Maintaining a healthy weight using the energy balance equation
The energy balance equation is the relationship between the energy consumed – measured in The units of energy contained in food and drink. and the energy To use up or consume. – also measured in calories. Maintaining a healthy weight requires a balance between energy in and energy out. Too much energy in or too little energy out leads to excess energy being stored as fat. Too little energy in or too much energy out leads to weight loss.
Energy in and energy out do not have to balance every day. The energy equation needs to balance over time for people to maintain a healthy weight.
Understanding food – knowing what makes a healthy diet – helps people to manage the energy balance, and people's levels of physical activity are as important to the energy balance as their diet.
