I can speak to that, Adam.
It's Dr. Tom Warshawski from the Childhood Obesity Foundation. I'm a pediatrician who actively treats children who are overweight and obese.
You are right that the trajectory begins early in childhood. The major driver for excess weight gain is dietary, and that is affected by socio-economic status.
Again I would say that all governments have to be especially careful with their funding. Low-hanging fruit is to restrict the marketing and restrict the appeal of these unhealthy foods and beverages to kids, but then also to optimize their ability to be physically active and to allow them to consume healthy food and develop preferences for it, as Ms. Webb said.
It is very important to begin early. I think, though, that the major driver for excess weight gain is the food that we eat. The American guidelines reflect American reality in terms of the politics. They will not implement widespread policies, such as restricting the marketing of unhealthy foods and beverages to kids; they are focused on individual behavioural choices. That's the first part of their guidelines. Then they step up to medications and then finally to bariatric surgery.
In Canada we have a unique opportunity. As I said, we are poised to implement a unique opportunity to diminish the role of marketing and diminish the appeal of the unhealthy foods and beverages that are driving, in part, the obesity epidemic.
