Okay.. so this is a super weird question but I'm confused. If the package of some powdered peanut butter says 45 calories per 2 tbsp., but the directions are to mix 2 tbsp powder with 1 tbsp water, then is it 45 calories per 2 tbsp. of the powder on its own or 45 calories per 2 tbsp. of the mixture of powder combined with the water?

    12g of powdered Pb is 45 cals.... Weigh it out, then add the water.

    I’ve used PB2, Jif peanut powder, and Crazy Richard’s... all use tablespoons of their powders “dry” in their nutritionals. All are pretty close but there are small differences (PB2 adds a sweetener, etc.).

    Yes, but adding the water would increase the volume, so less peanut powder is in 2 tablespoons when mixed with water.

    You still have the same amount of PB powder. If you take 1 piece of spaghetti and break it in half, do you have twice as much?

    Weigh the dry PB2. Add to log. Add the recommended ratio of water.. if you're doing that. I often use it in smoothies and soups without adding water explicitly.

    What? That is not a good metaphor... a tablespoon is a measure of volume. Water has volume, the peanut powder has volume. So, when the peanut powder is mixed with water the zero calorie water takes up some of the space reducing the overall calories (etc.) in the total volume if it was just the powder alone.

    but adding something with 0 calories cannot increase the calories...

    All that being said, it's a moot point...

    I looked again and the nutrition labels don't specifically say "dry" but they also don't say mixed with water. So, by default, the nutrition information is for the ingredient as-is (i.e. "dry").

    VOLUME...

    The question was whether to measure the powder dry or after you re-hydrate it (mix it with water). So, adding something with zero calories can decrease the amount of calories in the same volume being measured - there is less powder in that same tablespoon after you have mixed it with water.

    Water has no calories. You could add 2 tbsp to a gallon and it would still only be 45 calories.

    1/4 cup of generic apple juice has 28 calories. Now, mix that 1/4 cup of apple juice with 1/4 cup of water. How many calories would now be in 1/4 cup of the mixed solution?

    Answer: half (14 calories)

    Math is hard :D
