What is a Low Calorie Diet?

Partial Meal Replacement

You can create your own weight loss plan by deciding how many meals a day you’d like to replace with our OPTIFAST meal replacement products. The more meals you replace, the more weight you can lose

How does it work?

Intense Level - 3 Week Plan

We encourage people to start with this Level as this is where the greatest weight loss occurs.

  • 3 Optifast meal replacements + one self-prepared low-calorie meal per day
  • Total calories intake per day: stay between 1,200 and 1,500 kcal


Active Level - 5 Week Plan

For a more gradual weight loss journey.

  • 2 Optifast meal replacements + 2 conventional low-calorie meals per day;
  • Total calories intake per day: stay between 1,400 and 1,700 kcal


Once weight loss goal is achieved, move into Maintenance plan.

A program of regular light exercise enhances wellbeing and therefore the likelihood of success.
