WW vs. Intermittent Fasting

Compare the fasting diet with with the WW (Weight Watchers reimagined) weight loss program. We'll look at what you'll eat, the health risks and liveability of both options.

Does fasting work for weight loss?


There are a few different methods for following an intermittent fasting diet, including 5:2 diet: consuming a quarter of what you’d normally eat for two days a week then eating whatever you like for the other five; time-restricted fasting such as 16:8 where there’s an ‘eating window’ of 8 hours and fasting for the other 16. Other variations including of fasting on alternate days or eating one meal per day.

According to research released at the end of last year, while intermittent fasting can help people lose weight, it’s no more effective than traditional weight-loss diets. Plus, research shows a significant proportion of people struggle to stick with fasting long term.

The focus of most intermittent fasting techniques is on when and how much to eat, rather than the quality of food choices. As well as restricting your lifestyle, this may also increase the risk of eating a poorly balanced diet and making less-healthy choices during non-fasting periods.

Intermittent fasting involves moving between cycles of fasting or a limited kilojoule intake and unrestricted eating. The timeframe of the fast is dependent on the particular diet you’re following. This means that you are restricted to not eating any food, or eating very little during fasting periods.



Beyond more flexibility in your food choices, WW's program also helps you fit in more movement and teaches you healthy habits that can shift your mindset. With an approach that goes beyond eating, you’ll see benefits both on and off the scale.
Due to its restrictive nature, intermittent fasting isn’t sustainable long-term for most people. It can be challenging to coordinate fasting around eating out and celebrations with friends and family.


Health risks

WW is the #1 doctor recommended weight-loss program according to an August 2016 survey of primary care physicians.
The Dietitians Association of Australia expresses concern about the diet’s focus on the quantity of food eaten rather than the quality. While you may be hitting your kilojoule target, you may not actually be meeting your required daily nutrient intake – something that could seriously affect your health in the long run.
