AI Article Synopsis
- After losing weight, many people struggle to keep it off, which is a big issue for those trying to be healthier.
- The text talks about different reasons why people might gain weight back, like changes in immune cells, hormones that control hunger, and how our bodies burn energy.
- It also mentions some ways to help prevent weight gain, like dieting, exercising, and other medical approaches.
Article Abstract
Weight regain after successful weight loss resulting from lifestyle interventions is a major challenge in the management of overweight and obesity. Knowledge of the causal mechanisms for weight regain can help researchers and clinicians to find effective strategies to tackle weight regain and reduce obesity-associated metabolic and cardiovascular complications. This Review summarizes the current understanding of a number of potential physiological mechanisms underlying weight regain after weight loss, including: the role of adipose tissue immune cells; hormonal and neuronal factors affecting hunger, satiety and reward; resting energy expenditure and adaptive thermogenesis; and lipid metabolism (lipolysis and lipid oxidation). We describe and discuss obesity-associated changes in these mechanisms, their persistence during weight loss and weight regain and their association with weight regain. Interventions to prevent or limit weight regain based on these factors, such as diet, exercise, pharmacotherapy and biomedical strategies, and current knowledge on the effectiveness of these interventions are also reviewed.

Introduction: Strategies to address suboptimal weight loss after Roux-en-Y gastric bypass (RYGB) can be developed if at-risk patients are identified in advance. This study aimed to build a pre-surgery prediction nomogram for early prediction of insufficient weight loss (IWL) or weight regain (WR) after bariatric surgery in Chinese patients.
Methods: In this retrospective study, 187 patients with obesity and type 2 diabetes who underwent laparoscopic RYGB were followed yearly for 3 years.

Obesity is associated with significant morbidity, with an estimated prevalence of 42.4% in the USA. Treatment of severe obesity often involves Roux-en-Y gastric bypass and laparoscopic sleeve gastrectomy.

There is controversy about the health risks of sugary diets. A recent study reported that chronic consumption of 11% sugar solutions improved glycemic control in lean mice. Based on this finding, we hypothesized that chronic consumption of the same 11% sugar solutions would also improve glycemic control in metabolically deranged mice.

Aims: To date, bariatric surgery (BS) is the most effective long-term treatment for obesity, but weight regain (WR) is common. The very low-calorie ketogenic diet (VLCKD) is effective for weight loss and may influence gut microbiota (GM) composition, but it has been scarcely evaluated in post-bariatric patients. This study compared the efficacy and safety of a VLCKD in patients with WR post-bariatric surgery (BS+) and in bariatric surgery-naïve patients (BS-).
