Frequently Asked Questions
Why anchor macros on grams of protein per kg of body weight?
Sports nutrition research supports 1.6 to 2.2 g of protein per kg of body weight to preserve lean mass during fat loss or hypertrophy, rather than fixed calorie percentages.
How is weekly protein grocery cost estimated?
Multiplying your daily protein target by 7 days and dividing by 100 gives how many 100g protein units you consume weekly, multiplied by your blended cost per 100g protein.
