This may be a satisfying answer to you but is not helpful or accurate. The whole point of the article is that we have been misled in our definition of healthy foods because of an inaccurate food pyramid promoted by the government without any real research. It has taken decades for scientists to examine the food pyramid critically and realize that it is making people obese and promoting type 2 diabetes and that avoiding fat is further compromising people’s health.
Inner strength sound good and so does self discipline but calorie counting, portion control and exercise does not yield results for many people. Talking about going to the gym every day may make a person feel self righteous but many people are caregivers,or working two jobs to make ends meet and don’t have that time or funding. Its just an easy thing to say that puts the blame on an individual with genetics that makes them especially sensitive to carbohydrates or some additional factor that we have not uncovered yet. There is good information in this article that, if more widely dispersed, could do a lot to improve the lives and health of many people in a way that eat healthy foods, in “normal proportions” and go to the gym will not.
It's ignorance. People are becoming adults and never being taught how to take care of themselves.
And, then, there are folks who keep reassuring (i.e., misinforming) these people that there's really nothing they can do about it so they should just keep doing what they're doing. "Don't learn about nutrition. Let McDonald's research it for you. Don't get off your butt and exercise, you'll just strain yourself. And, whatever you do, don't listen to people who are physically fit. They're just lucky,"
The truth is that most of these folks don't really like their fat, toilet-busting butts, but they don't know what to do about it. Unfortunately, most have never been taught how to take care of themselves. And, now, you can see that they're teaching their own children everything that they never learned themselves.
