OurFit is a general fitness tool, not medical advice. Daily targets are estimates from published equations and sports-nutrition guidance. They are not a prescription. Talk to a qualified clinician or registered dietitian before changing how you eat, especially if you have a medical condition.

Mifflin�St Jeor (resting calories)

Daily calorie targets start from the Mifflin�St Jeor equation for resting energy expenditure (Am J Clin Nutr, 1990).

Activity multipliers (TDEE)

Activity level multiplies resting calories using the FAO/WHO/UNU human energy-requirement factors.
