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.
Protein per kilogram
Protein targets follow the International Society of Sports Nutrition position stand on protein and exercise (1.4�2.2 g/kg).
Fat and remaining carbs
Fat is set near the Dietary Guidelines for Americans acceptable macronutrient range; carbs fill the remaining calories.
Food calorie values
Logged foods use typical values aligned with USDA FoodData Central.
