Is insulin resistance worse in the morning?

Dawn phenomenon is the result of hormones releasing in the body in the early morning – predominantly growth hormone, cortisol, epinephrine, and glucagon – which in turn increase insulin resistance.

Why does insulin spike in the morning?

When your blood sugar drops, your body releases stored sugar — mainly from the liver — and overcompensates. If your blood sugar level drops in the middle of the night, this overproduction of sugar can cause a high level in the morning. This is called the Somogyi effect.

Are you more insulin resistant at night?

For example, when you stay up late, your body makes more of the hormone cortisol, which affects how insulin works. Also, growing evidence shows that disrupting your body’s biological clock (AKA your circadian rhythm) by being awake at night can make your cells more resistant to insulin.
