That about sums up what a juice fast is good for

But it's not good for dieting. Juice fasts are a bad fad and should be avoided. You'll lose a lot of water and "solids", but as soon as you have your first real meal, your body will replace both. You'll be missing almost all of the nutrients your body needs, too. I personally wouldn't recommend a juice fast for 3 days, let alone 2 weeks.
If you do decide to follow something so extreme, please consult your doctor first.
Kara, I noticed that you posted in another thread that you were upset about gaining so much weight during your pregnancy, and you were desperate to lose weight fast, and was considering fasting. I do hope you'll reconsider this, because this will not help you. Quick weight loss comes back just as quick, and usually bring friends with it

We've all been down that route before, and have learned the hard way that it never works. The best thing you can do for your health and weight is to take a more balanced approach. Go to the library and check out a good book on dieting. Or check our "Calorie Counters' forum for tips on losing weight the old fashioned way - by eating real foods, but watching portions and keeping track of your food intake. You probably need AT LEAST 1200 calories per day, maybe more. Add exercise to complete the routine, and you are on your way to your goal weight and it will stay off
Good luck!
