Does It Work?
Favoured by the likes of Kim Kardashian and Gwyneth Paltrow for its rapid results, the Ketogenic Diet has been making headlines non-stop over the past 12 months.
The low carbohydrate, high fat program sees participants eat moderate protein and receive the majority of their energy intake from fat.
But does it really work?
The Dietitians Association of Australia recently weighed in on the controversial diet and revealed the three things people need to consider before jumping on board the Keto bandwagon.
In a recent media alert, the DAA first explained the thinking behind the program and how it works.

‘As fat is the main source of energy being consumed, the body must then use this (that is, break it down) as its main energy source or “fuel”,’ they explained.
’When dietary fat is metabolised for energy, by-products called “ketone bodies” (molecules that are made by the liver from fatty acids) are produced which are used up by the body’s tissues, muscles and the brain. This process is known as “ketosis”.
‘The body can enter ketosis during times of severe energy restriction (such as during fasting or starvation) or prolonged intense exercise, or when carbohydrate intake is reduced to around 50g per day, or less – the equivalent of around two slices of bread, and a banana.’
While there are many low carb, high fat diets available, the Keto Diet remains ‘proportionately lower in carbohydrates’ at around 20 to 50 grams per day to keep the body ‘in a state of ketosis’.
When it comes to weight loss, the DAA says those who follow a Keto Diet will ‘undoubtedly result in short-term weight loss’.
This, they explain, probably comes down to ‘a reduction in total energy (kilojoule) intake, the depletion of liver and muscle glycogen stores and associated water, and a reduced appetite’.
