This is simplistic. When I am on a low carb diet but for whatever reason decide to eat a doughnut or anything loaded with simple sugars, then I begin to be irritable, have cravings and generally less focused on work. The findings applies only for people who are stuck on high-carb diet
- zzalpha 9y agoYour reading is simplistic. This is talking about blood glucose levels, which is influenced by many factors, including glucose production in the liver.
- nazgul17 9y agoAlso, if your glucose level increases too much, your body deals with it by taking it all away, being you into a sugar low. Afair ;)
- leovonl 9y agoHis 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.

- wastra 9y agoYes, 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...
- darpa_escapee 9y agoA spike in blood sugar is not the same as not having depleted your normal blood sugar concentration.
- Chronicwhy 9y agoFructose causes cravings not glucose. Glucose is barely sweet, and gives you a instant energy.
