How do weight loss supplements work: increased thermogenesis

Most commonly available weight loss supplements work by stimulating the process of thermogenesis, which is responsible for increasing heat production. Raising the temperature of the cells in the body increases the metabolic rate, which simultaneously promotes the reduction of accumulated fat tissue. Such substances used before a planned workout (e.g. strength and endurance workout) often lead to intensification of the sweating process - this creates ideal conditions for burning excess fat and effectively shaping a slim body. Natural thermogenics consist mainly of plant extracts, which should be standardised:

• bitter orange → synephrine
• cayenne pepper → capsaicin
• black pepper → piperine
• ginger → gingerols

How do weight loss supplements work: lipolysis

Lipolysis is a reaction that literally breaks down fat tissue. An example of a weight loss supplement that works in this way is a product containing L-carnitine. This substance is an amino acid which acts on free triglycerides and fat deposits. The purpose of L-carnitine is to increase the transport of fat molecules to the place where they are burnt (oxidised), i.e. the mitochondria. These are small parts of cells that convert supplied fat into energy - the body gains additional energy reserves to be used for e.g. more intensive exercise.

How do weight loss supplements work: reduction of fatigue

People undergoing weight loss repeatedly have to deal with the problem of excessive fatigue levels and insufficient energy. This is usually caused by a combination of high-intensity exercise with a gradually increasing calorie deficit in the daily diet. Therefore, supplements should support the body in maintaining a correct energy metabolism and stimulating the work of the nervous and muscular systems. What's more, products designed for people who are losing weight often contain ingredients to help increase the body's adaptation to increasing feelings of exhaustion. Which ingredients should be included in a fat burner? The presence of magnesium, B vitamins, caffeine and plant extracts (e.g. guarana, green coffee and tea, cocoa beans) will certainly prove useful.

How do weight loss supplements work: combating oxidative stress

It should not be forgotten that during weight loss, it is necessary to ensure that the body's immunity works properly. Protection of cells against the adverse effects of oxidative stress and free oxygen radicals is possible thanks to vitamin C, quercetin and the already mentioned green tea extract.
