Raspberry Ketones Vs. Garcinia Cambogia
Losing weight is important for health. Excess body weight is unflattering and it also increases the risk of developing a wide variety of health conditions, including diabetes and cardiovascular disease. However, losing weight can be very difficult. Many people look for help in the form of dietary supplements.
Raspberry Ketones are a group of chemicals extracted from red raspberries. They are used commercially in small amounts to add raspberry flavor and aroma to foods and cosmetics.
A few small animal studies have suggested raspberry ketones might help in weight loss. Mice kept in cages and fed a high-fat diet rapidly become obese. Some studies have shown that these obese mice fed raspberry ketones as part of a weight-loss diet were able to lose their excess weight faster. Other laboratory studies suggest that raspberry ketones may be able to stimulate lipolysis (the breakdown of fats).
Raspberry Ketones are very similar in structure to synephrine. Synephrine is a stimulant that can increase blood pressure, cause a rapid heart beat and produce jitteriness. Some people report experiencing similar symptoms after taking raspberry ketone supplements.
Raspberry Ketones have never been studied in people. It is not known if they are effective in helping people lose weight. Taking small amounts of raspberry ketones as a flavoring agent or in the form of whole raspberries is believed to be safe. However, the safety of taking Raspberry Ketones in large amounts as a dietary supplement is not known.
Garcinia Cambogia is extracted from the rind of a fruit that looks something like a grapefruit-sized green pumpkin. The rinds of these fruits are used in Asian and Indian cooking. They are cured and stored, and are used to add a rich sour flavor to many dishes.
Garcinia Cambogia may naturally inhibit appetite, boost mood and prevent food cravings. Some studies in rats indicate that it increases the amount of serotonin in the brain, which probably mediates all of these effects. There are many anecdotal reports of individuals spontaneously eating less while taking Garcinia Cambogia.
Garcinia Cambogia may also prevent the body from turning ingested foods into fat. A number of studies in animals have reported that it blocks the conversion of dietary carbohydrates into body fat. A fairly large number of animal studies have demonstrated that Garcinia Cambogia not only helps animals lose weight, it also prevents them from gaining excess body fat in the first place.
A number of studies in humans have tested Garcinia Cambogia as a weight-loss aid. A systematic review of all of the published studies identified a total of 12 clinical studies. Overall, the review found that individuals taking Garcinia Cambogia lost, on average, two pounds more than people not taking it. Most of the studies only tracked individuals for a few weeks, so this is two extra pounds lost over three or four weeks of time.
Garcinia Cambogia is almost certainly safe for use. It has been eaten by many people for long periods of time as part of their regular diet in India and Asia. If taken in excess it may cause upset stomach in some people.
As a word of precaution if you are are taking medications, pregnant or nursing you should talk to your doctor before taking any supplements.
Garcinia Cambogia reduces appetite and blocks the conversion of dietary carbohydrates into fat, and the Raspberry Ketones promote the breakdown of body fat already present. However, there have been no clinical studies, not even in laboratory animals, trying out this idea to see if it works.
Raspberry Ketones have not actually ever been tested in people for either effectiveness or safety. Garcinia Cambogia has been thoroughly tested for both safety and effectiveness in promoting weight loss.
