We aim for a fat percentage of 25% or less with our food choices. To figure out the percentage of an item, 1 gm of fat = 9 calories. Fat grams are listed on the back of each product in the ingredient breakdown. Multiply fat grams by 9. This will give you total calories of fat. To figure out the percentage, divide the fat calories into the total calories and multiply by 100. The result should not exceed 25%. A common point of confusion with some of our clients is with the term “zero trans fat” displayed on food packaging. Companies prominently display this phrase in the hope of misleading the consumer. Trans fats are chemically modified fats that solidify at room temperature such as margarine and shortening. Just because a product is trans fat free does not mean it it fat free.
