Hi James,
The people that did it just did it for one day. The one that made it up lost 3 pounds and the other lost 2 they continued to lose after they stared back on the regular Atkins.I don't think you have to use Atkins products. The first girl that posted it was so tired of her stall she just made it up she added the Calories and Carbs and it came out to 4 shakes and 3 bars. Like I said I haven't tried it but if I stall I sure am they said they were never hungry. Pat S
