Accelerate Your Keto Results in only 4 Days

The Keto Results Challenge 3.0 Starts In:


Take Control of fat loss with the ketogenic diet, fasting and exogenous ketones...
AND make it an Easy lifestyle... So that Your Fat Loss Stays! 

an all out event where you can make a big Leap forward, have fun, Make Friends, win Prizes and help raise awareness in Europe about the value of ketogenic diets & fasting

Because You Don't Want to Wait Any Longer for Results...

Here's What This is All About: Results Acceleration & Pushing Europe Forward

#1 Challenges Get You More Results than Courses

Get inspired. get supported. have fun. and hit your weight loss goals.

The Keto Results Challenge is about you and your friends taking action.

It's not a course. Because courses don't work. You can learn everything. But if you've been working on your health or weight loss a while, you already know that knowing something - doesn't make it happen.

What makes it happen is it being easy so it becomes a natural lifestyle for you. And the reality is that most of what makes it easy is the environment you're in.

When you are surrounded by friends working on the same weight loss goals. When you have clear easy steps to follow. And where you see people like you succeeding... it becomes effortless.

#2 europe lags far behind the uSA in keto & fasting... 

Few know what it is. Few search for it. Few benefit from it.

Interest and use of the ketogenic diet and fasting has always lagged behind the USA.

The problem with this is it makes living the lifestyle harder for everyone in Europe. We have less access to knowledge. There are fewer health professionals educated in these tools. There are fewer food and nutrition products to help make the lifestyle more convenient.

And ultimately... we believe there's more suffering, because ketogenic diets and fasting can make a real difference to people's weight loss success and health.

About the WHtR (Waist-to-Height Ratio)

The WHtR (Waist-to-Height Ratio) is the best science-based metric to track the progress of fat loss results.

Research studies show clear cut-offs for reducing mortality and long term health risks at the 50% cut-off level.

It also removes the biases that other measures like weight and BMI (Body Mass Index) suffer from. So it is a better and more accurate measure of fat loss progress.

The WHtR is calculated by dividing your waist by your height.

I have been following the program for more than seven weeks, results are fantastic so far. Erin was amazing, her support and advice has helped put me on the road to feel better! I would highly recommend this program.

Reem hazim

I love love love the Ketosource team and everything they stand for! They are always at hand with research backed science that is practical to apply in day to day life and the coaching is second to none.

I finally feel like I have the perfect balance between having a coach to keep me accountable and guide me through my heath journey, whilst being encouraged to find a path that’s going to work for me as an individual.

Thank you for everything you do guys! 

angie white

I love being a member of the Ketosource community. It’s a knowledge, caring and resourceful place to be.

I have received coaching from Erin since 2018 and now benefit from the online support community. Erin is always warm, funny and super supportive, as are the other members of the group. 

Having struggled with obesity all my life, I thought that at aged 62 I would never be a healthy weight. I have been amazed by the Keto lifestyle. I dropped 38lbs with very little exercise and never feeling hungry.

I really recommend Ketosource.


The advice given to me was easy to follow and the coaches at Ketosource are really knowledgeable, friendly and helpful.
