This fitness trainer who has also worked with Mandy Moore, Ryan Gosling and Christina Aguilera says that sleep affects your metabolic process. “[Not getting enough sleep] produces a higher amount of the inflammatory stress hormone, cortisol,” she said in the interview.
“Cortisol has its time and place in our bodies, but not at night. Cortisol heightens our alertness, the last thing we need when we crave sleep.”
Borden also recommends you avoid sugar. “Sugars are inflammatory and trigger more sugar cravings, along with increasing inflammatory cortisol levels, which cause belly fat,” she said.
