Dr Benjamin Bikman (researcher) gives results on insulin after research subjects (otherwise healthy) are purposely over fed carbohydrates for a week and what it does to their fasting insulin levels. Spoiler: not a good thing. This info starts around minute 23 or 24 if you want to skip ahead. If you want to find out why this is bad, go back and watch the whole video. Or skip about ten minutes back to get the meat of it.

Bikman is one of my heros as far as metabolic research goes concerning my health.
