Weight regain after weight loss is a major problem in the treatment of persons with obesity.In randomized, head-to-head, placebo-controlled trial, we enrolled adults obesity (body-mass index [the kilograms divided by square height meters], 32 to 43) who did not have diabetes. After an 8-week low-calorie diet, participants were randomly assigned for 1 year one four strategies: moderate-to-vigorous-intensity exercise program plus placebo (exercise group); liraglutide (3.0 mg per day) usual...

Abstract Background Identifying and reducing cardiometabolic risks driven by obesity remains a healthcare challenge. The metabolic syndrome is associated with abdominal inflammation predictive of long-term risk developing type 2 diabetes cardiovascular disease in otherwise healthy individuals living obesity. Therefore, we investigated the effects adherent exercise, glucagon-like peptide 1 receptor agonist (GLP-1 RA), or combination on severity syndrome, obesity, following weight loss....

BackgroundNew obesity medications result in large weight losses. However, long-term adherence a real-world setting is challenging, and termination of medication results regain towards pre-treatment body weight. Therefore, we investigated whether loss improved composition are sustained better at 1 year after active treatment with glucagon-like peptide-1 (GLP-1) receptor agonist, supervised exercise program, or both combined for year.MethodsWe conducted post-treatment study extension...

Importance A major concern with weight loss is concomitant bone loss. Exercise and glucagon-like peptide-1 receptor agonists (GLP-1RAs) represent strategies that may protect mass despite Objective To investigate health at clinically relevant sites (hip, spine, forearm) after diet-induced followed by a 1-year intervention exercise, liraglutide, or both combined.

Abstract STUDY QUESTION Does diet-induced weight loss improve semen parameters, and are these possible improvements maintained with sustained loss? SUMMARY ANSWER An 8-week low-calorie was associated improved sperm concentration count, which were after 1 year in men who loss. WHAT IS KNOWN ALREADY Obesity is impaired quality. Weight improves metabolic health obesity, but there a lack of knowledge on the acute long-term effects parameters. DESIGN, SIZE, DURATION This substudy obesity enrolled...

Abstract Weight regain after weight loss remains a major challenge in obesity treatment and may involve alteration of eating sedentary behavior loss. In this randomized, controlled, double-blind trial, adults with were 1:1:1:1 ratio stratified by sex age group (<40 years ≥40 years), to one-year maintenance exercise, the GLP-1 receptor agonist liraglutide, or combination, as compared placebo, low-calorie diet-induced Primary outcome was change body weight, which has been published. Here,...

Abstract Objective The aim of this study was to investigate glucose tolerance, glucagon response, and beta cell function during a 1‐year maintenance period with either exercise, the glucagon‐like peptide‐1 receptor agonist liraglutide, or combination after diet‐induced weight loss. Methods In randomized placebo‐controlled trial, adults obesity (BMI: 32–43 kg/m 2 ) without diabetes underwent an 8‐week low‐calorie diet (800 kcal/d) were 52 weeks aerobic liraglutide 3.0 mg/d, exercise combined,...

The aim was to explore changes during weight maintenance the glucagon-like peptide-1 receptor agonist liraglutide and/or exercise. Methods: Women and men obesity (18-65 years, BMI 32-43 kg/m2) who achieved ≥ 5 loss an 8-week very low-calorie diet (VLCD) were randomized (1) 3 mg/day (LIRA), (2) exercise 150 min/week +...
