Phytoplankton
Phytoplankton is your solution to be healthy. Do your own research, I don't expect you to take my word for it.
Do extensive research to find out all you can. Use many search engines to get more results and read up.
Go to The Search Engine Station to do your research - easy place to access many search engines.
Eat vegetables and fruit throughout your day instead of junk food.
Exercise, start walking, try to do it couple times a week in order to get use to it .
Do some running after you get use to walking, don't force yourself. Increase your exercise gradually.
What goes around comes around, and when it does it gaines speed. It's true. Remember that one ?
Think about the other guy, the next guy, other people, instead of beeing concerned only about yourself.
The rewards will be greater than you can imagine.
Obviousely you're not the only one on this Planet and by far not the only one in this Universe.
Why would you think that you are the most important creature of all ? Think about it.
Don't you think that maybe, just maybe there is something or someone somwhere more important  than you ?
Everything is connected directly and indirectly. Every one of your actions can cause many other reactions.
Always try to be a good example so other people will learn from you.
Be a good element in this huge Universe, have a peaceful mind and
have a nice life.
