Metabolism pills are a very different series of products that promise to improve body composition by eliminating stored fat or preventing the creation of new deposits. Their effects on metabolism are not yet well known; therefore, it is necessary to act wisely during supplementation.

What Are Metabolism Pills, and How Do They Work?

Metabolism pills are supplements or food supplements that are used to stimulate body weight loss. In general, this effect is achieved through an increase in energy expenditure, which will require greater destruction of the stored lipids to produce energy. This is precisely why they are called “fat burners.”
Inside fat burners, it is also possible to find food supplements that block the absorption of food lipids.

Are Metabolism Pills Really Effective?

It is useless to find a reliable and easy-to-use fat burning supplement if its effects are not satisfactory. In the following lines, you will find a summary of the latest information on fat burners that have passed our safety criteria, with references to the most recent studies.

Chlorogenic Acid (green Coffee)

Chlorogenic acid is a polyphenol with antioxidant and anti-inflammatory activity. In animals, this compound is able to reduce the fatty tissue accumulated in the body, contributing to weight loss. However, it has not been established whether this fat loss results in tangible results in humans.

Caffeine

The activating effect of caffeine has been shown to accelerate the metabolism of the human body in the short term. In the long run, however, tolerance to the effects of this molecule is produced, and its fat burning effect is lost.

Forskolin

Forskolin is a compound found in a mint-related plant (Coleus forskohlii). In the form of supplements, forskolin has proven useful in reducing the fat mass of obese rats. Even in a study with obese men, this product was able to achieve significant weight loss.

Fucoxanthin

Fucoxanthin is obtained from the Undaria pinnatifida algae. Human studies have shown that this compound is capable of promoting weight loss and oxidation of fat mass in humans, although the clinical studies available so far may be subject to various conflicts of interest.

L-carnitine

L-carnitine acts as a fat transporter to the mitochondria (responsible for body energy production); therefore, it is essential to maintain adequate levels of this substance to use lipids as fuel. Its effectiveness decreases in people who already have adequate carnitine levels.

Panax Ginseng

The root extract of this millennial plant has a high fat burning power in studies on obese rats. Human studies show that ginseng supplementation has a slight slimming effect, which combines with other benefits (such as a strengthening of the intestinal microbiota).

Taurine

In a 2010 study, a taurine supplement was given to professional cyclists, hoping to find an increase in their physical performance. Although no improvement in the athletic parameters of these subjects was found, a significant increase in fat oxidation was observed.

Yohimbine

There are two studies (conducted respectively in 1991 and 2002), relating to yohimbine (from the bark of the African tree Pausinystalia Yohimbe), which demonstrate an increase in weight loss in the elderly on a low-calorie diet. Unfortunately, this effect was not reproduced in subsequent experiments.

Most fat burners are capable of promoting weight loss in animals. However, human experiments have been conducted on a small number of individuals who need further studies before they can ratify their effects. Caffeine is the exception, being clearly able to speed up your metabolism (for a short period of time).

How to Take a Fat Burner to Get the Most out Of It?

It is necessary to demonstrate that the effects of fat burners depend, to a greater or lesser extent, on the degree of physical activity. The best way to increase basal metabolic expenditure (amount of calories consumed by our body at rest) is through sport. They will not be useful in combination with a sedentary lifestyle.

In addition, a series of healthy lifestyles will help increase the chances of success of our fat burning supplement, also avoiding the appearance of the dreaded “rebound effect” (recovery of the weight lost when the use of the fat burning product is abandoned). You will find them described in the following list:

Follow a Healthy Diet

A diet low in simple carbohydrates (but which provides enough protein, good fats, vitamins, and minerals) will contribute to weight loss. Furthermore, reducing the intake of ‘bad’ fats prevents the onset of gastrointestinal adverse effects from supplements such as forskolin.

Drink

The most stimulating fat burners, such as caffeine, cause an increase in body temperature and sweating. The contribution of water (also in the form of soups, infusions, or drinks) will be very important to avoid the appearance of dehydration.

