I think the article is more true than not true, but confusing and misleading in how it says it. I don't expect that if I do and exercise (HIIT or a long bike ride or run, weight lifting) that my metabolism is revved the rest of the day so I can have a free for all with my eating. I don't think any of us believe that we can eat what ever we want because we worked out in the morning. Diet is as important, if not more important, than exercise for losing weight. Reading this article reminded me of the signature line of one of our Catheites (I believe it's Pinky, but it may be Sarah) - "You can exercises until the cows come home, but if you don't control your diet, you will still be cow coming home" (something like that - but you get the idea).
