How to Use This Tool
Enter the amount of yam you plan to eat, select the unit (grams, ounces, or cups), and choose the preparation method (raw, boiled, or baked). The calculator uses standard nutritional data per 100 grams and scales it to your portion. You can also toggle the fiber subtraction to see net carbs, which is useful for low-carb or keto meal planning.

How It Works
The calculator uses standard USDA nutritional data for yams. For raw yam, per 100 grams: 27.9 g carbohydrates, 4.1 g fiber, and 118 calories. Boiled or baked yams have similar values, with slight calorie differences due to water loss. The tool multiplies these per-100g values by your portion size (converted to grams) to give accurate totals.
Worked Examples
Example 1: You eat 150 g of boiled yam. Total carbs = 27.9 × 1.5 = 41.9 g. Fiber = 4.1 × 1.5 = 6.2 g. Net carbs = 41.9 − 6.2 = 35.7 g. Calories = 116 × 1.5 = 174 kcal.
Example 2: You have 1 cup of cubed raw yam (about 150 g). Total carbs = 27.9 × 1.5 = 41.9 g. Net carbs = 35.7 g. Calories = 118 × 1.5 = 177 kcal.
Tips & Best Practices
- Weigh yam after peeling and trimming for the most accurate carb count.
- Boiling reduces water content, so cooked yam has slightly more carbs per gram than raw.
- If you're tracking net carbs for keto, always subtract fiber from total carbs.
- Pair yams with protein and healthy fats to balance blood sugar response.
Frequently Asked Questions
Are yams the same as sweet potatoes?
No. True yams are drier and starchier, while sweet potatoes are moist and sweeter. Nutritionally, they are similar, but yams have slightly more carbs and fiber per 100g.
Can I use this calculator for other root vegetables?
No, this tool is specific to yams. For other vegetables, use a dedicated calculator or check the USDA FoodData Central database.
Why do cooked yams have fewer calories?
Boiling can leach some water-soluble nutrients and reduce calorie density slightly, but the difference is minimal.
