”Bernes yttrande:

Akademiska sjukhuset Uppsala(The Academic Hospital)                                        2007-12-13

Torsten Mossberg medicinalråd (medical adviser) Enheten för behörighet och patientsäkerhet (Department for licensing and patient safety) SOCIALSTYRELSEN (The Swedish Board of Health and Welfare) 106 30 Stockholm

Regarding licensed physician Annika Dahlqvist’s advice concerning ”Carbohydrate Tight” diet. In regard to weight reduction and ”wellbeing” documented in a background material covering Low-Carbohydrate diet.

Question: Is this treatment in accordance with science and well-tried experience?

The answer to this question is yes, reserving the fact that the scientific basis in the form of randomized controlled trials is much narrower than it is regarding diets with a higher content of carbohydrates and that long time trials (> 1 year) is lacking.

Furthermore, considering the aforementioned reasoning, it’s especially important that some of the practitioner’s self-evident principles of the profession are met. Any kind of intervention, whether it be related to drugs or lifestyle changes such as dietary advice, should be followed by a thorough, regular follow-up and record keeping of the patient’s healthiness and physical data(such as weight and waist measurement), how the patient has apprehended the advices given and the level of appliance thereof. Regarding patients with type 2 diabetes and/or overweight often combined with dyslipidemia or high blood pressure, surveilling HbA1c, blood lipids, blood pressure, P-creatinine and microalbuminuria is crucial. Since the longtime effects of this method are unknown there may be strong reason to recommend following-up over time using a national quality registry such as the National Diabetes Registry, that documents all of the above variables and can be used in local quality follow-up.

This advisory opinion is not the place for detailing the extensive literature research that I’ve used as a basis for my conclusions. Some relevant reviews are listed below. Substantially, they’re briefing randomized controlled trials aimed at weight reduction for the obese and a sprinkling of trials using subjects with type 2 diabetes. One of the systematic reviews (2003) concluded that the evidence to support recommending a low-carbohydrate diet was insufficient but there was no evidence for it being harmful in the short run at least. It has been difficult to prove that the carbohydrate share alone has had an effect on the weight reduction since several trials has ascribed to a coincidental total energy reduction as an essential cause for the weight loss. One reservation has been that upon consuming a larger share of saturated fat in the diet one is liable to get a minor increase of LDL cholesterol, something that has been observed in longer trials, and emphasizes the responsibility to follow-up patients with relevant sample-taking over time.

Observing the swedish diet debate can lead to the comprehension that the scientific basis is found in the evening papers, debate articles by laymen and in popular books on so-called fashion-diets. A research into scientific medical literature (see references) however indicates that a number of randomized controlled trials and reviews of low-carbohydrate diets are found in leading journals with a high impact such as New England Journal of Medicine, Diabetes, Annals of Internal Medicine, JAMA and American Journal of Clinical Nutrition. Even if the literature so far is much more scarce than the one documenting the effects of todays commonly recommended diet it shows that there is a serious scientific evaluation and debate going on about the possible positioning of carbohydrate restriction in the treatment of overweight and type 2 diabetes.

To sum up, with reservation for a narrow scientific basis, a lack of long time trials and trials that evaluates the effects on patient related effect measurements (cardiovascular diseases and for diabetes microvascular diabetic complications), a carbohydrate tight diet can today be said to be in accordance with science and well-tried experience for reducing an overweight and type 2 diabetes the motivation being that a number of trials has shown effects in a shorter run and that no evidence for it being harmful has emerged in systematic literature researches performed so far. There’s no scientific support yet for treatments in excess of 1 year. A thorough evaluation of long time treatment results is therefore an important demand on the practitioner.
