Find a meal replacement for your routine
Meal replacement products provide a convenient, portion-controlled alternative to a conventional meal, with options including powders, shakes and other ready-to-use formats. Depending on the product, they can provide protein, carbohydrates, fats, vitamins and minerals within a measured serving.
Formulas vary considerably, so compare calories, protein, fibre, vitamins and minerals, serving size and preparation instructions when choosing. It is also important to distinguish products specifically formulated as meal replacements from ordinary protein shakes, as they are not necessarily nutritionally equivalent.

How to choose a meal replacement
Check calories per prepared serving
Compare the energy provided by the product as you will actually consume it. If a powder needs to be prepared with milk or other ingredients, these can change the calories and nutritional profile of the finished serving.
Compare protein
Check how many grams of protein are provided by a complete serving. Protein contributes to the growth and maintenance of muscle mass, but the amount can vary considerably between meal replacement products.
Look beyond protein alone
A meal replacement and a protein shake are not necessarily the same thing. Compare carbohydrates, fats, fibre, vitamins and minerals alongside protein to understand the wider nutritional profile.
Check vitamins & minerals
Many meal replacement formulas contain a range of added vitamins and minerals. Check which nutrients are provided and their amounts or Nutrient Reference Values per serving.
Read the preparation instructions
Some powders are designed to be mixed with water while others may specify milk or another liquid. Follow the individual preparation instructions, as this affects the nutrition of the finished meal.
Compare cost per meal
Divide the pack price by the number of complete recommended servings for a useful value comparison. Pack weight alone can be misleading when scoop and serving sizes differ.
Meal replacements and weight management
Portion-controlled nutrition
A measured meal replacement can make the energy and nutrient content of a meal easier to track than preparing a meal without measuring its ingredients. Check the calories of the complete prepared serving when planning it into your diet.
Weight control meal replacements
Certain products are specifically formulated as meal replacements for weight control and must meet particular compositional requirements. Where the relevant conditions are met, replacing meals within an energy-restricted diet with qualifying meal replacements can carry authorised weight-control claims.
Your overall diet still matters
A meal replacement is only one part of your overall food intake. Changes in body weight depend on your overall energy balance over time rather than simply whether one particular meal comes from a shake or conventional food.
Follow the individual product
Products can have different intended uses and serving instructions. Follow the directions on the individual label rather than assuming every meal replacement should be used in the same way or for the same number of meals.
Meal replacement vs protein shake
Meal replacements
Meal replacement products are designed to provide a more complete nutritional serving than protein alone and can contain protein, carbohydrates, fats, fibre, vitamins and minerals. Their exact composition depends on the individual product.
Protein shakes
Protein powders are primarily used as a convenient source of dietary protein. Although they can contain additional nutrients, an ordinary protein shake should not automatically be treated as nutritionally equivalent to a product specifically formulated as a meal replacement.

Meal replacement questions
What is a meal replacement?
A meal replacement is a product intended to replace a conventional meal with a measured serving. Depending on the product, it can provide protein, carbohydrates, fats, fibre, vitamins and minerals in a shake, powder or other convenient format.
Are meal replacement shakes good for weight loss?
Some products are specifically formulated as meal replacements for weight control and can be used within an energy-restricted diet according to their directions. Weight loss still depends on overall energy balance, so a meal replacement should not be viewed as something that causes weight loss independently of your wider diet.
What is the difference between a meal replacement and a protein shake?
A protein shake is primarily designed to provide protein, whereas a meal replacement can be formulated to provide a broader nutritional profile including protein, carbohydrates, fats, vitamins and minerals. Always check the individual product rather than assuming the two formats are interchangeable.
How many calories are in a meal replacement shake?
There is no single calorie amount because formulas and serving sizes differ. Check the nutrition information for the complete prepared serving, particularly if the powder needs to be mixed with milk or another ingredient that adds calories.
Do meal replacements contain protein?
Many do. The amount varies between products, so compare grams of protein per complete serving alongside the rest of the nutritional profile. Protein contributes to the growth and maintenance of muscle mass.
Can I replace every meal with a meal replacement shake?
Do not assume a product is intended to replace every meal. Meal replacements have different formulations and directions, and products designed for total diet replacement are a distinct category. Follow the instructions supplied with the individual product.
Can I use whey protein as a meal replacement?
An ordinary whey protein powder should not automatically be treated as a meal replacement. Protein powders are primarily designed to provide protein and may not provide the broader balance of energy and nutrients found in a product specifically formulated as a meal replacement.
How do I choose a meal replacement?
Compare calories, protein, carbohydrates, fats, fibre, vitamins and minerals per prepared serving, as well as flavour, preparation instructions, servings per pack and cost per meal. Also check whether the product is specifically formulated for weight control if that is your intended use.
