Final answer:
Heredity, activity level, BMI, and body composition all play a role in determining a person's weight.
Step-by-step explanation:
Factors Affecting Weight
Several factors play a role in determining a person's weight:
- Heredity: Genetics can influence body weight by determining metabolic rate, fat storage, and distribution.
- Activity Level: The amount of physical exercise and movement a person engages in can impact weight.
- Body Mass Index (BMI): BMI is a measure of body weight relative to height, which helps classify individuals as underweight, normal weight, overweight, or obese.
- Body Composition: This refers to the proportion of lean body mass (muscle, bones, organs) and fat mass in the body, which can affect weight.
