Meat contains only insignificant amounts of carbs. The human body can convert protein to carbs (glucose specifically) but the rate at which it can do it is limited, and my guess is that if it can't burn glucose, a metabolically-healthy body will burn fat (rather than glucose made from protein) until the diet has been quite deficient in calories for at least 3 days.
