After years in the practice of obesity medicine, helping people lose excess weight, I'd say the thrust of the article is correct. The main key to successful (that is, sustained) weight loss is modifying food intake. Not for nothing do we call this "lifestyle modification", we should never underestimate the effort and courage it takes to adhere to the better plan. Thing is one can never exercise enough to "burn off" the tremendous calorie intake most people are subject to. After all around 75-80% of energy expenditure occurs in the resting state, only 20-25% is ordinarily attributable to physical activity. However I fully agree with the article that exercise is far from useless, certainly can contribute to well-being and has many indirect benefits that assist in long-term maintenance of decreased body fat content. Of course none of this is really new, it's been established wisdom in obesity treatment circles for a long time. "Getting in shape" is hardly a trivial project as it requires commitment, determination, knowledge and support. Maintaining the benefit of hard won weight loss is not free, the price is eternal vigilance.
