One Week Diet System Review - A one week wonder?

Is it really possible to lose a significantly noticeable amount of weight in just one week? We find out below.

What is the One Week Diet System?

The One Week Diet System is a natural digestive cleanse, which doubles up as a meal replacement for your regular breakfast. It is called the ‘One Week’ diet system as it claims you can expect to see measurable weight loss results after just one week of using it.

Sounds great, but at a cost of £29.99 per week it seems a little steep compared to other diet products, so surely it has some hard evidence to back up its super fast weight loss claims?

One Week Diet System ingredients

It states on the website that the One Week diet system is a liquid detox cleanse, which is completely safe with natural ingredients and packed full of vitamins and minerals. A full list of ingredients can be found on the Health To Happiness website.

How to use the One Week Diet System

The One Week Diet System is designed to be taken twice daily as a meal replacement, and used alongside their exercise program and sensible eating plan, which includes suggested low calorie meal recipes. When you first start the program, you can use the system for two weeks in a row, but then you should take it every other week until you reach your desired results. Quite worryingly this is to give your body a “rest”.

Are there any side effects when using the One Week Diet System?

There is no mention of whether there are any side effects or not, on the One Week diet system website.

Is the One Week Diet System clinically proven?

No. The One week diet system is not clinically proven to help you lose weight. It says it should be used in conjunction with doing a moderate amount of exercise and eating a sensible diet, but then only says you could lose weight – there are no guarantees.

The One Week diet system conclusion

We were disappointed with the One Week diet system, it seems to offer something that is too good to be true – significant weight loss in just one week, but it just cannot back this up with results. As you delve further in to how the One Week diet system actually works, you realise it’s not much more than a liquid drink which maybe wouldn’t work without the exercise it tells you to do, and the lower calorie meals it tells you to eat.

The other thing which lets it down is the price, at a costly £29.99 for one bottle which lasts a week, or £59.98 per month if you continue to use it, it’s hardly cheap. Also when you are paying this much for a product, you want the satisfaction of knowing that it’s been through clinical tests proving it can increase weight loss, so you know you’re money is well spent. Unfortunately the One Week diet system cannot provide this kind of evidence.

One Week Diet System Verdict: one-week-diet-system-reviews-img14

3 / 5

The lack of proof and clinical testing, plus the high cost lets it down.
If you're looking for a suitable alternative which is fully guaranteed to work, then we highly recommend Proactol.
