How It Works

Three steps to macros
that actually work

No generic formulas. No guessing. Just a system built on real coaching experience.

01

Calculate

Enter your weight, height, age, activity level, and goals. Get personalized protein, carb, and fat targets calculated specifically for your body.

02

Plan

Choose a monthly plan that fits your budget. Get weekly macro adjustments as your body changes, meal ideas, and guidance that works with your schedule.

03

Grow

Whether you're cutting, bulking, or maintaining, your plan evolves with you. Real progress, tracked over time, with a coach who's been in your shoes.

Built by a trainer,
not an algorithm

Most macro calculators spit out the same generic numbers for everyone. FuelByButts factors in your training style, lifestyle, and where you actually are right now. Because your macros should fit your life, not the other way around.

Activity level. Body composition goals. Training volume. Dietary preferences. Sleep quality. Stress level. All accounted for.
