What are Meal Replacement Shakes?

Meal replacement shakes (or meal replacement drinks) are food supplements that are commonly used to completely replace a meal, snacks, or multiple meals during the day. They either come in the form of powders or ready-made drinks, and usually have a shake-like consistency.

Meal replacement shakes are commonly used for weight loss due to their lower calorie content, and the filling nature of the shakes.

For more information, we have put together an in-depth FAQ section at the end of our list of meal replacement shakes reviews, which answers questions such as 'how to use meal replacement shakes' and 'how much weight can i lose with meal replacement shakes?'.

How to use meal replacement shakes

There are some general guidelines for meal replacement shakes and how to use them in order for them to be effective. These include:

  • When mixing your shakes, use either water or plant-based milk so that you don’t add unnecessary sugar and calories into your diet.
  • Replace at least one meal or your daily snacks with complete meal replacement shakes; adding in shakes to your existing diet will just add more calories to your daily amount and potentially lead to weight gain.

Some brands do offer specific instructions so be sure to check the packaging to be sure you’re getting the most out of your shakes. Alongside exercise and a healthy diet, meal replacement shakes can be super efficient in aiding weight loss.

How do meal replacement shakes work?

high protein meal replacement shakes

The science behind weight loss meal replacement shakes centres around the energy and calorie intake of an individual's diet. The basic principles of this type of diet is to intake a lower calorie/energy content than the level of calories/energy you use in your exercise or everyday activities.

By substituting a meal (or multiple meals) with low calorie meal replacement shakes, you should be lowering your overall calorie intake. When the calorie/energy intake is low enough and the restrictions kick in, the body begins to burn fat for energy instead of the energy usually stored in the muscles. 

The science behind it can be a little confusing, but the bottom line is that by using complete meal replacement shakes properly your overall calorie intake will be lower and therefore trigger weight loss. Crucially, using meal replacement shakes as opposed to traditional dieting methods has actually been proven to be a more effective and healthier way to lose weight, as stated by Manny Noakes, Paul R. Foster, Jennifer B. Keogh and Peter M. Clifton in the Journal of Nutrition:

The effectiveness of the meal replacement program by a measure of “nutritional adequacy” thus is as sound if not somewhat nutritionally protective, compared with the conventional weight-loss program. (Noakes et al., 2004)

So if you’re serious about losing weight, then meal replacement shakes could be the best way forward, and if learning about nutrition like this sounds interesting to you then maybe it would make a great career!

How many meal replacement shakes a day?

This really depends on how much weight you’re looking to lose and how quickly. Usually, 1 or 2 is the recommended amount to lose weight healthily, although some brands (such as Almased) recommend starting their meal replacement shakes with 3 per day, replacing all meals. 

Whilst the answer to this question depends a lot on your goals, we recommend starting off slowly to see how your body reacts to the replacement meal drinks and to judge whether your diet will be sustainable.

How to make meal replacement shakes

natural meal replacement shakes

This is actually quite simple! The powdered versions usually just require a few scoops (the products will advise you on how many scoops you need per serving) mixed with water or plant-based milk to create a drink. If you want some added goodness or extra flavouring, you can blend in some fruit, cocoa powder, or flavourings such as vanilla as well.

How to mix meal replacement shakes is also simple enough: it’s recommended that you use a blender or protein shaker to ensure a smooth consistency, but you can also use a spoon or a whisk to mix them up to (just ensure thorough mixing to make sure the powder and liquid is completely blended). 

How to make meal replacement shakes taste better

Unfortunately, even the best tasting meal replacement shakes might not be to your tastes, and sometimes the consistency of the powders/shakes can be a little unappetising. Many brands do provide different flavours so trying a few different ones is a good place to start. However, due to the nature of the shakes it’s really easy to spice them up or make them more tasty!

If you have a blender then you can simply throw in fruits, berries, essences, cocoa or coffee powder, to your meal replacement shakes to make them taste better! However, be careful not to go overboard with added sugar or increased calorie levels as this will negate some of the effectiveness of the shakes.

If you don’t have a blender you can still add things like chocolate powder or coffee, and flavourings and essences - for example, vanilla, almond, mint, caramel - for better taste. Adding more milk or more water will also change the taste without adding too many more calories. 

Which meal replacement shakes taste the best?

This is a very subjective question as everyone has their own preferences and tastes, and you can easily improve the tastes of most meal replacement shakes with the advice in the previous question. While we can’t give a definitive answer, the majority of the meal replacement shakes reviews on this list have huge numbers of customer reviews as well, and many have multiple flavours, so we’re sure that one of the products on this list will soon become your favorite.

What is in meal replacement shakes?

best meal replacement shakes for weight loss

Meal replacement shakes are specially formulated with high levels of protein, fiber, essential vitamins and minerals, and have high nutritional values overall. This makes them suitable for replacing foods that would traditionally supply these essential nutrients. As Viduranga Waisundara and Naofumi Shiomi explain in their book:

Depending on the formulation, MR [meal replacements] also possess the advantage of having a low glycemic index (GI) value; low GI diets have been linked to improved weight maintenance and reduction in risk of diabetes and ocular disease...MR also tends to be nutrient dense, meaning that the posses a high ratio of essential nutrients relative to calories. (Waisundara and Shiomi, 2017, pp.258–259).

So, if you’re wondering whether using meal replacement shakes for weight loss is a healthy way to go, rest assured that when used properly they can be effective for short term weight loss and maintaining a healthy diet while you do so.

The majority do use lactose powder or dairy products which adds some sweetness as well as being a binder, producing the milkshake consistency once mixed. This is something to bear in mind if you have intolerances; luckily there are dairy-free meal replacement shakes available.

Similarly, some powders use certain types of sweeteners or have added sugars which won’t be suitable for diabetics (for example, maltodextrin), so be sure to check ingredients if there is something that you need to avoid.  

What to look for in meal replacement shakes?

There are a few key factors in the best meal replacement shakes that will ensure their effectiveness, which include:

  • Low calorie content per serving
  • Low sugar content per serving
  • High protein per serving
  • Added vitamins, minerals, and nutrition to ensure your diet remains healthy 
  • Higher fibre content (if possible) as this will keep you fuller for longer
  • Flavours - different flavours will help keep your meal replacement shakes interesting, helping you to stay motivated on your diet
  • Powder or ready-made meal replacement shakes - this is a personal preference as ready-made options cut out the time needed to make them!

How much weight can you lose on meal replacement shakes?

top meal replacement shakes uk

Unfortunately, there is no definitive answer to this question either, but before that puts you off you should know that there have been numerous studies on the effectiveness of meal replacements, and the general scientific consensus is explained by Manny Noakes, Paul R. Foster, Jennifer B. Keogh and Peter M. Clifton once again:

In most studies, meal replacements resulted in a greater weight loss than conventional diets, even when professional nutritional support was incorporated into the program.(Noakes et al., 2004)

How much weight you can lose with meal replacement shakes is really dependent on you and additional factors which include your diet, exercise, commitment, and the length of time you incorporate healthy meal replacement shakes into your lifestyle.
