When healthy young men only eat between noon and 8pm for five days straight, it doesn't change how many calories they burn in a full day
Scientific Claim
Five days of time-restricted feeding (12:00-20:00 eating window) does not significantly affect 24-hour energy expenditure 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 energy expenditure. The study design can establish no effect for this specific outcome in this specific population.
Source Excerpt
“The 24-h energy expenditure, resting energy expenditure, fasting carbohydrate and the concentrations of TG, blood glucose, insulin, free fatty acids, and glycerol between the two trials were not significantly different (p > 0.05) (Table 2).”
Evidence from Studies
Supporting Evidence (1)
The study measured 24-hour energy expenditure in 8 healthy young males. The TRF group showed 2541.5±1406.2 kcal vs 2388.6±1370.4 kcal in the control group (p=0.419), indicating no significant difference. This is a direct measurement from the study's data table.
