No, meal replacements are not essential or necessary. Many customers have lost significant amounts of weight by using Factor4 to reduce portions sizes. Many customers have lost weight without changing what they eat. However, meal replacements will accelerate weight loss.
For those customers who desire to lose weight aggressively, up to 1 pound every 2 days, they need to use Factor4 for a meal replacement at least once a day. Some customers take two meal replacements a day in the beginning to accelerate weight loss. We know of one doctor who took meal replacements instead of food for one year and lost over 300 pounds, reducing his weight from near 500 pounds to 190 pounds.
