Yes, but it is difficult to persist, and it may hurt the stomach and cause malnutrition. It is best to eat less and eat more meals to lose weight, and don't go on a diet blindly. You can choose to have dinner in advance, such as four or five o'clock. After eating, you can eat a handsome posture and exercise. Or have some fruit and vegetable salad for dinner, just don't eat staple food. You can make some salad cans and freshly squeezed juice during weight loss, and you won't get fat at any time.
