@crusader8463: "But anyone that has reached a point in their life that they are terribly out of shape it's most likely due to a sever emotional and/or psychology reason"
What are you basing this on? Cause it sounds like a load of fucking bullshit. Most people are hugely over weight cause they eat too much fucking food. In most developed and developing society's we can buy huge amounts of fatty shitty food for fuck all. And it tastes good so people eat too much of it. Not every fat man has to have an tragic back story, some of them just like to eat all pies and wash them down with 10 pints 4 nights a week. In fact, most fat people I know are pretty fucking jolly about the whole thing. You really are making a sweeping generalisation based your personal struggle with weight gain.
In fairness though, that guy saying that all people need to do to stay in shape is walk for 15 minutes a day, is so far away with the fairies that he coudln't see reality from the top of Pixie Mountain using a pair of enchanted binoculars.
Both of ye are discounting genetic factors, the mother's diet during pregnancy, the effects of childhood obesity and the fact that some where in the back of the brain where the monsters live there's a voice thtat tells you to eat everything you can becasue tomorrow you might have to starve.
Oh, as regards to your original post, of course the people selling you things are lying to you. This applies to everybody, everywhere at every point in the history of the world.
