Its funny I come across this thread, I completely re-vamped my diet back in November. I know it's the worst time of year to try, but I figured if I could make it through the holidays without over-doing it, I would be able to stay on the wagon for the rest of the year. And its exactly as petepaz says: just eat healthier, smaller meals every couple hours. Its amazing what that alone will do.
I was watching a show on discovery about food production. and they were making some sort of processed snack cake and I can remember thinking " good lord! there's not a single natural ingredient in there!" so I started doing my own research on what these food additives are, and what they can do over long periods of time. Well lets just say, after a couple days of reading, my pantry was empty, but my garbage can was overflowing! I couldn't believe what some of the things were in the foods I loved to eat. This coming from the guy who thought "Organic" was for hippies, lol.
One quick example - Sodium Nitrate. Its a preservative in meat. In my case, I used to eat turkey bacon, and its used to preserve the meat and give it its pink color. Well sodium nitrate will really screw with your body's hormones, It sends a signal to your brain and your body almost completely shuts down its fat burning hormones and puts your fat storing hormones into overdrive. needless to say, the turkey bacon was the first to go.
Long story short, I started eating more fresh and whole foods, (organic wherever I can) stay away from all those packaged foods that will last for 5 years on a shelf. After two weeks of a completely revamped diet, I was feeling MUCH better, (I didn't even know that I wasn't feeling 100% all the time) had more energy, and was sleeping better. Not to mention I also lost 10 pounds, and I hadn't even started my exercise regimen! ( mind you im 5'8" and weighed 210 so the first 10 lbs come off quick)
Change your diet, eat the foods your body was designed for and you'll be amazed
