244. 8 Nutrition Mistakes Sabotaging Your Performance
After years of bodybuilding, coaching, and pushing my body to extremes, you start to see patterns you can't unsee. People chase fat loss harder and harder, slash calories, live on stimulants, and follow rigid nutrition rules that promise control and discipline. It works for a while. Then energy drops. Recovery slows. Hormones take a hit. Inflammation creeps up. And the cycle starts all over again.
In this episode, I break down eight nutrition mistakes I see repeatedly sabotaging health and long-term progress. We talk about extreme calorie deficits, processed protein overload, missing micronutrients, cutting fats, binge eating disguised as cheat days, bro science diets, stimulant dependence, and removing food groups without understanding individual biology. I explain how these habits impact thyroid function, hormones, gut health, brain chemistry, sleep, and biological aging.
If your goal is strength, resilience, and a body that still performs decades from now, this episode will challenge how you think about nutrition, discipline, and sustainability.
