Sometimes diet and exercise are just not enough.  Things like emotional eating or eating out of boredom or habit while watching TV can ruin a diet plan.  Some people can follow their plan great all day but when they get home they go off the rails and sabotage all of their good work.  

Phentermine is an amphetamine-like prescription medication used to suppress appetite. It can help weight loss by decreasing your hunger or making you feel full longer.  It is one of the most commonly prescribed weight-loss medications.

Like other prescription weight-loss drugs, phentermine is intended to be used as part of an overall weight-loss plan. It is for people who are obese, and who have failed to lose enough weight with diet and exercise alone — not for people who want to lose just a few pounds.   There are better options available if you need to lose less than 20 lbs.
