OPTIFAST® by Nestlé health science

Successful Results for Over Two Decades

INTERVENT/WM utilizes OPTIFAST® – a medically supervised weight management program that closely monitors and assesses progress towards better health and emotional well-being.

The 26-week program consists of:

  • A full meal replacement plan
  • An easy transition to self-prepared ‘everyday’ meals
  • Comprehensive education
  • Ongoing patient support

OPTIFAST® has been successfully used in Canada for more than 20 years to help overweight and obese patients obtain a healthier weight and BMI. The module comprises a high-protein, low-caloric meal replacement plan and several detailed support functions for those looking to lose excess weight.

Smart. Healthy. Easy.

Beyond a smart, healthy and easy to follow meal plan, INTERVENT/WM also includes:

  • Metabolic rate testing
  • One-on-one coaching
  • Fitness tracking
  • Online challenges.

The OPTIFAST® program creates an atmosphere of support, accountability and accomplishment when milestones are clearly identified and celebrated upon completion.
