Twelve weeks

The diet lasts for 12 weeks and consists of 3 different phases. Each phase lasts 4 weeks. 

During the first phase you consume few calories. In this phase you have to learn to deal with the feeling of hunger. 

The second phase revolves around 'carb cycling': one day you eat a lot of carbohydrates, the other a little. In this phase you can eat more than in the first phase. 

In the third and final phase you eat little for 6 days a week. On the 7th day you can 'refeed'. By refeeding is meant that you can eat more calories than you need (500 calories extra).

Sports

According to the book, you are suitable for the sports programme if you have a fat percentage under 24% (as a woman) and if you already exercise at least 4 days per week. If you follow this programme it is important that you take in the right nutrients. According to the authors, training without the necessary proteins does not lead to an increase in muscle mass (rather a decrease). Therefore, this programme includes a lot of chicken and dairy products.

Strength training

The sports programme includes a lot of power training to build up muscle mass. The training consists of different exercises that you can do at home. Besides strength training, it is also important that you do cardio. At least one hour of cardio training each time should help you to burn fat.

Food

This diet puts you in an imbalance rather than helping you learn to eat healthily. Not only is it strict, it is unnecessarily strict. Complicated terms are used, making it sound like new and sound principles. That a diet can consist of phases is common, but the time frame for the diet (12 weeks, 12 kilos) is literally too good to be true. Besides, it is a dubious issue what to do if you have completely pulled yourself out of balance. A relapse into your old habits is a danger in this regard. In short: this diet is not healthy for healthy people, and definitely not recommended for people with health risks such as diabetes, cardiovascular diseases and gastrointestinal complaints.

As far as I am concerned, this is a very effective 'diet'. Because you exercise a lot in combination with eating considerably less and lighter, it has an immediate effect. This also makes it a bit heavy, you have to love sports I think. I must say that I see it as a guideline for my food and sport combo, I hope to be able to maintain this pattern for longer. If you do it in 12 weeks, it seems very tough to me.
