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 .
Short-term effects of severe dietary carbohydrate-restriction advice in Type 2 diabetes--a randomized controlled trial.
OBJECTIVE This study sought to examine the effects of a 3-month programme of dietary advice to restrict carbohydrate intake compared with reduced-portion , low-fat advice in obese subjects with poorly controlled Type 2 diabetes . RESEARCH DESIGN AND METHODS One hundred and two patients with Type 2 diabetes were recruited across three centres and r and omly allocated to receive group education and individual dietary advice .  Weight , glycaemic control , lipids and blood pressure were assessed at baseline and 3 months . Dietary quality was assessed at the end of study . RESULTS Weight loss was greater in the low-carbohydrate ( LC ) group ( -3.55 + /- 0.63 , mean + /- sem ) vs. -0.92 + /- 0.40 kg , P = 0.001 ) and cholesterol : high-density lipoprotein ( HDL ) ratio improved ( -0.48 + /- 0.11 vs. -0.10 + /- 0.10 , P = 0.01 ) . However , relative saturated fat intake was greater ( 13.9 + /- 0.71 vs. 11.0 + /- 0.47 % of dietary intake , P < 0.001 ) , although absolute intakes were moderate . CONCLUSIONS Carbohydrate restriction was an effective method of achieving short-term weight loss compared with st and ard advice , but this was at the expense of an increase in relative saturated fat intake
