What is Intermittent Fasting?

Our Intermittent Fasting plan is designed to help you to lose weight and maintain weight loss. It offers the flexibility to switch between periods of fasting and eating, without restricting your caloric intake for days in a row.

Intermittent Fasting Plan

How does it work?

Depending on your lifestyle and week schedule, there are two plans we are offering:


Alternate Day Fasting Plan - Staggers fast and feast days one after the other.

On fast days: Enjoy four OPTIFAST meal replacements as your solely food consumption of the day.

On feast days: Eat conventional meals.

Total calories intake per feast day: 1,200 for women and 1,500 for men, depending on your weight loss goal.


5:2 Plan - Alternates five feast days with two fast days.

On fast days: Enjoy four OPTIFAST meal replacements as your solely food consumption of the day.

On feast days: Eat conventional meals.

Total calories intake per feast day: 1,200 for women and 1,500 for men, depending on your weight loss goal.


Depending on your weight loss goals, after three months of either plan, you can increase the calories you consume on feast days usually 1,400 to 1,700. or move into our Maintenance plan
