When healthy young men only eat between noon and 8pm for five days straight, it doesn't change their baseline free fatty acid levels
Scientific Claim
Five days of time-restricted feeding (12:00-20:00 eating window) does not significantly affect fasting free fatty acid levels in healthy young adult males aged 22±1.3 years with BMI 26.0±0.38 kg/m²
Original Statement
“The fasting fat oxidation rate of the time-restricted feeding trial was significantly higher than that of the control trial (p < 0.001). 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).”
