Satiety

Low energy density; a lot of protein per calorie; high water content.

The 1 to 5 score is our own estimate: it starts at 1 point, adds points for low energy density, for protein and fiber per 100 kcal, and for the water in solid foods, and subtracts points for drinks with calories. It is useful for comparing foods with each other; it is not a measurement in people.

What to keep in mind on a GLP-1 medication

High in protein
It has at least 10 g of protein per 100 g and 6 g per 100 kcal. Protein is the most filling nutrient per calorie and helps preserve muscle mass during weight loss, which matters especially when a GLP-1 medication reduces your appetite.
Easy to digest
It is a soft or low-fat food that many people tolerate well when they feel nauseous or get full quickly. This is an editorial judgment based on common patient guidance, not a measurement: everyone tolerates foods differently.
Nutritious in small servings
It provides protein, healthy fats, or other nutrients in a small volume. That is practical when you eat little and every bite needs to count.
