And by the second season, as planned by the director, Polina Grenz lost weight. How did she manage to lose weight so quickly and become a role model for millions of teenagers? In order to lose weight in the shortest possible time and return to her previous shape, the girl needed to gather her willpower into a fist and arm herself with strong motivation.

Biography of Polina Grenz

Polina Grenz, whose photo is popular among fans of Russian cinema, was born on October 28, 1994 in the family of a housewife and a service station owner. Being a native Muscovite, the girl knew from an early age what show business was and wanted to get on TV.


During her school years, Polya took part in school amateur performances, and not a single holiday was complete without her. The girl sang, danced and participated in theatrical productions. Looking at heroines from movies, she dreamed of becoming an actress someday, and even started her own blog on YouTube.

On her channel, she spoke with subscribers on various teenage topics and was very popular among her peers. The online audience noted that Polina behaves naturally in front of the camera and reveals interesting questions.

Polina is the eldest child in the family. In 2010, she had a younger sister, Margarita. Grenz grew up an obedient child and an exemplary student. She tried to carry out all important assignments and obey her elders.

After graduating from school, the star of the series “Fizruk” decided to connect her life with acting and wanted to enter the theater school. But the parents said their decisive “No!”, because they believed that acting in films and on stage is not a profession, but a hobby. Grenz had no choice but to enroll in sociology at one of the capital’s universities.

But the girl did not give up her dream of cinema, and at the same time enrolled in a theater studio, where she studied in her free time from her main studies. One day a photographer came to them and took pictures of their group. After some time, Polina received an invitation to the casting of a youth series. The girl later noted that she went to the audition not because she was confident in herself, but because she was called.



In 2013, work began on the creation of the cult series about school everyday life “Fizruk”, and a year later Polina woke up famous. The role of the plump truth-seeker Sasha Mamaeva, nicknamed “Naf-naf,” brought her fame. Later, the star admitted that until recently she did not believe that she would be approved, and before that she went to various auditions, but it did not bring results.

The 25-year-old girl believes that Dmitry Nagiyev, the main character of the multi-part film, played a decisive role in her creative life.

It turned out that he approved Grenz a few minutes before the start of work on the TNT project, noting that she was real and not as mannered as the other contenders for the role of Alexandra.

Now Polina, who never graduated from the theater school because she did not come to the exams, continues to conquer the Russian Olympus of show business, starring in various television projects and 1 theatrical production.

She has worked in:

  • “Fizruk” (season 1-6);
  • “Let Them Talk” (TV show);
  • "Mommies";
  • "Shoes";
  • “Being a Blogger” (TV show);
  • "Oracle: Game in the Dark";
  • “The Bachelor” (season 7) (TV show);
  • “Snow in a foreign city” (play);
  • "Rate Robbery";
  • "Tete-a-tete."

In the film “Mommies,” released in 2021, Polina played saleswoman Yana, and in the short film “Shoes to the Last Drop of Blood” she played one of her friends. In “Oracle: Game in the Dark” she was given an episodic role, and in “The Tariff Robbery” she was given the main role, Grenz plays Marina. When the short film “Tete-a-Tete” is released, it will be possible to evaluate the work of the actress in the role of Svetlana.

In addition, the girl worked as a TV presenter in the program “Being a Blogger” and performed on the theater stage in the play “Snow in a Foreign City,” where she played the role of the beloved of the protagonist’s youngest son.

Brief background

For the first time, the news about Polina Grenz's dramatic weight loss broke during the filming of Fizruk, when the actress, in her interview on the talk show Let Them Talk, shared the secrets of how she managed to get rid of annoying wrinkles without resorting to “magic” weight loss pills .

Her story with extra pounds dates back to the period of casting for the series “Fizruk”, where in order to get the role of Sasha Mamaeva, the girl needed to gain weight. According to Alexander’s script, “Naf-Naf” is an appetizing, rosy-cheeked girl.

Polina reports that the decisive decision in approving the main role of the heroine was made by D. Nagiyev, in his opinion Polina had all the necessary qualities for the role of Alexandra.

The main character noticed simplicity and naturalness in the chosen candidate, while the other participants looked too “studied” compared to her. The aspiring actress easily agreed to the conditions and gained extra pounds in a short period of time.

Personal life

Polina Grenz, whose photo can be seen in many virtual publications, is an Instagram star. Subscribers are sure that the 25-year-old actress has many fans, but the girl herself does not comment on this information.

