40,000 years ago nomadic hunters had the best diets out of anyone in the world.  They would hunt down there prey which requires a lot of sprinting.  It would usually consist of a big woolly mammoth.  A very good source for meat and protein.  Then they would have to carry the meat back to the village.  Besides that they would grow small amounts of vegetables.  This was the reason all of the people back then were in such good shape.  The Paleo Diet has been a popular idea and is being considered by a lot of people in the country.  This way of eating is more developed for our genes as well.  Eating with this kind of diet would help people be much more fit.  But eating isn't the only battle.  The proper exercise is very important as well.  Unfortunately there is a huge controversy in what kind of exercise.  Should it be a short and quick workout or a long distance run.  The way people did it 40,000 years ago was a short sprint for food and a long haul of the heavy meat.  This is a very extreme diet but it would be interesting to try.
