A typical 30 g (1 oz) serving provides about 9 kcal, 0.2 g of protein, and 0.8 g of fiber.

The typical serving (30 g (1 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 lime is a green citrus fruit, smaller and more aromatic than the lemon: the most widely sold is the Persian or Tahiti lime (Citrus latifolia), which is seedless, and the Mexican lime (Citrus aurantiifolia) is smaller and has seeds. It is called lima in Spain and Argentina, while in Mexico and Central America it is the everyday limón, or limón verde, and in Colombia it is sold as limón Tahití. This page covers raw lime, with 30 kcal, 2.8 g of fiber and 29.1 mg of vitamin C per 100 g according to USDA.

A 30 g (1.1 oz) serving, less than half a lime, provides 9 kcal and 0.8 g of fiber: like lemon, it is there for flavor, and its juice goes with protein in dishes such as the Yucatán-style lime soup with chicken and jicama, the Mexican-style tuna tostadas or the nopales salad with black beans and queso fresco. The 2025 nutrition advisory on GLP-1 therapy suggests starting with protein and avoiding sugar-sweetened beverages, so sugared agua de limón or limeade is not the best way to have it. The US National Institutes of Health include citrus among the acidic foods that can make reflux worse, which is common with these medications according to the Wegovy label; if you get heartburn in the first few days of treatment or after a dose increase, try using less.

What the evidence says

With 29.1 mg of vitamin C per 100 g, just over half the amount in lemon flesh (53 mg), lime just clears the 24 mg the EU requires for a "high vitamin C" claim and could carry the authorized claim "vitamin C contributes to the normal function of the immune system" (Regulations (EC) No 1924/2006 and (EU) No 432/2012). In practice it provides little: 8.7 mg in the 30 g serving and 13.2 mg in the juice of one lime, about 44 g according to USDA, 11% and 17% of the EU's 80 mg reference value (Regulation (EU) No 1169/2011). The sugar added to agua de limón or limeade counts as free sugar for WHO, which recommends keeping free sugars below 10% of daily energy. The EU register lists no health claim for lime.

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 lime

How much protein does a 30 g (1 oz) serving of lime have?

100 g (3.5 oz) of lime has 0.7 g of protein. A typical 30 g (1 oz) serving has about 0.2 g of protein. That is 2.3 g of protein per 100 kcal.

How many calories are in a 30 g (1 oz) serving of lime?

100 g (3.5 oz) of lime has 30 kcal. A typical 30 g (1 oz) serving has about 9 kcal. That is a very low energy density.

How many grams of fiber are in a 30 g (1 oz) serving of lime?

100 g (3.5 oz) of lime has 2.8 g of fiber. A typical 30 g (1 oz) serving has about 0.8 g of fiber.

How filling is lime?

Very filling for the calories it provides: our estimated satiety score is 5 out of 5. Calculation: 1 (base) + 2 (very low energy density: 30 kcal/100 g) + 0 (protein: 2.3 g/100 kcal) + 2 (fiber: 9.3 g/100 kcal) + 1 (solid food with 88.3 g of water) = 6; capped at 5. It is an estimate based on its composition, not a measurement in people.

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

Based on our tags, this is what matters about lime 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 lime?

We use 30 g (1 oz) as a typical serving. That amount provides about 9 kcal, 0.2 g of protein, and 0.8 g of fiber. It is a reference for calculations, not a recommendation of how much to eat.
