Need a reason to add more nuts to your diet? Nuts are good sources of fat and protein – two macronutrients that are essential on the keto diet. Nuts also serve up plenty of vitamins and minerals, which makes nuts a healthy snack option. Not all nuts contain the same amount of carbohydrates, so choose your snack wisely. Pili nuts (a buttery nut from the Philippines), pecans, brazil nuts are some of the most keto-friendly nut options.
