I eat about three-four whole lettuces per day with a lot of other veggies and nothing happens. im always the same! and im very slim. sooo live your life with lettuce, trust me its almost as if it has no calories at all

my doc says that I can eat all the lettuce that I want, its what I put on it that makes me gain. he says “eat yourself silly” with fresh vegetables. I do, and love the salad spritzers which are like 1 or 2 calories per spray. it gives it a little flavor anyway.

almost zero calories. so eat as much as you want!
