The One Week Health Diet by One Week Health offers rapid weight loss in as little as one week by drinking liquid meals. Very little information is available on the One Week Health Diet website (oneweek.co.uk). Unfortunately the actual ingredients in the liquid meals (plant juice) are not disclosed. This is a cause for concern.

The One Week Health Diet is a diet plan that has two components:

1. Liquid meals taken as a replacement of breakfast and an afternoon snack.

2. The One Week Health Diet Plan must be followed in combination with the liquid meals.

How does the One Week Health Diet work?

The One Week Health Diet liquid meals are claimed to act as a body detoxifying system. Formulated from plant extracts, the concentrated plant juice is said to be filled with vitamins, amino acids and electrolytes. The weight loss achieved through body cleansing diets usually lasts for a few days. In the first two weeks, users lose water weight and not fat.

It appears that One Week Health Diet has to be used for 1-3 months to lose significant weight. After first 2 weeks of usage, the product has to be taken on alternating weeks. On average (based on customer testimonials and user feedback online) a weight loss of 5-8 pounds in a month is realistic with the One Week Health Diet.

How much does One Week Health Diet cost?

The One Week Health Diet costs £30 a week. In the first month three weeks supply of the product is needed, amounting to £90.

One Week Health Diet side effects

The ingredients in the liquid meals or plant juice are not disclosed. As a consequence, it is not possible to predict potential side effects. The user feedback online is not particularly positive. Many dieters claim that they just lost water weight using the One Week Health Diet. As the product is a body cleansing system, it could potentially cause stomach upsets and diarrhea.

One Week Health Diet conclusion

It is possible to lose 5-8 pounds in a month just by eating healthy and doing some extra exercises such as cycling or brisk walking. The price of  the One Week Health Diet appears very high for the weight loss that can be achieved.

Without clinical trials to endorse the weight loss claims, or even details of what the ingredients are, the One Week Diet System must be used with caution.
