About this trial
Overweight patients with type 2 diabetes are offered a total diet replacement with the goal of weight loss and diabetes remission. Study participants are randomised to eHealth follow-up or face-to-face follow-up, but the dietary advice is the same in both groups. A healthy control group with normal glucose tolerance is examined once but is not randomised and does not receive any intervention.

Treatment groups
Trial outcomes
Primary outcomes
HbA1c
HbA1c without diabetes medication as a continuous outcome (HbA1c correction according to Tsapas et al 2020 if on diabetes medication). The outcome will be tested for non-inferiority first, with a non-inferiority margin of 8 mmol/mol; followed by a test for superiority.
Secondary outcomes
HbA1c
HbA1c without diabetes medication as a continuous outcome (HbA1c correction according to Tsapas et al 2020 if on diabetes medication). The outcome will be tested for non-inferiority first, with a non-inferiority margin of 8 mmol/mol; followed by a test for superiority.
Diabetes remission
Number of participants with HbA1c \< 48 mmol/mol without diabetes medication. The outcome will be tested for non-inferiority first with a non-inferiority margin of 10 percentage points; followed by a test for superiority.
