To make a long story short, keep rolling and keep training, you'll be in better shape right quick.
To give you the long story of it... Cut out the following from your life...
1- All pork products. The pig is the most disgusting animal ever to exist, it eats its own fecal matter, it eats dead pigs, it eats living rats (gobbles them up in one bite), without having to be tricked into it (cows have eaten dead cows, but only when the dead cow is ground up and mixed in with grain feed and they are tricked into eating it).
2- All shellfish, cat-fish, snails, anything that is a bottom-feeder, etc. These things will be rich in pollutants that sink to the bottom, such as heavy metals (arsenic, lead, mercury, etc).
3- All artificial sweeteners (Aspartame aka NutraSweet is the biggest offender, not to mention a known human carcinogen).
4- All caffeine.
5- Most/all alcohol (I stopped drinking alcohol when I started training and getting serious about things).
6- Tobacco products (they raise your risk of heart disease, lung cancer, oral cancer, throat cancer, urinary bladder cancer, and wreck your cardio).
7- High fructose corn-syrup (this is a vile thing that does not belong in our food). If you are absolutely attached to soda, there are a few companies that make special cane sugar soda, with no HFCS. However these companies are rare and the soda is somewhat pricey. I would limit myself to one or two cane sugar sodas per week or per two weeks.
8- BHT and TBHQ, these are known human carcinogens and they are typically used in the embalming process for bodies. They wound up being used in food as preservatives for flavor and their consumption may lead to a mountain of problems in the short-term (headaches, migraines, etc) and the long-term (cancer/death). Some of the worst offenders for using BHT and TBHQ are frozen meal companies and candy bar companies.
