Programme pathway

The programme takes place over 12 months and is split into 3 stages. After 12 months, participants can continue to self-track their activities in the Oviva app and will have lifetime access to Learn resources. 


Participants will first have a consultation with a Diabetes Specialist Dietitian who will help them prepare for the journey ahead. Together they’ll agree on goals for the programme, and come up with an action plan to help them achieve them over the 12 months.


12 weeks on a Low Calorie Diet using Total Diet Replacements products where they will replace all meals and snacks with shakes and/or soups. These contain all the essential vitamins and minerals needed. During this time, they will receive frequent support from their health coach. In the following 4 weeks, they will undergo Food Reintroduction with support.


For the remaining eight months they will work on sustaining these healthy habits and will continue to have access to the Oviva app and learning resources. Find more about our digital tools here.
