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 .
[Favourable effect of olive oil in patients with non-insulin-dependent diabetes. The effect on blood pressure, blood glucose and lipid levels of a high-fat diet rich in monounsaturated fat compared with a carbohydrate-rich diet].
To compare blood pressure , glucose and fat metabolism after a high-fat diet rich in monounsaturated fat reduced day time systolic ( 131 + /- 3 vs. 137 + /- 3 mmHg , p < 0.04 ) and 24-hour systolic blood pressure ( 126 + /- 8 vs. 130 + /- 10 mmHg , p < 0.03 ) as well as day time diastolic ( 78 + /- 2 vs. 84 + /- 52 mmHg , p < 0.02 ) and diurnal diastolic blood pressure ( 75 + /- 6 vs. 78 + /- 5 mmHg , p < 0.03 ) as compared with the high-carbohydrate diet . Evidence of improved glucose tolerance on the high-monounsaturated diet compared with the high-carbohydrate diet were found with lower fasting blood glucose ( 6.1 + /- 0.3 vs. 6.8 + /- 0.5 mM , p < 0.05 ) , lower average blood glucose levels ( 7.4 + /- 0.5 vs. 8.2 + /- 0.6 mmol/l , p < 0.01 ) and peak blood glucose responses ( 9.9 + /- 0.6 vs. 11.3 + /- 0.7 mmol/l , p < 0.02 ) . Similar levels of fasting triglyceride , total cholesterol , LDL- and HDL cholesterol were found after the two diets
