I agree with that article. I was a college athlete and have always worked out like crazy, but the only time I ever really saw weight loss was when I changed my diet (which is just no fun). One personal trainer I know said that diet is 80% of weight loss. However, like everyone is saying having more muscle will only help with metabolism so exercise is also an important to consider. Plus exercise helps tone and prevents the "skinny fat girl" as some people like to term themselves. Really it also depends on how your body reacts. There are some people that swear they lost 20 lbs by starting running, and maybe that is how their body reacted. Where as another person may lose nothing from starting to run. It is important to find balance, especially your own personal balance. Thanks for bringing this up!
