I'm going to jump right into the idea of fasting for 6 days and the unfortunate reality that most people in our field(s) don't. 1. know how to lose weight (really) 2. know how to eat 3. know how to workout Here, if you want to try fasting, which I do recommend, give this a shot. http://www.leangains.com/ or do the Warrior diet (one huge meal a day). A 16/8 fast is great. Heck, I sometimes even do an eat-stop-eat way…
And that's what weight loss is all about. Calories in vs. calories out.
I speak from not only the obvious facts but also experience, I lost over 100lbs from January 2009 to July 2010 and got healthy in the process.
