But this time, it is an alternative to losing some pounds. I’m referring to phentermine diet pill. Phentermine is another appetite suppressant like hoodia. It stimulates the hypothalamus gland to tell the brain that you are still full. Although Phentermine is approved by America’s FDA since 1959, it should only be used on a short-term and temporary basis. Proper diet and exercise is still the best and safe way to lose weight. Phentermine can be used while trying and choosing the best diet and exercise which will fit your lifestyle. But extra cautions should be applied when using appetite suppressant because it may lead to serious starvation and lose of nutrients and minerals in the body.
