What is the 5:2 diet?


Eat normally for five days and fast for two days a week.

The 5:2 diet has recently become very popular. It entails eating normal, healthy food five days a week and fasting two days a week. On fast days you should eat only 500-600 kcal (calories) per day – 500 kcal for women and 600 kcal for men.

What should I eat on fast days?

On fast days, your calorie intake should only be 500-600 calories, which is about one quarter of the normal number of calories eaten per day. It is therefore extremely important to have good control of the amount of calories in the foods you choose to eat.

Vegetables have very few calories, but are rich in nutrients like vitamins and minerals. Drinking substantial amounts of water is also very important, not only to avoid dehydration but also because it fills your stomach and makes you feel less hungry.

Otherwise, eating products like Nutrilett bars is excellent on fast days as they give you good control of the number of calories you are eating while also ensuring that you obtain important nutrients like protein, fibre, vitamins and minerals.

How can I use Nutrilett while I’m on the 5:2 diet?

It’s fine for you to use Nutrilett bars while on the 5:2 diet. The bars give you good control of the number of calories that you eat per day. One bar contains between 200 and 220 kcal. You can therefore eat 2-3 bars along with vegetables and a lot of water and still stay within the 500-600 kcal limit on fast days.
