For the best keto macros, choose a whey protein isolate or another keto-specific protein powder with little to no added carbs and no sugar. Natural almond butter with oil separation works best because its looser texture helps bind the dough without added liquid. Taste the dough before rolling and adjust sweetness with additional powdered sweetener if needed, remembering that cold foods taste slightly less sweet once chilled. To keep net carbs very low, use sugar-free chocolate chips sweetened with erythritol or stevia and avoid high-carb add-ins like dried fruit or regular chocolate. These protein balls are perfect for meal prep, and you can store them in the freezer in a single layer until solid, then transfer to a bag or container for easy grab-and-go snacking.
