Following high protein diets are the latest fads. My clients who want to build muscle or gain weight want to eat lots of protein by drinking liters of milk, eating lots of chicken or more than 5 eggs in a day.
It all comes down to how much you need as per your body requirements or health status. Normal requirements are 1 gram per kilogram of body weight for a man with ideal body weight. 1.2 grams per kilogram for an underweight person and 1.5-2 grams per kilogram for patient with high fever, burns or accident cases with blood losses.
A very high protein diet can cause the kidneys to work harder and cause the teeth and bones to excrete calcium. Most of the protein foods contain fats and can increase the risk for heart disease, certain cancers, weight gain and in a few cases high blood pressure. Uric acid levels too can get elevated which can cause aches and pains in the joints.
High protein food can be low in fiber too which can cause constipation and many other diseases.
A healthy diet should have 15-20% protein. So consult with a dietitian before you do changes in your protein intake and will be the right person to to determine your protein intake.
