Croissant
Croissants pack 406 kcal into 100 g (3.5 oz), so a typical 60 g (2 oz) serving already adds up to about 244 kcal.

What it is and how to eat it
The Diccionario de la lengua española (DLE) lists the Spanish spelling cruasán, from the French croissant, meaning "crescent", and defines it as a crescent-shaped puff pastry roll. According to the Diccionario de americanismos, in Guatemala, Honduras, El Salvador and Nicaragua it is also called cachito, a word that in Venezuela, Peru and, in the plural, Bolivia refers instead to a savory roll filled with ham or cheese. This page covers the butter croissant according to USDA, with 406 kcal, 21 g of fat, 11.7 g of it saturated, 11.3 g of sugars and 8.2 g of protein per 100 g.
A medium croissant, 57 g (2 oz) according to USDA, provides 231 kcal, 12 g of fat and 6.4 g of sugars, with only 4.7 g of protein. The 2025 nutrition advisory on GLP-1 therapy suggests avoiding fatty or high-fiber foods in the first days of treatment, so in those days, and after a dose increase, half a croissant or saving it for later fits better. Once food is well tolerated, the same advisory lists enjoying portion-controlled treats among the habits to encourage and suggests eating protein first, so having it with a coffee with milk or a yogurt rounds out breakfast. For everyday mornings, the whole-wheat toast with ricotta and tomato is an option with more protein.
What the evidence says
In the Holt satiety index (1995), the croissant had the lowest score of the 38 foods studied, 47, compared with 100 for white bread, the reference, and 323 for boiled potatoes, seven times higher, in 240 kcal servings. In the same study, the fat content of foods was associated with less satiety, and protein, fiber and water with more. Its 11.7 g of saturated fat per 100 g add up to 6.7 g in a medium croissant, about 30% of the roughly 22 g that equal 10% of energy on a 2,000 kcal diet, the maximum WHO recommends (my calculation). The Wegovy (semaglutide) label puts nausea at 43.9% of patients in its 68-week trials, compared with 16.1% on placebo, and the NIDDK, part of the U.S. National Institutes of Health, lists high-fat foods among those linked to reflux.
Satiety
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 47 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.

Frequently asked questions about croissants
How many grams of protein are in a croissant?
A croissant, our reference serving of 60 g (2 oz), has about 4.9 g of protein. 100 g (3.5 oz) of croissants has 8.2 g of protein. That is 2 g of protein per 100 kcal.
How many kcal are in a croissant?
A croissant, our reference serving of 60 g (2 oz), has about 244 kcal. 100 g (3.5 oz) of croissants has 406 kcal. That is a high energy density.
How much fiber is in a croissant?
A croissant, our reference serving of 60 g (2 oz), has about 1.6 g of fiber. 100 g (3.5 oz) of croissants has 2.6 g of fiber.
Do croissants keep you full?
Barely filling for the calories they provide: our estimated satiety score is 1 out of 5. It is based on: high energy density. They were also measured in people: in the Holt satiety index (1995), with 240 kcal servings, they scored 47 versus 100 for white bread.
What should I know about croissants if I take Ozempic, Wegovy, Mounjaro, or Zepbound and feel nauseous?
Based on our tags, this is what matters about croissants on a GLP-1 medication. “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. “May worsen nausea”: a fatty or fried food; fatty meals are digested more slowly and can make nausea and heaviness worse. These are general guidelines, not medical advice: everyone tolerates foods differently.
What is a typical serving of croissants?
We use 60 g (2 oz) as a typical serving, roughly a croissant. That amount provides about 244 kcal, 4.9 g of protein, and 1.6 g of fiber. It is a reference for calculations, not a recommendation of how much to eat.
