I've been reading about the "lemonade diet" and such (visiting http://www.2healthandwellness.com/lemona... ) and it seems that is a detox plan.
Then I stumbled across what appears to be a weight loss / fat loss diet kind of thing at http://www.absixpack.com/4/detoxing.html which looks like it also involves detoxing, but claims to help you lose weight.
Can I lose weight and detox at the same time? Is that healthy? Is it bogus?

Whenever you are trying to lose weight, you should concentrate on these three things which all work together in providing a healthier and quicker weight loss goal for yourself. I have found this combination really successful in my weight loss plans. The first thing is exercising and how much you can put forth into it. The more you exercise, the more results you will see. The next thing is dieting and the calorie intake. If you exercise more, technically you could eat more? Always watch what you eat.
Now the last step in a good weight loss plan is always a good diet pill that can help you get to the end of the road. I have found Proactol which is a natural herbal diet pill to be the best around. It's an appetite suppressant along with being a fat blocker which stops up to 28% of fat you eat. Read up about it at TheWeightLossPlace.com where I saved money on it. Proactol really works well with exercising which gives you plenty of energy to perform. Along with that you diet will be affected by Proactol due to the appetite suppressant and fat blocker. If you slip up on meals, the fat blocker kicks in. It's really great to stop food cravings.
Concentrate on those three things and the combination is deadly for the fat cells in your body. Good luck and I hope this helps.

Yes you can lose weight and detox at the same time.
It's healthy when done CORRECTLY with proper support.
For me I used a nutritional product (that I now help others with) and eliminated 40 pounds in 90 days and have kept it off since Aug 2006! I'm healthier than ever and feel great.
I continue to do occasional cleanses to keep healthy and give my body a break from all the toxins in our environment.
I'd be happy to chat with you about it - no sales - just informational. Just send me an e-mail.
Good Luck
