Macronutrients stimulated a postprandial rise in circulating cortisol in lean, healthy men, according to researchers in the United Kingdom.

“These observations provide a novel insight into the complexity of circadian control ofglucocorticoid secretion,” researchers wrote.Plasma cortisol appeared to increase similarly after all macronutrient meals were compared with placebo, according to data. The carbohydrate meal stimulated adrenal secretion and extra-adrenal regeneration of cortisol in a similar way.

Eight lean, healthy men aged 23.5 years were randomly assigned to three different liquid isocaloric single macronutrient meals (carbohydrate, protein or fat) to test the contribution of peripheral cortisol regeneration to macronutrient-induced circadian variation of plasma control, according to data.

“Following the carbohydrate meal, plasma cortisol rose compared with placebo (P<.05),” researchers wrote.



Eating raises cortisol, eating carbs keeps it raised by inhibiting clearance from the blood stream.
