About the thesis
Nutritional therapy is recognized as a first-line therapeutic intervention in patients with type 2 diabetes. However, dietary recommendations are ambiguous and no clear consensus exists regarding the macronutrient distribution of the diabetes diet.

Current Danish diabetes dietary guidelines recommend a macronutrient distribution of 45-60 energy percent (E%) from carbohydrates, 10-20 E% from protein and <35 E% from fat. The American diabetes association has recently recommended carbohydrate-restriction as one out of several viable nutritional therapeutic interventions.

Although meta-analyses have revealed receding or absent long-term effects, it has been suggested that carbohydrate-restriction may improve glycemic control. Nevertheless, evaluation of dietary interventions remains complex as most feeding studies are influenced by a concomitant weight loss affecting the metabolic outcomes.

This PhD project aimed to investigate the effects of a conventional diabetes diet (carbohydrates/proteins/fat; 50/17/33 E%) and an iso-energetic carbohydrate-reduced high-protein diet (carbohydrates/proteins/fat; 30/30/40 E%) during 6 weeks of full meal provision aiming at weight stability in patients with type 2 diabetes.
