5-Factor Diet: What is it and how does it work?

The 5-Factor Diet: Invented by celebrity trainer Pasternak, this diet is highly significant when it comes to the topic of losing weight. The principle of this diet if given in the name itself: everything revolves around the number 5. It is a 5 week diet, in which you eat 5 small meals a day. These should then only consist of a maximum of 5 ingredients from 5 different food groups and should take no more than 5 minutes to prepare. The exercise included in this programme is also based around the number 5: a 5 minute workout should be carried out 5 days a week. The principle behind this is as follows: by distributing the food over 5 small meals that are spread throughout the day, the metabolism is stimulated and the blood sugar level remains constant and does not succumb to any large fluctuations. This also staves off hunger. These meals are divided into three main meals – breakfast, lunch and dinner, plus two snacks – one in the morning and one in the afternoon. In total, the calorie quantity of the five meals should amount to 1300 kcal a day. The time of intake is irrelevant. There is only one rule: no food after 7 o’clock. The 5-Factor Diet is therefore a rather strict programme. However, in order to maintain motivation, it offers a “cheat day” once a week, during which you can treat yourself and do not have to exercise.

What is allowed in the 5-Factor Diet and what is not?

Allowed Not Allowed
Low fat proteins (e.g. poultry) Sweets
Fibres (e.g. whole grain and vegetables) Sugar Drinks
Long-chain carbohydrates (e.g. whole grain) Alcohol
Healthy fats (e.g. olive oil, linseed oil)

For whom is the 5-Factor Diet suitable?

  • The basic version of the 5-Factor Diet provides 120 dishes, but the internet is full of more recipes that follow the criteria of the 5-Factor Diet. The diet can be carried out by healthy people of any age who have the time and motivation to prepare the majority of the meals themselves and carry out the supplementary exercise programme.
  • However, for athletes and people who do a lot of exercise, the recommended calorie level of 1300 kcal could be too low. Therefore the 5-Factor Diet is not suitable for this target group.
  • For the average person who just wants to lose weight, nothing stands in the way to success with this diet.

Advantages and Disadvantages of the 5-Factor Diet

Advantages Disadvantages
The 5-Factor Diet offers a wide variety of recipes, as no specific foods are prescribed. Having 5 meals a day might seem like a good thing, but it could be an obstacle – especially for working people. Many lack the time to prepare and eat 5 meals a day.
The menu is very varied and can be extended to the whole family. The amount of calories and nutrients are not individually adapted to the dieter.
The 5 meals a day sufficiently and continuously supply you with nutrients and any tiresome pangs of hunger are staved off. The diet focuses on calorie and fat reduction, a combination that studies have shown often leads to that diet being abandoned. The distribution of nutrients with a high carbohydrate content is questionable, even if sugar is avoided.
Also a cheat day is planned, during which there are no rules and you can feast to your hearts content. You must always track the calories in your meals in order to not go above the preset calorie limit of 1300 kcal. A single cheat day that gets out of hand can strongly influence the whole week, so having some rules for the cheat day would be useful.
Pre-designed and balanced exercise is already integrated into the programme. The integrated training programme contains quite demanding exercises that cannot be completed easily by beginners or people who are very overweight. The sudden change of daily exercise could be an obstacle.Hindernis darstellen.

5-Factor Diet in Detail

How individual is the 5-Factor Diet?

◆◆◆◆◇ (4/5)
  • The 5-Factor Diet specifies 5 meals a day made from a maximum of 5 ingredients. The five basic rules of the diet determine which foods are used, a wide range of which are allowed. The diet book provides 120 dishes to choose from, but there are now countless recipes circulating on the internet that follow the basic rules of the 5-Factor Diet.
  • Therefore the 5-Factor Diet can be used alongside other special diets like vegetarianism and veganism.
  • It specifies a daily calorie intake of up to 1300 kcal. For many people this amount is not optimal for losing weight, however the diet is not customised to individuals.

How flexible is the 5-Factor Diet?

◆◆◇◇◇ (2/5)
  • There are set times throughout the day, including meal times. After 3pm, no more carbohydrates are allowed and after 7pm, no more food should be consumed at all. This means that you are tied, which limits flexibility.
  • For workers, planning and preparing 5 meals a day may be too time consuming.
  • In addition to this, a 5 minute workout should be carried out 5 days a week.
  • Preparing 5-Factor meals is quite simple. Eating out, on the other hand, could be a little difficult.

How suitable is the 5-Factor Diet for everyday?

◆◆◆◇◇ (3/5)
  • The implementation of the nutrition plan is very possible, it just requires a little time. For some recipes, ingredients could be harder to find and may not be available in smaller supermarkets, e.g. quinoa and udon noodles.
  • Cooking for groups or families is no problem.
  • Finding time to prepare the 5 meals a day could be difficult.

How scientific is the 5-Factor Diet?

◆◆◆◆◇ (4/5)
  • From a nutritional point of view, there is nothing wrong with the 5-Factor Diet at first glance. It is based on a healthy and balanced diet.
  • The diet is somewhat heavy in carbohydrates, but contains sufficient protein and fat.
  • Avoiding carbohydrates after 3pm when a lot of carbohydrates have already been consumed beforehand is questionable with regard to blood sugar management and nutrient timing. This recommendation is based on a nutritional myth and does not comply with the function of nutrients.
  • Since the food is catagorised into 5 groups, the dieter is sufficiently supplied with all vitamins and nutrients. However, the prescribed calorie intake could be too low.
  • The prescribed calorie intake may be too low.

How sustainable is the 5-Factor Diet and what risks does it entail?

◆◆◆◆◇ (4/5)
  • The average weight loss for someone on the 5-Factor Diet is 1.5 – 1kg a week. This is a perfectly healthy and acceptable pace. However, whether this is acheived or not depends on the dieter’s requirements, as the diet cannot be customised.
  • However, this programme is not suitable to be carried out on a long-term basis. The daily recommended amount of calories of only 1300 kcal is not enough in the long-term and should be slowly increased to a normal level at the end of the 5 weeks. It is important to slowly get your body used to a higher calorie intake again in order to avoid the yo-yo effect.
  • There are no health risks when following the 5-Factor Diet. The 5 specified food groups mean that you are sufficiently supplied with nutrients and deficiency symptoms do not occur.
  • The cheat day carries the danger of slowing down the diet considerably if the calorie intake is not kept within reasonable limits. Continuing with the cheat day after the 5 weeks is not adivsable.

Conclusion and Rating

On the whole, the 5-Factor Diet is a good basis for a healthy, balanced diet and moderate weight loss. You are sufficiently supplied with all necessary nutrients and there are no deficiency symptoms. If the fairly low calorie intake is adjusted individually, the diet can be carried out permanently. Based on this, our overall assessment is as follows:
