Effect of Ketogenic Diet on Muscle Hypertrophy
Study Details
Study Description
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.

---|---|
Experimental: ketogenic diet Participants will perform a single exercise bout after 4 weeks of resistance training combined with a ketogenic diet (KD group). |
Other: resistance training
All participants perform a four-day resistance training aimed to stimulate a hypertrophic response.
Other: ketogenic diet
Subjects allocated to the ketogenic diet arm (KD group) consume less than 50 g of carbohydrates per day.
|
Active Comparator: western diet Participants will perform a single exercise bout after 4 weeks of resistance training combined with a western diet (WD group). |
Other: resistance training
All participants perform a four-day resistance training aimed to stimulate a hypertrophic response.
Other: western diet
Subjects allocated to the western diet arm (WD group) consume a standard diet based on 55% of their daily calories from carbohydrates.

Outcome Measures
Primary Outcome Measures
- mammalian target of rapamycin (mTOR) signalling [Change from baseline to 4 weeks]
Measurement of the change in muscle protein anabolic signalling pathway in response to a single bout of resistance exercise by western blot analysis.
Secondary Outcome Measures
- Skeletal muscle mass [Change from baseline to 4 weeks]
Measurement of the change in kilograms of muscle mass via Dexa
