Macro partitioning
Short-term (10-day) time-restricted eating (8-hour window) does not impair daily myofibrillar protein synthesis rates compared to an extended 12-hour eating window when protein intake is matched.
If you are an overweight or obese male who exercises recreationally, switching to an 8-hour eating window (e.g., 10 AM to 6 PM) for 10 days will not hurt your muscle protein synthesis, provided you eat the same amount of protein (1g/kg) as you would over a longer period. Focus on hitting your daily protein goal rather than worrying about the clock.
Consuming food within an 8-hour time-restricted period does not lower daily MyoPS rates when compared with an isoenergetic diet consumed over 12 hours.
Why this rating
Randomized controlled trial with objective biochemical measures (D2O method), though sample size is small (n=18) and duration is short (10 days).
