Lychees are a beloved tropical fruit, prized for their sweet, floral flavor and juicy texture. If you're tracking your daily fat intake for weight management, a low-fat diet, or general health, you might wonder exactly how much fat is in the lychees you eat. This calculator gives you a precise answer: it converts your lychee serving (whether measured by weight, by piece, or by cup) into grams of fat, based on the standard USDA nutritional value of about 0.44 grams of fat per 100 grams of raw lychee.
Simply enter your serving size, choose your preferred unit, and the tool instantly shows the fat content, along with a breakdown of calories from fat and the percentage of your daily fat allowance (based on a 2,000-calorie diet). Whether you're a dietitian planning meals, a fitness enthusiast counting macros, or just curious about this fruit's nutritional profile, this calculator makes it easy. It's also handy for comparing lychees to other fruits in your diet.

How to Use This Tool
Using the Lychee Fat Calculator is straightforward. Start by entering the amount of lychees you plan to eat in the first field. You can specify the amount in grams, ounces, cups (chopped), or whole medium-sized lychees. If you're not sure about the weight, the quick-fill buttons provide common serving sizes like 100 g, 1 cup, 10 pieces, or 3.5 oz. Next, optionally enter your daily fat target in grams. If you leave it blank, the calculator assumes a standard 70 g target, which aligns with a 2,000-calorie diet where about 30% of calories come from fat. Click "Calculate Fat" to see the total fat content, the calories derived from that fat, and the percentage of your daily fat target that this serving represents. The step-by-step breakdown shows exactly how the numbers were derived, making it easy to verify or learn from the calculation.
Formula Explained
The calculation relies on the USDA FoodData Central value for raw lychees, which lists approximately 0.44 grams of fat per 100 grams of fruit. To find the fat in your serving, the calculator first converts your chosen unit into grams using standard conversions: 1 ounce equals 28.3495 grams, 1 cup of chopped lychee weighs about 190 grams, and one medium lychee (with skin and seed removed) weighs roughly 10 grams. Then it applies the formula:
Fat (g) = (Serving weight in grams) × (0.44 / 100)
For example, a 150 g serving of lychees would contain 150 × 0.0044 = 0.66 g of fat. Since each gram of fat provides 9 calories, the calories from fat are 0.66 × 9 = 5.94 kcal. Finally, the percentage of your daily fat target is simply the fat grams divided by your target, multiplied by 100. This method is consistent with how nutrition labels calculate fat contributions.
Worked Examples
Example 1: You eat 1 cup of chopped lychees. Using the conversion, 1 cup = 190 g. Fat = 190 × 0.0044 = 0.836 g. Calories from fat = 0.836 × 9 = 7.52 kcal. If your daily target is 70 g, this serving provides about 1.2% of your daily fat allowance.
Example 2: You snack on 15 medium lychees. Each weighs about 10 g, so total weight = 150 g. Fat = 150 × 0.0044 = 0.66 g. Calories from fat = 5.94 kcal. Against a 70 g target, that's roughly 0.9% of your daily fat.
Example 3: You have a 3.5 oz serving. Converting to grams: 3.5 × 28.3495 = 99.2 g. Fat = 99.2 × 0.0044 = 0.436 g. Calories from fat = 3.93 kcal. This is a negligible contribution to your fat budget.
Tips & Best Practices
- For the most accurate results, weigh your lychees on a kitchen scale rather than relying on piece counts, since sizes vary significantly.
- Remember that lychees are naturally very low in fat, so the fat content is minimal. The main nutritional considerations are their sugar and carbohydrate content.
- If you're tracking macros, use this calculator alongside a carbohydrate and protein calculator to get a complete picture of your serving.
- When using canned lychees, check the label, as syrup adds sugar and may slightly alter the fat content (usually still negligible).
Factors Affecting Accuracy
The fat content of lychees can vary slightly depending on the cultivar, ripeness, and growing conditions. The USDA value of 0.44 g per 100 g is an average across samples. Fresh lychees have a higher water content, which dilutes the fat percentage, while dried lychees (lychee nuts) are much more concentrated and contain significantly more fat per gram. This calculator is intended for fresh, raw lychees. If you're using dried lychee, the fat content can be several grams per 100 g, so adjust accordingly. Also, the weight of a "medium" lychee can range from 8 to 12 grams; the calculator uses 10 g as a reasonable average.
Frequently Asked Questions
Are lychees high in fat?
No, lychees are extremely low in fat. A 100 g serving contains only about 0.44 g of fat, which is less than 1% of the recommended daily fat intake for an average adult. This makes lychees a great choice for low-fat diets.
How many calories are in lychees?
Lychees are relatively low in calories, with about 66 kcal per 100 g. The majority of these calories come from carbohydrates, primarily sugars. The fat contribution is minimal, as this calculator shows.
Can I use this calculator for canned lychees?
Yes, but be aware that canned lychees are often packed in syrup, which adds sugar and calories. The fat content remains very low, but the overall nutritional profile changes. For best accuracy, use the nutrition label on the can.
Why is the fat content so low?
Lychees are a fruit, and most fruits are naturally low in fat. The fat that is present is mostly in the seeds, which are not typically eaten. The edible flesh is composed mainly of water, carbohydrates, and small amounts of protein and fat.
