1, if the weight loss caused by dieting is about 10 kg, it is obvious from the appearance. Because through dieting, the initial reduction of weight loss is water, protein and so on. And the fat loss is not obvious.

2. If you exercise to lose weight, the change in weight may not be obvious, but it is easier to see the change in appearance. Because in the process of exercise, muscle content is increasing and fat is decreasing, so the weight change is not obvious, but the curve of the body changes obviously.

3, exercise plus diet control, weight loss of about 5 kg should be able to see changes.
