Because one of its role in body fat storage, insulin often gets a bad rap in the ancestral health community.
Managing insulin secretion through diet is a good strategy for losing weight, but it is also important to understand that insulin performs vital functions in your body and is essential for your body to survive at all.
This short video from Kahn’s Academy is a good beginner’s guide to the function of insulin in fuelling your cells with glucose.
For an explanation of what happens to the glucose after it has entered your cells, see this video lecture by Doug McGuff, M.D.
One of the things my blog has been missing, is a dissertation of how the Paleo/Primal diet actually works. I have been wanting to post an article on this, because understanding the science made a big difference to me. I would like to think it could also make a difference to others.
The problem is the science is not easy to explain. To be honest I have been putting off writing an article about it because I knew it would be time consuming and challenging.
So, I was very pleased to find this video with Dr. Doug McGuff where he goes through the biochemistry of human metabolism to explains obesity, diabetics and why eating Paleo/Primal works for optimal health.
I have read a lot of material on how Paleo nutrition works, but this is by far the clearest explanation I have come across.
The whole video is 1 hour and 38 minutes long, but I have embedded it so it only plays the part where Dr. McGuff explains current understanding of metabolism. If you want to understand the science of Primal eating, these 36 minute are going to be worth your while.
