A real breakthrough in nutrition! A slim figure, health and a halt to the ageing process. All this is promised by the SIRT diet. It sounds fantastic, but is it possible?

.

If the subject of weight loss is close to your heart, you have heard about such wonderful diets many times. So far, we only have studies on yeast, fruit flies and mammals to confirm these claims. And then there's Adele's remarkable transformation. That's why, with nutritionist Kuba Pągowski, we check out whether the SIRT diet is hit or putty.

.

From this article you will learn:

.
  • What the sirtuin diet is and what its principles are.
  • .
  • What the mysterious sirtuins are.
  • .
  • What foods are recommended in the SIRT diet.
  • .
  • What stages the sirtuin diet consists of.
  • .
  • Whether it is healthy and supported by scientific evidence.
  • .
  • How to prepare dishes and cocktails in the spirit of sirtfood.

What is the sirtuin diet about?

The SIRT diet was created by Aiwan Goggins and Glen Matten, who introduced it in 2016 in their book. The diet involves a four-step nutrition programme that relies on sirtuin-rich foods and involves activating them in the body. It aims to activate the genes of slimness and longevity.

In a nutshell, the premise of the diet can be said to involve replacing certain meals with green smoothies that are prepared from the best sources of sirtuins.

What are sirtuins?

.

Sirtuins are proteins found in virtually all living organisms - from yeast to humans and other mammals. Among other things, they are responsible for cellular metabolism (i.e. the chemical reactions and energy metabolism necessary for cell function). Recent studies suggest that sirtuins may also have an effect onand:

    .
  • the body's response to oxidative stress,
  • .
  • metabolic transformation,
  • .
  • shutting down the expression of certain genes,
  • .
  • activation of DNA repair mechanisms,
  • .
  • anti-cancer effects,
  • .
  • slowing the rate of ageing in the body,
  • .

Sounds really great, however, it is worth noting that the functions and mechanisms of action of sirtuins are not fully understood. Most of the studies that scientists are relying on at the moment have been conducted either in vitro or in yeast and animalsand.

.
It is also worth adding that we could attribute the above properties to many substances we find in food, e.g. fibre (which, compared to sirtuins, has a strongly proven anti-cancer effect, among other things), so in my opinion, the super functions of the SIRT diet are worth approaching with caution.

Although sirtuins certainly have potential in the fight against diseases associated with ageing, at present the quality of evidence is clearly insufficient to proclaim a nutritional breakthrough.

Principles of the SIRT diet

.

The basic principle of the SIRT diet is to compose meals using 20 foods that, according to the authors, are the best sources and activators of sirtuins. However, the matter is not so simple.

Research shows that sirtuins are best activated with calorie restriction. According to various sources, we are talking about a 20-50% cut in dietary kilocaloriesand. Therefore, the authors diet have divided it into four stages, with the initial two involving a significant calorie reduction in meals.

Another distinctive feature of this diet is the replacement of some meals with sirtuin shakes. This is such a more green name for green vegetable smoothies.

What foods should be eliminated from the diet? The diet's authors recommend getting rid of white flour products (bread, pasta), sweets and processed foods (to fast food, chips, finger foods, etc. we say pa, pa).

Stages of the sirtuin diet

.

On the SIRT diet you are likely to feel hunger pangs initially due to the low kcal supply of the diet, but fortunately only for the first few days. For many people, this will be the hardest stage to survive.

See how the diet plan goes:

Stage 1

.

Duration: 3 days

What to eat: 1 full meal + 3 green smoothies

Calorie limit: 1000 kcal

In the first stage, sirtfood-based shakes form the basis of your nutrition, supplemented with one normal meal (which should also contain SIRT products). In addition, remember to hydrate - drink water, matcha, green tea.

Step 2

.

Duration: 4 days

What you eat: 2 full meals + 2 green smoothies

Calorie limit: 1500 kcal

Steps 1 and 2 take up the first week. Once you've survived it, there's an end to the torturous kilocalorie cutting.

Estage 3.

Stage 3

.

Duration: 14 days

What you eat: 3 full meals + 1 green smoothie

Calorie restriction: none, but rather tailored to your calorie requirements

For the next two weeks, you replace at least one meal with a green smoothie. The authors no longer impose a calorie restriction, but in order to continue losing weight, you need to calculate your energy requirements and reduce them accordingly to achieve a calorie deficit.

Step 4

.

Duration: as much as you want - preferably permanently

What you eat: what you want - tailored to your individual needs

Calorie restriction: none, but rather tailored to your calorie requirements

After three weeks of being led by the hand, the authors of the diet give you freedom. You can eat as many meals a day as you're comfortable with, and you don't have to replace them with green smoothies (although that's welcome, of course). The only thing you need to be guided by when preparing food for yourself is that it should be prepared with as many of the 20 sirtfoods as possible.

