Consult a Professional
Before starting any new diet, exercise, or supplementation program, especially if you are pregnant, nursing, elderly, under 18, or have any pre-existing medical condition (including but not limited to heart disease, diabetes, or an eating disorder), consult your doctor, registered dietitian, or another qualified healthcare provider.
Estimates, Not Diagnoses
Our calculators (including the Calorie, Macro, One-Rep Max, Protein, and Body Fat calculators) use general, published formulas to produce estimates. They do not account for individual medical history, medications, or conditions, and they should never be used to diagnose, treat, or manage any health condition.
