When healthy young men only eat between noon and 8pm for five days straight, their bodies burn fat much faster while they're fasting compared to when they eat throughout the day
Scientific Claim
Five days of time-restricted feeding (12:00-20:00 eating window) increases fasting fat oxidation rate by approximately 250% compared to a control feeding schedule (8:00-20:00) in healthy young adult males aged 22±1.3 years with BMI 26.0±0.38 kg/m²

Assessment Explanation
This is a randomized crossover RCT with direct measurement of fat oxidation rates. The study design can establish causation for this specific outcome in this specific population.

“The fasting fat oxidation rate of the time-restricted feeding trial was significantly higher than that of the control trial (p < 0.001)”
Evidence from Studies
Supporting Evidence (1)
The study directly measured fasting fat oxidation rates in 8 healthy young males during two different feeding schedules. The TRF group showed 0.14 g/min vs 0.04 g/min in the control group (p<0.001), representing a 250% increase. This is a direct measurement from the study's data table.
