Because dieting makes the body's nutrition supply insufficient, the body will naturally adjust and adapt, which is the so-called stagnation period. If one stays the same or increases, dieting, weight loss and fitness will consume muscles first, so that muscles will be converted into sugar and water, and then the muscle content will be reduced before fat consumption, so that you can feel whether your muscles are not as good as before.
Nutritional catering suggests eating more fruits and vegetables and less staple food.
