30 Seconds Summary
The “Leangains” Intermittent Fasting Study Is Finally Here

  • Intermittent fasting, also known as time-restricted feeding, has historical roots in seasonal food availability and religious practices, with modern popularity among athletes rising around 2010.
  • Martin Berkhan's 'Leangains' approach to intermittent fasting involves an 8-hour eating window and a 16-hour fasting period, focusing on high protein intake and varying calorie consumption based on workout days.
  • A recent study on intermittent fasting involved participants who were experienced lifters, comparing those who ate within an 8-hour window to those with regular meal times over 8 weeks.
  • The study found that the intermittent fasting group lost a small amount of fat likely due to a slight calorie deficit but showed no significant differences in muscle mass or strength compared to the normal diet group.
  • Blood work changes in the intermittent fasting group suggested possible health benefits like improved metabolic health, but these findings need further research for broader applications.
  • The study was limited by its short duration, the homogeneity of participants (healthy, young males), and the reliance on dietary recall for nutrition data.
  • Although intermittent fasting was shown to be non-harmful and possibly beneficial for active individuals, it's not a magical solution for weight loss or muscle gain compared to traditional eating patterns.
