Chapter 1: Fundamentals of dietary supplements for weight loss and their effect on the body
1.1 Definition and classification of dietary supplements for weight loss
Bades (biologically active additives) for weight loss are not drugs, but concentrates of natural or identical to natural biologically active substances intended for direct intake or introduction into food products. They are used to correct body weight, accelerate metabolism, reduce appetite and improve overall well -being. It is important to understand that dietary supplements are not a replacement for good nutrition and physical exercises, but serve only to addition to them.
You can classify dietary supplements for various signs, including:
- The mechanism of action: Thermogenics, carbohydrates and fat blockers, appetite suppressors, diuretics, laxatives, lipotropics.
- Composition: Based on plant extracts, vitamins and minerals, amino acids, probiotics and prebiotics.
- Output form: Capsules, tablets, powders, liquids, teas.
Each category has its own characteristics, indications and contraindications, which requires an attentive approach to choosing.
1.2 mechanisms for the action of dietary supplements for weight loss: Scientific review
Various dietary supplements for weight loss affect the body differently, using various mechanisms:
- Thermogenics: Thermogenesis (heat production) in the body increase, which leads to burning more calories. They often contain caffeine, green tea extract, guarana, Sinefrin. Caffeine stimulates the central nervous system, increasing metabolism and reducing the feeling of fatigue. Green tea extract contains epigallocatechin Gallat (EGCG), which is believed to enhance thermogenesis and oxidation of fats. Sinefrin contained in a bitter orange also has a thermogenic effect, but requires caution due to potential side effects on the cardiovascular system.
- Carbohydrate blockers: Inhibit enzymes that split carbohydrates in the intestines, thereby reducing their absorption. The most common ingredient is phaseolamine obtained from white beans. It blocks alpha amylase, the enzyme responsible for the splitting of starch. This can help reduce the glycemic food index and reduce the number of calories absorbed from carbohydrates.
- Fat blockers: Prevent the absorption of fats in the intestines. These include an eagleistat, which is a drug released according to the prescription, as well as some hitosan -based dietary supplements. Orlistat inhibits lipaza, the enzyme necessary for the breakdown of fats. The chitosan, obtained from the shells of crustaceans, binds fats in the digestive tract, preventing their absorption.
- Suppliers of appetite: Reduce the feeling of hunger and craving for food. They can contain fiber, psillium, glucomannan, which increase in volume in the stomach, creating a feeling of satiety. Some also contain hormone-like substances, such as 5-HTP, which affects the level of serotonin, which regulates appetite and mood.
- Diuretics and laxatives: Contribute to the elimination of fluid and the contents of the intestine from the body. It is important to understand that they do not burn fat, but only lead to temporary loss of weight due to dehydration. Long -term use can lead to electrolyte imbalance and other health problems.
- Lipotropiki: Improve fat metabolism and contribute to their splitting. These include L-carnitine, choline, inositol, betaine. L-carnitine plays an important role in transporting fatty acids to mitochondria, where they are used for energy production. Kholin and Inositol participate in the metabolism of fats and cholesterol.
1.3 composition of dietary supplements for weight loss: analysis of the main ingredients
The composition of dietary supplements for weight loss can vary depending on their purpose and manufacturer. Consider the most common ingredients:
- Green tea extract: Contains EGCG, which has antioxidant and thermogenic properties. It can also improve insulin sensitivity and reduce cholesterol.
- Caffeine: A stimulator that increases metabolism, reduces appetite and improves concentration. However, excessive caffeine consumption can lead to insomnia, anxiety and heart problems.
- L-Carnitin: The amino acid that is involved in the transport of fatty acids in mitochondria. It can improve energy metabolism and promote fat burning.
- Hitosan: Polysaccharide obtained from crustacean shells. He binds fats in the digestive tract, preventing their absorption.
- Glucomanan: Soluble fiber, which increases in volume in the stomach, creating a feeling of satiety. It can reduce the appetite and cholesterol.
- CLA (conjugated linoleic acid): Fatal acid, which can improve the composition of the body, reducing the fat mass and increasing muscle mass.
- 5-HTP (5-hydroxyryptophan): Amino acid, which is the predecessor of serotonin, hormone that regulates mood and appetite.
- Chroma Picoline: A mineral that can improve insulin sensitivity and regulate blood sugar.
- Garcinia Extract of Cambodia: Contains hydroxilimonic acid (HCA), which is believed to suppress appetite and blocks the formation of fat.
- Ginger root: It has thermogenic and anti -inflammatory properties. It can also improve digestion and reduce cholesterol.
- Kayensky pepper: Contains capsaicin, which has thermogenic properties and can accelerate metabolism.
1.4 risks and side effects of dietary supplements for weight loss: Assessment and prevention
