Behavioral obesity treatment (BOT) produces clinically significant weight loss and health benefits for many individuals with overweight/obesity and cardiovascular disease (CVD). Yet, about half of patients fall short of expected outcomes and most experience gradual weight regain, thus negating the benefits over time. Lapses (i.e., self-reported eating instances that deviate from the BOT prescribed diet) could explain poor outcomes, but the behavior is understudied because it is difficult to assess in-lab and via self-report. The investigators therefore propose to study lapses using a multimethod approach with the following tools: ecological momentary assessment (EMA; repeated sampling method via mobile device), a wrist-worn device that automatically detects eating behavior and various eating characteristics (frequency, rate, and duration of eating episodes), and 24-hour dietary recalls. The investigators will recruit participants (n=40) with overweight/obesity and one additional CVD risk factor to enroll in a 12-week BOT program and an additional 12-week period of weight loss maintenance. Participants will complete a biweekly 7-day EMA protocol to self-report on eating behavior, including the occurrence of dietary lapse. Participants will continuously wear the wrist-worn ActiGraph Link to characterize eating behavior. Lastly, participants will complete 24-hour dietary recalls via structured interview (split between days with and without lapses) at 6-week intervals to measure the composition of all food and beverages consumed. This study aims to 1) identifying characteristics of lapse behavior by measuring passively-sensed timing, duration, frequency, and rate of eating amongst known lapse episodes, 2) test the association between dietary lapse frequency and weight change, and 3) estimate nutrition composition of dietary lapses. The study approach is consistent with priorities of NHLBI to optimize clinical research and diagnostic strategies to improve CVD and related risk factors.
This project will evaluate the success of the PI's lifestyle medicine practice.
The study represents the first effort to prospectively investigate the Melcap's bio-electrical ingestible ODC system in human. The study goal is to evaluate the safety and feasibility of GES treatment in stomach and in the small and large bowel during and following the ingestion of the bio-electrical capsule under tight and controlled conditions.
Monetary incentive programs can reduce weight short-term; however, many studies have shown weight regain when the incentive program ends. This relapse is unsurprising; it is well-established that a specific behavior is extinguished when reinforcement for the behavior is removed. It is unlikely, then, given the expense, that monetary incentive programs could be implemented long-term for chronic diseases like obesity. Thus, programs are needed to bridge the gap between the short-term effects of a monetary incentive program and long-term effects at program end. A program that could be effective at bridging this gap is thought training, namely, episodic future thinking (EFT). EFT teaches individuals to think prospectively about future events as if they are happening now. EFT can reduce delay discounting (DD) which is defined as discounting larger rewards in the future for smaller rewards now (e.g. people with high DD levels may place more value on eating an unhealthy food now vs. the future health benefits of forgoing the food). It is suggested that EFT increases the value of the future reward and helps individuals make choices with lasting benefits. Given the power of EFT to reduce DD, it is plausible that EFT training during an incentive program could help shift one's thought processes towards the long-term consequences of behavior, promoting behavioral change even after the incentive program ends. Thus, the purpose of this study is to assess whether EFT promotes weight-loss in N=40 parent/child dyads (BMI ≥ 25) after a monetary incentive program ends vs. a control thought training program, Healthy Thinking (HT). We hypothesize: - The EFT and HT group will both have a reduction in BMI for adults/percent over BMI for children, weight, and waist circumference from baseline during the monetary incentives program. - The EFT vs. HT group will have a greater reduction in BMI/percent over BMI, weight, and waist circumference from baseline during the monetary incentives program. - The EFT group will maintain the reduction in BMI/percent over BMI, weight, and waist circumference from baseline after the termination of the monetary incentives program. - The HT group will not maintain the reduction in BMI/percent over BMI, weight, and waist circumference from baseline after the termination of the monetary incentives program. - The EFT vs. HT group will have a reduction in DD over time.
