Research on Weight Loss

Garcinia Cambogia
Garcinia cambogia is a plant native to India. The active ingredient is hydroxycitric acid, now incorporated into many commercial weight loss products. First isolated from sugar beets in 1883, the effectiveness of this herb in weight reduction has only gained attention since 1969, when it was discovered that garcinia inhibits the synthesis of fatty acid. No side effects have been reported, as long as the herb is taken in recommended doses (usually not exceeding 1,500 mg per day).

Ephedra
Ephedra may indeed help the body burn fat -- it's known as a thermogenic aid, meaning it raises metabolism and increases heart rate -- that weight-loss potential may come with a risk. Some studies have linked use of the herb to stroke, heart attack, seizures and sudden death. The Food and Drug Administration says it has received more than 1,200 reports of adverse events linked to ephedra, although supplement makers say the health problems could have occurred even if people hadn't taken ephedra.
