Yes, you belong to a big base. As long as the diet is well controlled in the early stage, 1 week losing 7 ~ 10 kg is not a problem. For dieters with a large base, my advice is to control their diet first, not to exercise, and then join the exercise when they really can't lose weight. For your diet, it is better to eat a diet with low salt, no oil or less oil, and the weight of staple food will decrease while ensuring the former.

All vegetables, all meat (except fat and skin), boiled water, tea and all fruits are suitable for you, and you can't eat anything else you haven't mentioned ~

If you are more willing to exercise, it will be easier, just exercise for 2~4 hours every day ~
