Cortisol Levels Are Raised
Even though coffee is known to help reduce the risk of the development of type 2 diabetes, if you drink it on an empty stomach, that is not the case. Experts have also found that drinking coffee on an empty stomach can raise cortisol levels, which is the stress hormone. That also results in insulin resistance and weight gain, which both increases the chances of the development of type 2 diabetes. Drinking coffee with food will help neutralize this effect.
