This low-calorie diet service for people with Type 2 diabetes launched across NCL in November 2020, as part of a two-year pilot. NCL is one of 10 sites across England that will be rolling out the new, innovative and free service. Five hundred patient places will be available.

The NCL service, offered by Xyla Health and Wellbeing, provides a digitally led one-year programme to support healthier lifestyle, weight loss, and remission of Type 2 diabetes. The programme is based on two large studies, which showed that, because of low-calorie diet treatment, people living with Type 2 diabetes who were overweight could improve their diabetes control, reduce diabetes-related medication and even achieve remission.

Programme overview

The one-year programme consists of 12 weeks of low-calorie total diet replacement (shakes and soups, products provided by Xyla Health and Wellbeing) followed by reintroducing food, focusing on movement and maintaining a new healthy eating lifestyle. The unique programme: 

  • combines specialist nutrition, psychology and physical activity
  • supports rapid weight loss and long-term behaviour change
  • delivered entirely remotely via the Xyla Health and Wellbeing app, with supporting resources and 1-2-1 telephone coaching
  • delivered by Xyla Health and Wellbeing, GPs, practice nurses, diabetes practitioners, dietitians, clinical psychologists and exercise specialists  

Referrals

Referrals to the service are made from primary care. To reduce workload on practices, the NCL low-calorie diet steering group advises that practices may wish to operate at a PCN level to identify eligible patients and make referrals; for example, the PCN practice-based-pharmacist could lead on engaging with the service.

Low-calorie diet eligibility searches are now available on practice clinical systems to support identification of appropriate patients. It is important that all patients who are referred must be engaged and committed to taking part in the 12-month programme. Some practices may have already been contacted by interested patients. It is recommended to get back in touch with engaged patients to discuss eligibility for the service. 


Please see the Downloads section for the Medication Changes Guidelines, practice patient allocation profile and several other useful resources including FAQs.

    • if not on diabetes medication, HbA1c 48 mmol/mol or higher
    • in all cases, HbA1c must be 87 mmol/mol or lower
    • if there is any concern that HbA1c may have changed since last measured, such that repeat testing may indicate that the individual would not be eligible for the programme at present, HbA1c should be rechecked before referral is considered
