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 .
Euglycemia and normolipidemia after anti-obesity gastric bypass.
UNLABELLED Weight loss and resolution of comorbidities is well established after modern bariatric procedures , however chronology of glyco-lipidic biochemical response is still debated . OBJECTIVE Aim ing to analyze this variable as well as its correlation with food amount and composition , a prospect i ve study was design ed . METHODOLOGY Eighty consecutive patients undergoing Roux-en-Y gastric bypass were investigated every three months until one year after surgery . Females only were accepted and variables included general and nutritional course as well as glucose and lipid measurements . Energy intake was documented including percentage of macronutrients in the diet . RESULTS Surgery was successful with about 71 % excess body weight loss at the end of the first year . Mean energy intake on the 4 postoperative quarters was respectively 519.6 + /- 306.6 , 836.0 + /- 407.9 , 702.1 + /- 313.1 and 868.8 + /- 342.8 kcal/day ( mean + /- SD ) . Fat intake was initially low but reached 34.1 + /- 7.9 % of total calories at final measurement . Blood glucose and lipid fractions tended to be borderline or abnormal preoperatively , and favorably changed by 12 months . Consumption of glucose- and lipid-lowering medication  significantly diminished , but each of these was still necessary in 6.3 % of the group . Correlation between body mass index and also calorie intake versus glucose and lipid measurements was highly significant ( P = 0.000 ) . CONCLUSIONS 1 ) Energy intake after operation was very low ; 2 ) Weight loss proceeded rapidly and correlated with meal pattern ; 3 ) Improvement of glucose and lipid tests was adequate but took several quarters to normalize ; 4 ) Decreased requirements for glucose- and lipid-lowering medication was significant but not absolute ; 4 ) Fat percentage of total calories exceeded 30 % at the end of the observation period , despite recommendations to the contrary
