That is exactly the nutrition advice that has been promoted in various government and school health programs for decades: eat what you like, just do X amount of exercise and you'll be fine. Calories in, calories out.
The article goes into some detail about this, mentioning that a great deal of that research was funded by companies that make sugary drinks and other high-calorie food.
