05.Energy and exercise
Ultimately, protein products are a source of energy, which you’ll need to burn off if you want to avoid putting on weight.
For example:
- An average woman (weighing about 65 kg) would need to put in around half an hour of light running to burn off an AUSSIE BODIES Protein Revival Drink
- An average man (weighing about 80 kg) would need to spend slightly longer than that on a rowing machine to use up the kilojoules consumed in a MUSASHI P40 Protein Bar.
The table below gives an estimate of the total kilojoules used over 30 minutes by an average man and woman for different activities.

To calculate the kilojoules used per 30 minutes of exercise for your own body weight, multiply the kJ/kg figure by your body weight in kilograms.
