Keeping your mouth shut means reducing the intake of high-calorie and high-fat foods and increasing the proportion of low-calorie and high-nutrient vegetables and fruits. By controlling diet, you can reduce calorie intake and achieve the goal of losing weight.
Holding legs is to increase physical exercise, including aerobic exercise and strength training. By increasing exercise, you can burn more calories, promote the burning of body fat, improve heart and lung function and strengthen muscles.
If I have to choose which is more important, I think it is more important to keep my mouth shut. Because controlling diet is the basis of losing weight, and increasing exercise is only an auxiliary role. If you just stretch your legs and don't control your diet, the calorie intake will still be high and the weight loss effect will not be too significant. On the contrary, as long as you control your diet, you can lose weight effectively even if you don't do too much exercise.
To sum up, in the process of losing weight, it is equally important to keep your mouth shut and keep your legs open, and you need to combine them to achieve the best weight loss effect.
