Stress hormone cortisol can cause your body to chew up muscle for energy.


You probably know that the stress hormone cortisol can cause your body to chew up muscle for energy.
According to the March/April ’11 Well Being Journal, foods that are high on the glycemic index, those that spike insulin quickly, rapidly increase cortisol.
That means if you eat a high-GI cereal for breakfast, you may be setting yourself up for elevated cortisol all day long.
Worse is having no breakfast: “Any time during the day that one does not eat within five hours of the previous meal or snack, cortisol levels rise.”
