Cortisol, alpha amylase, blood pressure and heart rate responses to food intake in men aged 50–70 years: importance of adiposity

Conclusions While men with a moderate level of overweight/obesity had a significant HPA axis response (as measured by salivary cortisol) to a standardised lunch, lean men had no HPA axis response. Lean and overweight/obese men had similar increases in SAM system activity (as measured by salivary alpha amylase) in response to the meal.
