Summary

Background: Lipid lowering response to weight loss in subjects with genetic hyperlipidemias and overweight or obesity and its effect on cholesterol metabolism has not been studied. Objective: To explore the effects of weight loss on lipid values and cholesterol metabolism, by measuring circulating non-cholesterol sterols, in overweight or obese subjects with genetic hypercholesterolemias. Design: The investigators conducted a 6-months weight loss intervention in subjects with the diagnosis of familial hypercholesterolemia (FH) or familial combined hyperlipidemia (FCHL), body mass index \>25 kg/m2, steady weight (±3 kg in the last 3 months) and absence of lipid lowering drugs in the previous 5 weeks. They were advised to follow a hypocaloric diet with a deficit of 600 kcal (30% fat, 15% protein, and 55% carbohydrates) per day as calculated from the person's resting energy expenditure and activity level. Anthropometric data, biochemical analysis including lipids, apolipoproteins and non-cholesterol sterols were evaluated at baseline, 3 months and 6 months.

Conditions

• Familial Hypercholesterolemias
• Weight Loss
• Familial Combined Hypercholesterolemia
• Obesity

Interventions

Type	Name	Description
BEHAVIORAL	Weight loss and dietary intervention	The weight loss intervention had a total duration of 6 months. Each participant's caloric prescription represented a deficit of 600 kcal per day as calculated from the person's resting energy expenditure and activity level using the Harris-Benedict equation. In general, prescribed energy intake was between 1200 kcal and 1600 kcal/day. Dietary composition consisted on 50-55% of carbohydrates, 15-20% of protein and 30% of fat and included a wide variety of foods typical of a Mediterranean diet. Patients were also provided with recipes and shopping counselling to improve intervention compliance and to achieve the weight loss goal. Individual consultations with a nutritionist were performed twice a month to motivate the weight loss and reinforce the intervention.
