On paper, the statistics are shocking enough: the obesity rate for teens has tripled over the past 25 years and with this increase an average weight, type 2 diabetes, once unknown in young people, is now diagnosed in 45 percent of all new cases involving children or teens. Medical experts fear that high blood pressure and heart disease could become increasingly prevalent among young adults, making this generation of teens the first to have potentially poorer health and shorter life spans than their parents.

Seeing a young person you love struggle with overweight or obesity in the sensitive pre-teen or teen years is painful, frustrating and alarming — from watching them deal with cruel remarks to seeing them on the sidelines in sports or social events or knowing that they face significant health risks even in young adulthood. Maybe you’ve nagged or dropped hints or taken your child for medical help or sent him or her to weight loss camps — all to no avail.

Doctor Kathy McCoy, author of “The Teenage Body Book,” explains how you can help your teen lose weight and feel better!

• Put the emphasis on good health, not weight, and make it a goal for the whole family. Teens hate being singled out and criticized. Approaching this from a “YOU need to lose weight!” point of view will guarantee a battle of the wills. Instead, ask for your teen’s help in making an action plan to promote better family eating and exercise habits.

• Have real family meals at least once a day and encourage your teen to eat what the family eats. Frantic family schedules have equaled fast food or processed, prepared food dinners — and expanding waistlines. With real, home-cooked meals, you can better control calories, fats, sugars, sodium and other nutritional issues.

• Look at and discuss all of your less than ideal eating behaviors. Maybe your teen craves junk food when she’s bored and watching TV. Maybe you dive into high calorie comfort food when you’re angry or frustrated. Pay attention to the difference between physical and emotional hunger. Discuss all this with your family — and come up with ways to comfort or reward yourselves that have nothing to do with food.

• Make it convenient for everyone in the family to eat breakfast. Advance planning can help: fresh fruit and yogurt in the fridge, whole grain bread and cereals in the pantry, and encouraging all to get up and get going early enough in the morning to grab a bite. Those who don’t eat breakfast tend to overeat during the rest of the day, especially in the evening

• Get your family moving. Trying to motivate an overweight teen to go to the gym can be frustrating and non-productive. Schedule exercise into your family routine: a family walk or bike ride after dinner doesn’t have to cut into homework or leisure time too dramatically — and the exercise is good for everyone.

• Become smart, skeptical consumers: There are no weight loss miracles. Help your teen to avoid quick fixes. The weight didn’t come on overnight and it can’t be lost — for good — overnight either. The goal should be health improvement with a slow, steady weight loss of no more than two pounds a week. The loss can add up to more than 100 pounds in a year — and weight lost slowly as one changes one’s eating and exercise habits is more likely to stay off.

• Make a vow — together — to enjoy a full and healthy life now. You don’t have to wait until you or your teen is slim to do this. With good health as your top family priority, you can feel better starting today. Good nutrition, regular exercise and the feeling that “we’re all in this together” can make a positive difference for everyone in your family.
