This diet's disadvantage is that it can be challenging for folks to gain muscle. This is because carbohydrates are essential to muscle building. With this diet, your blood sugar levels will be very low so that very little glucose will be sent to your muscle cells. The absence of vegetables and other nutritious items essential to a well-rounded diet is another drawback of this diet. Vegetables are essential for your general health and well-being since they include essential nutrients, vitamins, and minerals that are linked to nearly all known health benefits. Last but not least, a diet restricted to steak and eggs cannot be maintained over the long run. Your body cannot function effectively without carbohydrates in order to carry out certain biological processes.
