It is said that bitter gourd is very thin, but two or three bitter melons should be eaten raw a day. You must eat them raw. I tried, it was bitter, but the effect was good, but I didn't insist.
In fact, when I lost the most weight, it was when I was lovelorn. I went from 100 to 90 kg at once. I don't want to drink tea every day, but I'd better not. I am thin but sad.
My weight has been around 98 kg now. In fact, I think this figure is actually very healthy as long as it can be maintained. Don't deliberately lose weight.
As for the small belly, I mind you doing sit-ups. It's too hot now. Do it before taking a bath, and then take a bath after a rest. This is good for your health. When it is cold, do it before going to bed. The standard is when you are very tired, about thirty or forty times, and then insist on doing it ten times, which is the most useful. If you are tired every time, you will give up all your efforts. Remember, when you are tired, you must insist on doing more. The more you do, the better the effect, but don't try to be brave.
Well, that's all my experience. If you do as I say, you will lose weight.
