How to use Macro Calculator

- Pick activity and goalChoose how active you are and whether to lose, keep or gain weight.

The macro split is set to higher protein: 30% of calories from protein, 40% from carbohydrates and 30% from fat. Type your details and goal, and the grams of each appear under the result. Protein and carbs have 4 calories a gram and fat 9.
How it works
Macro Calculator is a web page that does its work on your own device. Everything you type or choose is worked out by your browser and never sent to a server, so nothing is stored and there is nothing to delete. There is no account, no sign-up and no limit on how often you use it.
Hitting your macros
Protein is the one most people fall short on. Spread it over three or four meals; the fat and carb numbers matter less day to day than the calorie total.
