8-Hour TRE Does Not Lower MyoPS

·1 hr 13 min·5 clips

The study found no difference in muscle protein synthesis between 8-hour and 12-hour eating windows.

The episode begins with host Carl Lanore introducing the topic of time-restricted eating and its potential impact on muscle protein synthesis. He shares his personal history with frequent eating as a powerlifter. Guest Dr. Evelyn Parr from Australian Catholic University explains her research focus on metabolic health, obesity, and prediabetes. She details the study design: men with BMI over 25 were given eucaloric diets with 1g protein/kg body weight, comparing 8-hour versus 12-hour eating windows over 10 days. The study used deuterated water methodology to measure muscle protein synthesis. Results showed no significant difference between groups, suggesting time-restricted eating doesn't blunt muscle synthesis when protein intake is adequate. The discussion covers limitations like only including men and measuring only fasting insulin. Lanore and Parr debate the causes of obesity and type 2 diabetes, with Lanore emphasizing personal responsibility and Parr highlighting genetic and environmental factors. They discuss the body positivity movement and whether obesity can be healthy. Parr notes that metabolically healthy obesity exists but may be an outlier. Lanore shares his personal transformation from 330 pounds with heart issues to his current health through diet, exercise, and sleep changes. The conversation touches on societal changes reducing physical activity, the importance of post-meal movement, and sleep quality. They briefly mention ketones and autophagy. The episode concludes with plans for future research and thanks to sponsors.

As heard by us

An 8:16 fasting window gets a careful look at muscle protein synthesis.

Super Human Radio spends this hour on time-restricted eating and the familiar bodybuilding concern that a tighter eating window might compromise muscle.
