Diabetes Nutrition Algorithms in Patients With Overt Diabetes Mellitus (DiNA-D)
Dietary Strategies to Improve Metabolism and Body Weight in Type 2 Diabetes
Basic treatment of type 2 diabetes should focus on diet, physical activity and lifestyle. Nevertheless, in early and late stage of T2DM, lifestyle intervention is mostly substituted by pharmacological intervention, although lifestyle modification and dietary treatment would be favourable.
The researchers therefore investigate dietary strategies such as low-carb and very-low calory diets regarding their potential to improve metabolism and body weight in (mostly) long-term T2DM patients.

Basic treatment of type 2 diabetes should focus on diet, physical activity and lifestyle. Nevertheless, in early and late stage of T2DM, lifestyle intervention is mostly substituted by pharmacological intervention, although lifestyle modification and dietary treatment would be favourable.
The researchers therefore investigate dietary strategies such as low-carb diets and very-low calory diets regarding their potential to improve metabolism and body weight in (mostly) long-term T2DM patients.
An intensive intervention of 3 weeks is followed by an 11-month maintenance phase to consolidate metabolic improvements.

Intervention / Behandling |
|---|---|
|
Aktiv komparator: low-carb diet, followed by conventional DGE diet
subjects receive dietary consulting for a first phase of 3 weeks, being represented by a very-low calory low-carb ketogenic diet (VLCKD, below 40 g carbs per day), followed by an isocaloric or moderate hypocaloric low-carb diet (below 40 kcal% carbs per day)
|
first phase: 3 weeks of very-low calory diet (low-carb or normo-carb) second phase: 49 weeks of eucaloric diet under DGE guidelines
|
|
Aktiv komparator: very-low calory diet, followed by conventional diet
subjects receive dietary consulting for a first phase of 3 weeks, being represented by a very-low calory diet (VLCD; MODIFAST substitute, approx.
1200 kcal/day), followed by a conventional isocaloric or moderate hypocaloric diet under DGE guidelines
|
first phase: 3 weeks of very-low calory diet (low-carb or normo-carb) second phase: 49 weeks of eucaloric diet under DGE guidelines