During the screening of the TV show “Fizruk,” Grenz’s followers thought that she was having an affair with her colleague on the set, Artur Sopelnikov, who played Anton Borzykh in the series. But this turned out to be not true, and Polina herself denied the rumors. She later admitted that she fell in love with the lighting designer, and he reciprocated her feelings. The young people lived together for some time.

Later, the girl was seen at a social event with Mikhail Polovenko. When asked about her relationship with the actor, Grenz responded with silence. The TV star also appeared on the network with blogger Vlad Berenich. The star tries not to advertise her personal life, which continues to stir up the interest of fans.

During her entire time working on the set, Polina was credited with having affairs with:

  • Arthur Sopelnikov;
  • Dmitry Nagiyev;
  • Dmitry Vlaskin;
  • Mikhail Polovenko;
  • Vlad Berenich.


None of the options was ever confirmed by the actress. Among her colleagues, Polina is considered a serious girl who is not interested in fleeting hobbies.

Diet tips

To switch to the chosen diet, it is recommended to consult a specialist. While working on the daily diet and duration of the diet, the dietitian must monitor the health status. A number of dietary restrictions can lead to exacerbation of chronic pathologies or negatively affect metabolism.

After 18.00, the young celebrity tries not to eat food, but will not deny herself a glass of kefir or juice. Fasting is excluded. To speed up the process, it is recommended to create 1 fasting day per week, not excluding the consumption of juices or kefir, and alternating them.

It is important to remember about age-related characteristics and chronic diseases, if they occur. Doctors also pay attention to genetics: if there are people in the family who are overweight or have chronic diseases, the diet can lead to negative consequences.

Star appearance

Photos of the thinner actress Polina Grenz flooded the network, and fans are amazed at the changes that have happened to their idol. With a height of 160 cm, the girl now weighs 51 kg.

The star willingly shares the secret of losing weight and notes that she started getting in shape after filming season 2 of Fizruk. The impetus for losing weight was the moment when she saw herself on the screen and realized that “a public figure cannot look like that.”

The girl limited herself to sweets and starchy foods, and also began visiting the gym. After some time, Polina noticeably lost weight, and told fans that she had lost 16 kg.

The weight loss was followed by a radical change in image. From a pleasant brown-haired girl the girl turned into:

  • brunette;
  • blonde;
  • redhead.

Fans reacted positively to the change in hair color, noting that the star was looking prettier before their eyes. When Polina dyed her hair brunette, comments appeared on Instagram that she looked more beautiful and sexier this way.


More than once the girl appeared in photographs with drawings on her body and hands. Assumptions that this tattoo turned out to be false, since the star periodically likes to apply mihendi and temporary body art to her body.

The basics of a balanced diet star

Polina’s diet was structured in such a way that the body received a sufficient amount of slow (complex) carbohydrates in the morning, protein foods at lunch, and more fiber and a little more protein for dinner.

The main ingredients of the actress's diet: chicken breast and sea fish (cooking methods: boiling, steaming, stewing, baking), fresh vegetables, seaweed, as well as all kinds of fruits.

A total ban on: salty and spicy foods, processed foods, mayonnaise and ketchup, potatoes in any form, as well as sweets, flour and confectionery products.

Acceptable product: dark chocolate with high cocoa content.

When and why Polina Grenz had to increase her weight

Polina Grenz, whose photos of her slender figure encourage many girls to take care of their bodies, at the beginning of her career could not be called a “fitness model.” During her school years, the star did not have a lean physique, but did not have any complexes about it.

The producers of the sitcom “Fizruk” forced Polina to take a fresh look at herself, setting the condition for the future Sasha Naf-naf that she gain weight and become curvy before filming began. The Muscovite agreed to the experiment with weight without hesitation.

To quickly gain weight, the future star ate up on chocolate ice cream and did not limit herself in baking . In addition, Polina had a special foam overalls made, which she wore under her clothes before each shoot.

The girl noted that after gaining weight she felt uncomfortable on the beach and in public places. She was very happy when the script for one of the seasons included Sasha Mamaeva losing weight.

Interview with Andrey Malakhov

“During the TNT presentation, I had to answer the questions: “Is that you?”
— the actress shares. – In response to the offer to try delicious delicacies, I just smiled. I happily wear a tight dress and don’t worry about my belly or extra folds on the sides. It looks perfect!” “I want to be fragile and feminine”

— TV viewers are impressed by your plump, charming heroine. Why did you decide to radically change your appearance?

- For myself. I want to become fragile, slim and feminine.

Try on a dress that accentuates your figure rather than hiding it. I have not yet achieved the desired result, but I do not stop there.

