Putting this info in here so I can easily find it again. It is an interesting exercise in understanding your insulin.
The “Insulin Load” of any given food is calculated as follows:
Insulin Load = Carbohydrates(g) – Fibre(g) + [.56 x Protein(g)]
Insulin load is explained here:
Dr. Phinney in The Art & Science of Low Carbohydrate Living, The Art & Science of Low Carbohydrate Performance says a load of 125g. will result in reaching the ketogenic threshold, but some people have found 75g (as per some Paleo oriented scientists feel) is the threshold. This is probably due to the amount of damage you have already done to your body.
