Conditions
Brief summary
The purpose of this study is to investigate the effects of 4 weeks of carbohydrate deprivation (through a ketogenic diet) on hypertrophy signalling after a single bout of exercise in healthy trained male subjects, and the impact on body composition, muscle strength, and blood parameters.
Interventions
All participants perform a four-day resistance training aimed to stimulate a hypertrophic response.
Subjects allocated to the ketogenic diet arm (KD group) consume less than 50 g of carbohydrates per day.
Subjects allocated to the western diet arm (WD group) consume a standard diet based on 55% of their daily calories from carbohydrates.
