A typical 150 g (5.5 oz, about 1 cup) serving provides about 75 kcal, 0.8 g of protein, and 2.1 g of fiber.

The typical serving (150 g (5.5 oz, about 1 cup)) is a common amount used for the math, not a recommendation. Ounces and cups are rounded US equivalents; the values come from the database entry cited in the sources.

What it is and how to eat it

Pineapple (Ananas comosus) is called piña in most Spanish-speaking countries and ananá in Argentina, Uruguay and Paraguay, and it is sold whole, peeled and cut, canned in juice or in syrup, and as juice. The yellow flesh is eaten, and the harder, more fibrous central core is usually removed. This page covers fresh pineapple, with 50 kcal, 9.85 g of sugars, 1.4 g of fiber and 47.8 mg of vitamin C per 100 g according to USDA.

A 150 g (5.3 oz) serving provides 75 kcal, 14.8 g of sugars, 2.1 g of fiber and barely 0.8 g of protein, so it is not the protein part the 2025 nutrition advisory on GLP-1 therapy suggests eating first; paired with a high-protein dairy food you get both, as in the cottage cheese with pineapple. It is low in fat and fiber, which fits the same advisory's advice to avoid very fatty and very high-fiber foods in the first few days of treatment. It is acidic, and reflux is common with semaglutide (Wegovy) in its 68-week trials, according to its label; if you notice heartburn after eating it, try half a serving.

What the evidence says

The EU register lists as non-authorized the assessed claims that credited pineapple or bromelain, the plant's mix of enzymes, with aiding digestion, reducing localized fat or improving circulation, and the EU has not authorized any health claim about digestion for either pineapple or bromelain. What it does have is vitamin C: with 47.8 mg per 100 g it exceeds the 24 mg the EU requires for a "high vitamin C" claim, and the 150 g serving provides 71.7 mg, 90% of the 80 mg reference value, so it could carry the authorized claim "vitamin C contributes to the normal function of the immune system" (Regulations (EC) No 1924/2006, (EU) No 1169/2011 and (EU) No 432/2012). Pineapple canned in juice has 60 kcal and 14.4 g of sugars per 100 g, counting the liquid, according to USDA, and the sugars in that juice count as free sugars under WHO's 2015 guideline, which recommends keeping them below 10% of energy; those in whole fresh fruit do not.

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.

What to keep in mind on a GLP-1 medication

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.
Hydrating
It has 85 g of water or more per 100 g, so it contributes to hydration. That helps because with a smaller appetite people also tend to eat and drink less, and not drinking enough can make constipation worse.

Frequently asked questions about pineapple

How much protein does a 150 g (5.5 oz) serving of pineapple have?

100 g (3.5 oz) of pineapple has 0.5 g of protein. A typical 150 g (5.5 oz) serving has about 0.8 g of protein. That is 1.1 g of protein per 100 kcal.

How many calories are in a 150 g (5.5 oz) serving of pineapple?

100 g (3.5 oz) of pineapple has 50 kcal. A typical 150 g (5.5 oz) serving has about 75 kcal. That is a very low energy density.

How many grams of fiber are in a 150 g (5.5 oz) serving of pineapple?

100 g (3.5 oz) of pineapple has 1.4 g of fiber. A typical 150 g (5.5 oz) serving has about 2.1 g of fiber.

How filling is pineapple?

Very filling for the calories it provides: our estimated satiety score is 5 out of 5. Calculation: 1 (base) + 2 (very low energy density: 50 kcal/100 g) + 0 (protein: 1.1 g/100 kcal) + 1 (fiber: 2.8 g/100 kcal) + 1 (solid food with 86.0 g of water) = 5. It is an estimate based on its composition, not a measurement in people.

Is pineapple a good choice on a GLP-1 medication?

Based on our tags, this is what matters about pineapple on a GLP-1 medication. “Low energy density”: plenty of volume for few calories; make sure it does not push protein foods off your plate. “Hydrating”: a lot of water, which contributes to hydration when you eat and drink less. These are general guidelines, not medical advice: everyone tolerates foods differently.

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

We use 150 g (5.5 oz) as a typical serving, about 1 cup. That amount provides about 75 kcal, 0.8 g of protein, and 2.1 g of fiber. It is a reference for calculations, not a recommendation of how much to eat.
