In this short instructional video, Eric Roberts demonstrates how the physical volume of food relative to its calorie content influences satiety during a calorie deficit. Using a bowl as a visual metaphor for the stomach, he contrasts 140 calories of olive oil—occupying almost no space—with 140 calories of strawberries, which fill the bowl substantially. He explains that low‑calorie, high‑volume foods keep the stomach fuller longer, making it easier to adhere to a calorie‑restricted diet. He reinforces the point with concrete examples: a whole container of spinach (~50 calories) and large servings of blackberries and raspberries (~150 calories). The core message is that choosing foods with low energy density (high volume, low calories) can improve fullness and support weight‑loss goals.
