Type 2 DiabetesDiNA-DNCT02459496
Diabetes Nutrition Algorithms in Patients With Overt Diabetes Mellitus
A study testing dietary consulting and advise in people with Type 2 Diabetes and NAFLD, run by German Institute of Human Nutrition at 2 sites in Germany.
Trial summary
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.

About this study
Official title: 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.

An intensive intervention of 3 weeks is followed by an 11-month maintenance phase to consolidate metabolic improvements.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
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.

Where is the study taking place?
The record lists 2 sites in Germany. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Stefan Kabisch, Dr. med. (030 450 514 ext. 429, stefan.kabisch@dife.de), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
change in insulin secretion (glucagon stimulation test) (time frame: 3 weeks, 1 year). The study lists 5 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 24 Jun 2020; AzTrials last refreshed its copy on 7 Nov 2026.
