I recently used a space capsule to lose weight. I lost 8 pounds a month, and a course of treatment was less than 20 days. There are side effects, but they are not obvious. At first I just felt weak and sweaty. There are no other symptoms now. The principle is to speed up metabolism and burn fat, so people will feel hungry and full, and they can lose weight without dieting. However, you can drink some honey before going to bed at night to prevent constipation.
