Replacing breakfast with the One Week meal combined with their exercise and meal system the manufacturers claim you will see results in one week – hence the catchy name!

So what is One Week Diet?

Reviewing the One Week system in more detail raises a number of questions.

Firstly, very little information about One Week is available on their website. Looking for ingredients – who knows! The ingredients are apparently natural and completely safe, loaded with vitamins and minerals. The only stated ingredient is Aloe Vera.

Clinical evidence also appears to be lacking to backup their claims. Their website simply show consumer testimonials of “impressive figures“.

One Week Diet side effects

The manufacturers report no side effects when using their liquid meal replacement. They do suggest not using their product continuous though.

Recommend One Week Diet?

We would not recommend using One Week Diet as a serious slimming aid. The lack of information about One Week available raises too many concerns about proven clinical evidence to support their claims.

Taking the One Week Diet system is unlikely to cause any side-effects, apart from maybe wasting your money. The One Week Diet system is not cheap!
