To find the best meal replacement shakes, we assessed a range of the leading brands over a two-week period. We recruited a panel of testers to try them out at home and asked nutritionist, Ruby Chauhan, to analyse the ingredients lists and share her feedback. The Good Housekeeping Institute food team also conducted blind taste tests in our test kitchen. You'll find a full breakdown of how we test below our reviews, along with our expert's advice on supplementing with shakes.
It's important to note that, while meal replacement shakes can help fill the gaps in your diet, you should get the majority of your nutrition from whole food sources, including fruits, vegetables, grains and lean proteins. Supplementing one meal a day is fine, according to Chauhan, but she warns against over-reliance. You shouldn’t use shakes to replace your meals for extended periods. Think of them as a complement to, not a substitute for, a balanced diet.
Protein Works Diet Meal Replacement (1kg, 14 servings)
Pros
- Balanced macronutrient profile to support overall nutrition
- Good consistency and flavour
- Budget-friendly
Cons
- Features sweeteners and stabilisers
- One tester experienced some bloating
Score: 95/100
What is it? This Protein Works powder – which comes in eight tasty flavours – contains oats, soy, whey and milk protein, along with a blend of 23 vitamins and minerals. Simply stir two scoops into 350ml of cold water to prepare. Per 70g serving, it provides 4.7g of dietary fibre and less than 250 calories, making it a good pick for those on a weight loss journey.
Expert verdict: According to Chauhan, this powder has a well-rounded nutritional profile, with a balance of complex carbohydrates and complete protein, delivering all nine essential amino acids. “The vitamin and mineral blend supports overall wellbeing, energy production, bone health and immune function, while the mix of plant and dairy proteins supports muscle repair and satiety,” she says.
“The oats are also beneficial for blood glucose control and lowering cholesterol.” Just note, the powder does include maltodextrin, artificial sweeteners (sucralose) and stabilisers, which can upset sensitive stomachs.
Panel feedback: Testers were impressed with the smooth, lump-free consistency, saying the powder mixed well in water and was easy to swallow. Taste-wise (they tried the white choc bueno flavour), it wasn’t overly sweet and there was no unpleasant aftertaste. Crucially, it kept them satisfied for a few hours until their next meal.

What is it? Packed with 33 natural ingredients, including organic oats, a plant-based protein blend, nuts, seeds, adaptogens and antioxidants, this meal replacement avoids the artificial ingredients often found in similar products. Vegan, gluten-free and dairy-free, it’s ideal for those with dietary needs, plus it contains a whopping 9g of fibre to promote gut health and keep you feel fuller for longer.
The expert verdict: “This has an impressively clean and thoughtfully curated ingredients list, with a wide range of organic, whole food ingredients,” says Chauhan. She adds that the inclusion of plant proteins, superfoods and adaptogens like reishi and maca provide natural energy, aid recovery and support overall wellbeing. The high fibre content could cause GI discomfort for some, though.
Panel feedback: Panellists loved the recyclable packing and all-natural ingredients list. They weren’t fans of the shake when mixed with water alone – it was lumpy, slightly bitter and hard to drink – but thoroughly enjoyed the taste (rich with cinnamon and cacao) and texture when blended with a banana and some milk. They also liked the handy sachets for ease of use – there's no need to faff around with scoops and scales when you’re in a rush.

Each bottle provides a carefully curated mix of protein, fats, carbs and fibre along with 26 essential vitamins and minerals.

Expert verdict: Huel includes high-quality proteins from pea and brown rice (which provide a complete amino acid profile) plus healthy fats from flaxseed and medium-chain triglycerides. It has a decent amount of fibre along with functional ingredients like green tea extract, probiotics and plant-derived vitamin D3. “These add extra health benefits, supporting metabolism, gut health and immunity,” Chauhan says.

Panel feedback: According to testers, this ready-to-drink option is a game-changer on busy days. They scored it highly for ease of use and said it was both filling and satisfying. No one experienced any unwanted side effects like bloating, either. Some found the taste (we tried chocolate) a little too sweet and cloying, but on the whole, testers said it was pleasant to drink and they liked the thick consistency.

