Our Methodology
Our calculators use established, widely cited methods. Basal metabolic rate is estimated with the Mifflin-St Jeor equation, activity levels use standard multipliers, and macro splits follow the conventional energy values of 4 calories per gram of protein, 4 per gram of carbohydrate, and 9 per gram of fat. These are respected starting points used across fitness and nutrition practice, but they are still estimates. Individual needs vary, and our results are no substitute for professional advice.
Who We Are
We are a small independent team focused on building useful fitness tools. We do not sell supplements, meal plans, or coaching, and we have no products to push. Our goal is straightforward: give you accurate, easy-to-use calculators and honest guides, supported by advertising, so the tools stay free for everyone.
A Quick Note
The numbers our calculators produce are estimates for informational purposes. If you have a medical condition or specific health goals, talk to a qualified professional before acting on them.
