Time-Restricted Bulking: Can a Narrow Eating Window Build Muscle Without Excess Fat?

Coach Phil Stevens, Dr. Mike T. Nelson, and Dr. Lonnie Lowery examine a new 12-week randomized controlled trial of 16:8 time-restricted eating during a bulking phase. They discuss the study's modest sample, single-frequency BIA, prescribed versus actual calorie and protein intake, and similar fat-free-mass and strength gains despite the restricted group eating less than planned. The conversation challenges the idea that a 300–500 calorie surplus is universally sufficient, considers beginner gains versus results in experienced lifters, and explores practical factors such as adaptive metabolism, training age, sleep, stress, stimulants, DOMS, and the difficulty of accurately tracking food in free-living conditions.
