What is a partial meal replacement plan?
The partial meal replacement plan is a combination of meal replacement products and food.
Meal replacement products are calorie-controlled, pre-prepared, specially formulated foods usually in the format of a liquid or a bar. On a partial meal replacement plan, you replace 2 meals a day with a meal replacement shake, bar or soup.
Most commonly, you will have a meal replacement at breakfast and at lunch and end the day with a healthy, balanced and portion-controlled dinner. You can have your food-based meal for breakfast or lunch if you prefer.
How does partial meal replacement work?
Meal replacement products are used to assist with weight loss. They contain protein, carbohydrates, fat and fibre. They are also fortified with the vitamins and minerals you would get from a nutritionally balanced meal.
We recommend replacing 2 meals with a meal replacement. This contributes approximately 400 calories to your daily calorie intake, as each meal replacement is about 200 calories. On average, you will aim to consume 1200 calories a day. Your coach will help adjust your calorie goals as you progress through the programme.
Your food-based meals will be portion-controlled, and they will follow the T plate model. You’ll learn more about the T plate model in a later lesson. For now, here’s a brief breakdown.
Your T plate
The aim is to portion your plate into sections.
Tellermodell mit Kategorien
Half of your plate is for non-starchy vegetables, such as: Salad, broccoli, cauliflower, cucumber, carrots, mushrooms, peppers, tomatoes
One-quarter of your plate is for a lean source of protein, such as 100g chicken, 2 eggs, 150g tofu or 130g fish
One-quarter of your plate is for your portion of starchy carbohydrates, such as 1 to 2 slices of bread, 1 medium-sized potato, 100g cooked rice, 100g cooked pasta
The meal should be low in fat. Your fat portion should not be bigger than the size of your thumb. You can learn more about food portioning in ‘Portion sizes and snacking’.
Snacking while on a partial meal replacement plan
You can eat around 200 calories in snacks a day. You can divide this however you’d like to, say, with one 200kcal snack or 2 x 100kcal snacks a day.
Is a partial meal replacement plan right for you?
What are your first impressions of this diet plan? Let’s say you were to start next week, once you have everything you need. How do you feel? If you feel ready to try this method, speak to your coach to create an action plan.
If you struggle to get 3 regular meals throughout the day, or you don’t have enough time to cook, this diet may work well for you.
If you struggle with hunger, the meal replacements are high in protein, so it will help keep you feeling fuller for longer.
You and your coach can agree for how long you will follow the plan. Typically, this is between 1 and 3 months, but it may be longer in some cases.
Diabetes considerations
If you take certain medications for diabetes, such as sulphonylureas (for example, Gliclazide or Glimepiride) insulin, or any other medication with a hypo risk, you may be at higher risk of hypoglycaemia. You must continue to monitor your blood glucose closely when following this plan. We also recommend that you discuss your medication dosage with your diabetes nurse or GP before you start this approach.
Where can you buy meal replacements?
Firstly, make sure that the meal replacement products you buy state that they can be used as a meal replacement. Other health and fitness shakes or bars won’t contain enough nutrients or nutrient variety.
If you’re concerned about allergies or any other dietary requirements, please talk to your coach, who will point you in the right direction. Be sure to look at individual product information.
Can you follow this plan on a budget?
Absolutely. A range of meal replacement products are available to suit different budgets.
You may find that more expensive meal replacement products come in a wider range of flavours and formats, including soups or bars.
You can also purchase ready-made meal replacement shakes, but these tend to be more expensive than powder-based meal replacements that you make at home.
When do you stop following a partial meal replacement plan?
You and your Oviva coach will agree for how long you will follow a partial meal replacement plan.
When you decide to stop, you should start by reducing 2 meal replacements a day to 1. You should continue to eat well-balanced meals and snacks that support your weight loss goals.
You and your Oviva coach will agree for how long you will follow this stage of your plan. You might have 1 meal replacement a day for 1-4 weeks before you move away completely from meal replacement products and back onto well-balanced meals.
If you gain weight during this stage, don’t panic. You can always start following the partial meal replacement plan again for a short time to help get back on track and come back to only eating well-balanced meals when you feel ready again.
Once you get back to eating regular meals, try to include food you enjoy in moderation. Studies have shown that restricting food that you enjoy can lead to overeating. This is why we encourage sticking to your healthy eating choices 80% of the time, allowing 20% of your diet to be less rigid once you have completed your meal replacement plan.
Staying active on a partial meal replacement plan
Being active during your meal replacement plan will help support your weight loss. You’ll learn more about this in a later lesson.
Activity does not have to be going to the gym or going for a run. For now, think about what kind of light activity you enjoy doing.
Do you enjoy walking in nature? Maybe you enjoy gardening and could start a new gardening project? Consider adding more of what you enjoy to your daily routine.
You can discuss your activity options with your coach.

Meal replacement tips
1: Plan ahead
Choose which meals you would like to swap with a meal replacement product. If you have trouble deciding, think about which meals you struggle to plan for.
If you think 2 meal replacements a day is too much, you could always start with 1. Once you feel ready and if you and your coach think you could benefit from it, you can increase your meal replacements to 2 a day.
2: Swap your highest calorie meal
Swapping your highest calorie meal for a meal replacement product will give you a greater calorie deficit compared to replacing a lower calorie meal and help to increase your weight loss.
3: Select suitable snacks
Low-calorie snack ideas include:
a portion of fruit
cherry tomatoes
sliced bell pepper, carrots or celery
low-calorie yoghurt
a small portion of reduced-fat cheese
10 olives (not in oil)
1 rich tea biscuit
flavoured or unflavoured rice cake
small bag of low-calorie popcorn
A small handful of unsalted nuts
4: Look after your bowel
Bloating, changes in bowel habits and flatulence (wind) can be side effects when you begin to use meal replacements.
We encourage you to drink at least 1.5 to 2 litres of water every day to help with these symptoms. Discuss with your coach how you can improve your bowel function. You may be advised to increase dietary fibre or take a fibre supplement.
5: Consider your nutrient balance
If your food-based meals are well-balanced, you don’t need to supplement with a multivitamin. You will get plenty of nutrients from fruits, vegetables and other foods.
Your coach may let you know if you need to consider taking multivitamins. If you have any concerns, please speak to them for a personalised recommendation.
