Work out keto macros instantly with clear inputs, formula shown and shareable results.
Fixes carbohydrate and protein targets first, then assigns the remaining energy to fat, which is how ketogenic macros are constructed.
Ketogenic macros
Fat grams = (total energy - carbohydrate grams x 4 - protein grams x 4) / 9

Usually 20 to 50 g a day to sustain nutritional ketosis, with individual thresholds varying.
Very high protein intakes can blunt ketosis through gluconeogenesis, though the effect is smaller than often claimed.
