Fueli builds a muscle-gain meal plan around a calorie surplus and a protein target high enough to support growth, then generates meals to hit both — every single day.
To use Fueli for muscle gain: set a calorie goal above your maintenance level (Fueli's built-in calculator can estimate this for you) and a protein target sized for muscle growth, then let Fueli generate meals built to land within ±50 kcal of that goal per meal, every meal.
Fueli includes a built-in calorie calculator — enter your age, height, weight, gender, and activity level, and it estimates your BMR and TDEE, then suggests a calorie target for a build-muscle goal specifically (a surplus above maintenance), which you can adjust before applying it.
You set a protein goal in grams alongside your calorie goal, and every generated meal is built to hit both at once — so a surplus of the wrong calories (all carbs, no protein) is never the outcome.
A higher calorie and protein target does not mean harder recipes or a bigger grocery bill than you asked for — Fueli still respects the cooking skill level and budget you set when generating meals.
If you're cooking for a household, Fueli's household size setting scales ingredient quantities across the plan and grocery list, so a surplus built for one person doesn't have to be recalculated by hand for the whole table.
Fueli's built-in calorie calculator estimates your BMR and TDEE from your age, height, weight, gender, and activity level, then suggests a calorie target for a build-muscle goal specifically. You can adjust the number before applying it.
Yes — protein is set in grams as its own goal, independent of your calorie target, and every generated meal aims to hit both.
No — your budget and cooking skill settings still apply. A muscle-gain calorie target changes portion sizes and meal composition, not the complexity or cost tier of recipes.
