The raw foods diet does have the capability to do marvelous things for an individual's weight and health. You will have more energy, be more alert, and not have to wash nearly as many dishes!
It is not an easy thing to do though. I was a raw foodist for about 8 months, and just stopped and went back to being a vegetarian about 2 months ago. Despite the fact that I felt healthier while raw, I had to start eating cooked foods again because I have an addiction to food (Not bad stuff, just bread, mashed potatoes, melt-in-your-mouth asparagus,etc.) and I need to work that out to be successful on a raw food diet. It takes a lot of dedication to maintain that dietary lifestyle. You have to give up anything that is cooked, which is just about everything aside from any fresh fruits and vegetables you consume, and salads (with no cheese, croutons, salad dressing, etc.) It is a big commitment, and requires a lot of will power.
Out of curiosity, what does your current diet consist of? Are you a vegetarian already? The transition may be more difficult if you have to give up meat and anything cooked all at once.
The transition phase may send your body into a little shock anyhow, because eating raw will detoxify you from all of the cooked, processed foods you normally eat. The theory behind this is that eating raw provides your body with better material to build (muscle, tissues, etc.) with, and your body is always repairing itself, so for a while after beginning raw, your body is going to break down all of your inner material and rebuild it with the better stuff. I personally got very tired, and would fall asleep very early for a few weeks, and my alarm wouldn't wake me. This did pass though, and I did feel spectacular after the initial detox.
I hope that this post isn't giving you a negative opinion of the raw food diet, it really can help, I am just trying to be honest and prepare you for what could happen. It really is amazing to think about how smart our bodies are, and how exciting it is to be regenerating your insides with higher quality nutrients.
There is a website that I frequented often while raw. It can be found at: www.living-foods.com
. This site will explain in better detail the information I provided in this post, they have lots of articles on raw foods, and also a bulletin board where you can post messages. Their community is very active, perhaps more active than this board. The folks at living-foods are very nice and supportive. They tend to be on-line more during the week though, so if you don't hear from anyone 'til Monday, don't feel offended.
I hope this helps. I am planning to start raw again very soon, so maybe I'll see you on the boards.
Best of luck!
