Diet Center offers one-on-one weight loss counseling and consulting, helping clients shed pounds through healthy eating. Clients are given a choice between four programs: "Exclusively you," "Instant shape up," "Diet fast" or "21-day diet." The latter is a premium program where people will drop between 10-15 pounds after completion and continue to lose 3-5 pounds per week upon staying on the regimen. Diet Center follows three stages of weight loss: reduction, stabilization and maintenance.
