Note: The editing of the macros is a Premium function
Please go to either the Diary or the Progress tab on the bottom of the app, then tap on the Profile icon in the top right corner. Then press Adjust macronutrients.

Adjust nutrition settings per wish either by moving the slider or clicking on "-" and "+" left and right to the slide and tap on Save when you're done. Note that the sum of the macros has to add up to 100% of your calorie goal, it cannot be more or less than that.
The macros for the keto diets are freely adjustable except for the carbs. The percentage for the carbs is locked as we otherwise do not have any technical solution to allot matching recipes.
You can choose between three plans either offering 20, 50 or 100 grams of carbs (Ketogenic Easy, Ketogenic Medium, Ketogenic Strict) - but you are able to manually change fat and protein.
