About

The investigators wishes to investigate the acute effect of a low carbohydrate meal on the plasma fatty acid (FA) composition compared with a control meal in a cross-over study of patients with type 2 diabetes (T2D).

In two trial days 12 participants with T2D will either have a low carbohydrate meal or control meal, measurements will be performed at baseline and continuously over 5 hours.

Full description

Type 2 diabetes (T2D) is the most common metabolic disorder worldwide, and with an increasing prevalence T2D has become a major healthcare burden.

Low carbohydrate diet (LCD) has become increasingly popular as a method of improving glycemic control in patients with type 2 diabetes. However, the higher content of especially saturated fat in LCD has raised concerns about harmful effects.

A previous study has shown increase in non esterified fatty acids after a low carbohydrate meal, but it still needs to be investigated how a low carbohydrate meal affects the plasma FA composition.

The aim of this project is to investigate the hypothesis that a single low carbohydrate meal results in an improved plasma FA composition in patients with T2D and that this, at least in part, corresponds to the changes observed after 6 months LCD.

The study will be conducted as a cross-over trial with 12 participants with T2D. The participants will randomly be assigned to either start with the low carbohydrate meal or a control meal with a 2 weeks washout period.
