Health comparisons

27 side-by-side guides to the health calculators — what each one measures, how they differ, and when to reach for which.

These comparisons sort the health calculators into pairs that answer closely related questions: body-composition estimates like BMI, body fat, waist-to-height ratio, and lean body mass; energy-balance tools like BMR, TDEE, calorie deficit, and macros; and screening measures such as blood pressure, blood sugar, and blood-chemistry ratios. Fitness pages put timed tests like the six-minute walk and VO2max estimates next to strength measures like one-rep max and vertical jump. Each page is clear about what the calculators can and cannot show — an estimate, not a diagnosis.
