When buying things, especially the ones that we take in to our bodies, it is always advisable to check the label or the nutritional contents of the product. In the “ingredients” segment found in containers, the first component mentioned is supposedly the most dominant or the most essential part of the merchandise. In dietary supplements, we see such ingredients as L-canitine, ginko, and fibre which are the active ingredients that cause weight loss.
Various studies regarding the effectiveness of these so-called “active ingredients” have been conducted, some proving to be more effective that the others while, in some research, it is found that ingredients, such as grapeseed extract and lecithin, are commercially promoted even when there is no scientific rationale or scientific evidence that they are effective. The following are constituents that are most commonly heard of, and whether or not they truly work as weight loss agents:
Caffeine, which is probably the most widely consumed drug in the world, is said to work not only as a stimulant but also as a weight loss agents. It is known to free fatty acids in the bloodstream for oxidation which means more fats are used in the energy cycle. Guarana, which is a South American vine leaf, is known to contain a dominant amount of caffeine. Various studies are conducted regarding the effectiveness of caffeine as a weight loss agent when combined with other known weight loss agents such as chromium, ephedrine, and others. However, although most of these studies have positive outcomes, these is no present evidence that guarana alone can be used as a weight loss supplement.
L-carnitine, which is supplied by a normal diet, particularly meat, is a non-essential amino acid. Carnitine is known to transfer fats to mitochondrion for energy production. It is therefore theorized that increasing the amount to L-carnitine in the body can induce the transfer of fats and its conversion to energy. However, no study yet has confirmed this theory, and neither is there one that supports L-carnitine use for long-term weight loss.
Dietary fibre-rich foods are said to be more filling and therefore lead to faster satiation. This decreases the total energy intake of a person. Minor studies have been conducted regarding the effectiveness of supplements containing dietary fibre and they generally have positive outcomes. However, compared to dietary supplements, fibre-rich foods are said to be more helpful in losing weight.
There are number of other ingredients that we usually hear about. When they are being advertised, claims such scientific proofs and studies are stated in order to convince the audience about the product. However, one or two simple studies or experiments cannot actually speak for everyone interested to lose weight. There are inevitable short-comings and limitations in every research and it would pay to become conscious about these before deciding to subscribe to a dietary supplement to make sure that you are not wasting your money on some bogus product.
