Bell peppers are a staple in healthy kitchens, prized for their crunch, color, and low-calorie profile. But if you're tracking fat intake for weight management, keto, or general nutrition, you need precise numbers. This calculator converts your bell pepper serving into fat content per 100 grams, helping you log accurately whether you're meal prepping, following a recipe, or just curious about your daily macros.
Simply enter the weight of your bell pepper (or use our quick presets for common serving sizes), and the tool instantly shows total fat, saturated fat, and the percentage of your daily value. You'll also see a breakdown per 100g, making it easy to compare with other foods. Perfect for dietitians, fitness enthusiasts, and anyone who wants to keep their fat intake on target.

Step-by-step
How to Use This Tool
Enter the weight of your bell pepper in grams or ounces, then click Calculate Fat. The tool instantly shows the fat content per 100g, the total fat in your serving, saturated fat, calories from fat, and the percentage of the daily value (based on a 2,000-calorie diet). Use the quick-fill buttons for common serving sizes like 100g or one medium pepper (about 119g).
If you're tracking macros, you can also use this to compare different pepper colors — red, yellow, and orange peppers have slightly different fat values, but all are very low in fat. For precise logging, weigh your pepper before cutting off the stem and seeds.
Formula Explained
The calculation uses the USDA FoodData Central value for raw bell peppers: 0.30 g of total fat per 100 g. Saturated fat is approximately 0.05 g per 100 g. The formula is simple:
Total fat (g) = (Fat per 100g ÷ 100) × weight in grams
Calories from fat = Total fat × 9 kcal/g
% Daily Value = (Total fat ÷ 78 g) × 100
The 78 g daily value is the FDA reference for a 2,000-calorie diet. Your personal target may differ based on your calorie needs and health goals.
Worked Examples
Example 1: You eat 150 g of sliced red bell pepper in a salad.
Total fat = (0.30 ÷ 100) × 150 = 0.45 g
Calories from fat = 0.45 × 9 = 4.05 kcal
% DV = (0.45 ÷ 78) × 100 = 0.58%
Example 2: A recipe calls for 8 oz of bell pepper (about 227 g).
Total fat = (0.30 ÷ 100) × 227 = 0.68 g
That's less than 1 gram of fat — negligible for most diets.
Tips & Best Practices
- Weigh peppers raw, as cooking can concentrate or alter fat content slightly.
- If you're using oil to cook peppers, remember to add that fat separately — this tool only covers the pepper itself.
- For keto or low-fat diets, bell peppers are an excellent choice because they're almost fat-free.
- Use the % Daily Value to see how little fat peppers contribute to your daily limit.
Factors Affecting Accuracy
The fat content can vary slightly by pepper variety, ripeness, and growing conditions. The USDA value is an average for raw, all colors. Red peppers tend to be slightly sweeter and may have marginally higher fat, but the difference is under 0.1 g per 100g. For clinical or research purposes, always refer to the specific food label or a lab analysis.
Frequently Asked Questions
Are bell peppers high in fat?
No. Bell peppers contain less than 0.5 g of fat per 100 g, making them one of the lowest-fat vegetables. They're mostly water and carbohydrates (about 6 g per 100g).
Does cooking change the fat content?
Cooking itself doesn't add fat, but if you sauté or roast with oil, the added fat will increase the total. The pepper's own fat remains roughly the same.
How does this compare to other vegetables?
Most non-starchy vegetables are similarly low in fat. For example, broccoli has about 0.4 g per 100g, and carrots have 0.2 g. Bell peppers are right in line.
Can I use this for meal prep?
Absolutely. If you're prepping meals for the week, weigh your peppers once and use this calculator to log the fat for each portion. It's a quick way to keep your macros accurate.
