Well there isn't really a worse or best weight loss program, all of them work to an extent. I believe it's just the way things have been processed and the technologies in our society that has made the world lazier and fatter. like Annagail said, we used to be way more active but now everything we do has pretty much been automated. That is one reason why people are gaining weight. Another reason is food choices and inconvenience of time, etc. I have a little bit of knowledge on proper nutrition, i'd love to share it with you lovely people.
