Detailed explanation-1: -Energy is another word for “calories.” Your energy balance is the balance of calories consumed through eating and drinking compared to calories burned through physical activity. What you eat and drink is ENERGY IN. What you burn through physical activity is ENERGY OUT.

Detailed explanation-2: -Positive energy balance occurs when energy intake is greater than energy expenditure, usually resulting in weight gain. Negative energy balance is when energy intake is less than energy expenditure, usually resulting in weight loss. Energy intake is made up of the calories we consume from food and beverages.

Detailed explanation-3: -You gain weight when you eat more calories than you burn-or burn fewer calories than you eat. Some people seem to lose weight more quickly and more easily than others. But everyone loses weight by burning more calories than are eaten. The bottom line is calories count.
