I eat 20% protein, 77% fat, I eat protein with plenty of fat at each meal. Yes, protein has an insulin response, its widely known on this board, the difference between protein and carbs, is that we need protein to live, we don't need carbs. Eat your protein with a good amount of fat and the insulin response is much reduced. This is why milk has a higher insulin response than heavy cream. His articles seemed to suggest that low carbers were eating loads of protein, a few carbs and little else. If your diet consists of 20% protein, 60% carbs, 20% fat, I think its logical to assume that the insulin response will be far greater than 20% protein, 77% fat, 3% carbs.
He also makes very little mention of insulin resistance or its effects.
He also did not explain the fact that undiagnosed diabetics lose weight - often lots of weight. When they start on insulin or other meds that control insulin production their weight will stabilise and many will start gaining. I have seen this time and time again. He just mentions one diabetic drug that also has an effect on something else - as if this explains away the experiences of all the rest of the diabetics.
There's no argument that insulin isn't the only factor in weight gain/loss, but its one of the factors. The human body is complex and everything that influences weight gain and appetite is still not understood. There undoubtedly are other factors, but I believe insulin is one important factor.

MYTH: Since diabetics who inject insulin gain weight, this means that insulin is the reason for weight gain in non-diabetics
FACT: Amylin is co-secreted with insulin in non-diabetics; amylin has appetite suppressant and lipolytic effects
I would like to thank Dr. Stephan Guyenet for this information. I had known about amylin but hadn’t looked into it in any great detail. Amylin is a hormone that is secreted by your pancreas at the same time as insulin. Amylin decreases appetite, and also stimulates lipolysis (the breakdown of fat into fatty acids).
Type 1 diabetics do not produce amylin, and amylin secretion is impaired in type 2 diabetics. Pramlintide, a drug that mimics the effects of amylin, has been found to produce weight loss in diabetics.
This information demonstrates that the effects of insulin injection in a diabetic cannot be compared to the effects of physiological changes in insulin in a non-diabetic, yet many people erroneously make this comparison as if they are similar.
