Two people can eat the exact same two foods and have equal & opposite blood sugar responses to them. This implication is massive because what it does is it flips over the concept that there is a one-size-fits-all solution or diet. The implication of having a blood sugar response that is extremely high to one food and flat to another that somebody else has the opposite response to implies that there is a hormonal downstream effect that will be opposite as well. So, the amount of insulin that your body releases and the rate of release will be different.
