Losing weight should be a long-term thing. Lose weight in a short time and rebound quickly. Don't believe what Lou said, so you will die before you lose weight.
If you want to lose weight within 17 days, you must not have edema first, and of course you must drink plenty of water. Actually, it's diet. You must eat well in the morning. Milk+steamed bread+fruit will do.
A bowl of rice and some vegetarian dishes for lunch. You should eat more of this meal.
Be sure to eat less at night. Same as noon.
You can eat some fruit between meals and drink some white vinegar after meals to speed up metabolism.
In addition, if you can exercise, the effect will be obvious.
That's all I can say. I wish you 17 a great victory. Ha ha!
