Cortisol is a stress hormone released when we are under emotional or physical stress. It can also lead to weight gain, especially belly fat due to numerous reasons. From fat storage to slower calorie burning, here are a few ways how it contributes to belly fat. Tap to know!

Stores Fat

Cortisol (stress hormone) is produced when we are under stress, which stores energy as fat, especially as belly fat. It is a coping mechanism against danger even if there's none.

Disrupts Sleep Cycle

Stress also disrupts our circadian rhythm (wake-sleep cycle), making it hard for us to fall asleep. Poor sleep quality can lead to weight gain, especially belly fat.

Increases Hunger Hormone

Stress can increase the release of ghrelin (hunger hormone), causing you to overeat, especially calorie dense food like sweets or fast food.

Hormonal Imbalance

Cortisol can interfere with our hormones like leptin, insulin, oestrogen, and testosterone, leading to more fat gain and less fat burn.

Slows Calorie Burning

High cortisol levels can slow down calorie burning by affecting thyroid function and metabolism. Consuming extra calories can also lead to extra fat storage.
