Learn how BMI, calorie intake, TDEE and healthy habits work together to support weight loss, muscle gain and long-term health.
BMI (Body Mass Index) is a simple calculation based on height and weight that helps estimate whether a person is underweight, healthy, overweight or obese.
Calories are units of energy your body uses for movement, exercise and basic body functions like breathing and digestion.
TDEE (Total Daily Energy Expenditure) estimates how many calories your body burns daily, including workouts and daily activity.
Sustainable habits usually produce better long-term results than short-term extremes.
BMI is useful for general health screening, but it does not measure muscle mass or body fat directly.
Daily calorie needs vary based on age, gender, body size and activity level.
A balanced calorie deficit combined with exercise, sleep and healthy nutrition is usually most effective.
