Meal ideas & pairings
Two tablespoons of peanut butter is roughly 190 calories — protein-rich for a plant food, but calorie-dense enough to sabotage a deficit if spooned blind. Measure it, then spread it on apple or celery so the snack has volume. Natural versions separate; stir once and keep refrigerated.
