Body Mass Index (BMI) is an indicator used to measure the relationship between a person's weight and height. The BMI formula calculates by dividing a person's weight (in kilograms) by the square of their height (in meters). Typically, BMI is used to assess whether a person is underweight, normal weight, overweight, or obese.

Body fat percentage is the percentage of body fat compared to total body weight. It reflects how much body fat one has and is commonly used to assess obesity. However, body fat percentage is not a fixed value and can vary depending on factors such as diet and exercise habits.

Basal Metabolic Rate (BMR) refers to the minimum amount of energy expenditure required to maintain basic physiological functions of the body at rest. BMR calculations exclude any activity or digestive processes, focusing solely on the minimal energy required to sustain life.

Total Daily Energy Expenditure (TDEE) is the total amount of calories your body needs to maintain your current weight based on your activity level. It includes your Basal Metabolic Rate (BMR), the energy used for digestion (Thermic Effect of Food), and the calories burned through physical activities.
