    Macro Question

    I was thinking about this the other day. Where do calories come from if theyre not from protein, fats or carbs? Take a can of tuna for example

    32g protein x 4 = 128 calories
    .5g fat x 9 = 4.5 calories
    0g carbs x 4 = 0 calories

    132.5 calories... but the can says 150

    Make sure you read the label right.

    Often it says misleading things such as the following (numbers are made up ):
    Serving size: 130g
    Servings per container: 1.5
    Calories per serving: 150
    Nutritional info per 100g:
    fat = x
    pro = y
    carbs = z

    So you see there the calories are referring to a serving whereas the macro breakdown refers to per 100g. Don't get confused between the two

    I know about that, and thats not it... Its the same with chicken, eggs, pretty much everything i look at the label for. Macros dont equal up to total calories??

    I think the FDA allows them to round the number either up or down depending on which is closer. However, 134 to 150 is quite a bit of rounding.
