Example result
kcal per 100 g
This is a sample only. Use your own stats and compare the result with your weekly trend.
Use the complete recipe, package, or meal values and keep the serving definition consistent. Include oils, drinks, sauces, and toppings when they are part of the total, then divide or compare using the same units.
kcal per 100 g is an estimate for meal planning and food logging. Brand, preparation method, portion size, and measurement accuracy can change the real value.
Do not mix cooked and uncooked weights or omit ingredients that contribute meaningful calories. A serving count is only useful when each serving is portioned consistently.
Update the total when ingredients or portions change. If precision matters, weigh the finished food and divide it into equal gram or ounce portions.
Save the ingredient totals, finished weight, serving count, and the portion you actually ate so the estimate can be reproduced later.
