陷入瘦身-复胖死循环？揭秘背后机制，GLP-1药物或成突围关键

Core Insights - The article emphasizes that weight loss on the scale does not necessarily equate to fat loss, as initial weight loss often comes from water and muscle loss, which can lower the basal metabolic rate and lead to weight regain once normal eating resumes [6][7][8]. Group 1: Weight Loss Strategies - Extreme dieting and excessive exercise can lead to muscle loss and a decrease in metabolic rate, creating a vicious cycle of weight loss and regain [7][8]. - A healthy weight loss goal is approximately 0.5%-1% of body weight per week, equating to 2-5 kg per month, rather than drastic short-term weight loss [7][8]. - Combining a balanced diet with regular exercise is crucial; adequate protein intake and resistance training help preserve muscle mass and enhance fat burning [8]. Group 2: GLP-1 Weight Loss Method - The GLP-1 method, which involves a hormone that regulates appetite and promotes fat loss, has shown effectiveness in weight management and is now approved for weight loss in some cases [9]. - GLP-1 drugs help reduce caloric intake and promote fat breakdown, leading to more sustainable weight loss compared to traditional dieting [9]. - It is important to combine GLP-1 medication with healthy eating and exercise for long-term success, as reverting to unhealthy habits can lead to weight regain [9].
