Being healthy (Energy balance)

Energy balance

Energy balance is when a person balance’s energy intake with the amount of energy they release during exercise. A person is in energy balance when the amount of energy they take in as food and drink (energy input) equals the amount of energy you expend (energy output). They will neither be losing or gaining weight.


If someone eats a lot of food but does no exercise, they will gain weight. This is called positive energy balance. If someone does a lot of exercise and doesn’t eat a lot, they will lose weight. This is called negative energy balance. They will need to intake the correct amount of calories and exercise for a certain amount of time to keep the energy intake and output balanced. They will also have a balanced diet and they will get healthy. This is called neutral energy balance. This means that they are getting enough exercise for the amount of food they intake.
Positive energy balance is when the energy intake exceeds expenditure; this is when weight is gained.
Negative energy balance is less than the requirements, the additional energy required will be drawn from the body’s fat reserves therefore weight will be lost.

Positive energy balance

This is positive energy balance. This is because they are eating a lot of calorific foods but not doing any exercise. This means that they will gain weight.

Negative energy balance

This is negative energy balance. This is because he is eating a lot of healthy foods which don’t contain of many calories and he is exercising a lot. This can cause the body to lose weight.

Neutral energy balance

 



This is neutral energy balance. This is because she is eating an equal amount of nutrients in her diet and exercising enough which releases the energy that she has put into her body so that she doesn't lose or gain weight.
