I have been an endurance sport and ultrarunner athlete for 31 years. It's not a perfect journey. But, I truly believe one must research and determine a personal diet and fitness plan. Grams of protein? Low carb? No carb? LSD or HIIT? It's a propaganda fest. I'd suggest each of us should vet the popular diet and fitness programs and determine what's right for us, in our time, within our own psychological context. When we develop and devise our own journey, we hold the knowledge, knowledge becomes power, and through power, we gain consistency.
