A word of advice, don't trust diet pills too much. It's no use telling you for sure, and it's three-point poison. Even if the substances in it are harmless to the body, some diuretics will help you drain water, or substances that clear away heat and toxic materials will help you relax. The water in your body has been drained, so you must have lost weight. There is no need to explain why it is dehydrated, and the word 1000 is omitted. I really don't know why those stars say "XX slimming tea, don't be too thin", and some people buy it for dehydration.

Once you stop taking diet pills, your diet will rebound, so I think proper aerobic exercise and diet will be more effective to lose weight healthily.

These are my personal suggestions for your reference. Because I know that dieters are eager to lose weight, their mood is understandable, but thinking about how to lose weight is the first step.
