Causes of Underweight

It has been proven that obesity or excess thinness may cause various kinds of diseases. Therefore, you should always strive to maintain your proper weight. Both obesity and underweight are related to different causes, and you should change your diet and daily routine to remedy this situation.

If you want to gain weight, you should remember that the number of calories you consume with food should be higher than your body's daily energy expenditure. It is recommended to use brewer's yeast to normalize the metabolism and gain weight. In this article, we are going to discuss the benefits and effectiveness of this supplement.

Meanwhile, before we talk about the ways to treat thinness, we need to understand its causes. Let’s consider the most common of them:

  1. Congenital thinness (typical asthenic physique).
  2. The presence of cortisol in the body – a stress hormone that is produced in the body during periods of stressful situations. It is also called the death hormone. Its excess production contributes to the destruction of muscle tissue and formation of excess fat (as a defensive reaction to stress).
  3. Gastrointestinal tract disorders.
  4. Metabolic disorder.
  5. Abnormal functioning of the thyroid gland.
  6. Dietary disorders (malnutrition, irregular diet, consuming low-calorie food).
  7. excess physical or mental activity during the day.
  8. The presence of parasites in the body.
  9. The use of stimulants such as amphetamine.
To find out the exact cause, you need to see a doctor. Remember that only a specialist can make a final diagnosis and prescribe the right course of treatment for you.

Some Facts about the Supplement

Brewer's yeast is a unicellular fungus (Saccharomyces cerevisiae) that is a good source of protein, minerals, micronutrient elements, and other useful substances. In medicine, it is classified as a dietary supplement. The action of this supplement consists in the involvement and active participation in the metabolic process.

Brewer’s yeast supplies the body with the missing nutrients, normalizes the functioning of the digestive system, and increases appetite, thus improving the diet and helping the person gain the missing body weight. Besides, the supplement contains quite a lot of calories – about 450 kcal per 100 g of dry yeast.

Protein, the building material of the body, makes about half of the composition of brewer's yeast. It is easily absorbed.

More about the Composition

In addition to the above-mentioned protein, brewer's yeast contains:

Various carbohydrates About 13 g per 100 g of product

How to Take Brewer’s Yeast?

Depending on the kind of the product and the place where you have purchased it, its use may differ. If you have bought yeast at a pharmacy, an instruction with indication of the time for use, frequency, and dosage should be attached to the packaging.

It should be noted that most experts recommend taking the supplement after eating.

If you have taken yeast from a brewery, for example, the dosage may be as follows: dissolve two teaspoons (for adults) or one teaspoon (for children) in a half glass of water. The duration of the full course of treatment should be no more than 1–2 months.

If you use brewer's yeast for disease prevention, the course should last about 1 month. After completing the course, you should take a 23 month break, after which you can resume taking the supplement.

Common Myths

  1. Many people question this weight gain method because of the risk of getting excess weight along with gaining the missing body weight. However, it should be noted that the supplement we are talking about is aimed exclusively at improving the metabolism. Yes, it means increasing the appetite, but to healthy and necessary limits.
  2. Another popular fallacy is that brewer's yeast is used in the preparation of a well-known drink – beer. However, this is just a myth which is possibly associated with the name of the product. This ingredient is not included into the beer’s composition, because it is completely removed in the filtering process.


Thus, brewer's yeast can be used to gain the missing body weight. But you should take into account some things:

  • Before you start taking the supplement, you need to properly determine the cause of underweight.
  • Brewer's yeast is a single-celled fungus that has universal properties and promotes not only the normalization of metabolic processes, but also the elimination of many other health problems.
  • As a rule, this method is recommended to treat digestive diseases, avitaminosis, depressions, and other disorders. It is contraindicated in case of kidney failure, gout, anemia.
  • This supplement can be purchased not only in a pharmacy and it can be prepared in various ways.
  • Before you begin the treatment course, you should consult a doctor.
