Although it may seem counter intuitive, the best way to treat reactive hypoglycaemia is through a low carb diet
. This should be very low carb
, moderate protein, and with enough healthy fats that you meet your energy needs.

I gave this plan to some friends. It is a low carb, moderate protein, higher fat approach.
