The Claim
In healthy adult males, cortisol levels following a high-fat mixed meal reach a nadir at 4 hours and remain below baseline for up to 6 hours, whereas following a pure fat meal, cortisol levels reach a nadir at 2 hours and remain suppressed throughout the entire 6-hour postprandial period, demonstrating distinct temporal patterns of cortisol suppression depending on meal composition.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
After eating a meal with both fat and other nutrients, cortisol levels in healthy men drop to their lowest point at 4 hours and stay low for 6 hours. After eating a meal with only fat, cortisol drops faster—to its lowest point at 2 hours—and stays low for the full 6 hours. The timing and duration of cortisol suppression differ based on the type of fat-containing meal consumed.
See the scientific wording
In healthy adult males, cortisol levels after a high-fat mixed meal decline to a nadir at 4 hours and remain below baseline for up to 6 hours, while after a pure fat meal, cortisol declines to a nadir at 2 hours and remains suppressed throughout the 6-hour postprandial period, indicating distinct temporal patterns of cortisol suppression following different fat-containing meals.
What the research says
1 studyAfter eating a meal with lots of fat and other foods, cortisol (a stress hormone) drops the most at 4 hours and stays low for 6 hours. After eating just fat, it drops the most at 2 hours and stays low too. This study found exactly that.
