I see your point, but I think that the article does give an answer to those problems, too. The solution is to incorporate changes slowly. A lot of people start extremely motivated, start exercising, eating healthy, taking fish oil, take the stars, etc., but they can't make it through two full weeks and are back to their old bad habits. So the idea is to start simple and add on this from time to time.
