Abstract

Aims. To evaluate 3 strategies to reduce weight in obese families. Research design and methods. 142 obese parents and 119 obese children kept a fat-calorie restriction diet. On top of this diet, the families were randomized in a three-factorial design to one or more of three weight-loss strategies: (1) an additional diet preferring carbohydrates having a low glycemic index (dual diet), (2) financial incentive, and (3) telemonitoring of weight and physical activity. Results. All children improved their BMI-SDS by ( ) independently of the weight-loss strategy. In parents, relative losses of weight (kg) were 6.4% versus 4.0% for dual diet versus calorie restriction ( ), 6.9% versus 3.4% for with or without financial incentive ( ), and 8.0% versus 4.8% for with or without telemonitoring ( ). The weight loss after financial incentive plus dual diet plus telemonitoring was 14.4%. Conclusions. All strategies were effective in adults, in particular when combined. Children improved their BMI-SDS regardless of the strategy.
