In the third episode of ClimbSci, we discuss fat and how it fits into energy provision and health.
If you have any questions or comments regarding the show, want us to investigate something specifically, or know any guests we should interview; please leave them in the YouTube comments, or head over to Brian’s page facebook/climbingnutrition and leave them on the wall.
Energy System Contribution
As mentioned in previous podcast on Carbohydrate, the energy systems overlap in their contribution to overall energy needs. Glucose (carbohydrates) are most importantly used without oxygen present “anaerobic glycolysis”, and with oxygen present “aerobic glycolysis”. However fat however can only be metabolised when oxygen is present “oxidative phosphorylation”.

All studies below were specifically cited in this episode. In general, if a study was not cited in the episode, we do not cite it here—even if we base a claim on it or similar studies. Expertise is a culmination of the time spent studying a topic, and it is not always practical to fully cite the research that has informed our professional opinion. If you have a question regarding the source of a specific claim we make, please contact us.
