You need My Fitness Pal Premium to change your macros. I recommend spending the money for the year.
If you prefer not to upgrade to Premium, it’s super helpful if you memorize what numbers I gave you. Just try to hit them even though your Nutrition Goals will show something slightly different.
Then, when you screenshot your Nutrition page and send it to me, please type in below what your actual goals are. For example, MFP might only let you do 200 carbs, 150 protein and 67 fat, but your goal is 204 protein, 152 carbs and 68 fat. Text that as a reminder to me with your nutrition screenshot.
Upgrade to Premium.
