Nutritional supplements – weight loss miracle through hunger suppressants
We are surrounded on the Internet, in magazines and newspapers at least of one advertisement for a weight loss product. There are many weight loss supplements. Many of them have entered the market worldwide, or are even local products for every country. Each is credited with special effects due to its ingredients. What we know about those ingredients?
About hunger suppressants
There are some dietary supplements marketed for their alleged effect on weight loss by influencing appetite. This category of supplements is divided into three subcategories:
In the first subcategory within those products to suppress hunger by increasing CCK (cholecystokinin), a hormone found in connection with the development of satiety. Among these include HCA (Hydroxycitric acid), pine seed oil (contains pinolenic acid) and Hoodia. When taken before food, nutritional supplements from the small intestine stimulates certain cells to release significant amounts of CCK, which send the brain message that enough food has been consumed. Their effectiveness is questionable. HCA has proven to be an effective hunger suppressant. Also pine seed oil has proven to be an effective hunger suppressant. It has the ability to stimulate CCK secretion by up to 60% of normal, thus reducing the amount of food consumed by 36%. Of these three supplements, Hoodia deserves special attention because of potential side effects. The active substance is extracted from a cactus (Hoodia gordonii), it can be safely consumed – this is known for hundreds of years the tribes of southern Africa, which is used to inhibit hunger in times of famine. Laboratory studies have shown that the process of extracting the active ingredient (P57, a steroid glycoside) is accompanied by the emergence of unwanted contaminants that may affect liver function.
The sensation of full stomach
The second subgroup of inhibitors of hunger is composed of indigestible fiber-based products such as guar gum, karaya gum, psyllium and the root of konjac. When taken with water, they swell, forming a gelatinous mass that remains a long indigestible in the stomach, giving the sensation of “fullness”. There are many studies that demonstrate that these fibers can be safely consumed and that are effective, in addition, associate other health benefits, such as regulating blood sugar levels, normalization of bowel movements and improving serum lipid profile. New in this group of products is appetite suppression action proteinase inhibitor (hunger suppressant), known also as the WP2. It is extracted from potato (which is usually avoided in diets). WP2 blocks the action of certain enzymes involved in protein digestion in the gut, slowing the evacuation of gastric contents and enhancing satiety. There are not enough studies to confirm the effectiveness of WP2,
however the performed have shown that those who used this supplement showed a 23% decreased weight than control groups.
The third subgroup of hunger suppressants manifests its effect by acting on emotional factors, tightly linked with appetite and cravings. Overeating, lack of food control and emotional eating in response to numerous problems are initiated by emotional factors and can stand in the way of success of any program to normalize body weight. Nutritional supplements like theanine and 5-HTP (5-Hydroxytryptophan) acts on these emotional components. Theanine, an amino acid found in green tea, is used in anxiety as it was found that the effect of alpha brain waves, inducing a calm mental state. A recent study showed that theanine acts as an inhibitor of appetite in animals. Also suspected that it has the ability to reduce cortisol levels, the most important stress hormone that promotes fat accumulation in the abdominal area. There is scientific evidence obtained from studies showing a link between low serotonin levels and craving for foods high in sugar, and that by normalizing serotonin levels can have a better control of appetite. In this regard, some experts recommend administration of 5-HTP for improving the control of appetite and mental state.
