Fitness tips: Bushtucker trials, such as the underwater tasks, can help increase lung capacity and are great for getting the joints moving - ideal for someone who doesn't do much exercise to start burning fat fast.

Typical meal: Basic meals without oils and salt is a definite healthy option. Witchetty grubs may not be too appetising but are a great source of protein - if you can stomach them.
