MainGain - Your Maintenance Calculator

Finding your maintenance calories shouldn't be complicated. MainGain removes the guesswork with a scientifically-proven 14-day tracking approach.

WHAT IS MAINTENANCE?
Your maintenance calories are the exact amount you need to eat to maintain your current weight. It's the foundation for any fitness goal - whether you want to bulk, cut, or recomp.

WHY 14 DAYS?
Your daily weight fluctuates 2-4 lbs from water, sodium, and meal timing. Traditional calculators guess based on averages. MainGain uses your actual data to find YOUR unique
maintenance calories.
