Instead, you will get a personalised science-based program tailored to your needs and requirements.

This depends on your individual needs. The initial consultation will investigate your goals so that you can reach your desired results. Then a tailored plan is put in place. 

Follow up sessions are crucial to success! These provide nutrition education at your leisure, tweak plans, review progress and work through barriers. Follow up sessions are recommended after 4 weeks which you can easily book through the Odhealth app. Here at Odhealth, we focus on long term sustainable goals.
