It’s A Battle Of The Diets: 5:2 Vs Low Kilojule

Is the 5:2 diet all it’s fessed up to be or would we be better off with a standard kilojoule-reduced diet? If you look at the simple weight loss equation – energy in vs energy out then they both seem pretty similar.

5:2 – 5 days 1,200 calories per day, 2 days 500 calories per day = 7000 per week

Standard: 7 days, 1,000 calories per day = 7000 per week

Researchers from Austin Health and the University of Melbourne found that the mean weight loss after six months for those on the standard kilojoule-reduced diet was 5.5kg, while those on the 5:2 diet lost on average 5.3kg, showing both diets do work in the short-term. ‘The 5:2 diet is an approach that’s becoming increasingly popular, but it hasn’t been well researched, with most studies to date being in animals,’ said Ms Conley.

A typical 500 calorie day would be:
Breakfast: 2 poached eggs and a handful of spinach.
Lunch: 60-80g of grilled chicken (less than the palm of you hand) with a side salad of cucumber and tomato
Dinner: Small piece of fish with veggies for dinner.

Although, those on the 5:2 diet reported being far hangrier than those with reduced kilojoule intake.

At the end of the day DAA President Liz Kellett said: ‘There is no such thing as a ‘one-size-fits-all’ approach. Anything that involves eating less and moving more is likely to get results, especially, as this study suggests, where you have ongoing support of a qualified health professional.’

So it looks like the jury is out on this one. If you want to keep your diet the same five days of the week and ‘fast’ for two days a week then go for it. Or you could opt for a healthy balanced diet 7 days of the week it depends on you. No matter which you choose the most important thing is that you stick to it for the best results.
