Does everyone eat pretty much whatever they want during stage one? I feel like I've been eating like a pig and yet I've still lost weight and feel just all around better. Are there any reasons for this?
If you really follow the rules of Stage One (lots of water, just light grazing on nuts and fruit during the day, etc.), you can eat pretty much anything for your feast and still lose weight. The reason for this is simply that if you consume less calories than your body burns in a day, you will lose stored energy (fat tissue). A typical 200 pound man requires about 2,400 calories a day to maintain a constant weight (this varies per the individual, of course)... you'd be hard-pressed to consume that many calories in one sitting, unless your feast consists of something like a block of pure lard. Of course, if you're eating unhealthy foods, the long-term consequences won't be pleasant, even if you lose a lot of weight, which is why you should be getting into the habit of eating the right foods as you progress into a paleo-correct lifestyle.
