Fuhrman's diet isn't vegan or vegetarian, but it would be easy to modify it.
You're being uncharacteristically charitable toward a high-carb, low-fat diet.
I see no charity in any my posts on this topic.
I am being, characteristically, as objective and as accurate as possible.
Not sure where you get the "high-carb low-fat" assessment. The pie chart doesn't show that at all.
This diet pretty much eliminates fast simple carbs (refined sugars, processed foods and flours). It includes complex starches (beans; whole grains; fruits). It limits potatos. The vegetables listed are all allowed on a LCHF diet.
The fruits wouldn't be allowed on LCHF.
From what I know so far I'd say this is a moderate carb; moderate fat diet. It's probably very similar to the low GI or low GL diets.
Probably not as effective or healthy as LCHF, but probably more effective and healthy than LFHC-CR or just CR.
