Comparison Of Two Nutritional Interventions In Obese Families

Nutritional interventions for obesity have rarely been used for the treatment of families and often work unsatisfactorily in the long term. The objective of the present study was therefore to compare the efficacy of a conventional restricted calorie diet with that of a combined diet – fat reduction plus preference for food with low glycaemic index – in the treatment of obese families over a period of 12 months.

110 families with at least one obese parent and one obese child took part. At the start of the study, the parents (n = 144) had a BMI of 33.3 ± 5.4 kg/m² (mean and standard deviation). The corresponding BMI for the children (n = 119) was 2.03 ± 0.56 kg/m². The subjects were randomised by family to the two diet groups. After 12 months, the weight loss of the adults (7.0 %) in the dual diet group was markedly greater than that in the restricted calorie group (2.9 %), as the subjects in the dual diet group achieved a greater in both energy uptake and – surprisingly – fat uptake. Neither of the diets was effective in children.
