Purpose: To assess the effect of 1 week of consuming a placebo "energy drink"compared with a week of drinking regular water on daily physical activity in obese children participating in a weight reduction multidisciplinary program. Methods: Seventeen prepubertal (age = 128.7 [26.6] m) overweight and obese children (7 females and 10 males) participated in the study. Participants received 7 bottles ofmineral water per week for 2 weeks. Different types of information were randomly provided regarding the drink consumed in each week: Standard (water) versus deliberate positive information (presumed energy drink and placebo). Daily step count was measured using pedometers and compared using paired t test. Results: After consuming the placebo drink, children demonstrated a significantly higher average daily step number (10,452 ) comparedwith the days they drankwater (8168 , P < .005).This differencewas attributedmainly tomale participants.Conclusion: The use of placebo in the form of deliberate positive information was associated with a significant increase in real-life physical activity in overweight and obese children, especially in boys. Positive informationmay be used to encourage childrenwith obesity to enhance daily physical activity and energy expenditure.
