What is the starvation myth?
The ‘starvation mode’ theory is when a person trying to lose weight reduces their kilojoules intake enough they actually slow down their metabolism, which prevent further weight loss from happening.
Does starvation work for weight loss?
While there is no ‘biological’ evidence to support the ‘starvation mode’ myth, there may be behavioural reasons why weight loss stops when kilojoules are severely reduced. Science shows over-restricting food or depriving ourselves from food actually makes us more likely to overeat these foods.
Slow and steady is most effective for long term sustainable weight loss
Australian Dietary guidelines as well as WW’s program guidelines, recommend a safe weight loss rate of 500g-1 kg a week. You may lose more in the first few weeks, but this should even out over time.
