I’ve written about Dr. David Unwin in previous posts. He is an inspirational GP in the UK who is using a whole food, low carbohydrate diet to reverse type 2 diabetes and obesity and saves the NHS thousands of pounds in medication costs.
A UK doctor puts 18 patients with type 2 diabetes on a low carb diet with amazing results
UK doctor saves government £45K by using low carb diet to treat type 2 diabetes
This graph shows just how little his Norwood Surgery spends in drug costs compared to other practices. 
A documentary has been shown in the UK recently which clearly outlines the problem with highly processed carbohydrates (the beige and white ones), and follows a group of people with type 2 diabetes and obesity as they change their diets to follow these prinicipals. What is fantastic is that none considered the change difficult, or restrictive.
Here is the documentary. Happy watching.
