The three main macronutrients (also known as ‘macros’) are protein, fat, and carbohydrates. Their suggested ratio on a ketogenic diet is:
60-75% of calories from fat (or more)
15-30% of calories from protein, and
5-10% of calories from carbohydrates
While this may seem odd at first, once you get the hang of it you won't need to ‘track’ your macros as your body adjusts and you develop a feel for it. If you do decide to track your macros, think in grams and not percentages. Also, don’t stress if you’re a bit off your ideal macros. A difference of 5g of fat or protein (up or down) shouldn't put you out of ketosis as long as you keep your carbs low.
