The biggest danger with peanut butter is overeating it, as it can be hard to monitor portions when snacking on it.

For a keto-friendly peanut butter alternative, consider almond butter. At only ~3 g of net carbs in a 2 tablespoon serving, it's a way to satisfy your craving for a nut butter without taking on all the carbs.
