Clinical Guidance

BMI is a screening measure of body size, not a direct measure of body fat. The standard WHO categories are underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), and obese (≥30).

BMI can overestimate body fat in athletes with high muscle mass and underestimate it in older adults with low muscle mass. Interpret it alongside waist circumference and clinical context rather than as a standalone diagnosis.

How It Works

Calculate carbohydrate, protein, and fat targets for endurance athletes based on training volume, intensity, and race fueling demands

Each component has a specific meaning:

  • Training volume — The training volume recorded for the scenario being assessed.
  • Intensity — The intensity recorded for the scenario being assessed.
  • Race fueling demands — The race fueling demands recorded for the scenario being assessed.

Note: Interpret the endurance macro split result against the thresholds and context described above.

How to Use

Enter the training volume, intensity, race fueling demands for the scenario you are assessing. Calculate carbohydrate, protein, and fat targets for endurance athletes based on training volume, intensity, and race fueling demands. Use the endurance macro split result to inform your calculation.
