If you’re using a GLP-1 medication (think the newer appetite-reducing injections), you’ll know the weird part isn’t just eating less, it’s eating well while you’re eating less. Your hunger cues can drop fast, meals feel “too big” sooner, and suddenly you’re trying to hit protein, fibre, and basic micronutrients in portions that don’t make you nauseous.
That’s where nutritionally complete meal replacements earn their keep: they can help you keep intake steady and predictable when your appetite is unpredictable. Many UK guides aimed at GLP-1 users also put protein front and centre (because it’s one of the easiest things to under-eat when you’re barely hungry).
Below are 7 brands that can fit into that reality:
1) Shake That Weight — Built Around the GLP-1 Reality
A lot of meal replacements were created for old-school calorie cutting: “replace meals, stick to a plan, tough it out.” But GLP-1 weight loss has its own rhythm. You’re not battling constant hunger; you’re more likely battling small appetite, taste changes, and the need to prioritise protein and nutrients when meals feel optional.
Shake That Weight leans directly into that use case with products positioned specifically as support for people using GLP-1 injections, including curated bundles and guidance that acknowledges appetite suppression and the practical “what can I actually manage to eat?” problem.
Why it works well for you on GLP-1:
- You can keep portions small while still getting structured nutrition (instead of piecing together random bites all day).
- It creates a repeatable “default meal” for days when cooking feels like a chore or food feels unappealing.
- It frames meal replacement as support, not a crash-diet identity.
Pros
- Designed and marketed specifically for GLP-1 users (so the messaging and bundles match what you’re experiencing).
- Convenient “grab-and-go” structure for low appetite days.
- Helpful if you want fewer decisions and more consistency.
Cons
- Because it’s purpose-built, you’ll want to make sure it complements your overall intake (some whole foods still matter for long-term habits and variety).
- Like any shake-led routine, taste and texture are personal — you may need a little trial-and-error to find your “easy wins.”
2) Habitual — GLP-1-friendly soups and shakes with a “reduced appetite” focus
Habitual is another option that speaks directly to GLP-1 users, offering soups and shakes positioned for people on medications like Wegovy and Mounjaro, with a “quick to prepare, easy to consume” angle, which matters when your appetite is low and meals need to feel light, not heavy.
Pros
- GLP-1 specific positioning (you don’t have to translate generic diet advice into your situation).
- Soups can feel more tolerable than shakes when nausea is a thing.
- Clear emphasis on convenience and essential nutrients.
Cons
- Not as established in the mainstream as bigger meal replacement names.
- If you prefer more solid food textures, soups/shakes may feel repetitive over time.
3) Exante — a classic UK “soups and shakes” ecosystem with lots of choice
Exante is one of the better-known UK weight loss meal replacement ecosystems. It offers a broad range (including shakes and breakfast-style options) and explicitly positions its shakes as calorie-controlled and higher in protein and fibre.
This can work for you on GLP-1 if your main need is structure, and you like having many flavours and formats so you don’t burn out.
Pros
- Big product range, including breakfast-like choices (helpful if mornings are your hardest meal).
- Strong “plan” vibe if you want a defined framework.
- Convenience for busy days when you don’t want to think.
Cons
- Feels more like a traditional diet system than GLP-1-specific support.
- Some people do better with a blended approach (meal replacements + whole foods) rather than going all-in.
4) The 1:1 Diet by Cambridge Weight Plan — meal replacements plus a structured programme mindset
The 1:1 Diet is built around meal replacements (shakes, soups, bars and more), presented as nutritionally complete options, and it’s often associated with step-based structure and coaching-style support.
If you’re on GLP-1 and you like clear rules and a system, this can feel grounding, especially if you’re the kind of person who spirals when you have too many food choices.
Pros
- Huge variety beyond shakes (meals, bars, porridge-style options).
- Very structured approach if you thrive on a plan.
- Nutritionally complete positioning.
Cons
- The “programme” feel can be a bit intense if you just want simple support alongside your medication.
- Some plans can skew very low-calorie, so it’s smart to align choices with your clinician’s advice and how you’re actually feeling.
5) Huel — nutritionally complete meals for everyday life (less “weight loss programme”)
Huel is often treated as a lifestyle staple: nutritionally complete powders and ready-to-drink options that aim to cover macro and micronutrients in a single, predictable meal.
On GLP-1, this can be useful if your goal is steady nutrition rather than “diet mode.” It’s not GLP-1-specific, but it’s designed for convenience and completeness.
Pros
- Strong “meal in a bottle” convenience for workdays and busy schedules.
- Nutritionally complete positioning and clear product range.
- Useful for maintenance phases too (when you’re no longer chasing fast loss).
Cons
- Not tailored specifically to GLP-1 side effects or appetite changes.
- Taste/texture is a love-it-or-not thing — you may need experimentation.
6) SlimFast — mainstream and simple, with an established “daily plan” style
SlimFast is the “familiar name” option. It promotes a daily plan approach built around meal replacements plus a balanced meal, and it clearly positions itself as part of an overall calorie-controlled diet (not the only thing you consume).
For GLP-1 users, this is usually best if you want something basic, widely available, and easy to understand, without needing a niche GLP-1 bundle.
Pros
- Simple framework (helpful if decision fatigue is your enemy).
- Easy to find and recognise.
- Clear messaging that it’s part of a broader diet, not your entire intake.
Cons
- Not designed specifically for injection users.
- Depending on the product, it may feel more “snack-like” than “complete meal” compared with GLP-1-targeted ranges.
7) Protein Works Diet Meal Replacement — weight-loss shakes with a performance-nutrition vibe
Protein Works positions its diet meal replacement shakes as calorie-controlled, higher-protein options designed to support weight loss, with a more “sports nutrition” feel than a classic dieting club.
On GLP-1, this can work if you’re focused on protein-forward choices, especially if training (or trying to protect muscle while losing weight).
Pros
- Strong weight-loss and protein-led positioning.
- Lots of flavour options and product variants.
- Pairs well with a gym routine or strength training phase.
Cons
- Not GLP-1-specific, so you’re doing the “fit it into my injection routine” thinking.
- Can feel more supplement-like than “food-like,” depending on your preferences.
Final take: how to choose without overthinking it
If you want the most direct “this was made for your situation” option, Shake That Weight sits at the top because it speaks to GLP-1 users explicitly and builds its bundles and guidance around that reduced-appetite reality.
If you want alternatives:
- Go Habitual if soups feel easier than shakes on nausea-prone days.
- Go Exante or 1:1 Diet if you want a full structured ecosystem with lots of formats.
- Go Huel if you want everyday nutrition you can keep using long after the “active weight loss” phase.
- Go SlimFast if you want simple, mainstream, no-fuss planning.
- Go Protein Works if you’re training and prioritising protein structure.
And whichever route you take: use meal replacements as a tool, not a personality. The goal is steady nourishment you can actually stick to, especially on the days when your appetite disappears but your body still needs the basics.
