A great deal of biological swapping happens in a kiss, with one fun fact noting the transfer of 0.5 milligrams of protein. But do kisses have protein in a meaningful, nutritional sense?

According to some research, a simple kiss can burn around 2 to 3 calories per minute, a fact that intrigues many.

While a delightful act of affection, the reality of its caloric impact is often misunderstood.
