Epidemics of fatal pulmonary hypertension and heart valve damage associated with pharmaceutical anorectic agents have led to the withdrawal of products from the market. This was the case with aminorex in the 1960s, and again in the 1990s with fenfluramine (see: Fen-phen).[5] Likewise, association of the related appetite suppressant phenylpropanolamine with hemorrhagic stroke led the Food and Drug Administration (FDA) to request its withdrawal from the market in the United States in 2000, and similar concerns regarding ephedrine resulted in an FDA ban on its inclusion in dietary supplements in 2004. A Federal judge later overturned this ban in 2005 during a challenge by supplement maker Nutraceuticals. It is also debatable as to whether the ephedrine ban had more to do with its use as a precursor in methamphetamine manufacture rather than health concerns with the ingredient as such.

DON'T drink fruit juice! This is one source of "sugar" that you need to rid yourself of. Fruits are fantastically good for you, providing you the water-rich fiber your body needs, along with so many important nutrients as well. But if you drink the juice, and eliminate the fiber within (such as OJ, apple juice, pineapple juice, etc.), then you are basically mainlining all the simple sugars naturally contained in the fruit. Much better to eat the fruit as is, or opt for fresh vegetable juice instead;

These weight-loss tea leaves are partially oxidized (black teas, for instance, are fully oxidized), lending a smooth, but bold taste to the brew. Happily, they also help boost your body’s ability to metabolize fats, reports a 2009 study from Chinese researchers. When obese and overweight participants consumed oolong for six weeks about two-thirds lost more than 2.2 pounds and 12 percent belly fat. Bonus: They ended the study with healthier cholesterol and triglyceride scores, all adding up to a stronger ticker. (Here are 23 tricks to flatten your belly without exercise.)
Also some research shows that the human body is primed to consume most of its calories during daylight hours. But the lifestyle is problematic for many: Because family meals and dinners with friends often are scheduled for after sunset, "people who try to stop eating after 7pm can’t do it every day for the rest of their lives," says Dr. Seltzer, who supports an alternative strategy: Eating a hearty meal at your regular dinnertime.
