Why does cortisol cause weight gain?

The purpose of cortisol is to increase your energy in stressful situations, like being chased by a tiger. However, when that energy (which is sugar in this case) isn't being used—like those who work at a desk—it gets stored as fat. Even worse, cortisol converts your muscle into sugar, which can reduce your muscle mass.

Cortisol also has another function. Along with creating fat, it prevents the burning of fat. This means that you'll have a hard time to get into ketosis.

The key is to start by figuring out where the stress is coming from. Then, you can work towards lowering it. Next, start on Healthy Keto and intermittent fasting. Finally, make sure you are getting plenty of vitamin D, vitamin C, and potassium.
