Hi & welcome!
Can you give us more information on your body type? Height/ weight/ GW? Most folks will jump on and say to cut out the nuts as they are calorie dense. That said, what do you portion sizes look like on your meals?
Are you going for a lithe body type or do you want some decent muscle mass on your frame? CrossFit is great but it adds density to female frames when they are eating lots of protein & fat.
