Those teens were later also more likely to encourage their own children to diet. According to Dr. Albers, dieting among teens can encourage a negative relationship with food. She says it’s more beneficial to practice mindful eating – where the focus is on how you eat, rather than what you eat.

“It’s so important to give teens these skills at this juncture in their life and I talk to parents about tools, not rules,” Dr. Albers added.
