Using fitness supplements is a common practice among fitness enthusiasts and bodybuilders. And, among all those workout supplements, fitness protein supplements, commonly marketed in the form of shakes, are the most prevalent ones. However, according to some researchers, there is a gap between this practice and scientific proof. That, until now when scientists examined the effects of protein shakes on fitness enthusiasts’ bodies. Accordingly, fitness protein supplements might build fat mass, along with muscle.
The majority of protein supplements use a specific blend of high-quality proteins, amino acids, electrolytes, and carbohydrates, and are sold usually right inside gyms, at pharmacies, health stores, or at specialized nutrition stores. Now, some researchers from France and Tunisia published a study in the Science and Sports journal where they debate the real effects of fitness protein supplements on the muscle and fat mass, saying that until now there was a significant gap between science and practice in the field of fitness supplements.
Fitness Protein Supplements Might Also Build Fat Mass, Along With Muscle
“We, therefore, do not yet know whether men practicing resistance training in gyms truly benefit from using protein and carbohydrate shakes that they self-prescribe,” the scientists said. To find out more, they examined two groups of fitness enthusiasts. The first group was always finishing the training session with a protein shake, while the second group opted for no after-workout supplementation.
After eight weeks, during which the two groups followed a similar training routine, the researchers came in and measured the groups’ representants muscle and fat mass. The first group, the one who always consumed fitness protein supplements after workouts, presented larger muscle mass but also more fat mass in comparison to the second group who, even though showed increased muscle mass, revealed a depreciation in the fat mass.
“Our results indicate a major body mass gain in the group consuming supplements. However, the analysis of body composition revealed that a gain of body fat was responsible for this significant difference. The group consuming supplements gained fat mass while the group who didn’t consume supplements lost fat mass,” the researchers concluded.
