Made a post for some advice on my programming a little while back, and am getting a ton of heat for it.
I'll have the last laugh when my strength continues to climb fueling on a diet LOW in carbs tapping into my own fat stores for performance and longevity. There is evidence that fat burning not only produces more ATP than glycolysis (147 ATP per mole of fat vs 38 ATP per mole of glucose), but also produces less ROS (free radicals) within the cell to lower oxidative stress. Not only that, but with fat burning/fasting and drinking a ton of natural spring water allows me to tap the PPP (pentose phosphate pathway) to restore muscle glycogen SANS carbs! Not only that, but the PPP maximally restore NADPH levels within the cell to maximize anti-oxidant levels (i.e. glutathione) to further protect from oxidative stress while also providing the reducing agents for cholesterol and steroid hormone biosynthesis (yes, this means MORE T).
The carboholic trainees who think they need 30-60% of their calories from carbs may see better performance in the short run because they are too impatient for the 24-36 month period of fat adaptation, but at the expense of depleting their stem cell supply leading to eventual disease.
Accessing the PPP through a ketogenic diet with occasional/seasonal carb loads is the pathway I've found that links performance and longevity, something most individuals would see as a paradox, given training is an additional stressor in an already OVERstressed world we live in today.
