What it is and how to eat it
The red beans on this page are what USDA calls red kidney beans, a variety of the common bean (Phaseolus vulgaris) with red, kidney-shaped seeds. The Diccionario de americanismos records habichuela in the Dominican Republic and Puerto Rico for the frijol, "especially the red one", and the DLE, the Spanish-language dictionary, records poroto, meaning judía, in Argentina, Bolivia, Chile, Ecuador, Paraguay, Peru and Uruguay. This page covers red kidney beans boiled without salt, with 127 kcal, 8.67 g of protein and 7.4 g of fiber per 100 g according to USDA.
A 150 g (5.3 oz) serving provides about 190 kcal, 13 g of protein and 11.1 g of fiber. The 2025 nutrition advisory on GLP-1 therapy lists legumes among the foods to encourage but suggests avoiding very high-fiber foods in the first few days of treatment and, for constipation, increasing fiber gradually. The NIDDK, part of the U.S. National Institutes of Health, lists legumes, including beans, among the foods that can cause gas, and the Wegovy (semaglutide) SmPC lists flatulence and abdominal distension among its common adverse reactions, so in those days half a serving, well cooked, may be enough. In a salad with hard-boiled egg or tuna, or in a stew with chicken, the dish adds even more protein.
What the evidence says
A 2016 meta-analysis of 21 trials in the American Journal of Clinical Nutrition found a modest weight loss of 0.34 kg over about 6 weeks with a daily serving of pulses. With 7.4 g of fiber per 100 g and 27% of their energy from protein, they meet the EU conditions for "high fibre" (at least 6 g per 100 g) and "high protein" (at least 20% of energy) claims, and their 2.94 mg of iron exceed the 2.1 mg for "source of iron" (Regulations (EC) No 1924/2006 and (EU) No 1169/2011). The FDA warns that raw or undercooked red kidney beans contain a lectin, phytohaemagglutinin, that can cause extreme nausea, vomiting and diarrhea with as few as four or five raw beans, and advises boiling them for at least 30 minutes and not cooking them in slow cookers, which do not get hot enough to destroy it.
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.

Frequently asked questions about cooked kidney beans
How much protein does a 150 g (5.5 oz) serving of cooked kidney beans have?
100 g (3.5 oz) of cooked kidney beans has 8.7 g of protein. A typical 150 g (5.5 oz) serving has about 13 g of protein. That is 6.8 g of protein per 100 kcal.
How many calories are in a 150 g (5.5 oz) serving of cooked kidney beans?
100 g (3.5 oz) of cooked kidney beans has 127 kcal. A typical 150 g (5.5 oz) serving has about 191 kcal. That is a low energy density.
How many grams of fiber are in a 150 g (5.5 oz) serving of cooked kidney beans?
100 g (3.5 oz) of cooked kidney beans has 7.4 g of fiber. A typical 150 g (5.5 oz) serving has about 11.1 g of fiber. They carry our “High in fiber” tag.
How filling are cooked kidney beans?
Very filling for the calories they provide: our estimated satiety score is 5 out of 5. Calculation: 1 (base) + 1 (low energy density: 127 kcal/100 g) + 1 (protein: 6.8 g/100 kcal) + 2 (fiber: 5.8 g/100 kcal) + 0 (solid food with 66.9 g of water, under 70) = 5. It is an estimate based on its composition, not a measurement in people.
Are cooked kidney beans a good choice on a GLP-1 medication?
Based on our tags, this is what matters about cooked kidney beans 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. “May cause bloating”: it can cause gas or bloating in some people, and on a GLP-1 medication that feeling can be more noticeable. These are general guidelines, not medical advice: everyone tolerates foods differently.
How many grams or ounces are in a serving of cooked kidney beans?
We use 150 g (5.5 oz) as a typical serving, about 3/4 cup. That amount provides about 191 kcal, 13 g of protein, and 11.1 g of fiber. It is a reference for calculations, not a recommendation of how much to eat.
