No but it would explain why so many have difficulty. This isn't all that interesting to be honest. We've known for a long time that energy levels have a direct effect on brain function. That self control is a "function of the brain" is obvious and subject to the same principals.

Garbage in, garbage out as the saying goes. Proper diet will improve brain function and "self control".

From the paper:

"Resisting the temptation to eat the cookies presum- ably depleted an energy resource that could otherwise have been used to persist on the subsequent task"

To your point, the best way to diet then would be to avoid the temptation which would mean less use of glucose in the resisting of it.
