Measure it

Peanut butter is one of the foods people most often under-count, because a spoonful straight from the jar is usually heaped. If you are tracking, weigh it a few times so you know what your usual spoonful really is.

Protein in peanut butter

Peanut butter has about 4 g of protein per tablespoon, but four times as many calories from fat. It is a useful extra, not a main protein source.
