We are typically instructed to eat until we are satiated. The problem is that different foods have drastically varying effects on appetite and fullness. For example, 200 calories of a chicken breast may satisfy you, whereas 500 calories of a cake may not. As a result, reducing weight is more than just eating till you’re full. It all comes down to eating the correct foods to keep you pleased while ingesting as few calories as feasible

How Food Can Make You Feel Filled
Several factors influence food’s satiety value, or how satisfying it is about its calorie content. A satiety index scale is used to calculate the calorie/satiety ratio. The satiety index measures a food’s ability to fill you up, suppress your hunger, and help you consume fewer calories throughout the day. Some foods are simply better at satisfying hunger and preventing overeating than others.
