The serving size analysis compares food weight density (in weight) against food energy density (in kcal) for the serving size recommended by the manufacturer.

Each box in the graph corresponds, approximately, to 33 kcal and, by direct matching, 33 grams in weight, as well. This way it is very simple to compare weight against energy, and ascertain whether a particular food [serving] provides more or less energy per weight. It may be that energy density higher than weight density provides less chances for the body to register sign of fullness, and, thus, the temptation to consume more, with a correlative overconsumption of energy. In contrast, the lower the energy density, the more chances those signals can be registered by the body, which may help feel satiated sooner and prevent overconsumption.

The graph is divided into sections, corresponding, approximately, to the energy density of a small snack (133 kcal), a large snack (266 kcal), a small meal (400 kcal), and a large meal (600+ kcal). A large snack may be equivalent to a light breakfast; a small meal may be equivalent to a hearty breakfast, a light lunch typical of Anglosaxon countries or a hearty lunch typical of Latin countries; and a large meal may be equivalent to a hearty dinner typical of Anglosaxon countries or a light dinner typical of Latin countries.

Overall, you can ascertain whether you are eating a particular food as a snack or a meal, and adjust servings as appropriate. For example, a typical 2000 kcal daily diet may be broken down into a small meal (breakfast = 400 kcal), two large meals (lunch and dinner = 1200 kcal), and three small snacks (= 400 kcal). In such case, a food with a density profile similar to the one represented in the graph can be eaten as a small snack (1 serving), a large snack (2 servings at once), a small meal (3 servings at once), or as a large meal (4-5 servings).
