Danish Study Shows Lower Carbs, Higher Fat, and Protein Can Help Improve Type 2 Diabetes

Danish Study Shows Lower Carbs, Higher Fat, and Protein Can Help Improve Type 2 Diabetes

According to a recent Danish study conducted at Bisperbjerg Hospital in collaboration with other partners, such as University of Copenhagen, patients with type 2 diabetes potentially can improve their ability to regulate blood sugar levels if they eat food with a reduced carbohydrate content and an increased share of protein and fat.

The obesity crisis is ravaging countries, such as America. Denmark is known as a land of lean, athletic cyclers. However, the Danish Health Authority reports that up to 85% of newly diagnosed type 2 diabetes patients are overweight. Like many diets worldwide—patients are advised to focus on weight loss by consuming less fats and more carbohydrats with a low glycemic index.

The Study

The Danish research team enrolled 28 type 2 diabetes patients over a 12 week period. The patients were given a conventional diabetes diet (high carbohydrate content) for six weeks and for the next six weeks, they were offered a diet with less carbohydrate content, high protein content and moderately increased fat content. Diet types were allocated in randomized order.


The purpose of the study concerned the investigation of the effects of the diet without interference from weight loss. Hence, the patients were asked to maintain their weight.

The study confirms the assumption that a diet with a reduced carbohydrate content can improve the patient’s ability to regulate their blood sugar all the while avoiding the situation where patients lose weight.

The findings remove weight loss from the equation as the investigators suggest “Previous studies have provided contradictory conclusions, and weight loss has complicated interpretations in a number of these studies.”


The researchers noted “The study shows that by reducing the share of carbohydrates in the diet and increasing the share of protein and fat, you can both treat high blood pressure and reduce liver fat content” states Thure Krarup, MD, Department of Endocrinology, Bispebjerg Hospital.
