[QUOTE=Lewis;870910]Yeah, very interesting book. One of the premier books on low-carb.
You don't give the context or the page reference. I think this is in the context of sustained exercise -- and that mainly aerobic but sometimes passing into anaerobic.
Thanks for reply, good discussion, think it will help the OP.
It is on page 55 of 'The art and science of low carb performance', I have read it a few other places of the last few months.
They stress in the above book the importance of testing ketones via a blood testing kit, and not by the sticks as they are not very accurate.
Also, they stress if you are keto adapted, you shouldnt carb-up after exercise. If your not keto-adapted then it's better to do the post workout carbs.
