I did some research about diet pills and found out that they are REALLY BAD.
1. Disrupt metabolism
In the long run, it will be harder for you to lose weight.
2. Causes nutritional deficiencies
3. Causes heart problems
4. my own opinion: i consumed before (when i was fat) and i always go to the toilet, i think the frequent diarrhea sort of screw my digestive system!
and anyway, some diet pills are really gimmick. i didnt lose any weight at all.
and some people may lose and after they stopped, they gained it all back.
healthy lifestyle, balanced diet and exercise is always the best!
