Chronic stress and a high-fat, high-sugar diet decrease stimulation adrenaline receptors involved in burning fat and reducing appetite notes a recent paper.

The receptors are called beta-adrenergic receptors.

Stress plus High-Fat, High-Sugar Diet Reduces Noradrenaline

Stress combined with a high-fat, high-sugar diet reduces noradrenaline found in body fat

Stress in mice fed a high-fat, high-sugar diet decreased the amount of noradrenaline found in body fat.

 

Adrenaline Levels Reduced

Adrenaline levels lower in mice fed a high-fructose diet

Adrenaline levels found in the blood were also found to be reduced in mice fed a high-fat, high-sugar diet.