This study determines whether different forms of ketones supplemented prior to a meal lower the triglyceride (fat) content in the blood of overweight and obese individuals. Through a randomized crossover design, participants (n=15) will participate in each of the following three experimental groups (no treatment control, ketone ester, ketone salt), with a 5-14 day washout period between each experimental visit.
This study will compare the low-sodium/low-fat DASH (Dietary Approaches to Stop Hypertension) diet with a very low-carbohydrate diet, helping us to better understand how two different dietary approaches may help participants control their blood pressure, lose weight, and reduce their blood glucose.
Currently, the best behavioral treatments for obesity only work for 50% of adults, and of those who initially succeed, most do not maintain their weight loss. One reason for this failure may be due to neurocognitive deficits found among individuals with obesity, particularly related to executive function, which make it difficult for these adults to adhere to treatment recommendations. The proposed study aims to develop a Novel Executive Function Treatment (NEXT), which when administered prior to the behavioral treatment, could help improve outcomes by addressing the neurocognitive deficits in adults with overweight or obesity.
The coadyouvant efficacy of a combination of cosmetics ingredients in the form of a lipolytic cream with hypocaloric diet and physical activity were assessed and compared with with hypocaloric diet and physical activity for overweight and obesity treatment in patients.
The objective of the present study is to evaluate the effect of a 20-week group intervention program based on acceptance and mindfulness in emotional eating, weight loss, physiological parameters and the level of physical exercise, as well as in the quality-of-life and weight self-stigma of overweight and obese people on the short- and medium-term. Design, participants, and method: A randomized clinical trial comprising a total of 110 overweight or obese (BMI ≥ 25) participants that are receiving medical treatment at Primary Care Centers, 20-65 years, will be included and randomly assigned to standard program (N=55) or standard + intervention program (N=55). The standard program group will receive the treatment as usual (TAU) that comprises 5 sessions (on a monthly basis) that will include a personalized diet and physical exercise recommendations, while the standard + intervention program group will receive the same TAU plus the acceptance and mindfulness-based group intervention program. At baseline prior to randomization, after the intervention, and seven months after the program has finished anthropometric and body composition data, biochemical data in blood, waist circumference, blood pressure, eating habits, level of physical exercise, general health, emotional eating, quality-of-life, weight self-stigma, experiential avoidance, self-compassion level and mindfulness abilities will be evaluated. It is hypothesized that the integrated treatment of obesity implementing a group intervention program based on acceptance and mindfulness could help to reduce the emotional eating, enhance weight loss, improve physiological parameters, increase the level of physical exercise, improve the quality of life and reduce the weight self-stigma of overweight and obese individuals.
Background Atrial fibrillation (AF) affects over 1 million individuals in the UK and results in costs of over £450 million per year to the National Health Service (NHS). Current rhythm control strategies are limited by high recurrences of AF. New strategies tackling more upstream pathophysiological mechanisms are most needed. The incidence and prevalence of AF markedly increase with age, whilst obesity is the strongest modifiable risk factor for AF. Preliminary data in relatively young patients suggest that weight loss programmes may reduce AF burden and improve AF-related symptoms. Such programmes could be a widely-applicable and cost-effective option in AF management if they are also effective in elderly patients with AF, particularly if they also improve physical performance. Aim The aim of this study is to investigate whether, in older overweight/obese AF patients, referral to a weight loss programme with meal replacement & behavioral support can reduce AF-recurrences and improve physical performance compared to usual care. Study design Parallel-group, open-label, multi-centre randomised controlled trial. Elderly individuals (60-85 years) with persistent AF and elevated body mass index (BMI; ≥ 27 kg/m2) will be recruited. Participants will be randomly allocated (1:1) to (a) referral to a meal replacement programme with behavioral support (intervention) or (b) usual care (control) for 32-to-36 weeks. The primary endpoints are AF recurrence and physical performance test (PPT) score. Participants randomised to the study intervention will be referred to a commercial provider (CP) providing the intervention. The co-primary endpoints of AF recurrence & PPT score will be analysed irrespective of compliance during the scheduled treatment period following an intention-to-treat principle.
