Does the body store excess calories from proteins like it does carbohydrates that are not used as fats?

Protein StorageThere are a lot of details to this answer but here is a nutshell version.

All foods that we eat are made up of fats, carbohydrates and proteins. Carbohydrates are the primary fuel source. Fats supply fuel but fat is the substance our bodies use to store extra calories. Proteins are used to build and repair muscles, cells, etc.

Our bodies will use what it needs from the foods we eat. If we eat too much of any of these nutrients, the body can store them as fat. If the body needs energy, it can use any of them to make energy but prefers to use carbohydrates.

If we take in more protein than our bodies need, we can convert protein into energy or we can store it as fat. To do this, our bodies use extra water, which increases our chances of becoming dehydrated.
