Understanding Your Fitness Metrics

• Body Mass Index (BMI): A standard calculation comparing height to weight, categorizing individuals into underweight, normal weight, overweight, or obese.
• Basal Metabolic Rate (BMR): The baseline number of calories your body burns at complete rest to maintain vital functions.
• Total Daily Energy Expenditure (TDEE): The total calories you burn per day based on your BMR and physical activity level. This is the starting point for active weight loss, maintenance, or muscle gain diets.
• Hydration Guidance: An estimate of daily water needs based on body mass and baseline physical requirements.
