And those on Keto/Paleo diets with near zero carb but who are burning Ketones instead?
The Graphic all but says ONLY carbs can provide energy. What did/do the Innuit (Eskimo) eat?

The graphic doesn't say that only carbohydrates can provide energy - in the second panel, it highlights that 'aerobic respiration uses fatty acids and glucose to make ATP'.

This infographic implies that the sole source of energy during exercise is carbohydrate. This is certainly not the case, free fatty acids are certainly used during exercise and, in fact, trained athletes clearly utilise fats as the preferred energy source during extended exercise.
Andy Brunning (May 27, 2020 4:28 AM)
The fact that fatty acids are also used is mentioned in the middle panel.

We spend years teaching students that energy cannot be produced. It is released or transferred.

Where is ATP stored?
