Introduction: Strength sports are usually based on gaining the greatest possible strength or muscle mass, and for this purpose, appropriate training and specific nutrition are used.

Material and Methods: A total of 90 people took part in the study on the quantity and quality of calories consumed, and the final analysis included 60 people divided into 4 groups - 3 groups of athletes and a control group.

Results: Regarding the daily fat intake expressed in grams, there was a statistically significant main effect between the groups with the bodybuilders consuming less fat than the control group and weightlifters. Bodybuilders consumed more of this substrate than the other groups. In terms of calorific value of daily fat consumed, an intergroup main effect was observed, with bodybuilders consuming less fat than the control group and weightlifters. Bodybuilders consume significantly more protein per day than the other groups, and powerlifters more than powerlifters. In terms of daily fat and carbohydrates expressed as a percentage of the calorific value of the diet, significant main intergroup effects were observed, and bodybuilders consumed as much less fat as carbohydrates than the other groups.

Conclusions: The obtained results were subjected to statistical analysis and it was found that the composition of the diets used in the studied groups differed significantly and differed most from the rest of the bodybuilders, mainly in terms of higher protein and low fat consumption, as well as higher caloric content of the daily diet, with similar carbohydrate consumption in all groups being watched.
