Patients with type 2 diabetes who followed a low-carbohydrate diet for six months may get better, leaving less medication or no need for at least some time. Other diets, such as a low-fat diet, do not seem to do this.
In their study, the researchers came to the conclusion that doctors could consider low-carbohydrate diets for the treatment of type 2 diabetes: data from eight studies with 264 participants showed that in almost a third of people, with a maximum of 26 percent of the daily calories consumed came from carbohydrates, after half a year the diabetes had decreased. They also lost more weight, needed less medication, and had better fat metabolism than diabetics who followed other diets. This is what researchers report in the specialist journal “BMJ”.
For most people, however, the benefit only lasted for a year, and then quality of life and cholesterol levels deteriorated again. Nonetheless, the researchers conclude that doctors should encourage their patients with type 2 diabetes to eat a low-carb diet. The need for diabetes medication must be monitored and adjusted if necessary.
In the opinion of the authors, further well-designed, calorie-controlled long-term studies are necessary in order to better shed light on the effects of low-carbohydrate diets: They can better capture the effects on body weight, the decline in diabetes and on cardiovascular health than through an overarching evaluation of the data from various studies, as was carried out in this work.
