What is energy balance and how does it affect the body?
Understand the Problem
The question is providing information about energy balance, which is the relationship between energy intake from food and energy expenditure by the body. It discusses sources of energy, activities that use energy, and how to determine a person's energy balance.
Answer
Energy balance is the relationship between calorie intake and expenditure, affecting weight and health.
Energy balance is the relationship between calories consumed and burned. If intake equals expenditure, weight remains stable. Positive balance (more intake) leads to weight gain, while negative balance (more expenditure) causes weight loss. It affects metabolism, body composition, and overall health.
