Fat oxidation in elite athletes, active healthy individuals and people with metabolic syndrome as a function of power
Thank you for this. Reading about metabolic syndrome now. It does sound like me. I struggled with low blood sugar at a young age, and I still have to be mindful about it. My family history now indicates a 90% chance of me eventually becoming diabetic. Through much of my adult life, physical labor has been limited by energy, and I have had to plan eating around working. The way you describe it really rings a bell.
