Will controlling diet and not exercising lead to weight loss

Simply controlling diet without exercise can lead to weight loss, but there are differences in the effects and health impacts. Reducing calorie intake can indeed lead to weight loss, but lack of exercise may result in muscle loss, decreased basal metabolism, and other issues.

Controlling diet is the fundamental principle of weight loss. When the daily calorie intake is lower than the expenditure, the body will break down fat to provide energy. Adopting a low sugar, low-fat, and high protein diet, combined with moderate amounts of vegetables and fruits, can achieve weight loss in the short term. This method is more friendly to people with time constraints or limited exercise, such as postpartum women or those with joint injuries.

Long term diet control alone may trigger metabolic adaptation, and the body will actively reduce energy consumption to cope with the calorie deficit. Muscle tissue atrophy due to lack of stimulation, leading to a decrease in basal metabolic rate by approximately 10% to 15%. Some people may experience skin sagging, physical decline, and other conditions, with a relatively high probability of rebound. People with weaker gastrointestinal function may also experience discomfort due to sudden changes in their dietary structure.

It is recommended to incorporate moderate exercise such as brisk walking, swimming, and other low-intensity activities while controlling diet. Exercising three or more times a week can help maintain muscle mass and improve fat loss efficiency. Dietary adjustments should be gradual and avoid extreme dieting. You can consult a nutritionist to develop a personalized plan. Regular monitoring of body fat percentage is more valuable as a reference than simply focusing on weight.
