Hey Doc Vellers, and Doc Tim,

Mitochondria, wow. I took a course on them (MOOC from Harvard) and there is so much to them. Not to mention you get them from your Mom. How they function is down to Quantum delivery of a single electron- fascinating stuff. Like a lot of Science, and Dr. Vellers spoke of this well- original questions lead to more questions, not answers. Sometimes, what looks like there should be an obvious correlation -if not causality - like Sex Hormones determining weight gain, and inactivity, there are not.
So that leads Doc Vellers to more research: because if the sex hormones are not the culprits, then what pathway is? Who would have thought that mitochondria, and not the hormonal pathways would be candidates for how we over eat, and become inactive? Well, I guess if you understood how the ATP, ADP, Pyruvate pathways works, you might suspect that energy might be at the base of the pathway.
Just brilliant stuff to listen to. Lots to unpack. Even more than the science, I loved the Dr's take home message...take advantage of opportunities. Yep. Do. LOL

Smiles, Kevin

Thank you so much for your response- it is always nice to receive messages from people that really show they were intellectually curious and listening to a conversation/talk, as you were- thank you! As for your first question, we do know that the primary sex hormones have a regulatory role on voluntary physical activity, they were just not part of the pathway through which overfeeding decreases activity. The regulation of diet on an individual's drive to be active is a question that has really just started to be investigated. I am particularly interested in the role of the mitochondria given the primary role of the mitochondria is energy regulation- which both diet and activity revolve around... So, I think you are right, energy regulation through the mitochondria could be at the base of the pathway regulating dietary influences on activity... All very new, but interested in where this may lead... Thank you again for your comments and taking the time to listen!!
