When is fasting dangerous?

Fasting is a great jumpstart to a healthy lyfestyle change. pick a day and fast for about 7-10 days no longer or your body may go into shock but drink cold water and and if in need of some energy grab some rasberrys/blueberrys (no high sugar fruits) and snack on that other, then that water or a healthy shake is ok liquid liquid liquid, thats what a fast basically is. you just might lose that 4lbs but when the suggested days are up ease back into food with soups and veggies! good luck. (ps: all based on your health, if you get dizzy stop and fuel up!)

people do fast for one day normally, for more than on day, dont fast full, take milk and fruits whoel day or eat just once a ady… it can get dang. if you r nt taking anything like not even water and all and its more than a day

Yes, the best to way to do de-tox fasting is to drink plenty of liquids, especially juices. Natural juices, that is - not artificially flavored and sweetened. Drink small amounts throughout the day. Stop if you start getting dizzy.

People are different - me, I get awfully irritable if I go without solid food. Others I know can fast (with fruit juices and other liquids) for 2 or 3 days.

Longer than that, and the expert advice is always that you should be ‘under medical supervision’.
