Fat burners

What are Fat Burners?

The products used to reduce body fat are very popular, despite being designed for athletes who need to reduce their body fat levels of sports competition requirements, as is the case with bodybuilders, boxers and wrestlers and others. In the practice of fitness will be used to accelerate the process of being fit with lower levels of fat, improving the visual appearance of muscular forms, on the other hand, and without entering into controversy, many people use them with the intention of burning fat without getting results.

Let’s review for more substances which are used as fat burners.


The fiber is found mainly in the plant world and can be classified into soluble and pectins and mucilage or insoluble found in whole grains, some fruits and vegetables.

Mainly used in fiber are soluble and semi-soluble dietary and can provide the following benefits:

  • Help create a feeling of fullness, thus to control hunger.
  • Ralentalizan absorption of carbohydrates and their passage into the blood. In some studies, uses fiber to lower the glycemic index of some carbohydrates.
  • Reduce the absorption of fat and cholesterol but also fat-soluble vitamins.
  • Exert a beneficial effect of bowel cleansing.

The recommended daily amount is about 30 grams and most athletes do not reach this recommendation. The fiber must be taken with water, is effective and healthy if we want to reduce fat on our bodies.


The Lipotropics are substances that prevent accumulation of fat especially in the liver and are a great help in the detoxification of metabolic waste and toxins. Some lipotropic act as emulsifiers, making the fat more soluble in blood and therefore can be transported more effectively. Among the most commonly used are lipotropic, methionine, betaine, lipase, choline, inositol and guggulsterones. The guggul plant extract contains guggulsterones, which according to clinical studies seem to decrease the level of fat and cholesterol. The Lipotropics are a great help when we have an excessive accumulation of fat and usually in men and especially visceral fat and impaired liver metabolic functions. It is useful in the early stages of the diet when the fat percentage is high and if you perform aerobic exercises as we will be ready to use fat as energy. The Lipotropics are effective and have no contraindications.

Insulin Enhancers

These are substances that improve insulin sensitivity. In people who are very overweight and physical inactivity are triggers insulin resistance, which is associated with low availability of glucose and an increase in fat accumulation. The optimization of the functioning of insulin allows muscle cells accept more nutrients such as glucose, amino acids and creatine. Moreover, if the body uses only the amount of insulin can control in part the formation of fat and will have more energy.

Among the insulin potentiators known, we can cite the Chromium Picolinate, Vanadium Sulfate and Alpha Lipoic Acid. The amounts that have been used without toxicity problems occur are:

Chromium Picolinate: 200-600 mcg / day

Vanadium Sulfate: not exceed 15 mg / day

Alpha-lipoic acid: 400-600 mg / day

Thermogenic supplements

Thermogenic supplements include an ample amount of substances that increase the metabolism. Basically there are those that increase spending and increasing metabolic rate, body temperature in order to reduce fat.

The most nown thermogenic activators of the adrenergic system are affecting lipid oxidation and increase alertness. The thermogenic like caffeine, stimulates the sympathetic nervous system-adrenal hormones and their major as epinephrine and norepinephrine, which is why athletes nervous nature should not take these supplements, not even coffee. The thermogenic ephedrine that do not cause an overstimulation of the nervous system but are effective for accelerating the reduction of fat.

The effects of the thermogenic can be summarized as follows:

  • Reduce the accumulation of fat by increasing metabolic rate through thermogenesis and activation of lipolysis
  • Increase energy acts as a tonic. Muscle metabolic processes intensify, increasing ATP generation by increasing substrate supply to the muscle
  • Usually athletes who tolerate coffee also do so with most thermogenics. Some supplements include the amino acid L-Tyrosine in its formulation it acts as a precursor for the biosynthesis of catecholamines and thyroid hormones and ensures the proper functioning of the sympathetic-adrenal system

The thermogenic and most used active substances are:

  • Guarana (caffeine)
  • Ma-huang (ephedrine)
  • Citrus aurantium (synephrine)
  • Green tea (theophylline)
  • Yohimbe (yohimbine)
  • L-tyrosine (tyrosine)
  • L-phenylalanine (Phe)
  • MCT (MCT)
  • Sida Cordifolia (vasicine)
  • Cayenne (Capsaicin)

Remember that some of these plants contain alkaloids that certain amounts may be positive in a doping test, in fact the ma-huang is banned because it contains ephedrine. Some thermogenics can increase excitability in predisposed or nervous, as usual it is essential to consult a professional if in doubt.

Inhibitors of lipogenesis

The best known inhibitor of lipogenesis is hydroxycitric acid or HCA from the fruit of the Garcinia cambogia, a plant used for seasoning food in parts of Asia.

The HCA is interesting for its ability to reduce fat synthesis. The carbohydrates we eat are stored as glycogen are converted into fat in the liver by the enzyme ATP-citrate lyase, HCA partially blocks this enzyme.

The effect can be expected is that lipogenesis or fat production is diminished and increases the ability to store more glycogen.

The HCA has been scientifically studied and appears to be a good ally in fat loss because it reduces the formation of fat, gives a feeling of satiety, improves glycogen stores resulting in more energy for muscle contraction and has no side-effects.

The HCA is a supplement that does not affect the nervous, you should know that the effective dosages are 500 mg. two or three times a day. It is much more effective if taken before meals with water and have a continuing effect is due to a pattern of about 7 or 8 days every 3 weeks. HCA combine with any insulin enhancer is a good idea to add effectiveness to the product.

Pyruvate and dihydroxyacetone

Pyruvate and dihydroxyacetone are two metabolites derived from the metabolism of carbohydrates.

The administration of pyruvate and DHA has been studied by a group headed by Dr. Stanko, they say we can expect the results of supplementation are:

  • Increased metabolic rate
  • Decreased body fat and improving blood lipid profile
  • An antioxidant, is an excellent sensor of hydrogen peroxide
  • There seems to be an increase in aerobic endurance possibly due to muscle glycogen sparing
  • Pyruvate and DHA are supplements that although they require a greater number of scientific studies with athletes, have a potential use as an ergogenic supplement fat reducer

Supplementation with DHA and pyruvate no, it seems, no effect of nervous system activation but instead were observed at high doses some gastrointestinal upset.
