Michelle Obama says that the surge in childhood obesity in the United States is nothing short of a public health crisis. One in three children is overweight or obese, and the First Lady says many are on track to live shorter lives than their parents as a result. She's making the issue her personal cause this year and will announce details of her campaign in the next few weeks.

11-year-old Dawson MacKay has been battling obesity since the age of eight. He's become a youth advisor to the Alliance for a Healthier Generation.

Dawson plays soccer, basketball and wrestlesand both his parents are nutritionalists, but despite this he is still overweight.

He says .. "I was pretty disappointed in myself - my parents kept telling me I had to lose some weight, my goal is to lose about 10 lbs by the end of the year."
