How Do Fat Burners Work?

Fat burners are diet pills that contain natural or artificial fat-burning ingredients. These fat burners help in burning fat. These supplements boost our metabolism and also help to burn calories. 

These diet pills increase energy expenditure or fat metabolism, diminish fat absorption, and increase fat loss by fat oxidation during physical exercise. They somehow cause long-term alterations that support fat metabolism[4]

These supplements come in two forms like those containing stimulants and stimulant-free fat burners. Many fat burners come with various combinations of ingredients, and each of them has its specific mechanism of action in fat loss. Some of the popular ingredients, such as caffeine and green tea, have evidence to back up their role in inducing fat metabolism. 

The ingredients in fat burners such as caffeine, green tea extract, conjugated linoleic acid, and chromium may increase your metabolic rate. Metabolic rate is nothing but the number of calories one burns at a given time.  

Many of these fat burners contain soluble fibers such as glucomannan[5], beta-glucans, and guar gum which are known to promote a feeling of fullness and prevent you from consuming more calories. These fibers work as appetite suppressants. Apart from this, fat burners also reduce the amount of fat absorption but block fat production. They also inhibit the production of new fat cells.  

Fat-Burning Supplement

These fat-burning supplements also induce thermogenesis. These thermogenic ingredients[6] boost the metabolism and increase the amount of fat burnt. Fat burners can also work as appetite suppressants. Thermogenic means heat-producing. When the body burns calories, it produces more heat, so these supplements that boost metabolism are considered thermogenic. Some of the popular thermogenic ingredients include Capsaicin, Green tea extract, Garcinia cambioga, Yohimbine, and caffeine. 

These fat burner supplements contain a blend of  thermogenic ingredients. These blended supplements boost metabolism[7] even more when combined with physical activity. 

Furthermore, an Eight-week study[8] found that obese and overweight individuals who consumed these supplements containing Capsaicin, Caffeine, and Green tea extract lost an additional 0.0454 kg of body fat compared to the placebo group. 

What To Avoid in Female Fat Burners

The first and foremost thing to do while buying any supplements is to scan their ingredient list. These ingredients may interfere with medications and may worsen the condition. Additionally, dietary considerations are important if you are allergic to some ingredients. Vegetarians and vegans should check with the brand about animal products used in the supplements. For example, gelatin is not suitable for vegans. 

Apart from the ingredients and their effects, it is important to know the source of these ingredients. Although, it is a daunting task. Some resources can help you with that. Customer reviews are a great place to learn about the product and its side effects. Using too much or too many natural fat burners are also linked to acute liver failure[9].
