conditions of moderate energy restriction.
This randomized controlled trial examines the feasibility, acceptability, and preliminary impact of an adapted positive psychology-motivational interviewing (PP-MI) intervention for physical activity among patients who have recently undergone bariatric surgery compared to an enhanced usual care control.

Randomized controlled trial to determine if a 6 months of shared medical appointments will results in clinically and statistically significant weight loss.
The study will include 30 women randomized in two distinct groups: G1: Slow weight loss and G2: Rapid weight loss . The total duration of the program will be different for each group, being over 20 and 10 weeks for G1 and G2, respectively, in attempt to match the groups on amount of weight loss (approximately 20 pounds per subject). Participants who meet the inclusion criteria will be randomized to rapid or slow weight loss groups. The energy deprivation of the rapid and slow weight loss will be in -1000 kcal/day and -500 kcal/day, respectively. Calculated based on the baseline resting energy expenditure (REE; determined by indirect calorimetry) and their physical activity level measured for one week. The diet macronutrient composition will be personalized for each participant based on the results of 2-day energy intake at preliminary session, measured with food items selected from a validated food menu. Individuals will be instructed to maintain the level of energy restriction and macronutrient composition during the diet period, however they will be able to do food exchanges, based on the Canadian Diabetes Association system. It will be measured participant's body weight, body compositions, appetite sensations, resting energy expenditure, energy intake, palatability, olfactory performance, food reward, food reinforcement and impulsivity. Participants will have 7 sessions in total: 1 preliminary, baseline, 7 days of intervention, 3 follow ups and final assessment.
The prevalence of obesity in adolescents is remarkably high, with 38.7% of youth 12-15 years of age and 41.5% of 16-19 year olds meeting criteria for overweight or obesity. Behavioral weight control interventions for adolescents have had limited impact on this field and there is considerably more that needs to be done. Notably, adolescents who have difficulty managing their feelings have been found to consume higher caloric foods and report greater amounts of sedentary time. Poor emotion management among adolescents has also been associated with more rapid weight gain and higher BMI. Data from adolescents with overweight/obesity attending our outpatient weight management program (N=124) indicate that 82% of these youth report emotion regulation scores that are comparable to youth with significant mental health problems. Despite documented relationships between adolescent weight control and emotion regulation, no proven adolescent weight management programs targeting emotion regulation exist. To fill this gap, our laboratory developed and piloted an adolescent weight control intervention (HealthTRAC) that combines two previously tested effective interventions, one targeting emotion regulation skill building, the other focused on behavioral weight control. Findings from our small pilot trial are promising and indicate that the newly created HealthTRAC intervention is acceptable to parents and teens, easy to deliver, and leads to modest weight loss and improved emotion management skills compared to a standard behavioral weight control (SBWC) program. These data suggest that emotion regulation is related to weight management and may assist adolescents with overweight/obesity who are seeking to lose weight. The current multi-site study builds on this previous work and will examine the impact of the developed HealthTRAC intervention on improving emotion regulation skills and reducing adolescent BMI in a larger sample with longer term follow-up (18 months after starting the intervention). Adolescents will receive 27.5 hours of intervention time over a 12- month period. We expect that adolescents enrolled in the HealthTRAC intervention will show greater reduction in BMI over the 12-month program and will sustain these losses up to 18 months after starting the intervention compared to teens enrolled in SBWC. The information learned from this project will help us better understand how helping adolescents manage their emotions can improve weight loss outcomes.
