Satiety

Low energy density; moderate fiber 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.

This food was measured in people: in the satiety index by Holt and colleagues (1995), which compared 240 kcal servings of 38 foods over two hours, it scored 118 versus 100 for white bread. In other words, it was more filling than the same calories of white bread. Source: Holt SH, Miller JC, Petocz P, Farmakalidis E. A satiety index of common foods. Eur J Clin Nutr. 1995;49(9):675-90.

What to keep in mind on a GLP-1 medication

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.
Low energy density
It has 100 kcal or less per 100 g: plenty of volume for few calories, which helps you feel full. On a GLP-1 medication, which already reduces your appetite, make sure these foods do not push protein foods off your plate.

Fairly filling for the calories they provide: our estimated satiety score is 4 out of 5. It is based on: low energy density; moderate fiber per calorie; high water content. They were also measured in people: in the Holt satiety index (1995), with 240 kcal servings, they scored 118 versus 100 for white bread.

Are bananas a good choice on a GLP-1 if I have nausea?

Based on our tags, this is what matters about bananas on a GLP-1 medication. “Easy to digest”: a soft or low-fat food that many people tolerate well when they feel nauseous or get full quickly. “Low energy density”: plenty of volume for few calories; make sure it does not push protein foods off your plate. These are general guidelines, not medical advice: everyone tolerates foods differently.

How many grams or ounces are in a serving of bananas?
