1989 Fat Finder Wheel‎ Fat & Calorie Calculator NOS Healthy Habit Packaging Fair

1989 Fat Finder Wheel Fat & Calorie Calculator NOS Healthy Habit Packaging Fair. The Fat Finder is a circular slide chart designed to calculate the percentage of fat calories in food. To use it, align the number of total calories on the outer ring with the grams of fat on the inner ring. The percentage of fat calories will then appear in the window at the top of the chart. For example, if a food item has 200 calories and 10 grams of fat, aligning 200 with 10 will show 45% fat calories in the window.
