A daily intake of 2,500 calories contributes ~100 g of protein—about twice what is needed to replace protein lost on a daily basis. Excess amino acids must be converted into other storage products or oxidized as fuel. Therefore, in theory, the excess ingested protein could, through the process of gluconeogenesis, produce glucose. This would mean that 100 g of protein could produce ~50 g of glucose. This has been the basis of the statement that if about half of ingested protein is converted to glucose, protein will have one-half the effect of carbohydrate on blood glucose levels. However, this belief has been challenged
