Aside from these minor differences, however, the two diets are much the same. Some proponents of detoxification recommend brief, intense, water-only fasts. However, a three-day fast supplemented with vegetable and fruit juices is more typical. On the day before the fast starts, you're instructed to eat lightly, finishing the day with a meal of fresh fruits and vegetables. During the fast itself, you're expected to drink 3 to 4 eight-ounce glasses of juice, preferably fresh squeezed.
Most therapists also recommend avoiding coffee and soft drinks, and getting lots of rest.
Often the entire procedure is scheduled for a weekend, when you can conserve energy and take naps as needed. It's also best to avoid vigorous exercise, although short walks or stretching are considered acceptable. Since the drop in body temperature may make you feel colder than those around you, be sure to wear extra clothing to keep warm. During the first day of the fast, you'll lose 3 to 5 pounds. That's a water loss that will come right back after you start eating again.
