Cutting calories with clinic-style meal replacement programmes usually means paying through the nose for a nutritionist-supervised plan. Shake That Weight takes the same basic idea- a very low-calorie diet built around fortified shakes, soups, bars and meals- and sells it directly to your kitchen instead.
I ordered a mixed box to see what actually turns up, how it mixes, how it tastes, and whether the numbers add up against the calorie counting most of us have tried and abandoned at least once.

What Is Shake That Weight?
Shake That Weight is a UK meal replacement brand selling high-protein shakes, meals and bars designed to replace some or all of your regular food intake. Everything is made and shipped from the UK, and the range spans shakes, soups, bars, meals and snacks rather than a single flavour of powder in a tub.
The pitch is straightforward: swap a meal (or several) for a portion-controlled, nutrient-fortified product and let the calorie deficit do the work. That’s the same mechanism behind hospital-grade very low calorie diets, just packaged for home use rather than delivered under clinical supervision.
How It Actually Works
There’s no app, no coaching call, and no waiting room. You pick a plan intensity, order online, and the products arrive ready to mix or heat.
- Choose your replacement level. Options run from total food replacement across a full day, down to swapping in a single shake or bar for one meal.
- Mix or prepare. Shakes need water or your milk of choice in a shaker; soups need hot water; bars need nothing at all.
- Track your own intake. Because there’s no coaching layer, staying on plan is on you rather than a caseworker checking in weekly.
That third step is worth sitting with before you order. A VLCD clinic gives you check-ins and someone flagging if you’re struggling. Here, the structure works if you’re the sort of person who does fine with a shopping list and a bit of self-discipline, and less well if you know you need someone chasing you.
Taste, Texture and the Bit Nobody Tells You
The chocolate shake mixed easily in a standard shaker bottle, no lumps, no gritty aftertaste sitting at the bottom. That matters more than it sounds. Cheap meal replacement powders often separate or taste chalky by the third sip, and that’s usually the reason people quit a plan in week one rather than any failure of willpower.
The flavor range is wide enough that it doesn’t feel like a punishment by day three, and the reviews I read before ordering backed up what I found in the shaker: that the shakes taste properly drinkable rather than merely tolerable. The soup was a genuine change of pace from another sweet shake at lunchtime, which sounds minor until you’re three days into any restrictive plan and craving anything savory literally.
What’s Actually In It
Every product is high in protein and carries a balanced macronutrient profile alongside 20+ vitamins and minerals, so a single meal replacement is doing more nutritional work than a bowl of cereal ever will. That fortification is the detail that separates a proper meal replacement from a diet shake that’s really just flavoured milk with fewer calories.
Protein matters specifically because it’s the nutrient most associated with satiety, the reason a shake can hold you until your next meal instead of leaving you rummaging through the cupboard an hour later.
There’s also a vegan range sitting alongside the standard products, which matters if a plant-based diet has ruled out most other meal replacement brands you’ve looked at. That’s not a footnote feature. A lot of VLCD-style products are whey-based by default, so a genuine vegan line widens who can actually use this.
Flexibility: Total Replacement or Just Lunch
The plans scale from full total food replacement down to one meal a day, which means you’re not locked into an all-or-nothing structure. Someone easing in can swap breakfast for a shake and leave the rest of their day alone. Someone chasing faster results under their own judgement can replace every meal for a stretch.
That range is closer to how most people actually diet, in stages, with wobbles, rather than the strict on-off switch a clinical VLCD programme tends to enforce. If you’re also looking for ways to use a blender for more than diet shakes, this Nutri Ninja smoothie recipe roundup is worth a look for post-plan maintenance meals.
What It Costs
Prices start from £1.85 per meal, which sits well below what a clinic-based VLCD programme typically charges once you factor in consultation fees and branded product mark-ups. For anyone comparing this to a supervised programme purely on cost, that gap is the whole argument. You’re paying for the product and the fortification, not for a practitioner’s time.
Strengths and Honest Drawbacks
- Flavor variety that survives repetition. Sweet and savoury options mean you’re not stuck rotating the same chocolate shake for weeks.
- Full nutritional fortification. High protein plus 20+ vitamins and minerals per serving means a replaced meal isn’t a nutritional gap, just a calorie-controlled one.
- Genuine vegan coverage. Not every competitor bothers with a proper plant-based line.
- No built-in accountability. There’s no coach or check-in call bundled into an order. If you know you need someone else keeping you honest, that’s a real gap next to a clinic programme.
- Self-directed calorie management. The plan gives you the products, not the calorie maths. You still need to understand your own targets to use total replacement safely, which won’t suit everyone.
- Not a medical intervention. This is a structured calorie-control tool, not a substitute for medical weight management advice, and it shouldn’t be treated as one if you have underlying health conditions.
Who Should Actually Buy This
This fits someone who wants VLCD-style structure without clinic fees, who is reasonably self-motivated, and who wants a straightforward meal replacement decision rather than a full diet overhaul to plan themselves. It also fits vegan dieters who’ve struggled to find a fortified, whey-free replacement range. It’s a weaker fit if you know from past attempts that you need regular external accountability.
The Verdict
Shake That Weight delivers on the basics that actually decide whether a meal replacement plan gets finished: taste that doesn’t wear thin, real nutritional fortification and pricing that undercuts clinic-based alternatives by a wide margin. The flexibility to run it as one meal a day rather than full replacement is what makes it usable for longer than a fortnight.
The trade-off is accountability. You’re managing the plan yourself, with no coach checking in, so it rewards people who already know how to stick to a structure once they’ve bought into it. For that reader, this is a genuinely cost-effective way to run a calorie-controlled plan without booking a clinic appointment first.
