Can I exercise while I am on the Nupo diet?

It is a good idea to combine Nupo and exercise for greater weight loss. However, some people find that their endurance may be slightly lower due to the low daily energy intake.

I have been prescribed medication by my doctor – can I continue my Nupo diet?

It depends greatly on the medication you are taking. Therefore, it is important that you speak with your doctor about whether you can take Nupo in conjunction with your medication.

Can I breastfeed while I'm on Nupo?

We do not generally recommend that nursing women take Nupo, but it is a good idea to talk with your doctor about this.

I have become ill and have a fever. Can I continue my Nupo diet?

If you are ill and have a fever it is a good idea to consult your doctor about using Nupo. Your doctor can assess whether it is advisable to continue the diet while you have a need for energy to get well.

Will I gain all of the weight again when I stop the Nupo diet?

If you return to the same diet and meal pattern as before you went on the Nupo diet, then yes, your weight will probably creep back again! It’s a matter of changing your eating habits after a Nupo diet to make sure that the weight stays off. 

An idea is to incorporate our One Meal products into your usual diet after completing your weight loss. You can use our One Meal-products to replace 1-2 of your main meals every day.

Will my metabolism slow down if I only eat Nupo?

No, it will not. This is partially due to the nutrients and fibres in the Nupo Diet products, and partiallly due to the fact that you eat 6 Nupo portions per day. Eating many small meals during the day keeps your metabolism high by constantly supplying your body with food that it can break down.

How do you stop the Nupo diet when you have lost the weight you want?

Many people have benefited from using a Nupo One Meal product to replace 1 or 2 of their daily main meals when they start eating regular food again. Each One Meal product only contains approx. 200 kcal, which will help you keep your daily calorie intake low.

It is beneficial for your body to continue the good meal pattern you have established with 6 Nupo meals per day – now with regular food. We recommend that you eat 3 main meals and approx. 2 low calorie snack per day. This will enable you to maintain stable blood sugar levels and high metabolism, which makes it easier to avoid binge-eating.

What does VLCD mean?

VLCD stands for Very Low Calorie Diet. The Nupo diet, consisting of 6 Nupo meals per day, is a VLCD. Legislation in the field of VLCDs is very strict and ensures that users of these diets are guaranteed to get the vitamins, minerals and nutrients they need in a daily diet – with a minimum of calories. By law, a VLCD may contain between 450 and 800 calories per day. Studies have shown that you cannot lose weight faster by consuming fewer than 800 calories daily. The Nupo Diet gives you approx. 700 calories per day spread over 6 meals. You get the vitamins, minerals and nutrients that your body needs for effective and safe weight loss.

I have a measuring cup for my Nupo powder – how many do I need for a Nupo meal?

1 measuring cup is equivalent to 1 Nupo Diet portion


Can you mix Nupo Diet Shakes and Soups with hot water?

You can mix your shakes with hot water, but we recommend that you use cold water. The soups should be mixed with cold water and heated in a microwave or saucepan.

Can I make my Nupo Diet shakes in advance?

Yes, you can make all of your Diet shakes one day in advance. They just need to be refrigerated like a dairy beverage. Before enjoying your shake, you may want to shake it up one more time.


Can I freeze my Nupo Diet shakes?

Yes, you can freeze your Diet shake briefly for 1-2 days. Some people freeze their Diet Shake for 15-30 minutes before drinking, making it ice cold and delicious – and a little more thick and slushy! If you freeze your shake the night before, you can take it with you in the morning and enjoy an ice-cold shake later in the day. Just note that the thawing time may vary depending on the temperature where you are. Some people also enjoy a frozen Nupo Diet as a delicious Nupo Ice Cream when the sweet tooth calls – ice cream with a minimum of calories.

Can I freeze a Nupo One Meal Shake?

Yes you can – then you will have a delicious ice cream that also contains all of the good nutrients!


Do Nupo products lose vitamins or minerals if you prepare them the night before?

Preparing your shake the night before makes no difference, as long as you keep it refrigerated. Vitamins, minerals and nutrients are not harmed, so you can prepare the shake the night before worry-free.

Nupo and meals

Can I make do with 4-5 Nupo packets and supplement them with a healthy dinner?

You must always eat 6 Nupo meals a day - even if you supplement your diet with other food!

This is very important to ensure that your body gets all the vitamins, minerals and nutrients that it needs. When you supplement your Nupo Diet with regular food, it is not certain that you will get everything your body needs. If you would like to eat dinner, it is a very good idea to eat a Nupo meal 30 minutes before to temper your hunger and help you resist the temptation to eat too much!

Can I replace just one meal with Nupo Diet?

If you do not want to replace your entire diet and eat 6 Nupo meals daily, you can replace one main meal with 2 Nupo Diet products, which will provide more than 30% of the vitamins and minerals you need in your daily diet.


Can I replace Nupo powder with a Nupo bar or ready-to-drink product?

No. Our One Meal bars and shakes bars are meal replacements and should not be used to replace your Diet shakes.

Do I need to take vitamins when I am only eating Nupo?

No, it is not necessary unless you need to take a larger dose of a specific vitamin. 

You can also combine Nupo with other food in different ways. Of course, this will add extra calories, but if you feel too hungry when eating Nupo alone, it can help to eat a little bit of healthy food on the side. 

Other questions

Do people get headaches when they eat Nupo?

If you make sure to eat all of your Nupo portions and get enough fluids, there shouldn’t be anything to worry about and your discomfort and headache should disappear within a short time.

For some people, headaches are a possibility when they start the Nupo Diet, because they are cutting sugar out of their diet. The headache should disappear after a few days when your body has adjusted to not eating high levels of sugar every day.

How much fluid do I need to drink?

You need to drink 2-3 litres of fluid in addition to what is found in the diet soups and shakes! The fluid in these meals does NOT count towards the 2-3 litres.

The reason that you need to drink at least 2 litres of fluid is that this helps to keep your digestive system running and reduces the risk of discomfort during the diet – and it also helps to give you a sense of fullness, particularly during the initial period where your body is getting used to less and different food.

I experience a lot of gas when I have eaten Nupo

Due to the high fibre content in Nupo, you may experience gas. This is normal and simply a matter of your body getting used to Nupo.
