The 4 × 4 diet is a new weight loss method for losing body fat developed by personal trainer Erin Oprea, a former marine and now coach of the likes of Carrie Underwood.
Women who want to look slim but have little time to devote to diets and the gym.

From the experience with super-busy customers, Erin has developed the 4 × 4 Diet , which as she explains in her book, which will also be released in Italy, comes from an intuition that she had already as a girl.

And that is that the cardinal principles for having a fit body are few, basically 4 for nutrition, plus the idea of ​​constantly moving, which Erin has condensed into just 4 minutes of Tabata training a day.

To be clear, the Tabata workout is a short and high intensity workout useful to speed up the metabolism.
It’s a stressful workout, even if it only takes a few minutes.
However, it raises the metabolism allowing us to burn more calories when we are not exercising, therefore for the rest of the day.
And then we hurry up in no time, so we can also do it every day.

For this reason, the 4 × 4 diet is ideal for those who want to lose body fat.

On the one hand, we act on nutrition , re-establishing 4 good dietary routine habits, on the other hand we engage in 4 minutes of intense training, which in the book are divided into three different protocols. One for beginners, one for moderately trained people and one for sportsmen.

Erin Oprea explains that practically speaking, to lose body fat and have an enviable physique, nothing else is needed.
Let’s see her 4 × 4 Diet in detail.
