Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

In this randomized, controlled, assessor blinded and prospective intervention study the investigators will evaluate the clinical feasibility and effectiveness of intermittent use of a fasting mimicking diet in patients with type 2 diabetes mellitus compared to usual care.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

100 individuals (men or women, ethnicity not specified) with type 2 diabetes and a BMI≥ 27, who are treated with diet only and have a HbA1c \> 48, or who are treated with diet and a dose of metformin can participate in the study. Participants will use a fasting-mimicking diet for 5 consecutive days per month. For the other days, there are no regulations. During follow-up of one year, several study parameters will be measured including HbA1c and antidiabetic medication dosage.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

Patients will be randomised to the intervention or control group.
Primary Study Purpose

TREATMENT

Blinding Strategy

NONE

Only measurements by assessors will be blinded.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Treatment group

Diabetes type 2 patients will take a fasting mimicking diet of 5 consecutive days a month, for a duration of 12 months. Besides this, they will receive usual diabetes care from the general practitioner.

Group Type EXPERIMENTAL

Fasting Mimicking diet

Intervention Type OTHER

The fasting mimicking diet is though to activate the metabolism as fasting would do, although the diet does include several meals a day and more calories than conventional fasting diets.

Control group

Diabetes type 2 Patients will have no intervention, they will receive usual diabetes care from the general practitioner.

Group Type NO_INTERVENTION

No interventions assigned to this group
