diet and exercise

lifestyle- the amount of activity you do affects how much you should eat. e.g. an officer worker will need less food than a builder who will need more energy 

age- when you're young,you're growing and active and so you eat a lot. adults have stopped growing and are normally less active. 

size and sex- the bigger you are the more food the body needs. men are usually bigger and have more muscle than women so they need to eat more. 

BMR stands for Basic Metabolic Rate; the number of kilojoules you use to stay alive each day.

PAL stands for Physical Activity Level; the number of kilojoules you use to fuel all of your physical activity.

BMR + PAL = your daily energy requirement.
