Why does weight loss rebound

Weight loss rebound is usually caused by unscientific weight loss methods, muscle loss, decreased basal metabolism, imbalanced dietary structure, and lack of exercise habits. Common manifestations include rapid weight gain, increased body fat percentage, and loss of appetite, which can be improved by adjusting dietary structure, increasing resistance training, and maintaining regular sleep patterns.

1. Unscientific weight loss methods

Short term extremely low calorie diets or single food weight loss can lead to water and muscle loss, rather than fat consumption. This rapid weight loss can easily trigger the body's self-protection mechanism, and is prone to rebound after returning to a normal diet. It is recommended to adopt a balanced diet, with a daily calorie deficit controlled between 300-500 calories, and a healthy weight loss rate of 0.5-1 kilograms per week.

2. Muscle Loss

Improper weight loss can break down muscle tissue for energy supply. For every kilogram of muscle loss, the daily basal metabolic rate is reduced by approximately 13-30 calories. The decrease in muscle mass directly leads to a reduction in resting energy expenditure, forming a predisposition to obesity. Resistance training can be combined with high-quality protein supplements, such as eggs, chicken breast, etc., with a protein intake of 1.2-1.6 grams per kilogram of body weight.

3. Decreased basal metabolism

Long term insufficient calorie intake can trigger metabolic adaptation in the body, leading to a 15-30% decrease in thyroid hormone levels and a 30-50% decrease in leptin. This metabolic compensation phenomenon can last for several months, and even if the diet is restored, it is easy to accumulate fat. It is recommended to maintain metabolic vitality through intermittent heat cycling and strength training.

4. Dietary structure disorder

Low carbohydrate diet may lead to depletion of glycogen reserves. Once staple food intake is restored, each gram of glycogen will bind to 3 grams of water, causing false weight gain. carbohydrates should be kept at 40-45% of total calories, and low glycemic index foods such as oats and brown rice should be preferred to avoid overeating caused by drastic fluctuations in blood sugar levels.

5. Lack of exercise habits

People who only control their diet and do not exercise have a 3-5 times higher probability of weight rebound within 6 months than those who exercise. Although aerobic exercise can help with short-term weight loss, resistance training is more effective for long-term body fat management. It is recommended to engage in 150-300 minutes of moderate intensity exercise per week, including 2-3 strength training sessions. To prevent weight loss rebound, it is necessary to establish a sustainable lifestyle and avoid extreme dieting. Record daily diet and exercise, regularly measure body fat percentage instead of simply focusing on weight. When encountering a plateau period, the exercise mode can be adjusted, such as changing from uniform running to interval training. Maintain sufficient sleep and water intake for a long time, and if necessary, develop personalized plans under the guidance of a nutritionist. The fluctuation range of weight within 2 kilograms is a physiological adjustment and does not require excessive anxiety.
