Clinical Trial Summary

the study sought to investigate the influence of 8 weeks of a very low carbohydrate ketogenic diet on body composition, muscle strength, muscle area and blood parameters in competitive natural body builders.

Description:

nineteen natural body builders were randomly assigned to a ketogenic diet (KD) group or to a normal diet group (ND) with a traditional meal pattern. The two diets were isocaloric and included the same amount of protein per kg of body weight; but differed in the distribution of fats and carbohydrates; the latter were kept below 5% daily (less than 50g/day) in the KD group while represented 55% of the caloric intake in the WD group During the experimental period, training loads were similar in the two groups. Athletes were tested before and after 8 weeks of the intervention. Body composition , basal metabolism, muscle strength and blood parameters were measured.
