Do not eat. If you feel hungry, drink some water and eat some fruit. If you really can't, you can eat a little, but you must never bring oil or sugar, and you must never eat at night.

If you can persist in this way, you will save exercise, because you have no strength to exercise at all. I tried it myself and brought my own weight loss products.

Don't weigh it a few days ago, because it won't get lighter immediately, and it won't be effective until a week later. My grade is 5 kg a week (of course, my physical condition is different and I will get better grades). I persisted for a month, and of course I won't lose weight like this every week. My one-month grade is 12 kg, which means I feel dizzy when I squat down and stand up, but it's been two months now.

For reference only, don't take it, it hurts.
