Start with the cost of a single serving
A meal replacement shake is something you would buy over and over, so the figure that decides your month is the price of one serving rather than the number in the banner. Across the shakes in this comparison, entry prices run €3.03 to €91.41 while the cost per serving runs €0.93 to €11.39. Read those two together and you can see how far apart the cheapest and the most expensive options sit before you taste anything.
The brands differ more than that spread suggests. Body Attack lists a whey protein from €29.99 and puts it at €1 per serving. Body & Fit lists its whey from €34.99, which works out at €1.52 per serving. Protein Works lists £8.99 with £0.15 per serving, in a different currency from the two European brands, so check the currency attached to each amount before you set the numbers side by side.
Once you have the two prices for each brand, a simple habit saves money later: divide the price per serving by the protein per serving. That gives you the cost of a gram of protein in a single cup, which is the only comparison that stays fair when a shake contains more or less of everything else. The Body Attack review and the Body & Fit review both set out how their entry shakes are built, so they are useful next to this arithmetic.
Protein per serving tells you how filling a shake will be
A meal replacement stands in for a meal, so the protein figure matters more here than it would for a post-workout shake. Across the range, protein per serving runs 18 to 44 g, which is a wide spread and the clearest single separator between the options.
Among the brands here, Body & Fit comes out at 26 g per serving, the highest of the three with a listed protein figure. Body Attack sits at 24 g and Protein Works at 20 g. In practice, a higher number usually means a shake that stays with you longer between meals, while a lower number may need a snack to carry you to the next meal.
Pair the protein figure with the ingredient list and the diet labels before you commit. A high protein number on its own says nothing about sugar, fibre or whether the sweetener suits you, so treat it as one column in a table rather than a verdict.
Confirm the brand actually sells a meal replacement
Not every protein brand in this guide makes the product you are shopping for. The ranges listed for Body Attack and Body & Fit both include a meal replacement line alongside powders, creatine, bars and other products, which you can see in whey protein, plant protein and creatine and whey protein, plant protein and creatine. That range breadth is useful, because you can buy your shake and your training nutrition from one basket and pay one delivery.
Protein Works sits differently. The range set out in multivitamins, vitamins minerals and omega 3 is built around vitamins, minerals and daily supplements, so if your goal is replacing a meal you will need to look elsewhere or check the current range before ordering. The meal replacement shake rankings are the quickest way to see which brands on the site carry a genuine meal replacement product.
Certification, testing and diet fit
Quality signals are where brands look most alike on the shelf and differ most on the label. Body Attack lists organic and vegan certifications and states that its products are third-party tested. Protein Works, by contrast, is not third-party tested. That distinction alone is enough to push one brand up your list and the other down, whatever the price says.
Nashua Nutrition holds the gmp certification, and its diet labels cover vegan, gluten free and keto. For a shake that has to stand in for food, that kind of manufacturing standard is worth reading closely, and the Nashua Nutrition review sets out what it covers.
Diet labels are the quickest filter. Body Attack lists vegan, vegetarian and gluten free and Protein Works lists vegan, vegetarian and gluten free, so if you avoid an ingredient, check the label for your exact requirement rather than assuming a brand is suitable from its range name.
Delivery reach and the window to change your mind
A shake you like but cannot ship to your address is not a good buy. The markets listed for Body Attack cover DE, AT and BE, and Body & Fit lists GB, DE and AT. Protein Works serves GB, IE and FR, a much shorter list, so anyone outside those areas should confirm delivery before filling a basket.
The return window is the safety net and the lengths differ. Protein Works offers 180 days, while Body & Fit offers 30 days. On a product you may eat daily for weeks, that gap is the difference between a long trial and a single taste test, and it belongs in your decision alongside price.
Company details are worth a glance for anyone who wants a named counterparty. Body Attack is run by Body Attack Sports Nutrition GmbH & Co. KG and is headquartered in DE. Protein Works trades as Class Delta Limited from GB, and Body & Fit as Body & Fit Sportsnutrition B.V. from NL. Background dates also help you judge how settled each brand is: Body & Fit has traded since 1995, Protein Works since 2013 and Nashua Nutrition since 2001.
Support, subscriptions and how you will actually order
If you are replacing meals, you will order more than once, so the subscription terms matter as much as the shelf price. Protein Works applies a 15% discount on subscription orders. Work out your real cost per serving with that applied before you compare it against a one-off purchase from a brand with no subscription option.
Flavour count predicts whether you will get bored. Body Attack lists 18 flavours, Protein Works 8 flavours and Body & Fit 4 flavours. A wider list helps if you plan to drink the same shake most days for months.
Help matters when a delivery is late or a flavour is not for you. Body Attack offers email, phone and help centre, Protein Works email, chat and phone and Body & Fit email, chat and phone, the last including a community channel. More ways to reach a company usually mean faster answers on the practical problems that follow an order.
