How does this calculator differ from the site's calorie calculator?
The calorie calculator gives you target calories with a fixed general macro split. This calculator is specific to protein and macros: it adjusts protein grams per kilogram based on your goal (higher when cutting to preserve muscle), and adds a practical meal distribution and real food equivalents.
Why does the protein target (g/kg) differ by goal?
During a calorie deficit (weight loss), the body needs relatively higher protein (2.2 g/kg) to preserve muscle mass despite the energy shortfall. When maintaining or gaining, a lower rate (1.6-2.0 g/kg) is usually enough since the body isn't in an energy deficit that threatens muscle.
Why doesn't the recommendation exceed 40g of protein per meal?
Some research suggests the body benefits from a limited amount of protein to trigger muscle building in a single meal (an effect known as the "anabolic ceiling"), so spreading protein across more meals instead of concentrating it in one or two may be more effective.
Are the food equivalents (chicken, eggs...) 100% accurate?
They're rough estimates based on known standard nutritional values (like the USDA database), varying slightly by cooking method and actual food source. Use them as a quick practical guide, not a precise milligram figure.
Can this calculator be used without a specific athletic goal?
Yes, choose "maintain weight" to get a balanced macro split for good general health, even if your goal isn't specifically building muscle or losing fat.
