You can lose weight, but don't be too eager to see the effect. Personally, I suggest that you only drink lotus leaves, which are fresh in taste, detoxifying and beautifying. The side effect of senna leaves is a little diarrhea. If you are weak, don't choose Senna. Senna leaves usually have obvious effect on constipation and obesity. There are other herbal teas that also have some regulating effects on the body. You can search for references, but you must first understand your physique and then prescribe the right medicine.
Actually, I suggest you exercise to lose weight. If you want to slim your waist or legs, you can use a hula hoop, point your toes, and then wrap plastic wrap around the parts you want to lose weight. This is better and healthier.
It's bad for your stomach not to eat or only eat fruit in order to lose weight. In addition, I recommend a diet magazine, a women's magazine, and buy it often. I think it's good.
Health comes first. I hope you have a healthy and symmetrical body.
