Nupo Diet Reviews — Trusted Results for Safe Weight Loss
Nupo isn’t a trend — it’s a clinically backed approach to meal replacement and weight management.
For over 40 years, our Danish nutrition experts have developed Total Diet Replacements (TDR) and meal replacements (MRP) that combine low calories with complete nutrition.
Each product is designed to:
- Replace 1–2 meals per day as part of a calorie-controlled diet.
- Provide all essential vitamins, minerals, protein, and fiber.
- Support weight loss without hunger or nutritional compromise.
- Fit effortlessly into busy lifestyles — anytime, anywhere.
FAQ
The first week of the Nupo Diet – what to expect?
Can I mix Nupo Diet and Nupo One Meal?
We do not recommend combining the two product lines, due to differences in nutritional values.
Nupo Diet is a full meal replacement whereas One Meal is a single meal replacement, and nutritional values are there for optimized to replace one or two main meals a day, and contains all the nutrition, i.e. Proteins, fibers, vitamins, and minerals.
Even though the content of calories is approximately the same, if you exchange two sachets of Nupo Diet, with a One Meal product, the nutritional values are not the same, and when dieting, covering the basic needs for nutrition is highly important, to achieve the desired results.
What is ketosis?
“The new black” amongst diets are the so-called keto-diets. A common denominator for these diets is that you consume very few carbohydrates and a larger amount of fat when compared to the official recommendations. However, what is ketosis?
A simple explanation is that ketosis is a state, in which your body gets its energy from its fat stores instead of the glycogen stores in your muscles. Normally, your body’s fuel comes from carbohydrates, which are stored in the muscles as glycogen. When you decrease/limit your carbohydrate intake, you will force your body to find an alternative energy source – in this case: stored fat. When the body begins to use the stored fat as fuel, the body will transform the fat into ketones, which it uses as fuel instead of glycogen.
If you read about keto diets, where you eat regular food with a low amount of carbohydrates, there are many different theories about how many carbohydrates, you are allowed to consume to enter the state of ketosis and maintain that state. With Nupo’s VLCD (Very Low-Calorie Diet), you get a lower amount of carbohydrates, than a normal diet – that follows the official recommendations – and therefore you will enter the state of ketosis, by using Nupo’s VLCD Diet Shakes. You will maintain the state of ketosis, by sticking to the Nupo Diet – you can use Nupo’s Diet Shakes for up to three weeks.
If you start complementing the Nupo Diet with other foods, you might not achieve the same success – to give yourself a better chance for success, you must stay strictly to the Nupo Diet. This is because, if you add other foods to your diet, you might lose the state of ketosis, even though you are still in a calorie- and carbohydrate deficit. It can be very difficult to be on a keto diet with regular foods, as it is strict regarding the food you may, and may not, eat.
With Nupo’s VLCD Diet Shakes, you get all the necessary nutrients and vitamins, and a calorie- and carbohydrate deficit, which makes it easier to maintain the state of ketosis. A positive side effect of ketosis is that it lowers your appetite, which is smart if you want to lose weight, and this is even though you are consuming fewer calories and a regular diet – it takes a couple of days on Nupo, to get to this state.
Nupo has presented three new products to their VLCD-line, which are an Oatmeal – Apple Cinnamon, and two soups: Diet Soup – Tomato and Diet Soup – Vegetable. This means that Nupo has three soups, which is great as a lunch or dinner alternative, and the Oatmeal is perfect as breakfast. Furthermore, Nupo’s classic Diet Shakes comes in five different variations: Mango Vanilla, Blueberry Raspberry, Strawberry, Chocolate Flavour, and Café Latte. It is important that you stick to the diet, give yourself the best preconditions for a successful weight loss, and do not complement the diet with regular foods that might affect the state of ketosis.
Can Nupo Diet-shakes and soups be mixed with hot water?
Yes, you can mix up your Nupo Diet shakes with warm water, but we advise that you enjoy them chilled.
We experience that the majority prefer that the shakes are refrigerated before they are consumed.
Our Nupo Diet Soups and Oat Meal should be mixed with cold water and then heated in the microwave or in a pot.

I get a severe amount of air in the stomach when I eat Nupo.
The Nupo Diet and the related sachets that must be consumed six times daily contain a lot of fibers and some might experience more air in their stomach. This is perfectly normal and is only a question of your body adapting.

