Well done everyone. Lots of success stories.
Welcome to the newbies.
BorderCollie Insulin Index:
It was proposed in a paper "An insulin index of foods: the insulin demand generated by 1000-kJ portions of common foods," Am J Clin Nutr 1997 66: 5 1264-76.
However, there hasn't been much work since on how it could be helpful or used. Doesn't seem commonly used by doctors or in diabetes care.
The insulin index of a food represents how much it increases insulin in the blood during the two hour period after eating. In contrast, the Glycemic Index measures blood glucose levels.
High protein foods were found to have a high insulin index, although they have near-zero GI.
I could be wrong, but I think it's only something that might affect people who take insulin.
Those with T1 seem to benefit from low carb, but need to work with their doctors to adjust insulin dose, because higher fat can increase their insulin requirements, e.g.

For the rest of us, low carb is quite straightforward:
As carb intake falls below a certain daily level, usually about 100g, the liver will start generating the glucose necessary for brain function etc from glycerol in lipids (fats) and amino acids in proteins.
This process is called gluconeogenesis
