Lacking in savoury flavours

The concept is good but the flavours are really hit and miss. The chocolate and Vanilla drinks are very good if mixed with Cold water (refrigerator cold) it's like having a nesquik drink. The Coffee is ok and the cereal bars do the trick. HoweverThe soups are terrible I have had 5 soups mixed with warm water and the thought of them makes.me feel nauseous. Their is a lack of savoury flavours like Chicken or Tomato in this set which makes the 6 week plan mentally Challenging as I find myself looking for a savoury option.

Gives you energy but balance between products is not the best

I was surprised to realise that I had all the energy I needed to get on with my day + do easy exercise. The first 4 days I had headaches but, as described in the manual - they disappeared in the 5th day. Apparently it's a side effect of Ketosis. I was not hungry. These products fill you, especially the desserts (mine was vanilla cream). My problem was that most of the products were sweet. I would have preferred to have a savoury meal once a day. In the deal pack there were few soups (which is the only savoury option) so in the second week almost all the meals were sweet. A big plus is that you don't cook so you don't have to clean as much. No dirty plates, pots and pans. apart from the shakes/soups/bars/desserts you need to eat 2 cups of vegetables a day. That was really nice to actually chew on something! My husband and I did this together and he absolutely hates vegetables, but he liked parsnip and carrot chips, also baked cauliflower (no cheese, just some oil spray and let it get crunchy). We did it for two weeks and are going to do another two weeks in a few days. At least for us it was good and we lost a lot of weight, but we couldn't face more than two weeks in a row so we took two weeks off and followed a normal diet. Generally speaking it's a very good diet if you want to lose weight fast. I would recommend it.
