Filter by:The objective of the study is to examine the extent to which diet/lifestyle change programs with a multidisciplinary team (consisting of a dietician, physician and behaviorist/health coach) that develop healthy behaviors before creating a calorie deficit for weight loss will result in greater weight loss and a longer duration of weight maintenance. It intends to compare the extent of weight loss and weight maintenance in participants who will undergo calorie restriction without prior behavioral interventions to participants that will undergo behavioral interventions prior to starting calorie restriction.
This is a prospective non-randomized unicentric clinical trial, characterized by the inclusion of obese (BMI> 35) male with subfertility (sperm count showing low sperm counts and / or motility and / or morphology and / or DNA fragmentation). Patients selected at the endocrinology obesity HC-FMUSP outpatient will be submitted to very low calorie diet (VLCK) for 6 months, being reassessed clinically and laboratorially monthly.
The prevalence of obesity is rising worldwide, both in low- and high-income countries, including people with HIV (PWH). Semaglutide's efficacy in achieving weight loss in obese PWH is still unexplored. The aim of this study is to assess the efficacy and safety of semaglutide in achieving greater weight loss compared to diet and excercise alone in obese PWH and to explore the effect of semaglutide on the immune function, markers of immune activation, viral reservoir, markers of glucose and lipid metabolism and gut microbiome.
A study to examine post-prandial gut-hormone secretion, meal-induced thermogenesis, fasting plasma metabolomic/lipidomic and cardiovascular indices among surgically managed obese individuals in the long term compared to conservatively managed obese patients.
this study aim to evaluate the role of autologous augmentation for buttock contouring and analyze different aethetic gluteal deformity
Very low-carbohydrate ketogenic diet may have beneficial metabolic and weight loss effects, however, adhering to this diet may be challenging. Keyto is a self-monitoring and app-enhanced intervention to help individuals learn about and monitor their breath acetone (a measure of ketosis) levels to promote dietary change and weight loss. The purpose of this research is to test the Keyto self-monitoring + app intervention against a "standard of care" weight loss dietary app (Weight Watchers). 144 participants will be recruited through Facebook ads, provide online consent, and will be randomized to one of the two conditions. Weight loss after 12 weeks will be assessed as the primary outcome, with weight loss at 24 and 48 weeks being secondary outcomes. Blood samples will be collected at baseline and 12 weeks with optional blood samples at 48 weeks follow up.
The study will be conducted as a parallel randomized controlled intervention trial, initiated by eight weeks rapid weight loss with one of two VLCDs, one week of reintroducing regular foods, and 12 weeks with one of two different ad libitum diets; in total 21 weeks. The study will be blinded for the statistician. Due to obvious different dietary intakes in the two diets, subjects cannot be blinded and neither the study personnel. As the study includes different dietary recommendations the registered clinical dietician advising the subjects cannot be blinded either. In total 110 overweight and obese volunteers will be included.
This study is intended to report changes in the weight and metabolic indicators of the subjects six months after the end of the study for adults with a risk factor of 27 kg/m2 or higher (formerly the research task name[clinicaltrial.gov;NCT03675191]).
A person's genetic code is believed to affect how much weight he/she will lose during diets that vary in carbohydrate and dietary fat content. 'Carbohydrate responders' are hypothesized to lose more weight on diets that are high in carbohydrates, as compared to high in fats. 'Fat responders' are hypothesized to lose more weight on diets that are high in dietary fat, as compared to high in carbohydrates. The purpose of the proposed study is to test these hypotheses in a randomized controlled trial.
Worldwide, a third of adults were overweight in 2016, and 13% were obese. Excess energy intake results in weight gain. Excess fat increases the risk of disease (eg. cardiovascular diseases, type 2 diabetes mellitus (T2DM), hypertension, dyslipidemia, dementia, certain cancers). Modest weight reduction (>5% of body weight) decreases the incidence and progression of many of these diseases. Daily energy restriction or continuous energy restriction (CER) involves diets that have a 500-600 kcal deficit per day resulting in sustainable weight loss. However, adherence is difficult. Diets following a 5:2 intermittent energy restriction (5:2 IER) pattern may be better. Approximately 75% energy restriction is maintained for 2 non-consecutive days/week and normal energy intake is consumed on the remaining 5 days of the week. Significantly reduced fasting insulin concentration and insulin resistance were shown in the 5:2 IER regimen compared with the CER regimen. In this study, normal-weight young participants will be recruited and 5:2 IER and CER will be compared over 2 week periods. Subcutaneous continuous glucose monitoring (CGM) devices will be undertaken. An ad libitum pasta meal will be consumed by participants three hours after the ingestion of breakfast to evaluate the energy intake. Postprandial thermogenesis in response to the test drink will be evaluated.
