An incredibly complex, naturally occurring molecule known as a protein is made up of amino acid residues connected by peptide bonds. All living things contain proteins, which are the building blocks of numerous vital biological substances like enzymes, hormones, and antibodies.
Lack of protein can result in muscle mass loss, which reduces strength, makes it more difficult to maintain balance, and slows metabolism. When your cells don't receive enough oxygen, it can also cause anemia, which makes you exhausted.
While an excess of amino acids is often eliminated, an excess of protein is typically retained as fat. Over time, this may result in weight gain, especially if you try to boost your protein consumption while consuming too many calories.
