Dr. Richard Bernstein advocates for a low-carbohydrate, high-protein diet, using medium and long-acting insulin for protein and fat metabolism, to maintain blood glucose levels close to normal.

“he figured out that if he avoided in carbohydrates and if you give medium and long acting insulin to cover protein and fat and basal metabolic requirements that you get blood glucoses very very close to normal and he typically prescribes a low carb high protein diet it's not low carb high fat it's not ketogenic”
