Unpleasant statistics — in the world almost 2 billion adults are overweight, of which 600 million suffer from obesity. The question «How to Lose Weight?» is among the top lists of all Internet search engines. Any diet doctor will answer that the most effective way to combat obesity is proper nutrition and exercise. This is a long process that requires persistence and willpower.
But, admit it, how you want everything and quickly! Especially if there is a month left before vacation. Especially if happiness in your personal life is at stake! Here pharmaceuticals come to the rescue. The leader in the production of weight loss products is «the fattest country in the world» – America. Diet pills from the USA are actively advertised and distributed in Russia. Let’s try to figure out how effective they are.
Types
In any pharmacy, at least one stand is dedicated to weight correctors. Their names are the most diverse, and the advertisement is tempting. All means can be divided into several groups.
Appetite-affecting
Taking such pills, the patient feels full. This is a kind of deception of the body by stimulating the release of catecholamines (adrenaline, noradrenaline, serotonin, dopamine). Such active intervention in the hormonal regulation of metabolism should not be prolonged. Otherwise, there will be a depletion of the nervous system and the adrenal cortex, which produce these hormones.

For example, hoodia extract (a type of cactus) contains a steroid glycoside that acts on the centers of the brain (in the hypothalamus) responsible for the feeling of hunger. The body «thinks» that it has already eaten, appetite decreases.
Another way to reduce appetite is to fill the stomach and intestines with products that have no nutritional value and are a mechanical stimulant of satiety. This is how many fibers that swell in the digestive tract «work», which are excreted from the body unchanged.
Diuretics
Many American diet pills contain diuretic herbal preparations. They do not affect fat cells, but reduce weight by removing excess fluid. This is important for obesity, which is accompanied by hidden and overt edema.
It must be remembered that mineral salts are «washed out» together with the liquid. Therefore, when using such drugs, it is necessary to additionally take vitamin and mineral complexes.
Metabolism Stimulators
There are effective remedies that can speed up metabolic processes in the body. Such drugs are called «fat burners». But this term contains a fundamental error.
Many substances belonging to this group (for example, the famous l-carnitine) do not break down fats, but contribute to their transport to mitochondria (the main energy stations of the cell). There fats are converted only under the condition of aerobic exercise.
Simply put, if a person lies on the couch and drinks diet pills, nothing happens. If you use such drugs during exercise (running, fitness, swimming, etc.), weight decreases at an accelerated pace.
Calorie Blockers
They act in the digestive tract, preventing the absorption of fats and carbohydrates. As a result, most of the food is not digested, but passes through the intestines in transit. White bean extract and chitosan have such properties.
A brief overview of medications
Modern weight loss products manufactured in the USA are created taking into account the complex action in all areas of weight loss. Here are the most popular ones.
Green light
Composition: pectin, guarana, fucus, hoodia, orange peel extracts, l-carnitine, raspberry, chitosan, coleus forskohlii extract. The ability to adjust weight mainly depends on caffeine and l-carnitine.
Effects:
- reduces the absorption of fats in the intestines, due to chitosan and pectin;
- Fucus blocks pancreatic amylase – an enzyme responsible for the breakdown of carbohydrates in the intestine, as a result of which they are excreted from the body in transit;
- accelerates fat metabolism with the breakdown of excess lipids (responsible for caffeine contained in guarana extract, orange peel, raspberries);
- diuretic effect is provided by caffeine;
- hoodia extract reduces appetite;
- l-carnitine stimulates the breakdown of fats in cells during exercise.
Important! Green light tablets may be contraindicated in people with heart and blood vessel diseases, as they contain natural sources of caffeine.
Phen375
Their composition is similar to the previous ones. Contains l-carnitine, orange peel extract, caffeine. Additionally include:
- Calcium carbonate is a trace element necessary for the normal structure of bones.
- chromium picolinate – reduces cholesterol levels, which is especially important for people with severe forms of obesity;
- cayenne pepper – accelerates the process of heat production in the body, due to which fats and carbohydrates are additionally broken down.
The drug is quite balanced and solves the problems that often accompany excess weight (increased cholesterol levels, leaching of minerals, including calcium). But, before you start taking this remedy, it is better to consult a doctor.
Skinny Fiber
In composition, these tablets are fundamentally different from the previous ones:
- Glucomannan fiber, which is contained in the tubers of the plant, increases in volume when it enters the stomach and quickly «satisfies hunger» mechanically.
- The extract of an exotic tree from Brazil contains caffeine, potassium and allantoin. We are already familiar with the effects of caffeine. Allantoin has proteolytic properties (breaks down proteins), and potassium replenishes the deficiency of minerals.
- Karaluma cactus extract reduces appetite, breaks down fats, and lowers blood sugar levels.
- Bromelain is an enzyme found in kiwi, papaya, pineapple. For weight loss, its ability to break down and quickly absorb proteins is important. This enzyme normalizes the intestinal microflora, which also has a beneficial effect on metabolism.
- Papain is an enzyme that breaks down proteins, fats, carbohydrates. Additionally, it has a diuretic effect. Enhances intestinal peristalsis and elimination of toxins from the body. It has a beneficial effect on the skin, hair, nails.
- The enzymes lipase and peptidase are also necessary for the normal digestion of food, which suffers from obesity.
The developers of the Skinny product paid more attention to normalizing metabolism, and not just removing excess fat from the body. This is of fundamental importance, since it is more important to correct the cause of obesity, and not to fight its consequences.
Lipodrene
A whole line of drugs based on the alkaloid ephedrine. The tool is actively used in sports medicine. Lipodrene accelerates all types of metabolism, reduces appetite, and enhances heat production. Ephedrine also has psychotropic properties – it improves mental and physical performance (in therapeutic doses).
