Among 38 adolescents with overweight or obesity, participants were divided into a water group and a control group.  The water group received “well-defined messages about water through counseling and daily text messages, a water bottle, and a water pitcher with filters.”

Key findings:

  • The water group consumed 2.8 cups of water per day compared to 1.2 cups per day for the control group
  • The 6-month chnage in BMI z score was identical z= -0.1.

My take: Advice and behavioral supports to consume 8 cups of water per day are likely to fall short and do not seem to enhance weight loss.
