A typical 40 g (1.5 oz) serving provides about 39 kcal, 0.9 g of protein, and 4.2 g of fiber.

The typical serving (40 g (1.5 oz)) 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

The Dictionary of the Spanish Language defines maracuyá (passion fruit) as the edible fruit of the passionflower, roundish and yellow or purple, and records parchita in Venezuela; the Diccionario de americanismos records parchita in the Dominican Republic and Venezuela, chinola in the Dominican Republic and Colombia, and parcha in Puerto Rico. Inside it has many small seeds wrapped in a mucilaginous, sweet-sour pulp, which is used to make drinks. This page covers raw purple passion fruit according to USDA, with 97 kcal, 10.4 g of fiber, 11.2 g of sugars and 30 mg of vitamin C per 100 g of edible portion.

The pulp of one fruit weighs about 18 g (0.6 oz) according to USDA and provides 17 kcal, 1.9 g of fiber and 2 g of sugars, so the pulp of two fruits over plain yogurt or whipped fresh cheese gives a lot of flavor with little energy and adds the protein of the dairy. The 2025 nutrition advisory on GLP-1 therapy lists fruit among the foods to encourage, but suggests avoiding fatty or high-fiber foods in the first days of treatment and, for constipation, increasing fiber gradually. With its seeds it is very high in fiber for its size, so in those days starting with the pulp of half a fruit may sit better; it is also acidic, something to keep in mind if you get heartburn.

What the evidence says

Raw purple passion fruit juice has 0.2 g of fiber and 13.4 g of sugars per 100 g, against 10.4 g of fiber in the fruit, according to USDA, and the sugars in the juice count as free sugars under WHO's 2015 guideline, which recommends keeping them below 10% of energy; those in the whole fruit do not. With 10.4 g of fiber per 100 g, the fruit meets the 6 g minimum for a "high fibre" claim. With USDA's figures, its 30 mg of vitamin C per 100 g exceed the 24 mg the EU requires for a "high vitamin C" claim, so it could carry the authorized claim "vitamin C contributes to the normal function of the immune system", but the pulp of one fruit provides 5.4 mg, 7% of the 80 mg reference value (Regulations (EC) No 1924/2006, (EU) No 1169/2011 and (EU) No 432/2012). The EU register holds no health claim about passion fruit, either authorized or rejected.

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

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.
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.

Frequently asked questions about passion fruit

How much protein does two passion fruits have?

Two passion fruits, our reference serving of 40 g (1.5 oz), has about 0.9 g of protein. 100 g (3.5 oz) of passion fruit has 2.2 g of protein. That is 2.3 g of protein per 100 kcal.

Two passion fruits, our reference serving of 40 g (1.5 oz), has about 4.2 g of fiber. 100 g (3.5 oz) of passion fruit has 10.4 g of fiber. It carries our “High in fiber” tag.

How filling is passion fruit?

Very filling for the calories it provides: our estimated satiety score is 5 out of 5. Calculation: 1 (base) + 1 (low energy density: 97 kcal/100 g) + 0 (protein: 2.3 g/100 kcal) + 2 (fiber: 10.7 g/100 kcal) + 1 (solid food with 72.9 g of water) = 5. It is an estimate based on its composition, not a measurement in people.

Is passion fruit a good choice on a GLP-1 medication?

Based on our tags, this is what matters about passion fruit 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. “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 passion fruit?

We use 40 g (1.5 oz) as a typical serving, roughly two passion fruits. That amount provides about 39 kcal, 0.9 g of protein, and 4.2 g of fiber. It is a reference for calculations, not a recommendation of how much to eat.
