What is the 80/20 rule diet?
Long-term weight loss is challenging and associated with a high risk of failure. The 80/20 rule diet recognises that many of us find sticking to a diet unrealistic and impossible to stick to. The 80/20 rule diet encourages followers to eat a healthy, balanced diet designed to meet their goals for 80 per cent of the time while allowing them to enjoy some of their favourite foods, in moderation, for the remaining 20 per cent.
How does the 80/20 rule diet work?
Followers adopt a healthy eating plan for 80 per cent of the time which addresses personal nutritional needs and meet nutritional guidelines. These include eating five portions of fruit and vegetables a day, eating more wholegrains, enjoying fish, poultry, beans and less red meat, and opting for lower-fat dairy. No food groups are omitted.
Eating this way promotes balance and moderation, while the flexible 20 per cent allows followers to enjoy food without feeling deprived or driven to bingeing. The flexibility also provides reassurance because it acknowledges that slip-ups can and will happen but are accounted for in the plan. It means fewer participants of the 80/20 diet drop out when compared with more restrictive diet plans.
How to calculate the 80/20 rule
One of the advantages of the 80/20 rule diet is that it’s not a rigid plan, this means you can adopt it in a way that works best for you. One option is to include treat meals throughout the week, so if you eat three meals a day, 17 during the week would be healthy and the other four may include treats. Alternatively, you may wish to look at the plan on a daily basis – with 80 per cent of your food for the day being healthy, but allowing 20 per cent for a biscuit with your cuppa, dessert after dinner or a few rashers of bacon for breakfast.
Whichever way you adopt the plan, you do need to keep in mind that the 80 per cent healthy time is needed to deliver results and portion control remains important, especially in the 20 per cent.

Who should follow the 80/20 rule diet?
Moderation is essential, making it a feasible approach for most people because it allows for a balanced diet with the occasional indulgence. The plan is less restrictive and easier to follow than many weight-loss diets so fits into most lifestyles.
If you dislike strict dieting, counting calories or carbs then this approach may be for you. Similarly, if you are not watching your weight but want a balanced approach to eating, then the 80/20 plan may be the answer.
Does the 80/20 rule diet work?
It’s important to emphasise this is not technically a weight-loss plan, but some weight loss may be experienced. Whether you lose weight on the 80/20 diet will depend on your starting point and how you adapt your original eating patterns.
The 80/20 rule diet is a useful long-term strategy for dieters who have already reached their weight-loss goal and need help with maintenance.
Is the 80/20 rule diet healthy? A nutritionist’s view…
The 80/20 rule diet offers a flexible, realistic and sustainable way of eating. Unlike a strict diet, it allows for life’s inevitable setbacks, as well as your social commitments and lifestyle. Because there is no list of specified foods, it can be adapted to fit within your own preferences.
Maintaining a healthy weight is a life-long process, there is no quick fix so it’s important to find something that works for you. The 80/20 rule diet may help you develop new healthy habits – the key to success is to establish the foundation (80 per cent) using whole foods, preferably unprocessed, such as wholegrains, vegetables, fruit, nuts, seeds and lean sources of protein such as beans, fish, meat and dairy. Remember to include plenty of hydrating fluids. Once you have established this base you can enjoy the flexibility that the plan offers.
If you are considering any form of diet, please consult your GP first to ensure you can do so without risk to health.
