Garcinia cambogia extract is quickly becoming a popular ingredient in many weight loss supplements. Many studies have been pointing to strong possibilities that it will help some people to lose weight. But like similar studies, the evidence is not conclusive. Inspite of this it is been cited in many weight loss supplements as been an active ingredient for losing weight.

Garcinia cambogia belongs to the citrus family like oranges and lemons. It is a small tropical fruit that is too sour to eat but the rind is used as a spice in Indian cooking. It is indigenous to India and Africa. The active ingredient usually accredited for weight loss in this fruit is its extract, hydroxycitric acid.

Hydroxycitric acid (HCA) unlike caffeine is not a stimulant. Neither is it an appetite suppressant, both of which work directly on the nerve centers of the brain. Both stimulants and appetite suppressants can have undesired side effects, including causing food binges any time you stop taking them.

Instead, HCA satisfies the body's need for energy and improves the signaling system that the body uses to tell the brain when it has eaten enough. In overweight people this response is often delayed, causing them to continue to eat more than they need.

HCA seems to work best for people who overeat when they are anxious or stressed, as it will give the same calming effect that they get from food. Generally you do not need to eat any special foods when you are taking HCA, and there are no 'forbidden foods'. Choose healthy foods and you should find that you lose weight and fat slowly but steadily without really trying. You can take slightly smaller portions if you wish and choose fruit instead of sugary snacks but you should not need to go hungry. This is a very natural way to lose weight.

Garcinia cambogia extract (HCA) in weight loss supplements is usually combined with chromium. Chromium is a mineral that is often lacking in our diets as we get older and a chromium deficit can contribute to weight gain and possibly diabetes. HCA and chromium seem to work in a positive synergy to regulate the body's blood sugar levels. However if you have diabetes already, you should see your doctor before taking any products containing chromium.

Though HCA shows possibilities it is best to be cautious just like with all other weight loss supplements. For example do not take HCA if you are pregnant or breast feeding. Consult a doctor before giving it to children. You may also want to avoid HCA if you suffer from migraine or arthritis which can be worsened by citrus fruits.

HCA has some significant advantages over many other weight loss supplements ingredients because it has been extensively tested in research laboratories on both human and animal subjects and no side effects have been found. Consequently it is considered a natural weight loss supplement. It is available from many sources online and may be labeled either hydroxycitric acid or garcinia cambogia extract.
