Are Meal Replacement Shakes Effective For Weight Loss?

Meal Replacement Shakes for Weight Loss

This article will discuss how meal shakes can successfully support weight loss, and what to look out for - or avoid - in a meal replacement shake to reach those all-important weight loss or toning goals.


What are Meal Replacement Shakes?

Meal replacement shakes are high protein, nutrient dense drinks that can help achieve weight loss goals as they keep you feeling full while consuming fewer calories. 
Because of this, nutrition shakes have risen in popularity and there are now many shake options to choose from. However, these meal shakes can vary greatly in their quality and quantity, largely in terms of the ingredients they use. More on this below!

Losing Weight with Meal Replacement Shakes

There are many meal replacement drink plans that can only succeed in the short-term. This is because some shakes contain only a low quantity and quality of nutrition. They may also contain some synthetic ingredients and be overloaded with sweeteners.
The quality of the meal replacement products is an important consideration as they can vary significantly. It’s not simply about a low-calorie diet alone, it’s about where those calories come from.

An average person requires at least 50g of protein a day to preserve muscle mass whilst losing weight. So it is crucial to choose a meal shake that is high protein in order to maximise weight loss potential.

It is possible that some shakes may even do more harm than good for the body. This is because they are not made with ‘real food’ ingredients and are low in fibre or other essential nutrients.
Compare this with a high quality shake plan that is taken alongside a healthy eating and exercise regime and you are much more likely to be set up for long-term weight loss success.

Other Benefits of Meal Replacement Shakes

Avoid Unhealthy Meals

It can be all too easy to raid the fridge for easy, convenient food such as ready meals when you arrive home from a long day at work. Having a meal replacement shake to hand can avoid these mistakes that can so easily derail a weight loss plan.
There are a hundred of more ways to prepare meal replacement shakes that taste great and fill you up for hours - so there is no need to compromise on taste either.

Protein and Glycaemic Index 

Nutrition shakes are nearly always high in protein, and usually contain at least 20g of protein per serving. Protein is the most satiating macronutrient - meaning that it controls hunger for longer than carbohydrates or fats. Consuming enough protein at each meal every day is key to achieving and maintaining a healthy body weight.
Meal replacement shakes also have a low glycaemic index (GI) due to their protein content. This means they release sugar into the bloodstream more slowly than, for example, simple carbohydrates and sugar in snack foods.
Whenever you consume foods such as fruits, vegetables, whole grains and meal replacement shakes that are low GI, you are helping to support your weight loss goals as these foods help to curb appetite for longer.

Nutrient Density

Nutrient density is a measure of how much nutrition you get per serving or per calorie eaten. Meal replacement shakes often provide a high ratio of nutrients to calories, meaning they are nutrient dense. Our traditional diets are often high in nutrient-poor foods such as refined carbohydrates or fried and high fat foods - meaning people are often lacking in many essential nutrients in their overall diet.
For example, one 35g serving of BodyFuel provides 27g protein from naturally sourced, high quality crushed brown rice and peas, and all 30 essential nutrients in just 140 calories. On the other hand, a croissant is 200-300 calories but will only provide empty calories from saturated fat and sugar with no other significant nutrients.

Behavioural Changes

Aside from the nutritional benefits, meal replacements simplify weight management by allowing you to just focus on one or two other meals per day. A few ways they can help you achieve your goals include:

✔ Increased compliance - meal replacement provide reduced barriers to dietary adherence such as the temptation to indulge in unhealthy foods.

✔ Easy to estimate calories - meal replacements are an easy, precise way to keep track of how many calories you are consuming.

✔ Help fill nutrition gaps - cutting back on calories can make it more difficult to obtain the required nutrients. Meal replacements can help fill gaps in vitamin, mineral, protein and fibre intake.

✔ Easy to self-monitor - recording dietary intake helps people become aware of their food-related behaviours and make positive changes easier.


Are Meal Replacement Shakes Good For You?

There certainly aren’t a lack of options when it comes to meal replacement shakes on the market. However, not all meal replacement shakes are built alike.

Quality is a key differentiating feature; during processing, minerals and fibres are sometimes removed, and sugar or other artificial ingredients such as fillers and binders may be added. This may negate any positives of consuming the protein and as such, it is always key to check the ingredients on the label and ensure there are no chemical preservatives, or artificial sweeteners on the list.



Individuals with underlying health conditions, or taking regular medications, must check with their doctor before starting a meal replacement diet. If you’re pregnant or breastfeeding you should consult your healthcare professional before you start using meal replacement products. If you have food allergies it’s important to ensure the foods don’t contain ingredients you’re allergic to.
