How Does Weight Loss Supplements Work?

Anyone who wants or needs to lose weight can follow different strategies to help the body eliminate extra fat, and using weight loss supplements can be an ally. However, many believe in products that promise to “dry” miraculously or that consuming them is enough for weight loss.

After All, Do Weight Loss Supplements Work?

Let’s start our conversation with an essential premise: no supplement alone loses weight. Weight loss supplements are made with nutrients that help different processes in our body that favor weight loss. 

Added to this, the ideal is to always consume them with the guidance of a doctor or nutritionist, in addition to combining consumption with a caloric deficit and other habits, such as the practice of physical activity, leaving behind only the extra kilos, not the weight. Health. 

How Do Supplements Help With Weight Loss?

Our body is perfect! It needs body fat for many functions, such as energy, insulating the body, and protecting vital organs.

Therefore, it is worth remembering that fat is an essential macronutrient for the body to function in balance. 

When fat is accumulated excessively, in addition to causing weight gain, it may be related to inflammatory processes and other clinical conditions, such as metabolic syndrome, which goes hand in hand with chronic diseases. Thus, attention to weight management is not limited to body aesthetics but is also necessary for health and well-being. 

Therefore, it is essential to remember that weight loss supplements have ingredients that help specific processes that can result in weight loss. Learn how the most well-known mechanisms work:


Thermogenesis is the body’s natural process of producing heat by burning calories. It is fundamental for homeostasis, as it regulates our internal temperature. For example, when we feel cold, metabolic processes take place to maintain adequate body temperature. 

The big draw is that fat burning is one of the sources of thermogenesis, which can be stimulated by nutrition. Therefore, weight loss supplements made with ingredients with thermogenic action can be associated with the diet of those who want to lose weight.


Our body uses glucose, a simple carbohydrate, as an energy source. But when this nutrient is not available, it resorts to fat sources. For this, the liver modifies fat molecules into ketone bodies, transforming fat into an energy source, which favors weight loss. 

This is why the ketogenic and low-carb diets are chosen by many people who want to lose weight, and supplements made with good fats and restricted in carbohydrates also help in this process.


Eating little and feeling satisfied is one of the wishes of those who want to lose weight. However, it is essential to know that many factors contribute to the body “perceiving” that we are full. 

It all starts when the food arrives in the stomach. The food bolus promotes distension by “filling” the organ. When this happens, there is communication between the nerves in the stomach wall and the hypothalamus, an area of ​​the brain that controls hunger. This communication helps us feel full.

Additionally, satiety also relies on the action of hormones related to the endocrine and digestive system, such as leptin, which is released from fat molecules and acts in the brain, more precisely, in appetite regulation.

Still, there are foods that, when passing through the stomach and intestine, have a slower energy release, such as fiber and some complex carbohydrates. Therefore, the more calmly we eat and ingest nutrients with sustained release; we may signal to the body that we are satisfied for a more extended period, boosting the feeling of satiety, which makes hunger not appear so quickly.

Have you noticed how many vital factors promote satiety, and none are related to overeating? Our body is brilliant and has mechanisms that favor health and ideal weight when they are in balance and receive the necessary nutrients.

Energy Metabolism

Energy metabolism is the set of energy-related chemical reactions that take place in our body so that it has the fuel to function. By accelerating metabolism, the body increases caloric expenditure, stimulating the use of nutrients that serve as energy sources, such as fat. Therefore, “giving a hand” to metabolism is also an alternative for those who want to lose weight.

It is worth noting that thermogenesis and the ketosis process are mechanisms that use energy metabolism as a strategy to make the bodywork and expend energy.
