Bottom Line: The objective of the study is to compare the effectiveness of low-carbohydrate diets and weight loss for increasing blood levels of large HDL particles at 1 year.Changes in HDL cholesterol concentration were modestly correlated with changes in large HDL particle concentration (r=0.47, p=.001).In conclusion, reduction of excess dietary carbohydrate and body weight improved large HDL levels.

ABSTRACT
Depressed levels of atheroprotective large HDL particles are common in obesity and cardiovascular disease (CVD). Increases in large HDL particles are favourably associated with reduced CVD event risk and coronary plaque burden. The objective of the study is to compare the effectiveness of low-carbohydrate diets and weight loss for increasing blood levels of large HDL particles at 1 year. This study was performed by screening for body mass index (BMI) and metabolic syndrome in 160 consecutive subjects referred to our out-patient Metabolic Unit in South Italy. We administered dietary advice to four small groups rather than individually. A single team comprised of a dietitian and physician administered diet-specific advice to each group. Large HDL particles at baseline and 1 year were measured using two-dimensional gel electrophoresis. Dietary intake was assessed via 3-day diet records. Although 1-year weight loss did not differ between diet groups (mean 4.4 %), increases in large HDL particles paralleled the degree of carbohydrate restriction across the four diets (p<0.001 for trend). Regression analysis indicated that magnitude of carbohydrate restriction (percentage of calories as carbohydrate at 1 year) and weight loss were each independent predictors of 1-year increases in large HDL concentration. Changes in HDL cholesterol concentration were modestly correlated with changes in large HDL particle concentration (r=0.47, p=.001). In conclusion, reduction of excess dietary carbohydrate and body weight improved large HDL levels. Comparison trials with cardiovascular outcomes are needed to more fully evaluate these findings.

Figure 4: Predicted increase in large HDL level at 1 year according to projected carbohydrate intake and weight loss

Mentions: In linear regression modelling, the strongest independent predictors of absolute changes in large HDL levels at 1 year were 1-year changes in dietary carbohydrate intake (as a proportion of calories, p < 0.001) and changes in body weight (percent weight loss, p=0.034). After accounting for these two factors (r=0.43, r2=0.19), the effects of 1-year changes in dietary intake of calories, sugars, protein, total fat, saturated fat, cholesterol, and fiber were each non-significant (p>0.05), as were changes in waist size and exercise. The 1-year level of large HDL (mg/dL) was closely predicted (r=0.84, r2=0.70, p<0.001) by accounting for the baseline level of large HDL along with the carbohydrate intake and weight loss. To further illustrate this relationship and facilitate clinical interpretation, Figure 4(Fig. 4) demonstrates predicted 1-year increases in large HDL.
