Filter by:The aim of this is study is to evaluate the effects of a single intake of grapes (a polyphenol-rich food) in postprandial metabolism in subjects with obesity, including a first intake (high-fat breakfast) after overnight fasting a second one (medium-fat lunch). Studies on the effects of polyphenols on postprandial (glucidic and lipidic) metabolism have commonly been performed in animal models and have used grape extracts, ignoring the whole pool of polyphenols present in grapes (extractable and non-extractable polyphenols). Besides, the contribution of polyphenols to the so-called second-meal effect has not been explored. It should be highlighted that this study aims to explore the potential beneficial role of fresh grapes, consumed as fruit; in order to ensure the stability of the product, they will be provided as freeze-dried milled material, but the amount received by the subjects could be incorporated into a common diet, being equivalent to 300 g of fresh grapes.
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.
Previous surgery and obesity has disputed as an unfavorable factor during Total Laparoscopic Hysterectomy. The aim of the investigator's study was to assess the effects of previous abdominal surgery and obesity on intra-operative and post-operative outcomes of TLH.
This study proposes to investigate the acceptability and efficacy of intermittent VLED (5:2 diet) plus exercise, compared with the investigator's established Weight Management Programme (WMP), in obese patients with CKD, using feasibility study methodology. Patients will be invited to participate in the parallel arm, single blinded, randomised controlled feasibility study, and randomly allocated to 1 of 2 treatments for 6 months. The experimental arm involves an intermittent modified fasting regimen consisting of VLED (600 kcal/day) on 2 consecutive days, and 5 days each week on a modified diet to maintain an overall energy deficit of 600 kcal/day across the week (5:2 diet). The control arm will be the standard renal WMP with a continuous energy restricted diet aimed at reducing daily energy intake by 600 kcal/day. The feasibility outcomes are: recruitment rate >50%; intervention retention rate at 6 months >60%; dietary intervention compliance; and weight loss. Secondary outcomes include safety, body composition, proteinuria, lipids, blood pressure, and eating desire. Measurements will be made at baseline, midpoint, and twice at endpoint.
Alzheimer's disease (AD) and other forms of dementia are rapidly increasing with the aging of the population, and show a clear preponderance among people with insulin resistance. Metformin, an insulin sensitizer, is being examined in clinical trials as an anti-aging drug. However, very little objective data is available regarding metformin's effect on the brain, a major organ affected by aging.
The aim of this work is to investigate the feasibility of using the modified a ramped position for mask ventilation and endotracheal intubation of obese patients in comparison to the traditional ramped position
This study evaluates the effectiveness of two online Lifestyle Medicine programs. Participants will be randomized by residence, urban vs. rural, into one of two Lifestyle Medicine programs.
Obesity and insulin resistance are worldwide epidemic and taking a major public health toll. Obesity also increases the risk for cognitive impairment which is also an increasing medical, societal, and economic challenge. The ultimate goal of this proposal is to develop a statistical model to assess systemic cross-talk between brain, peripheral tissues, gut microbiota and glucose metabolism. Integrated with exercise training intervention the results will be utilized to provide disease risk profiling and personalized predictions of exercise training as a drug free treatment for insulin resistance and type 2 diabetes.
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.
This study evaluates if promotion of a normocaloric and balanced diet and of physical activity, through an individual- or group-based lifestyle intervention of 12 months, may affect anthropometric measurements and metabolic profile in obese children.
