Was there any specific reasoning behind choosing a 21-day weight-loss plan?
The 21-day weight loss plan is designed to offer the best weight loss opportunity. It’s strict and designed to kick-off the weight loss program with three weeks that should produce encouraging weight loss results — about three pounds per week. Most people notice a number of exciting health improvements during this time such as an increase in energy, better sleep and increased mental performance. It often takes about three weeks to begin experiencing significant health changes.
