Weight Loss Shake
Your weight loss shake. This wholesome meal replacement provides you with all the important nutrients you need - including high-quality protein, fibre, vitamins and minerals. Sugar-free, vegan and quick to prepare, it helps you lose weight effectively with just 203 kcal per portion and helps you achieve your weight goal in the long term.
A weight loss shake — also known as a diet shake — is a calorie-reduced meal replacement that provides less energy than a regular meal while still covering all essential nutrients: protein, fibre, healthy fats, vitamins and minerals. The goal: a controlled calorie deficit without compromising your nutritional intake.
Protein content alone doesn't make a good weight loss shake. A straight protein shake lacks fibre for keeping you full, fats for the absorption of fat-soluble vitamins (A, D, E, K) and micronutrients like iron, zinc or magnesium. A weight loss shake that works as a standalone meal brings all of that to the table.
In the EU, weight management products are subject to strict regulations — the so-called formula diet defines ranges for calorie content (a maximum of 250 kcal per serving), protein proportion (25–50% of energy) and micronutrient density. Products that meet these criteria ensure adequate nutritional intake even on a reduced calorie diet.
Not every shake that calls itself a "weight loss shake" actually meets these requirements.

203 kcal, 17 g of protein, 11 g of fibre — the Shape Shake delivers less than half the calories of an average meal, but a complete micronutrient profile with 26 vitamins and minerals.

11 g of fibre per serving — more than most diet shakes offer. The inulin comes from chicory root and acts as a prebiotic: it feeds the beneficial bacteria in your gut microbiome. The added probiotic Bacillus Coagulans complements this effect. Together, they ensure that 203 kcal keeps you full for up to five hours.
Pea protein and brown rice protein complement each other to achieve a high biological value with all essential amino acids. 17 g might sound less than the 20–27 g in other diet shakes — but context matters: at just 203 kcal, 33% of the total energy comes from protein. That puts it in the upper third of the EU requirements for formula diets.
Flavours: Cocoa (bestseller), Vanilla and Strawberry. Price: €29.90 for 25 servings — that's €1.20 per meal.
€1.20 per serving with the Saturo Shape Shake — typical diet shakes sit between €1.50 and €2.99. But price is only one factor. Sugar, fibre and protein source set weight loss shakes apart far more than the packaging might suggest.
Three things stand out. First: 11 g of fibre — two to three times as much as most competitors. Second: zero grams of added sugar. Some diet shakes pack up to 30 g of sugar per serving (read the ingredients list — honey, maltodextrin and glucose syrup all count). Third, the price: €1.20 is the lowest in the comparison.
On protein, the Shape Shake comes in below some competitors. If you need 30+ g of protein per meal — for heavy weight training, for example — the Saturo ready-to-drink meal is an alternative with 36 g of protein at 400 kcal. It's not designed as a calorie-reduced weight loss shake, though, but as a complete meal.
Yes — as long as you're in a calorie deficit. Your body loses weight when it burns more energy than it takes in. A Shape Shake at 203 kcal replacing a meal of 500–700 kcal saves you 300–500 kcal per meal.
Putting it into practice has two pitfalls.
The first: your basal metabolic rate. If you cut calories too drastically, your body thinks it's starving — your metabolism slows down, and once the diet's over, the yo-yo effect kicks in. You put weight back on faster than before. A moderate deficit of 300–500 kcal a day is enough. That's one to two replaced meals, not three.
The second: muscle mass. In a deficit, your body dials down muscle protein synthesis — it doesn't just burn fat, it breaks down muscle tissue too. Protein works against this: it contributes to the maintenance of muscle mass. The 17 g in the Shape Shake does its bit, and you cover the rest through your regular meal.
How much weight loss is realistic in two weeks? At a 500 kcal deficit per day: roughly one kilogram of body fat. Anything beyond that is usually water loss. If you want to lose belly fat, you need weeks — no shake in the world melts fat from a specific area (spot reduction is a myth).
7:15 in the morning. The train leaves in three minutes. Breakfast isn't happening — or you down a Shape Shake in 30 seconds. 203 kcal, 17 g of protein, full until lunch.
Replace one to a maximum of two meals a day. Your remaining meal should be made up of fresh, balanced food: vegetables, whole grains, lean protein sources. Your calorie calculator shows you what your daily intake should be and how much of a deficit makes sense. A weight loss meal plan helps you structure your shake days and your regular meals.
How long you use it depends on your goal. Use the Shape Shake until you've hit your target weight — then phase it out over two to four weeks. Gradually swap out the shake meals for home-cooked food to avoid the yo-yo effect. Don't stop all at once. That's the point where most diets fall apart.
Not every diet shake suits every way of eating. Many weight loss shakes are based on whey protein, casein or soya protein — and contain lactose, added sugar, or both. The Saturo Shape Shake uses none of them.
Protein from pea and brown rice. Completely soya-free. No added sugar, just 1 g of naturally occurring sugar per serving. No lactose. That makes it the option for anyone looking for a weight loss shake without sugar, without soya and without animal-derived ingredients.
One thing to note: the Shape Shake contains oats, so it's not gluten-free. If you have coeliac disease or need a strict gluten-free diet, the Saturo Ready-to-Drink is a gluten-free alternative — though at 400 kcal rather than 203, so it's not designed as a calorie-reduced weight loss shake but as a complete ready-to-drink meal.
A good weight loss shake delivers a complete nutritional profile at low calories: enough protein, fibre, vitamins and minerals — with no added sugar. The Saturo Shape Shake offers 203 kcal, 17 g of protein, 11 g of fibre and 26 vitamins for €1.20 per serving.
No shake targets belly fat specifically. Spot reduction — losing fat in a specific area through certain foods — isn't physiologically possible. Any weight loss shake that creates a calorie deficit leads to fat loss across the entire body. Where your body loses fat first comes down to genetics.
Yes — as long as you're in a calorie deficit. Replacing a meal of 500–700 kcal with a shake at 203 kcal saves you 300–500 kcal. At a 500 kcal deficit per day, you'll lose roughly 0.5 kg of fat a week.
Once or twice a day as a meal replacement. Your third meal should be made up of fresh food — vegetables, whole grains, lean protein — to ensure nutritional variety and build healthy eating habits for the long term.
Until you've reached your target weight. After that, gradually replace the shake meals with regular food over two to four weeks. Stopping all at once increases the risk of the yo-yo effect.
€29.90 for 25 servings, which works out at €1.20 per meal. Typical diet shakes cost between €1.50 and €2.99 per serving — making the Shape Shake one of the cheapest weight loss shakes on the market.
Yes. The Shape Shake is 100% vegan, lactose-free and soya-free. It contains 0 g of added sugar — just 1 g of naturally occurring sugar per serving. The protein comes from pea and brown rice.
