Why diet pills such as hydroxy-cut or xenadrine and even prescribed such as phentermine cause constipation?

Question

Why do over the counter weight loss pills such as xenadrine and hydroxy-cut cause severe constipation? I used to take Hydroxy-cut daily for three years and never had probs. Now, I suffer from constipation when I try to start on them again. Please no answers telling me how bad diet pills are. I maintain a good diet and exercise and still weigh 60 lbs more than I should. 37 yr old male/6 ft tall/weigh 260 lbs.

Answer 1

OK OK, I won't preach at you for supplementing with diet pills.  Nobody's perfect, not even me.

To answer your question as simply as possible...

Caffeine is a common ingredient if not the main ingredient in most diet supplements.  Caffeine is a well-known culprit of dehydration.  

Dehydration is a major cause of constipation.  

It would be wise to increase your water intake alongside these products to help reduce the chance of constipation.

    

Answer 2

Three steps that have really helped me are dieting, exercising, and the correct weight loss supplement for losing weight. Focus on those three things and you will lose weight considerably. I exercise 30 mins a day along with taking Proactol, a natural weight loss supplement that I saved money on at theweightlossplace.com

Good luck and stay focused = )
