Convenient nutrition options like meal replacement and protein shakes have become extremely popular, lining the shelves of the supermarkets and constantly appearing on social media. But what exactly is the difference between them? We’re here to help you understand the benefits of each, and when exactly you should reach for them. Are you looking to lose weight, save time, hit your protein goals or simply hit nutrition goals? Keep reading to discover which shake is more your style. Meal replacements or protein shakes, lets get in to it:
What are meal replacements?
Meal replacements are convenient nutrition options that are designed to replace an entire meal, giving you a balance of macro nutrients (carbohydrates, proteins, and healthy fats) and micro nutrients (vitamins and minerals). They typically come as a ready to drink shake, bar, or powder and usually contain 200-400 calories and 15-30g of protein. With all the ingredients you need to feel full and fortified with vitamins and minerals, meal replacements are a handy option for busy lives. They provide a convenient, healthy meal at times when the other options may not be suited to your nutrition goals.
What are protein shakes?
As opposed to meal replacements, protein shakes are not designed to replace full meals. Rather, they are made to boost protein intake specifically, helping you reach certain nutrition goals alongside a full day’s eating. They tend to come in powder form (whether whey, casein, or vegan), or ready-to-drink bottles you can buy straight from the supermarket. Protein shakes are less calorie dense than meal replacements, only containing around 80-150 calories, but are still packed with 15-30g of protein. They contain minimal carbs and fats, and often no added vitamins, so make sure you’re getting these from other sources in your day’s meals.
Key differences between meal replacements and protein shakes
When comparing meal replacements and protein shakes, there are a few key differences to note. Here’s a handy overview of them:
| Meal replacements | Protein shakes | |
| Purpose | Replace a full meal | Supplement protein intake |
| Calories | 200-400 calories per serve | 80-150 calories per serve |
| Macro nutrients | Balance of protein, carbs and fats | Mostly protein, low carbs and fats |
| Micro nutrients | Fortified with vitamins and minerals | Few or no added vitamins or minerals |
| Satiety | More filling | Less filling |
| Best for | Weight loss, convenience, calorie counting | Nutrient goals, active lifestyles |
When should you choose a meal replacement?
Meal replacements come in handy in a few scenarios. If you’re trying to manage or lose weight and need to control calories, they’re very easily trackable. Got a busy schedule? They’re a convenient option for lunch on the go. If you have had a long day, they’ll give you a nutritionally complete dinner without the effort.
They also may be recommended to you by a medical or nutritional professional to help you hit certain targets. The NHS have recently expanded their ‘shake and soup‘ diet which features meal replacements as part of a weight loss programme. Be mindful to not completely eliminate whole foods, though. Meal replacements should be added into your day alongside a balanced, healthy diet.
When should you choose a protein shake?
While they shouldn’t replace entire meals, protein shakes are great ways to meet your nutritional goals. Since protein is the building block for muscle and tissue in your body, these shakes have often been used by people focused on fitness goals. More recently however, protein shakes are being used as part of healthy lifestyle, given the many different benefits of protein.
Basically, if you are looking to increase your daily protein intake for any number of reasons, protein shakes are a simple (and delicious) way to do so!
Can you use both?
So now you know how to differentiate between meal replacements and protein shakes – but do you have to choose one or the other? In short, no.
Both can play a role in a balanced diet, so can be mixed and matched to your individual needs. For example, you could have a protein shake as part of your morning routine to boost your protein intake, and then grab a meal replacement at lunch if you only have a few minutes.
It’s important to note, though, that you should still prioritise whole-food intake as part of a healthy, balanced diet.
What to consider when choosing
To get the best effects from either meal replacements or protein shakes, it’s important to consider a few factors. First, ingredient quality is vital. Many lower quality shakes include added sugar or artificial additives, making them a less-than-ideal addition to your daily diet. Additionally, if you have specific dietary restrictions such as gluten-free or vegan, make sure the one you choose suits them. They’ll normally display this information pretty clearly on the packaging.
Your choice of either meal replacements or protein shakes should be driven by your personal health goals and dietary needs. However, if you’re unsure, you can always chat to your GP or a dietitian for more tailored advice.
