The Claim
In healthy young men, the ingestion of protein, fat, or water prior to exposure to psychosocial stress does not result in a statistically significant difference in cortisol response among the three conditions.
What the research says
Challenges is higher
Challenge is ahead, but a single strong supporting 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.
If you eat protein, fat, or just drink water before a stressful situation, your body’s stress hormone (cortisol) reacts about the same no matter what you ate or drank.
See the scientific wording
In healthy young men, ingestion of protein, fat, or water prior to psychosocial stress does not produce a significantly different cortisol response compared to each other.
What the research says
1 studyStudy: Glucose but not protein or fat load amplifies the cortisol response to psychosocial stress.
The study found that drinking water, eating protein, or eating fat all led to similar stress hormone levels, which matches the claim — but eating sugar made the stress hormone go up higher than the others.
