In this short instructional video, Eric Roberts explains how to keep hunger at bay while staying in a calorie deficit by focusing on the volume of food rather than its calorie count. He illustrates the concept with a visual metaphor of the stomach as a bowl that registers volume, not calories, and compares two equal‑calorie portions: a small amount of peanut butter versus a large serving of berries. The larger, low‑calorie, high‑volume foods stretch the stomach, signal fullness to the brain, and suppress hunger. Roberts extends the idea to other food swaps—popcorn instead of cereal, potatoes instead of chips—showing that you can eat more food for the same calories, making a deficit feel less like dieting. He concludes with a call to follow for more straightforward fitness advice.
