So let's take a look at the 6 most important side effects of eating too much protein.
1. Weight gain
A diet rich in proteins helps you lose weight. But when this exceeds the safe limit, it may result in weight gain. In the long run, a diet high in terms of protein may result in weight gain. When the body excretes an excess of amino acids, the surplus is stored as fat. This happens especially when you increase your calorie intake just to consume more proteins. According to a 2016 study, weight gain happens when proteins are used to replace carbs and not fat.

Consuming more proteins is unlikely to create kidney problems in healthy people. However, the ones with kidney disease may expose their kidneys to some damage.

5. Loss of calcium
According to a 2013 study, high levels of protein are linked to loss of calcium in the body. This is sometimes linked to osteoporosis and poor bone health. This happens because consuming too much protein induces your body to excrete calcium through urine. As a result, your dietary requirement of calcium increases. So if you do not increase your calcium intake to make up for this loss, you increase your risk of osteoporosis later in life. So the more protein you take the more calcium you will lose.

To break down protein in the body, put it to use and to excrete the waste, a lot of water is required. So if you do not drink enough water to make up for the requirement, you may feel dehydrated. To prevent this from happening, you must increase your water intake when you increase your protein intake, to make up for the loss. This loss of water will start reflecting on your skin and hair.
