It mentions eating a lot of fruit which I would say is controversial - normally fruit is considered a treat and veg is the main stay.
It also mentions squeezing the oranges to make juice which of course means you get the sugar with a lot less fibrous material which I imagine would cause an insulin spike.
I agree. Juice is usually a big no-no for me and fruit is something like one kiwi per day. Tons of veg for the fiber though and some lean meats.
The slower the digestion, usually the better I feel. Simple carbs just leave me feeling hungry shortly after eating, and I never drink my calories. Protein shakes are the exception to this rule
