As any reader of The Shangri-La Diet knows, I attribute the obesity epidemic to ditto foods — foods that taste exactly the same each time, such as factory food and fast food. We eat a lot more of these foods today than 50 years ago or even 20 years ago.
An alternative explanation of the obesity epidemic that many people believe is too little exercise. People who deal with childhood obesity, in particular, often say the problem is too much TV, too little playground.
If kids are fat due to lack of exercise, more exercise should be a good solution. A new study shows it isn’t. It turns out that giving kids more P.E. doesn’t cause weight loss:
In studies involving nearly 10,000 children, primarily in elementary schools, none demonstrated a reduction in BMI with those who were assigned to the most phys-ed time, compared to those who didn’t have as much.
