High sugar stimulates insulin and insulin will do two things. Insulin is a fat making hormone but it also prevents the burning of fat. If you are in a chronic stress state, your body is not going to be able to get you into ketosis because of high cortisol and the high sugar and the high insulin so it is going to be really hard for you to get in the state of fat-burning if you have high cortisol.
You must first understand why you would get weight gain with adrenal fatigue and how it all works.
There is a condition of hypercortisolism that is high cortisol. The adrenal gland has an outside and an inside. The outside makes cortisol, the stress hormone. There is a condition called Cushing’s syndrome. It is is high cortisol. Hypercortisolism means too much cortisol. It does not develop quickly. It is the same with adrenal fatigue, it starts at a certain point and it gradually gets worse and worse. Just like you have insulin resistance, pre-diabetic and then eventually a diabetic.
Carbohydrates are highly addictive. We are conditioned as children to feed a carb addiction – most children consume large amounts of sugar daily. Sugars and refined grains are added to baby food, cereal, candy, and virtually all processed foods.
Carbs are so addictive because they trigger two hormones: dopamine and serotonin. These are pleasure and happiness hormones. This sugar addiction is real and it will literally control you to a point where you are completely out of control.
Over time, an addiction to carbs becomes stronger and stronger.
