My opinion:
Most people, men in paticular, seem to have an endo-meso build. Whats this? It means they tend to carry on too much weight, especially with a sedentary lifestyle, but do have the capability to be in good shape. However, without reading a lot and understanding the fundamentals of nutrition, most of these people will think its impossible to be lean. It's harder, but not impossible.
I believe it would be suit if more money was spent on educating people regarding nutrition in paticular. Excersizes are very basic, and well understood, but nutrition is over 50% of the equation, but the most people usually elaborate on it is "eat your vegetables, fruits, and avoid junk food." This seems not to work, so if we're going to have public schools (which I'm against, but thats another ballpark), then rather than spend all this money teaching sexual abstinence and other stupid subjects, I think nutrition in itself should be a required study.
1) "Government shouldn't hold kids hands"
2) "Give Up! McDonalds and other corporations have brainwashed them!"
3) "Health class teaches this, I thought?"
In brief response:
1) Are we expecting them to be able to read a nutrition chart and expect them to know everything? The education system really hasn't helped give their share of the deal by teaching kids what eating well is, what fat is, and everything. People know from what they think they know, that fats are bad, and that calories are bad. Crap like that needs to be corrected, not furthered.
2) It's better to try than assume their minds have been wrapped around Ronald McDonalds finger. The film Supersize Me seems to generate a bad vibe in one scene, but thats not true for everything. He probably went around and filmed at a bunch of classrooms, and found the one with the best response to suit his political agenda.
3) Health class teaches (from what I remember) mostly about the "Dangers posed to youth." The class is only a semester long, and it only goes briefly into nutrition.
