For rapid weight loss, we recommend the Level 2 ‘Rapid’ program (2 shakes per day) for 12 weeks, or until you reach your weight loss goals. Once you have achieved your goal weight, or you’ve reached 12 weeks on Level 2, you can progress to the Level 1 ‘Steady’ program for a slower, more steady rate of weight loss. You can maintain the Steady program for as long as you like – for maintenance, or until you reach your ideal weight goal.
