In this short YouTube segment, Eric Roberts explains that staying in a prolonged calorie deficit causes the body's metabolism to slow, meaning further calorie cuts are needed to continue fat loss. He likens the effect to removing a heavy backpack, which reduces the effort required for daily activities. Roberts notes that this metabolic slowdown typically appears after a person has lost 30–50 pounds. He emphasizes that preserving or building muscle through weight training and a high‑protein diet is crucial because muscle tissue keeps metabolism elevated. The segment ends with a call‑to‑action directing viewers to a free calorie‑deficit calculator linked in his bio.

Yes, Robert, what do you want now? More money? A check? A car? My soul?
When you're in a calorie deficit for too long, your metabolism is going to slow down, which means you would have to decrease your calories even more if you want to keep losing fat. But here's what nobody tells you. Number 1, this is a normal part of of losing weight. Imagine if you wore a 50-pound backpack around all day long. When you finally took off the backpack, your body wouldn't have to work as hard and you wouldn't burn as many calories. And second, this only happens when you start to lose at least 30 to 50 pounds. And third, this is also why lifting weights eating high protein and building muscle is so important when you're trying to lose weight because the more muscle you have, the higher your metabolism will be.
