Will the Royal Baby Be Fat?

We know that Will and Kate’s child will be privileged. But here’s something we can also predict with great accuracy: If the kiddo will be fat. Princess Kate waving

How? A study in the journal PLOS ONE recently found that the formula used in this online calculator accurately predicts whether or not an infant will be overweight or obese as an adolescent and an adult. The calculation factors in the mother and father’s body mass index (BMI), the mother’s work status, the number of family members, and the infant’s weight at birth, and whether or not mum smokes.

His Infancy has a pretty good shot so far. Parental weight status is the greatest predictor of a child’s obesity later in life, the researchers say, and neither Will or Kate have problems in that department. One study from the U.K. found that about 77 percent of a child’s BMI is controlled by heritability. In other words, if you look like Henry VIII, Henry IX will likely follow suit. 

That is, unless you take action. Your kids don’t only inherit your DNA—they inherit your eating habits, your attitude toward exercise, and pretty much everything you do, whether or not you know you’re doing it. Follow the tips below to make sure they pick up on the right behaviors. And if you don't have a royal body, don't worry: You can reshape every muscle in your body in 82 days with Speed Shred, the new follow-along DVD series from Men’s Health!

Ban the Juice Box

In the past, kids came home from school and had a nice cold glass of milk; today, they're just as likely to toss back a sugary juice box or soda loaded with empty calories. Instead, offer water mixed with a dash of 100 percent fruit juice for flavor.

Don’t Exercise—Play

Kids playing on bikeOne in five American kids between the ages of 9 and 13 gets no exercise at all, according to the CDC. But 7 minutes of vigorous activity a day is all it takes for kids to have a lower body mass index and lower blood pressure, finds recent research from the University of Manitoba. Give your child plenty of chances to burn off energy every day by playing Pirates vs. Jedis in the yard or setting up an indoor obstacle course on rainy days. And try walking, scootering, or biking places together instead of piling into the SUV. Want even more ideas? Click here for 7 Fun Ways to Be Active with Your Kids.

Limit TV Time to 2 Hours a Day

One study of 5-year-olds found that for every hour watched above the American Academy of Pediatrics' recommended limit of 2 hours a day, a child had a 7 percent greater risk of being obese by age 30. "It's not just the sedentary time—it's all those commercials for food," says Sandra Hassink, M.D., director of the weight management clinic at the DuPont Hospital for Children in Wilmington, Delaware. A study in Pediatrics found that nearly 98 percent of food ads viewed by kids between ages 2 and 11 were for junk high in fat, sugar, and/or sodium. Says Hassink, "The counter-programming by the ads is going to be much more powerful than anything you can do, unless you're a cartoon character."

Never Give Candy as a Reward

Instead, award one point every time your child tries a new food. Ten points earns a small toy, 30 equals a movie of their choice, and 75 a kid-approved vacation destination. They'll see foreign foods as an opportunity, Shu adds. And because you dole out the points, you retain the leverage.

Eat Dinner at Home

It's great to have someone else do the cooking and wash the dishes, but if you use the local pasta joint or fast-food chain as your family caterer, your kid's health will suffer: One study found that when children eat out, they consume nearly twice as many calories as when they eat at home, plus more fat, sugar, and carbs. A meal at home with the family around the table has the opposite effect: Kids eat one and a half times as many fruits and vegetables as when they eat by themselves, and they tend to continue to make such healthy choices throughout the day, according to a Harvard study. Kid staples—mac and cheese, fries, nuggets—are typically loaded with fat and calories. But they don’t have to be. Try one of these 6 Quick Family-Friendly Recipes tonight!
