QUICK ANSWER
How many calories are in lime?
Raw lime provides 30 kcal per 100 g. Scale from the edible portion and keep other states separate.
30 kcal / 100 gNutrition values describe a reference food state, not every individual item. Variety, water content, preparation and portion weight can change the estimate.

SERVING SIZE
Calories by portion and serving weight
Words such as “small,” “medium,” “half” and “one piece” are convenient but imprecise. Grams make the estimate reproducible, particularly when natural foods vary in size.
MACROS
Carbohydrate, protein and fat explained
Protein
0.7 g per 100 g. From Limes, raw.
Carbohydrate
10.5 g per 100 g. From Limes, raw.
Fat
0.2 g per 100 g. From Limes, raw.
MORE THAN CALORIES
Fibre, vitamins and minerals
One food does not need to provide every nutrient. These are the characteristics most useful for understanding where lime fits in a varied eating pattern.
Vitamin C
29.1 mg per 100 g in the selected USDA record.
Calcium
33 mg per 100 g in the selected USDA record.
Potassium
102 mg per 100 g in the selected USDA record.
Iron
0.6 mg per 100 g in the selected USDA record.
FOOD STATE MATTERS
How preparation changes the nutrition estimate
A reliable calorie entry should describe the food you actually ate—not merely a food with a similar name.
Raw whole fruit
Selected and only mapped lime state.
Lime juice
Use a juice entry rather than whole-fruit values.
Zest or peel
Not represented separately by the selected whole-fruit record.
Sweetened lime drink
Log sugar and all other drink ingredients.
PRACTICAL CONTEXT
How lime can fit different goals
There is no universal “good” or “bad” food. Portion, frequency, the rest of the meal, preferences and individual health needs all matter.
Portion math
At 30 kcal per 100 g, the 25 g example is 7.5 kcal.
Fibre check
The selected record lists 2.8 g fibre per 100 g.
Protein check
The selected record lists 0.7 g protein per 100 g.
Best logging move
Match whole fruit or juice correctly, then add sugar, syrup or other recipe ingredients separately.
QUALITY & SAFETY
How to choose, store and prepare it
Store
Keep whole limes in a cool, dry place or chilled.
After opening or cutting
Keep cut lime covered and chilled.
Prepare
Rinse the outside before cutting or zesting.
Safety boundary
Discard mouldy or leaking fruit; the nutrient record does not establish storage duration.
PHOTO LOGGING
How to log lime more accurately
A food photo can suggest the ingredient, but it cannot always reveal exact weight, hidden oil or preparation details. These checks turn an image guess into a better estimate.
- 01
Match the exact reference state: Limes, raw.
- 02
Use edible grams. Calories are scaled from the selected per-100-g record; named portion weights come from the same local USDA record.
- 03
Log oil, sauce, sweetener, salt and recipe ingredients separately.
- 04
Use a separate record when preparation changes the food state.

SOURCES & METHOD
Where these numbers come from
Limes, raw, per 100 g edible portion. Numeric nutrition and named-portion claims use the selected local USDA record. Preparation notes cover the common USDA forms of this food. The nutrient record does not establish storage duration, clinical advice or food-safety limits; use package directions and current authoritative guidance where relevant.
