There is low to high ( majority moderate ) certainty for small improvements of unclear clinical importance in plasma glucose , triglycerides , and HDL concentrations favoring low-carbohydrate food at half of the prespecified time points .
There was little to no difference in LDL concentration or any of the secondary outcomes ( body weight , waist circumference , blood pressure , quality of life ) in response to either of the diets ( very-low- to high-certainty evidence ) .
Conclusions Currently available data provide low- to moderate-certainty evidence that dietary carbohydrate restriction to a maximum of 40 % yields slightly better metabolic control of uncertain clinical importance than reduction in fat to a maximum of 30 % in people with T2D .
Background It remains uncertain which diet is best for people with type 2 diabetes ( T2D ) .
Objective We compared the effects of dietary carbohydrate restriction with fat restriction on markers of metabolic syndrome and quality of life in people with T2D .
Effect of a high-carbohydrate versus a high--cis-monounsaturated fat diet on blood pressure in patients with type 2 diabetes.
OBJECTIVE To investigate whether blood pressure is different in type 2 diabetic patients on a diet rich in carbohydrates versus a diet rich in cis-monounsaturated fatty acids . Data on the dietary effects on these diets ' glucose and lipid metabolism have been previously published . RESEARCH DESIGN AND METHODS The study compared the effect of feeding 42 type 2 diabetic patients a carefully controlled isoenergic high-carbohydrate ( high-carb ; 55 % energy as carbohydrate , 30 % as fat , and 10 % as monounsaturated fat ) and high-monounsaturated fat ( high-mono ; 45 % energy as fat , 25 % as monounsaturated fat , and 40 % as carbohydrate ) diet for 6 weeks each in a four-center , r and omized , cross-over study on blood pressure . Twenty-one patients continued the diet they received during the second phase for an additional 8 weeks . RESULTS According to repeated- measures ANOVA , blood pressure during the last 3 days of each phase was similar after 6 weeks of the high-carb and high-mono diets ( systolic blood pressure : 128 + /- 16 vs. 127 + /- 15 mmHg , P = 0.9 ; diastolic blood pressure : 75 + /- 7 vs. 75 + /- 8 mmHg , P = 0.7 ) . However , after 14 weeks of the high-carb diet ( n = 13 ) , there was a significant increase in blood pressure compared with 6 weeks of the high-mono diet ( systolic blood pressure : 132 + /- 13 vs. 126 + /- 11 mmHg , P = 0.04 ; diastolic blood pressure : 83 + /- 6 vs. 76 + /- 7 mmHg , P = 0.002 ) . After 14 weeks of the high-mono diet ( n = 8) , the reduction in blood pressure was not significant compared with 6 weeks of the high-carb diet ( systolic blood pressure : 118 + /- 14 vs. 121 + /- 16 mmHg , P = 0.4 ; diastolic blood pressure : 71 + /- 8 vs. 75 + /- 10 mmHg , P = 0.3 ) . CONCLUSION Although the exchange of carbohydrates with monounsaturated fats may not affect blood pressure in the short term , long-term consumption of a high-carbohydrate diet may modestly raise blood pressure in type 2 diabetic patients
