Summary
Let's review recommendations given to people with diabetes in regard to protein and try to determine if the research supports any or all of them.
"Proteins are foods like meat, cheese, and peanut butter." Only partly true; in most cases these foods are protein-plus-fats.
"Between 50?60% of protein becomes glucose and enters the bloodstream about 3?4 hours after eaten." Perhaps 50?60% of protein goes through the process of gluconeogenesis in the liver, but virtually none of this glucose enters into the general circulation.

Does 50?60% of protein become glucose and enter the bloodstream in 3?4 hours?
Gannon and Nuttall4 report that in 1915, Janney calculated that ~3.5 g glucose could be produced for every gram of nitrogen excreted in the urine as the result of a beef protein meal. Beef protein is 16% nitrogen; thus, 1 g of nitrogen is excreted for every 6.25 g protein. Theoretically, then, 56% of ingested beef protein, by weight, can be converted to glucose. However, this was only a theoretical calculation. Gannon and Nuttall point out that, shortly after that calculation was reported, a number of researchers showed that the ingestion of protein by subjects with and without diabetes did not result in an increase in blood glucose levels.
As an example, as early as 1936, Conn and Newburgh5 reported no effect on blood glucose levels after a meal containing a large amount of protein in the form of lean beef. Fifteen subjects with diabetes and three control subjects were fed breakfasts of glucose or carbohydrate or protein foods calculated to yield equal amounts of glucose (2 g protein/kg compared to 1 g carbohydrate/kg). The blood glucose response after carbohydrate or glucose was as expected. However, there was no increase in blood glucose levels after the protein meal even though there was a consistent rise in blood urea nitrogen indicating protein utilization. The finding that protein did not raise blood glucose levels seems to have been lost or misinterpreted over the years.
More recently, data from Nuttall et al.6-9 also indicate that peripheral glucose concentration does not increase after protein ingestion in subjects with and without diabetes.
Nuttall et al.10 gave nine subjects with mild type 2 diabetes
50 g protein, 50 g glucose, or 50 g protein and 50 g glucose and determined the plasma glucose and insulin responses over the next 5 hours. The glucose response to glucose was as expected, but the glucose response to protein remained stable for 2 hours and then began to decline. When protein and glucose were combined, the peak response was similar to that of glucose alone. However, during the late postprandial period, the glucose response was reduced by 34%. The insulin responses for protein and glucose were similar, but when combined the insulin response was nearly doubled. The glucose decrease when protein and glucose were combined was attributed to the increased insulin response to the combination.
