The longest trial intervention studies did not show a difference in weight change .
This review shows that there are no consistent differences in weight and A1C changes over the long-term treatment with LCD and LFD , UCD or LGID
INTRODUCTION Low carbohydrate diets ( LCD ) have shown beneficial effects on short-term weight reduction programs for obese individuals without diabetes , but the long-term evidence of efficacy on individuals with type 2 diabetes is not conclusive .
OBJECTIVE To evaluate , the effectiveness of 12 or more weeks of LCD compared to Low Fat Diet ( LFD ) , Usual Care Diet ( UCD ) or Low Glycemic Index Diet ( LGID ) on weight reduction and AIC on type 2 diabetes individuals .
Lasting improvement of hyperglycaemia and bodyweight: low-carbohydrate diet in type 2 diabetes. A brief report.
In two groups of obese patients with type 2 diabetes the effects of 2 different diet compositions were tested with regard to glycaemic control and bodyweight . A group of 16 obese patients with type 2 diabetes was advised on a low-carbohydrate diet , 1800 kcal for men and 1600 kcal for women , distributed as 20 % carbohydrates , 30 % protein and 50 % fat .  Fifteen obese diabetes patients on a high-carbohydrate diet were control group .  Their diet , 1600 - 1800 kcal for men and 1400 - 1600 kcal for women , consisted of approximately 60 % carbohydrates , 15 % protein and 25 % fat . Positive effects on the glucose levels were seen very soon . After 6 months a marked reduction in bodyweight of patients in the low-carbohydrate diet group was observed , and this remained one year later . After 6 months the mean changes in the low-carbohydrate group and the control group respectively were ( + /-SD ) : fasting blood glucose ( f-BG ) : -3.4 + /- 2.9 and -0.6 + /- 2.9 mmol/l ; HBA1c : -1.4 + /- 1.1 % and -0.6 + /- 1.4 % ; Body Weight : -11.4 + /- 4 kg and -1.8 + /- 3.8 kg ; BMI : -4.1 + /- 1.3 kg/m _ and -0.7 + /- 1.3 kg/m_. Large changes in blood glucose levels were seen immediately . A low-carbohydrate diet is an effective tool in the treatment of obese patients with type 2 diabetes