I want to feel charming in different images. I still have time to recover.

About 5 years ago I had ideal parameters for my height of 161 cm, and then I gained weight. For the role, she added additionally - she ate chocolate ice cream in immeasurable quantities.

- What is the limit of your dreams?

— I haven’t decided yet. I look at myself in the mirror and realize: there is still a little left.

Now I strive for healthy nutrition - I try to exclude sweets, flour products and processed foods. Instead of sausage, I consume vegetable and chicken dishes cooked in a steamer, and low-fat soups.

At the beginning of the diet it was difficult to come to terms with the new diet, but then I got used to it. When we look good, we ourselves enjoy it.”

Plastic surgery

Lately, fans have not recognized Polina, noting noticeable changes in her appearance. Her followers were accustomed to the fact that the actress kept herself in shape, but they couldn’t help but notice that the girl resorted to the help of plastic surgeons.

Grenz changed:

  • cheekbones;
  • nose;
  • lips;
  • chin.


The actress’s cheekbones became sharper and more distinct, and her nose took on a more refined shape compared to the photo of Sasha Mamaeva.
In addition, the TV presenter adjusted her chin, making it softer and smaller. Following modern fashion trends, Polina plumped up her lips. Now they are even plumper than they were. She herself admitted that the blogger resorted to the help of plastic surgeons. The girl was prompted to decide to change her appearance by psychological problems related to her personal life.

It turned out that the last breakup with the young man was so painful that the psychologist advised Grenz to change, and she understood the advice that way. Now Polina sees a new self in the mirror and does not associate her past unsuccessful love experience with the reflection.

The beginning of the way

One day, luck switched to the side of a young girl. People who were casting for a series on the TNT channel came to the theater studio. They photographed young girls in order to then select from the photographs the one that would best suit their appearance. This is what Polina became. She was invited to go through the 2nd round of casting, to which she agreed.

Having seen the actress, the main star of the project, Dmitry Nagiyev, realized that she would be ideal for the role. However, she was required not only to give her consent, but also to fulfill an additional condition. The point was that Polina had to change her appearance for the role, and more specifically, gain a few kilograms.

Her debut character was Sasha Mamaeva, an insecure school student. As Grenz later said in an interview, this role in Fizruk was easy for her. Sasha was close in spirit to Polina herself, so her performance in the project was genuine and sincere.

Polina behaved well in the frame and was not afraid of cameras, which to some extent was due to experience. Before that, she had not acted in any films, but she kept a personal blog dedicated to relationships. Now it is impossible to find videos shot by the girl at that time, because the channel has long been deleted.

A few years later, Polina had to leave the university and change direction. This time her choice fell on the Faculty of Economics. The reason was that the previous university did not allow the girl’s time to be organized in such a way that she could attend both classes at the university and the film set.

For Polina, transferring to another university was not bad news, because she considered the most important thing to be that she had finally fulfilled her dream. After filming season 1 of Fizruk, the producers announced the release of a new season. It was obvious that the role of Sasha Mamaeva would be assigned to Polina Grenz, whom both the film crew and television viewers managed to fall in love with.

Cosmetology procedures

Once in an interview, Polina noted that she used to be afraid of cosmetologists. This is due to the fact that in adolescence the girl developed acne, which she decided to get rid of with the help of a specialist. After undergoing a facial cleansing procedure, the Muscovite was horrified; within 24 hours, acne attacked her face with renewed vigor.

The girl was able to overcome her fear by playing in the sitcom “Fizruk”. Due to the constant application of makeup, the face of the TV schoolgirl was covered with a rash, which was impossible to get rid of at home on her own.

Colleagues at the site advised Grenz to go to a good cosmetologist and gave her the address. It turned out that a highly qualified specialist worked there and quickly helped the aspiring actress solve the problem. After this, the girl stopped being afraid of cosmetic procedures.


Fans of the series “Fizruk” noticed that not only individual parts of Polina Grenz’s face have changed, but also its shape. It turned out that the star visited one of the capital’s clinics, where she underwent non-surgical correction of her facial contours.

The “Slim Face” procedure was performed on the actress personally by the leading doctor of the institution. With the help of such a correction, any part of the body can be changed, while the patient does not sleep, as during surgery, but actively participates in the process.

