does intermittent fasting increase insulin?
Intermittent Fasting and insulin resistance. So I've heard two theories about intermittent fasting, both from several places. Theory 1: Intermittent fasting forces our body to adapt. In particular it increases our sensitivity to insulin (the opposite of type II diabetes) which is a good thing. Theory 2: Intermittent fasting is bad for us because it causes (relative) insulin spikes.
