Hi Tickerguy, long time lurker (10 years+) I know going low carb changes the metabolic reactions in your body. From memory, roughly 50% more energy per oxygen molecule - with the trade off of less peak energy. Is this correct? and if so, is it taken into account with your numbers above? Ie being low carb/keto makes you more efficient with the available oxygen?

I know that when I am low carb, I feel much more efficient with my oxygen and less likely to get out of breath. Is this just a placebo type effect?

Well, "less peak" is not really true for 99.9% of people. Can you outperform in CERTAIN sporting events on a carb-laden diet? Sure. How many people run Olympic-level (at that level of performance) 100 meter sprints? That's what I thought.

It's not really that you're more efficient with O2 transport, it's that lipids have ~9kcal/gm where carbs and protein each have 4. So you have more energy available per unit of mass. In addition you need less water to process it, so when you shift to ketogenic function you tend to piss out a couple of pounds of water right up front. That's a one-timer, however, and if you eat a few fries you'll drink it right back up.

You boomers must be pissing your pants right now. We are finally going to be rid of you and your RVs, mobility scooters, and type II diabetes medicine costs sucking money out of the healthcare system.

Good luck with running that shit for any length of time around here.
