What is the difference between a positive calorie balance and a negative calorie balance?
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.
What is a positive caloric balance?
A positive energy balance occurs when your energy input is greater than your energy output. That is, you eat more calories than your body uses. Your body stores excess energy or calories as fat. This results in weight gain.
What’s the difference between positive energy balance and negative energy balance?
A positive energy balance, in which energy intake exceeds expenditure causes weight gain, with 60–80 % of the resulting weight gain being attributable to body fat.
