I decided to try intermittent fasting and just gave up eating anything except dinners. I was quite hungry the first two days. I was a little grumpy, too. Then the third day my body got used to it and no signs of hunger so I did it for 6 days in a row. I felt fantastic and lost quite a bit of weight.

During the day, I feel so much more focused… You have this very focused point of mind. The time back from breakfast and lunch allowed me to focus more on what my day is. Also, I can go to bed and actually knock out in 10 minutes, if not sooner than that.

I feel the senses and cell activity get much more effective. Your body is using all the food. If I eat one meal after 6 pm, I can eat what I want. The next day, I'm slim again. That’s making the body work. But as we eat all day long, the body is not shutting down. It’s not effective anymore. It doesn’t go into survival mode. It’s not natural again. So it’s beginning to store up all the fats because it doesn’t know what to do. Because the deeper mechanisms are not working anymore.

During the second week of the challenge you will learn how to prepare balanced meals and learn more about healthy nutrition. 

Given you only eat one meal a day, it’s extremely important your meal is well balanced and includes all the required nutrients you need for the rest of the day.

Are you ready? Join today, start on Monday.

The last week of the challenge is focused on making sure the habit of eating one meal a day you have developed stays with you after the challenge is over (if you wish to).

Let’s be honest, free things do not motivate us. Cognitive psychologists found out why and they call it loss aversion. In simple terms, we are more motivated by fear of losing rather than a satisfaction of gaining.

It might sound counter-intuitive, but by paying for the OMAD challenge, you have a higher chance of successfully completing it and therefore enjoying all the OMAD benefits.
