Satiety

Very high energy density; moderate protein per calorie.

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 84 versus 100 for white bread. In other words, it was less 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

High in fiber
It has at least 3 g of fiber per 100 g. Fiber adds bulk and slows digestion, which contributes to fullness, and it helps keep you regular; constipation is a common side effect of GLP-1 medications. It is usually easier to tolerate when you increase it gradually and drink enough water.
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.
High energy density
It has more than 300 kcal per 100 g: a lot of energy in a small volume, so it is less filling per calorie. That does not make it a bad food; when your appetite is very low, a small serving can help you meet your needs.

Frequently asked questions about peanuts

How much protein is in a small handful of peanuts?

A small handful of peanuts, our reference serving of 25 g (0.9 oz), has about 6.5 g of protein. 100 g (3.5 oz) of peanuts has 25.8 g of protein. That is 4.6 g of protein per 100 kcal.

How many calories does a small handful of peanuts have?

A small handful of peanuts, our reference serving of 25 g (0.9 oz), has about 142 kcal. 100 g (3.5 oz) of peanuts has 567 kcal. That is a very high energy density.

Do peanuts have fiber?

A small handful of peanuts, our reference serving of 25 g (0.9 oz), has about 2.1 g of fiber. 100 g (3.5 oz) of peanuts has 8.5 g of fiber. They carry our “High in fiber” tag.

Are peanuts filling?

Barely filling for the calories they provide: our estimated satiety score is 1 out of 5. It is based on: very high energy density; moderate protein per calorie. They were also measured in people: in the Holt satiety index (1995), with 240 kcal servings, they scored 84 versus 100 for white bread.

What should I know about peanuts on a GLP-1 medication?

Based on our tags, this is what matters about peanuts on a GLP-1 medication. “High in fiber”: a good amount of fiber, which helps keep you regular; it is easier to tolerate when you increase it gradually and drink enough water. “Nutritious in small servings”: a lot of nutrition in a small volume, which is practical when you eat little. “High energy density”: a lot of energy in a small volume; when your appetite is very low, a small serving can help you meet your needs. These are general guidelines, not medical advice: everyone tolerates foods differently.

What counts as a normal serving of peanuts?

We use 25 g (0.9 oz) as a typical serving, roughly a small handful of peanuts. That amount provides about 142 kcal, 6.5 g of protein, and 2.1 g of fiber. It is a reference for calculations, not a recommendation of how much to eat.
