Calculate a legacy-style point value for foods using calorie, fat, and fiber inputs.
Overview
Points-based diet systems convert nutrition information into a simplified tracking number to support adherence.
This calculator uses a legacy-style formula pattern and is useful for historical plans or rough comparisons.
Steps
Collect calories, total fat, and fiber per serving.
Use per-serving calorie value.
Input total fat grams per serving.
Use capped fiber value per plan rules when applicable.
Apply points equation and round per method.
Multiply points by consumed serving count.
Math
Points (legacy style) = (calories / 50) + (fat / 12) - (fiber / 5)
The equation increases point value with calories and fat while reducing value for higher fiber, then rounds to practical tracking units.
Worked cases
Points = 180/50 + 6/12 - 4/5 = 3.6 + 0.5 - 0.8 = 3.3
Estimated points: about 3
Points = 8.4 + 1.17 - 1.6 = 7.97
Estimated points: about 8
Total points = 5 x 2
Meal total: 10 points
