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!

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.