Legends from the Internet

The names of famous people are often used by scammers in their advertising, wanting to sell more goods. This also affected Polina Grenz. One day, the star woke up and found out that she was not only popular as an actress, but also the face of several weight loss products of dubious origin. Today Mamaeva from the TV series “Fizruk” advertises goji berries and super-chewing gum for weight control. Polina herself refuses to comment on the situation and does not try to fight people who unauthorizedly use her photographs. It is not known for certain whether the actress tried the above-mentioned food additives. The fact remains obvious that even their use does not guarantee such fast and high-quality weight loss.

Star photo shoots

Polina Grenz, whose photos are a motivator for working on herself, has recently not been afraid to appear in swimsuits and revealing outfits. This is due to the dramatic weight loss of the actress and her good physical shape.

The slimmer the actress becomes, the more she bares herself on her Instagram page. The photo of the girl in underwear and home clothes caused a stir among subscribers.

Polina posted the photo dated March 25, 2021 with deep philosophical overtones, asking subscribers what love means to them. The Internet public reacted with irritation to the positive and lyrical attitude of the actress.

Followers asked why it is fashionable to caption photos in bodysuits with text containing philosophical reflections. There were also those who asked about “why thoughts of lofty things come when you take off your outerwear.”

Despite the humorous caption to the photo dated March 15, 2021, that the actress “wanted to get the pasta, but her neck was pinched,” fans reacted negatively to the idol’s perfect body. Subscribers accused Polina of going too far with Photoshop, noting that the waist area had clearly undergone computer correction.

The photo taken on November 27, 2021 cannot be called “naked,” but it received a lot of negative reviews. This is due to the fact that Grenz is constantly photographed with her legs spread and subscribers wondered why she does this. People noted that the pose looked vulgar and did not suit Polina.

Photo from May 24, 2021, followers commented that they always liked her, even when she was plump Sasha Mamaeva . At the same time, there were those who said that she was better off plump, but now she has lost her individuality.

The Internet community was also intrigued by the caption to the post, which read a message to some man.

The photo was taken on February 3, 2021. Followers liked it and wrote how good Polina looked in a swimsuit. But there were also those who were dissatisfied with her appearance, noting that more time should be devoted to the back of the body.

On May 5, 2021, Grenz posted 2 photos of herself on the social network, where she compared herself, who had lost weight, with herself in the image of Sasha Mamaeva. Most subscribers were pleased with what they saw, but there were also those who reacted negatively to the reduction in breast volume.



On July 18, 2021, the actress added a photo to her page in a black tight-fitting evening dress with a deep neckline. The photo did not leave fans indifferent, and they noted that Polina looks very sexy and tempting.
But some users drew attention to the saggy shape of the girl’s breasts, noting that in this photo she looks 40. The 25-year-old TV star loves to wear blouses and dresses with a deep neckline. Fans have written more than once that even while singing, the viewer’s attention switches to Polina’s breasts, which distracts from her work. Despite this, Grenz knows how to look touching and, when going out in public, does not overstep the bounds of decency. The actress's outfits are always appropriate and correspond to what is happening around her.

Let's look at what helped the celebrity get into shape.

Help from a nutritionist

Without nutritional correction, as thin Polina admits, she would not have been able to become what she is now. The actress decided not to experiment with ready-made diets and turned to a nutritionist.

She received the following professional recommendations:

  • Ban on fried, fatty, fast food, sweets, baked goods, potatoes, salty and spicy foods. All these products either quickly turn into fat, or cause appetite, or retain water in the body, so they are strictly prohibited for those who want to become slimmer. Polina can only treat herself to a couple of pieces of dark chocolate without additives in the first half of the day, but even then she perceives the delicacy as a special gift.
  • Fractional meals. We lose weight when our metabolism speeds up. To do this, you need to eat often, but in small portions. A full meal should consist of 200 g of food, no more. The actress eats 5-6 times a day, because her body actively uses energy and does not store it “in reserve.”
  • The right foods for lunch, breakfast and dinner. In the morning, Polina eats porridge, as they are rich in slow carbohydrates, which charge us with energy . Lunch should include lean fish or meat - a source of protein. The method of preparing them matters - only boiling, stewing or steaming is allowed. The actress's dinner consists of fiber-rich foods. These can be vegetables and herbs, fresh salads.
  • Much water. In the morning, Polina drinks a glass of still mineral water on an empty stomach, and another 7 glasses throughout the day. She tries to drink 20 minutes before meals and 40 minutes later. This helps to avoid swelling, remove toxins and waste from the body, and start metabolic processes. It is better to drink the last glass no later than 19.00, so as not to see a swollen face in the mirror in the morning.
  • One loading day per week. Polina is not completely deprived of gastronomic joys; once every 7 days she can afford any prohibited product, but only until 16.00.
