Can I lose weight without exercising? Is it true

It is true that not exercising can lead to weight loss, but the effects and health risks vary from person to person. The core of weight loss lies in calorie intake being less than expenditure, and weight loss can also be achieved through dietary control. However, exercise plays an irreplaceable role in maintaining metabolic health, shaping, and long-term weight management. Relying solely on diet control for weight loss may have significant short-term effects, especially when using low carbohydrate, high protein, or intermittent fasting methods. Reducing daily calorie intake by 500-750 calories can theoretically lead to a weight loss of 0.5-1 kilogram per week. This method is suitable for individuals with limited mobility, such as those with joint diseases or those in the postoperative recovery period. However, a long-term extremely low calorie diet may lead to a decrease in basal metabolic rate, muscle loss, and even complications such as malnutrition and gallstones. Combining exercise with weight loss is a more scientific and sustainable approach. Aerobic exercises such as brisk walking and swimming can directly burn calories, while resistance training can increase muscle mass and improve resting metabolic rate. Exercise can also improve insulin sensitivity, reduce visceral fat, and decrease the probability of obesity. For individuals with a BMI exceeding 28 or those with metabolic syndrome, simple dietary control is difficult to effectively improve indicators such as blood lipids and blood sugar, and must be accompanied by exercise intervention. A lifestyle that lacks exercise may lead to skin sagging, decreased physical fitness, and other issues even if weight loss occurs.

It is recommended to adopt a weight loss strategy that combines diet and exercise, maintaining a daily calorie deficit of 300-500 calories, and engaging in 150 minutes of moderate intensity aerobic exercise and 2 strength training sessions per week. It is advisable to control the weight loss rate at 0.5-1 kilogram per week. During weight loss, it is necessary to monitor indicators such as body fat percentage and waist circumference to avoid excessive pursuit of weight figures and neglect of physical health. If you have endocrine disorders or long-term weight stagnation, you should consult a nutritionist or endocrinologist in a timely manner.
