I don't know your diet. If you are really determined to lose weight, then I suggest you:

1) No snacks and no drinks.

2) Use oatmeal (not oatmeal) instead of staple food (such as rice and pasta). I recommend you to eat oatmeal from Nestle, and then you can eat beef and fruit properly. I suggest you eat apples, bananas, pineapples and tomatoes, but don't eat too much.

3) Exercise may be relatively difficult for you, but I still hope you can go out and exercise more. It's not good. Take a walk for about an hour after supper. It would be better if you have a favorite sport.

The most important thing to lose weight is to be able to stick to it. As long as you have perseverance, I believe you will lose weight.