Can I experience headaches when I eat Nupo?
If you make sure to consume all your sachets from the Nupo Diet and drink enough liquid (2-3 liters of water every day is recommended), then it should not be something to worry about. You might experience headaches if you are accustomed to consuming big amounts of sugar, and then stop doing that while on a Nupo Diet. If a headache might occur, it should be gone within a relatively short time when the body gets used to the Nupo Diet.

Can I settle for 4-5 sachets of Nupo and supplement with a healthy supper?
We advise that you always eat 6 Nupo-meals every day – this still applies even if you supplement with real food.
This is important to make sure for us that you get all the vitamins, minerals, and nutrients that you need. Even though that one might think that the food you supplement with is healthy and nutritious, it is not certain that it contains everything that you and your body need. If you want to eat dinner nonetheless, we suggest that you take a sachet of Nupo Diet about half an hour before the meal. By doing this, you will make sure that you will not be as hungry and therefore less tempted to eat more of the real food.

Can I freeze my Nupo Diet-shakes?
Yes, you can freeze down your Nupo Diet-shake (short term!), for 1-2 days. Some choose to freeze down their Nupo Diet-shake for 15-30 minutes before they drink it, as to have an ice-cold and delicious shake that will have a thicker and slush ice-like consistency.
If you freeze down your shake the night before, you can bring it in the morning, and later in the day, you will have a chilled shake. You must be aware, that the thawing period can vary since it depends on the immediate temperature in the environment you are in. Some even enjoy a frozen Nupo Diet-shake as a delicious Nupo ice cream, when they are craving something sweet – in this case, you have ice cream with low-calorie content.

Can I prepare my Nupo Diet-shakes in advance?
Yes, you can prepare your Nupo Diet shakes a day in advance so that they are ready for use immediately. They must be stored in a chilled environment just like a milk drink – we experience that the majority prefer that the shakes are refrigerated before they are consumed. Before enjoying your shake, you can to your own advantage shake it up. Bon appetite.

Can I use Nupo if I have type 1 diabetes?
Yes, it is safe to make use of Nupo Diet Shakes which are VLCD (Very Low-Calorie Diet), if you have type 1 diabetes. It is important to note that you should consult your doctor (diabetes specialist) before you start a diet program. The reason being, that the insulin dose should be reduced first or there could be a risk of hypoglycemia (low blood sugar). For patients in treatment that includes meal-based insulin, it is a good idea to consult a dietitian, to make the insulin dose match with the carbohydrate amount in each meal VLCD every day.
What does VLCD stand for?
VLCD stands for Very Low-Calorie Diet.
The Nupo Diet consists of 6 daily Nupo Diet Shakes, -Soups, or -Oatmeal and is a VLCD diet. The guidelines for a VLCD diet are very strict and make sure, that you as a consumer get 100% of the vitamins, minerals, and nutrients that you and your body need daily while keeping the number of calories low – approx. 700 calories per day.
According to the guidelines for a VLCD diet, as a complete diet replacement, it may contain between 450-800 kcal. Studies have shown that you do not lose weight quicker, by consuming less than 800 kcal per day. The Nupo Diet will provide you with approx. 700 calories that are split over 6 meals. Splitting your shakes over 6 meals will help you keep your blood sugar stable and your digestion going.
At Nupo we offer the Nupo Diet which is a VLCD diet that comes in 9 different flavors – meaning there is something for everyone.

How do I stop with the Nupo Diet when the desired weight loss is achieved?
It is an advantage for your body if you continue with the good meal pattern with 6 meals a day, that you have worked towards while following the Nupo Diet. We advise that you eat 3 main meals (morning, noon, and evening), with a focus on eating by the “plate model”, and prioritize lots of coarse vegetables and lean meat. In addition, it is recommended to have 2-3 snacks during the day, to keep your combustion active, as well as keeping your blood sugar stable. A low-calorie snack could be an egg, a handful of almonds, or a couple of carrots. You could try some of our other products such as our One Meal-products or our Protein Bites.
The One Meal series consists of an assortment of meal replacements that can you can use to replace 1-2 of your daily main meals. You can read more about the One Meal series here.

*The “plate model” is a term used to describe the recommended distribution of carbs, proteins, and fat on your dinner plate.
Will it stop my fat metabolism if I only eat Nupo?
No, consuming only Nupo products will not stop your metabolism. This is partly due to the content of different nutrients and fibers as well as the fact that you on a Nupo Diet should eat six sachets (of 32 grams) of our Nupo Diet products, every day. The numerous smaller meals throughout the day are better at maintaining your fat metabolism, rather than fewer big meals.