Expert verdict: "The powder features a well-rounded blend of macronutrients and functional ingredients including complete plant-based proteins, healthy fats and moderately low-GI carbohydrates,” says Chauhan. Along with the full spectrum of vitamins and minerals (including D3 and K2), the addition of probiotics, green tea extract, lutein and kombucha powder dish up extra digestive and antioxidant benefits. It does contain flavourings and sweeteners, but you can opt for the unflavoured, unsweetened version if you want to steer clear.
Panel feedback: Everyone said this meal replacement was extremely filling, preventing any mid-afternoon hunger pangs. One tester told us it aided their weight loss, and another said it helped them to feel energised and less tired.

How we test meal replacement shakes
To find the best meal replacement shakes, we sent a variety of options from big brands to a panel of testers to try them at home over two weeks. Following the testing period, they provided detailed feedback on their experiences via an in-depth survey. They assessed flavour, consistency and ease of use, as well as telling us how it impacted their performance, along with any other specific likes and dislikes.
Back in the Good Housekeeping Institute test kitchen, our expert food team tasted tested them all. Packaging was blinded to avoid brand bias and they judged them on flavour, texture and aroma.
We also asked Chauhan to assess each product based on nutritional make-up and quality of ingredients.

What’s the difference between a protein shake and a meal replacement shake?
“Protein shakes are designed to supplement your diet with additional protein, and are often used after a workout to support muscle growth and repair,” explains Chauhan. “They usually contain little to no fat, carbohydrates and micronutrients.
“Meal replacement shakes, on the other hand, contain a comprehensive array of macro- and micronutrients, making them suitable as a full meal replacement.”
Check out our round-ups of the best protein powders and best protein bars if you're after a post-workout boost.
How to choose a meal replacement shake
If you do want to invest in some meal replacement shakes to help you hit your nutrition goals when life gets busy, there are a few key things to consider.
Firstly, look for a balanced blend of nutrients. “Aim for at least 15-20g of complete protein (like whey, pea or soy), healthy fats like flaxseed and complex carbohydrates such as oats,” says Chauhan. “A good shake should provide at least three to five grams of dietary fibre and include a broad range of essential vitamins and minerals.”
“Ideally, look for a product that’s low in added sugars and contains minimal additives and emulsifiers, which could cause gastrointestinal problems,” she adds.
Ultimately, it’s about finding what works for you and your body. If you have a sensitive stomach, opt for a shake made from more natural ingredients, and if you’re trying to build some muscle in the gym, a high-protein option is your best bet.
What are the downsides of meal replacement shakes?
While meal replacement shakes can be extremely convenient, there are some drawbacks.
“Depending on shakes in place of whole foods can limit dietary variety and increase the risk of micronutrient gaps,” notes Chauhan. Over time, this could potentially lead to deficiencies in certain vitamins and minerals, as well as fibre.
Gut health is another potential issue. Many meal replacement shakes contain artificial sweeteners, flavourings and preservatives, which can cause bloating and digestive discomfort – especially for those with sensitive stomachs. Most also lack probiotics and digestive enzymes, which are beneficial for a healthy gut.
Chauhan also points out that if you rely on meal replacement shakes for all three meals a day, you may end up consuming too few calories. “This could lead to fatigue, low mood and reduced capacity for physical activity,” she says.
Who should avoid meal replacement shakes?
While meal replacement shakes are generally safe for most people, they might not be suitable for everyone, including those with certain health conditions, dietary restrictions or food allergies.
Those with diabetes, for instance, may need to limit sugar intake, while those with kidney or heart disease may find the protein or salt contents unsuitable. As with any supplement, it’s advisable to check with a healthcare provider – especially if you have a chronic health condition, you’re pregnant or breastfeeding – before incorporating a meal replacement shake into your routine.
“They’re also not recommended for those with eating disorders,” warns Chauhan. “Their restrictive nature and association with weight control can be triggering and may negatively impact recovery.”
The verdict: are meal replacement shakes worth it?
Meal replacement shakes can help you stay nourished and energised when nutrient-dense meals comprised of whole foods aren’t an option.
Our joint winner, the Protein Works Diet Meal Replacement is worth considering if you’re after a whey-based option. It has a good balance of macronutrients, the consistency is smooth, and testers confirmed the shake is satisfying.
If you're looking for a plant-based blend that’s free from artificial ingredients, our other joint winner, 33 Fuel's Elite Meal Replacement Shake, is your best bet. It’s packed with natural ingredients; it comes in single serve sachets for convenience, and it contains an impressive 9g of fibre.
