The second week of the challenge will involve some changes to your diet and fasting timing. Once you feel comfortable with fasting daily, you will get to test your limits and extend the fasting period for a few hours.

Toward the end of the week, you will be introduced to the basics of healthy eating to compliment your new healthier lifestyle.

Are you ready? Join today, start on Monday.

The last week of the challenge is focused on making sure the habit you have developed stays with you for life. You will learn about different types of Intermittent Fasting and tools you can use to stay on track with Intermittent Fasting after the challenge is over.

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 this challenge, you have a higher chance of successfully completing it and therefore enjoying all the benefits associated with the Intermittent Fasting.

Also – it supports us and our team to keep providing you a ton of useful content that we share every week for free.

Joining Facebook group is optional – it’s a great chance to interact with others and make connections, yet you can perfectly fine do the challenge without joining the group. 

You will receive daily content and emails from us to keep you motivated, and can always reach out to our team through email if needed.

If you haven’t received your email from 21 Day Hero, please check your spam/junk and promotions folder – it might have accidentally landed there. You can also make a search in your inbox for an email from hello@21dayhero.com.

Yes, all our products are a one-time payment and not a subscription.

If you want to continue your diet after the 21-day period, you will have to purchase a new meal plan. Or continue with a new challenge. No additional charges will ever occur.
