How does butter fit your goals?

Most of the calories in butter come from fat (11.4g per 1 tbsp (14g)), which makes it calorie-dense — easy to under-portion if you're eyeballing. Dietary fat is essential for hormone production and absorbing fat-soluble vitamins, but at 9 calories per gram it's also the macro most people accidentally over-consume when they stop weighing portions.

Diet-wise, butter fits keto, low-carb, and vegan and vegetarian eating patterns.
