Protein does not turn into chocolate cake

From (The Journal of Clinical Endocrinology & Metabolism, Volume 86, Issue 3, 1 March 2001, Pages 1040–1047, Effect of Protein Ingestion on the Glucose Appearance Rate in People with Type 2 Diabetes. M. C. Gannon J. A. Nuttall G. Damberg V. Gupta F. Q. Nuttall.):

Amino acids derived from ingested protein are potential substrates for gluconeogenesis. However, several laboratories have reported that protein ingestion does not result in an increase in the circulating glucose concentration in people with or without type 2 diabetes. The reason for this has remained unclear. In people without diabetes it seems to be due to less glucose being produced and entering the circulation than the calculated theoretical amount. Therefore, we were interested in determining whether this also was the case in people with type 2 diabetes. Ten male subjects with untreated type 2 diabetes were given, in random sequence, 50 g protein in the form of very lean beef or only water at 0800 h and studied over the subsequent 8 h.

Protein ingestion resulted in an increase in circulating insulin, C-peptide, glucagon, α amino and urea nitrogen, and triglycerides; a decrease in nonesterified fatty acids; and a modest increase in respiratory quotient.

The total amount of protein deaminated and the amino groups incorporated into urea was calculated to be ∼20–23 g. The net amount of glucose estimated to be produced, based on the quantity of amino acids deaminated, was ∼11–13 g. However, the amount of glucose appearing in the circulation was only ∼2 g. The peripheral plasma glucose concentration decreased by ∼1 mM after ingestion of either protein or water, confirming that ingested protein does not result in a net increase in glucose concentration, and results in only a modest increase in the rate of glucose disappearance.