Stay away from alcohol and drugs

Since many fat burning supplements require liver function metabolism, it is not recommended to combine them with alcohol, which also depends on this organ for proper elimination. Some exciting drugs, such as amphetamines, could potentiate the effects of fat burners with potentially lethal effects.

What Precautions Should I Take While Taking a Metabolism Pills?

Supplementation with a fat burner should be considered fundamentally different from that performed with any other food supplement. The use of a fat burner should be limited in time (until the desired amount of weight is lost), and its use is not recommended for people with weight within the normal parameters.

Can I Use Fat Burners if I Suffer from Chronic Conditions?

People with cardiac, hypertensive, diabetic, renal, metabolic, neurological, psychiatric, or muscular conditions should refrain from using fat burners without the prior approval of a doctor.

Can my drugs interact with fat burners?

Surely! Unfortunately, fat burners can affect drugs, decrease their effects, or generate dangerous reactions. Although each of these products can interact with different drugs, the main substances involved will be :

• Anticoagulants
• Antidiabetic
• Psychiatric drugs
• Antihypertensive
• Antithyroid
• Thyroid hormones
• Contraceptives

Can Children Take Fat Burners?

The safety of fat burning supplements in children who have such a vulnerable metabolism has not been studied. For this reason, it is recommended not to administer fat burning supplements under the age of 18.

Pregnant or Breastfeeding Women

The influence of fat burners on the fetus or their presence in breast milk has not been studied, although there is evidence that these supplements could adversely affect the growth of the baby. Therefore, its use is not recommended.

In conclusion, the people who can make safer use of fat burning supplements will be those who are healthy, in good general condition, and who do not take drugs for chronic diseases. Otherwise, it is advisable to consult a doctor before starting to use a new fat burner.

Purchase Criteria

The real challenge of fat burners is that of deciding when to buy them. You won’t find hundreds, but thousands of items that will promise you to “dissolve” unwanted fat from your body at a very low price. Do not be fooled by empty promises and read our purchase criteria before entrusting your health to an unknown manufacturer.

Dietary Needs

Don’t lose sight of your dietary preferences, allergies, and intolerances. If you are celiac, make sure your fat-burning product is labeled “gluten-free.” If you are vegan, take a plant-based supplement, for example, based on ginseng or caffeine. Pay attention to the capsules of these supplements, which can be made of animal jelly.

Origin of The Product

Intoxication has been described during integration with forskolin and fucoxanthin secondary to the contaminating products contained in these articles. It is essential to avoid any type of toxic or pesticide in our fat burners; Choose organic farm products every time you look for a plant extract.

Sensitivity to Stimulants

Pay close attention to stimulant-based supplements, such as ginseng or caffeine. If you are a nervous or anxious person, these fat burners can worsen your condition and give you a very unpleasant experience. Know yourself, and if your personality is prone to discomfort, opt for other compounds, such as fucoxanthin.

It is necessary to highlight that while caffeine is considered quite safe in the recommended doses, its overdose can cause arrhythmias, hypertension, and even brain edema and death. Caffeine sensitive people can present this syndrome using standard doses, so they should refrain from using any fat burners with caffeine.

Combination of Ingredients

Remember that most of the side effects of fat burners (usually a fulminant liver failure, kidney failure, or cardiovascular disease) have appeared after using supplements containing various combinations of fat burning elements. For safety, choose a supplement based on a single product and avoid mixing it with other ingredients.

Storage and Expiration

Follow the manufacturer’s instructions for storing the fat burning product. In general, these items should be kept in a cool, dry place away from sunlight. Do not use expired products, which will have lost their fat burning potential (and could have unpleasant effects).

Value for Money

The price of fat burners will depend on their active ingredient. Taurine and caffeine will stand out for their low price and high value, while the exclusive fucoxanthin has a price given by innovation and its promising potential.

Conclusions

How difficult it is to reach our ideal weight! Unfortunately, healthy nutrition and an active lifestyle are always needed. However, if you need further help, you can look for a good fat burning supplement. These products should not be taken lightly; if they are not used wisely, they could have harmful effects.
