Partial Meal Replacement Plan

OPTIFAST products are foods for a low calorie diet to reduce weight, suitable both for total meal replacement or as a replacement for individual meals.

Why Choose this Plan?

Our Partial Meal Replacement Plan is our most flexible option.

You create your own plan by deciding how many conventional meals you want to replace each day with OPTIFAST meal replacements. The more meals you choose to replace, the more weight you will lose.

Once you have achieved your weight loss goals you can move into Maintenance. A program of regular light exercise enhances well being and therefore the likelihood of success.


How it Works:

The level you choose depends on your weight loss goals and lifestyle needs.

Intense Level: where appropriate, we encourage people to start with this Level as this is where the greatest weight loss occurs. You can choose up to 3 OPTIFAST products a day combined with one self-prepared, low calorie meal (1200-1500 calories/day)

Active Level: If you would like to include two conventional food, low calorie meals and are happy with a more gradual weight loss, you can choose to replace either 1 or 2 meals each day, consuming 1 or 2 OPTIFAST products.Daily goal increases to 1,400 to 1,700 calories.

You can also move between levels as your goals or lifestyle needs change over time

Partial Meal Replacement Bundles

OPTIFAST offers a range of bundles to suit a 2 week, 4 week or 8 week supply on the Partial meal replacement plan.

As you adjust to your new plan this should settle down. If you experience persistent, severe or worrying symptoms, we advise you to seek advice from your GP.

These levels might be more suitable for people who require less calorie restriction to start with.

Your calorie-controlled or low-calorie meal should be around 350 calories. Aim for 1 serve or ¼ of your plate to be protein (100g meat or chicken, 130g white flesh fish, 2 eggs or 150g tofu), 1 serve or ¼ or your plate to be grains (2 slices of bread, 1 cup cooked pasta, ¾ cup of rice or 1 medium potato) and fill half the plate with low starch vegetables or salad. You can also include 1 tbsp of a sauce or dressing. This plate concept will help to keep your meal under 350 calories.Alternatively, check out the calorie- controlled recipes in the blog of the website.
