In this solo YouTube talk, Eric Roberts warns that chronic high‑intensity interval training (HIIT) can sabotage weight‑loss goals by disrupting hunger hormones, increasing appetite, and impairing sleep. He explains that excessive HIIT elevates evening cortisol, which interferes with the body’s natural wind‑down, leaving trainees ravenously hungry and unable to rest. As a result, people who train five to six days a week may see the scale stall despite effort. Roberts challenges the common 80% diet / 20% workout narrative, arguing that diet and exercise influence each other and should be considered roughly a 50/50 partnership for effective results.

One of the most overlooked side effects of excessive high-intensity interval training is what it does to your hunger, appetite, and sleep. Chronic high-intensity training disrupts the hormones that control your hunger, making you hungrier than you would be with moderate-intensity training. It also disrupts your sleep quality by keeping your cortisol elevated in the evening, which interferes with your body's natural wind-down and sleep process. You've got somebody training 5 to 6 days a week who's ravenously hungry, who can't sleep, And they're wondering why the scale isn't moving. The workouts are creating the problem that is preventing the results. And this is my issue with people who say it's 80% diet, 20% workouts. Your diet impacts your workouts. It's 50/50.
