For some reason I have not been getting emails when threads are posted to, so I'm sorry I didn't respond to request for research sooner.
Note these are studies from metabolic wards which I find a lot more credible than authors of books who are trying to sell books.
So I have at least 10 studies, but these three I found particularly relevant to this thread with the last one being relevant to TINAJANE's diabetes question.
Energy intake required to maintain body weight is not affected by wide variation in diet composition.www.ncbi.nlm.nih.gov/pubmed/1734671
Weight-loss with low or high carbohydrate diet?www.ncbi.nlm.nih.gov/pubmed/8968851
Effect of high protein vs high carbohydrate intake on insulin sensitivity, body weight, hemoglobin A1c, and blood pressure in patients with type 2 diabetes mellitus.www.ncbi.nlm.nih.gov/pubmed/15800559
Both the high-carbohydrate and high-protein groups lost weight (-2.2+/-0.9 kg, -2.5+/-1.6 kg, respectively, P less than.05) and the difference between the groups was not significant (P =.9). In the high-carbohydrate group, hemoglobin A1c decreased (from 8.2% to 6.9%, P less than.03), fasting plasma glucose decreased (from 8.8 to 7.2 mmol/L, P less than.02), and insulin sensitivity increased (from 12.8 to 17.2 micromol/kg/min, P less than.03). No significant changes in these parameters occurred in the high-protein group, instead systolic and diastolic blood pressures decreased (-10.5+/-2.3 mm Hg, P =.003 and -18+/-9.0 mm Hg, P less than.05, respectively). After 2 months on these hypocaloric diets, each diet had either no or minimal effects on lipid levels (total cholesterol, low-density lipoprotein, high-density lipoprotein), renal (blood urea nitrogen, serum creatinine), or hepatic function (aspartate aminotransferase, alanine aminotransferase, bilirubin).
