In general, a food with:
- 40 calories per serving is low in calories
- 100 calories per serving is moderate in calories
- 400 calories or more per serving is high in calories
For example, the nutrition label pictured above contains two servings in each container. So if you eat the whole thing by yourself, you are actually eating 500 calories (250 calories per serving X two servings), and not just 250 calories as the label makes it appear.
A common way that people overeat is by consuming oversized portions and underestimating how many calories are in the foods they eat. To help avoid this, you might choose to buy single serving packages or remove a single serving from a larger package and don't eat out of the bag or box itself. Repackaging large bags or boxes of food into smaller, single serving packages can also be helpful.
