The Claim
In healthy adult males, postprandial cortisol levels peak at 0.5 hours following a glucose meal and decline below baseline by 3 hours, whereas after protein and fructose meals, cortisol levels decline continuously over the 3–6 hour postprandial period, indicating distinct cortisol response patterns between carbohydrate and non-fat macronutrient meals compared to fat.
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 different types of meals, healthy adult men show different patterns in cortisol levels over time: glucose causes a temporary rise followed by a drop below normal, while protein and fructose cause a steady decline over several hours, suggesting that the type of nutrient affects cortisol dynamics differently.

In healthy adult males, cortisol levels after a glucose meal peak at 0.5 hours and decline below baseline by 3 hours, while after protein and fructose meals, cortisol levels continuously decline throughout the 3–6 hour postprandial period, indicating that carbohydrate and non-fat macronutrients elicit distinct cortisol responses compared to fat.
What the research says
1 studyAfter eating sugar, cortisol (a stress hormone) spikes quickly then drops below normal by 3 hours. After eating protein or fruit sugar, it just keeps going down. But after eating fat, it dips then rises again — showing that fat affects cortisol differently than sugar or protein.
