Eating too much protein
One of the most common keto mistakes for beginners is eating too much protein. The excess protein undergoes gluconeogenesis to be converted into glucose, the same level of danger as when you eat a lot of starch. When you eat too much protein, your body needs to burn off all the glucose made up of protein before it starts burning fat. This can slow down your transition to ketosis and destroy all your efforts at keto.
So, during the keto diet, you also need to pay attention to consuming an acceptable amount of protein. The US Dietary Guidelines for Americans recommend 0.8 grams of protein per kilogram of body weight for a sedentary adult (that's 0.36 grams of protein per pound of body weight or 65 grams per day for the typical 180-pound American).
