I've been studying/researching nutrition, excercise, and general health since 2013. If you want to make a huge difference for yourself, get healthy. Start now. Get to a healthy weight! It's very important you do this, and it will pay off much later in life through decreased expenditures on hospital visits, doctors, etc. If anybody has any other ideas feel free to add them to this thread; books, youtube videos, etc.

Below are the resources I personally use and think are the most effective. There is also a lot of information on youtube. They may or may not work for you. Go Your Own Way but start now!
