Self-Control Relies on Glucose as a Limited Energy Source (2007)

His reading is simplistic, but so is the article: there is no mention about different metabolic states, for instance.

The brain depends on a very small quantity of glucose to function - it arguably is more efficient with ketone bodies, for instance [1] - so covering not only glycolysis seems like an incomplete research.

Yes, this is another flaw, but there are much bigger flaws in their work!

Also, they only fasted people for 3h. I've sucked a lot of junk out of peoples' stomachs who have had longer fasts, so this is not even a glycogenolisis phase: they could easily have been digesting food still. The participants were students, so maybe some had drunk alcohol, which, like a ketone is a two-carbon molecule...
