Nutrition values
Short explanations, formulas, examples and limitations.
Nutrition: protein, fat and carbohydratesNutrition shows the listed protein, fat and carbs for a food. FATSLIM normally presents these values per 100 g so foods can be compared on the same scale.OpenCalories per 100 gCalories per 100 g show the energy value on a consistent weight basis. This makes foods with different serving sizes easier to compare.OpenProtein per 100 gProtein per 100 g shows the amount of protein in a standard serving weight. FATSLIM uses this value in food cards, rankings, comparisons and calculated price per 10 g of protein.OpenFat and saturated fat per 100 gFat and saturated fat per 100 g are separate nutrition values that describe a food. They support neutral comparisons in cards and tables.Open
Price metrics
Short explanations, formulas, examples and limitations.
Price per 100 gPrice per 100 g normalizes a food price by weight, making foods with different units and price rows easier to compare.OpenCalculated cost per 100 kcalCalculated cost per 100 kcal combines food price and calories per 100 g to compare the calculated cost of the same amount of energy.OpenPrice per 10 g proteinPrice per 10 g of protein combines a food price with protein per 100 g. FATSLIM shows no Result when protein is missing or zero.OpenCalculated metrics FATSLIMCalculated metrics normalize price, weight, calories, protein and baskets for comparison. They are not market claims or recommendations.Open
How FATSLIM pages work
Short explanations, formulas, examples and limitations.
How a food card worksA food card combines its name, city, nutrition, price rows, related rankings, comparisons and methodology notes.OpenHow a city food page worksA city food page shows available city row, prices metrics, comparison with other cities and links to related foods.OpenHow it works rankings FATSLIMRankings sort foods by a selected metric such as protein, calories or calculated price. They organize data and until not recommend a food.OpenHow food comparisons workA comparison shows two foods side by side with nutrition, price and calculated values. The text remains neutral and explains numeric differences.OpenHow to read food basketsA basket is a set of foods with quantities and city-based calculations. FATSLIM shows total cost, calories, protein, coverage and missing rows.Open
Data and limitations
Short explanations, formulas, examples and limitations.
Data sources FATSLIMFATSLIM separates nutrition rows, price rows and calculated values. Coverage varies, so limitations are shown beside calculations.OpenData limitationsData limitations explain why a row may be empty, rounded or different from another source. FATSLIM does not fill gaps with estimates.OpenWhy values may differValues may differ by brand, processing, raw or cooked state, measurement unit, rounding and source.OpenWhat FATSLIM does not claimFATSLIM shows reference values and available price rows. It does not verify a specific store price, make medical claims or rate a food as suitable for everyone.Open
