Is it a bad idea to fast for 1 month on just vegetables and water? will my body get enough vitamins etc...?

Fasting: This is a repeat of what I have said before. My philosophy is that the best way to lose weight is not by fasting, but by changing your lifestyle to a healthier one. You don't need a drastic diet. Make small changes. Eat the right portions, eat 3-5 small meals a day, cut back on carbs and sugars, increase lean protein/veggie/fruit/water intake, and start doing some cardiovascular exercise.
