How to lose fat with BCAAs?

When going on a diet, the priority is often to lose weight. To eliminate extra pounds, the strategy used is generally calorie restriction combined with physical activity such as cardio. If by doing this you can actually lose weight, the risk is that you will lose more muscle and lean mass than fat. The result: you will have lost weight on the scale, but in front of your mirror, your excess fat will not really have disappeared.

Why? To put it simply, if you reduce your calorie intake, there is a risk that your metabolism will change. Your body will therefore adapt by consuming less and storing more, which can paradoxically result in weight gain. If your energy intake is insufficient and on top of that you practice intense sporting activity, you will quickly find yourself in a "catabolic" state. Your muscle fibers will then be broken down to produce energy.

In order to avoid this disastrous situation during your workouts and to optimize your lean, BCAA supplementation is an excellent solution.

What are BCAAs?

BCAAs (Branched Chain Amino Acids) are essential amino acids: they cannot be synthesized by our own body, so they must be provided through food or supplementation.

BCAAs are essential in bodybuilding because they provide energy to the body to maintain the level of ATP (Adenosine Triphosphate) present in muscle fibers, allowing muscle contraction during exertion.


BCAAs also help resist fatigue better. During physical exertion, the level of Tryptophan entering the brain increases, triggering the formation of serotonin which increases physiological and psychological fatigue. An additional supply of BCAAs helps limit the entry of Tryptophan into the brain and therefore reduce fatigue. ⁠

BCAAs therefore improve your performance in training. In addition to that, they can also help you burn fat.

BCAAs help burnin fats

Taking BCAAs helps build muscle integrity and keep your metabolism at a high level. This will help you both maintain muscle mass and prevent fat gain.

Leucine, an amino acid found in BCAAs, specifically helps stimulate anabolism, increase energy expenditure and burn more fat. In fact, by taking BCAAs during training, the body will mobilize fat as a source of energy instead of drawing on the amino acid reserves present in the muscles.

⁠Researchers have been very interested in this link between BCAAs and fat loss. A recent study (1) has shown that BCAA supplementation in trained people performing resistance exercise and a low calorie diet helped maintain lean body mass, preserve muscle while reducing body fat.

In addition, the great advantage of BCAAs is that they specifically target abdominal fat, which is usually the one that you want to eliminate first.

How to use BCAAs properly? ⁠

⁠We advise you to take your BCAAs during your meals, in combination with foods rich in animal proteins or in your protein shaker. This will provide more amino acids in your body, improving your muscle rebuilding and recovery after a workout.

⁠We recommend that you take your BCAAs around training to increase your energy, decrease fatigue and better oxidize your fat. Our mix advice for supplementation during training: ⁠

- 10g of Nutrimuscle BCAAs

- 20g of Nutrimuscle Nutri-Fibers

- 20g of Nutrimuscle⁠ Peptopro

If you are under 35, we recommend that you take Nutrimuscle BCAAs Resistance (2 scoops of Leucine, 2 scoops of Valine, 1 scoop of Isoleucine) because the assimilation of Valine is less good when you are young. ⁠

⁠If you are over 35, we recommend that you take Nutrimuscle BCAAs Constructors (4 scoops of Leucine, 1 scoop of Valine, 1 scoop of Isoleucine) because the absorption of Leucine decreases from the age of 35.
