So I've concluded another experiment with fasting and supplementation.

I previously found that fasting without supplements was not effective.

Last week I tried supplements, but while fasting, ate a lot of carbs like pizza, ice cream, etc. I wanted to see how much that plays a role.

I gained 3 pounds, so you need to you do all three. You need to fast, limit carbs, and take supplements for insulin resistance. If you don't do all three, you won't succeed.
