LEIPZIG, GERMANY — For patients newly diagnosed with type 2 diabetes, nutrition therapy is highly effective at achieving remission. “The greater the reduction in body weight, the higher the chances that blood sugar levels will normalize,” Diana Rubin, MD, said at the fall press conference of the German Diabetes Society (DDG). Dr. Rubin is conference president and chief physician of the Center for Nutritional Medicine and Diabetology at Vivantes Humboldt Hospital and the Spandau Hospital, Berlin, Germany.
Because of the development of modern medicines, nutrition therapy has increasingly been pushed into the background over the past 50 years. However, nutrition therapy and weight reduction can effectively delay diabetes for years, said Dr. Rubin. The patients are healthy, without being healed.
Nevertheless, the remission is rarely permanent. Most of the patients develop type 2 diabetes again after 5 years.
Personalized Nutrition Therapy
It is not just developments in medicine that have pushed nutrition therapy into the background. Another contributing factor is that statutory health insurance companies do not cover personalized nutrition counseling as standard, said Dr. Rubin.
Modern research in nutrition therapy has shown that patients with diabetes should receive personalized treatment. However, this idea is not taken into consideration in current diabetes training programs, which are the only forms of nutrition therapy covered by statutory health insurance companies.
Instead, nutrition information is mostly conveyed through group training sessions. Individuals do not necessarily find each other again. What’s more, these sessions are seldom led by nutrition experts. “It is rarely helpful to use a ‘one size fits all’ approach, as is often the case with these group training sessions,” said Dr. Rubin.
The DiRECT study, in which patients reduced their weight by 15 kg and achieved remission rates of almost 90%, is an example of how nutrition therapy can be highly effective. This is especially true if the aims and methods are determined on an individual basis and if there is frequent contact with a therapist. German and international guidelines, including the DDG’s best practice guides from 2022, highlight the importance of personalized nutrition therapy.
Telemedicine Encourages Adherence
“It is very important to consider the current living situation of the person concerned,” said Dr. Rubin. “It is important to set small objectives that can also be implemented in everyday life.” This can only succeed with a professional face-to-face consultation. “Achieving this objective then also becomes realistic — i.e., losing 10% to 15% body weight and maintaining this loss,” she said. “Long-term monitoring is needed to maintain this weight.”
Weight reduction methods should generally be determined according to the preferences of the person concerned, since dietary habits and environments are personal. For example, reducing the intake of carbohydrates and fats, intermittent fasting, or using meal replacement drinks can all be considered.
New data also show that digital apps available on prescription (DiGA) can be helpful for support; this idea is reflected in the DDG’s nutrition best practice guides for patients with type 2 diabetes.
“Studies show that adherence is highly dependent on the amount of contact with therapists and the long-term nature of the treatment,” said Dr. Rubin. She referred to the need for long-term monitoring, during which the patient can be repeatedly reminded of the therapeutic objective. “In this respect, I see a lot of potential in digital apps, and also in telemedicine, to cater to the short-term contact with the person concerned.”
A 2015 meta-analysis of 92 studies revealed a significant reduction in A1c for patients with type 1 or type 2 diabetes when using telemedicine nutrition therapy. Dr. Rubin frequently prescribes DiGAs, which are approved for obesity, “simply because I can recognize it makes it easier for many patients to stick to their goals.”
Dr. Rubin also recommends connecting with sport groups and self-help groups. “Maintaining the weight is a long-term project.”