Of course, it probably won't be that simple, because in order to continue losing weight, in practice you will still need to adhere to a calorie deficit (especially if you have a little more than a few&bsp;super sirtfood kilograms to lose).

Important

Remember that there is no such thing as a "safe dose of alcohol". Even small amounts of liquor, drunk regularly, are detrimental to health. Red wine used to be looked upon more favourably because of its content resveratrol. Is this right? There are 2 mg of resveratrol in one litre of this alcohol. According to research, the portion that is beneficial is around 5 mg. For red wine to provide you with the right dose of this substance, you would need to drink 2.5 litres a day. That sounds like a serious alcohol problem...

.

Is the sirtuin diet healthy?

.

Good question! And the answer can be boiled down to: it depends.

The SIRT diet certainly has all the qualities to become fashionable

.

  • restrictive calorie restrictions (in the initial stages),
  • .
  • the illusion of being able to eat as much as you want (in subsequent phases),
  • superfoods.
  • superfoods that have some there, indirect basis of action derived from scientific research
  • .
  • and, above all, its star - Adele - who is said to have lost as much as 40 kilograms on it.

The singer admits, however, that her metamorphosis wasn't just down to the diet - she added a solid workout to it. I don't want to play with insinuations straight from the gossip portals, but it also seems unlikely that the singer relied solely on the SIRT diet book and didn't have the help of a nutritionist.

.
It is worth pointing out that there are a number of routes to achieving a goal (in this case fat reduction), but not all of them are healthy or optimal.
.
Kuba Pągowski.

.

Well, let's leave Adele alone and look at the assumptions of the diet itself. And you can see some red flags in them.

Red flags of the SIRT diet

.

Firstly, the diet at the initial stage involves restricting caloric supply to 1000 kcal. A healthy caloric deficit used in reduction diets involves limiting calorie supply by an average of 200-500 kcal (in very obese people this may be more)and.

The intricate meanderings of a caloric deficit are explained by an expert:

.

.
The more overweight or obese a person is, the larger deficits we can make due to the greater utilisation of fatty acids. In addition, faster weight reduction is good for the head and motivation.
.
Kuba Pągowski.

Kuba Pągowski clinical dietitian

.

A such a small daily kilocalorie supply as 1000 kcal could only work well for people whose caloric requirements are 1500 kcal and less, although it should be noted that they are not usually given a 500 kcal reduction...

But what if your requirement is 3000 or 4000 kcal? For the first three days you'll basically be starving yourself. And for the next four, it won't be much better. 

Too much of a calorie deficit can lead toand:

      .
    • fatigue,
    • .
    • concentration problems,
      • .
      • hunger attacks,
      • stress.
      • drawal of energy from muscles,
      • .
.
Particularly cautious with the SIRT diet should be people with diabetes, who are at risk of extremely low blood sugar levels when eating low-calorie foods for long periods of time. It is therefore advisable to monitor sugar levels carefully when following similar diets.
.
Nina Król

Nina KrólManager of Content Promotion and Nutritionist at Natu.Care

.

Outside of this, the scientific research talking about reducing kilocalorie supply to activate sirtuins assumes supplying the body with essential vitamins and minerals. This can be hard to control at homeand.

Secondly, in the initial stages, rapid weight loss is likely to be mainly due to water loss rather than fat loss. This is the case with all diets with restrictive calorie assumptions.

Thirdly, the assumption that after three weeks you can basically eat as much as you want as long as your meals contain 20 superfoods is, to put it mildly... questionable. By supplying yourself with an excess amount of kilocalories, your body weight will not fall, but will actually increase - even if they come from the world's healthiest foodand.

.
The healthiest and most beneficial in terms of learning to be nutritionally aware would be to start with stage 3, which is a diet tailored to your lifestyle, with a sensible reduction in calorie intake.
.
Kuba Pągowski.

      .

Thirdly, although the SIRT diet does eliminate carbohydrates, there are not many of them among the recommended foods. And you need these, and many experts do not at all recommend limiting their intake beyond the norm. Of course, it's worth eliminating the processed ones - such as those from sweets, but... let's be human - we all deserve a cake or a bar from time to time. So-called  comfort food is also part of a balanced dietand.

It cannot be said, however, that the SIRT diet is alone evil. Both the 20 products supposed to activate sirtuins and the other ingredients recommended in it are healthy and certainly worth making a significant part of your menu. However... their consumption is also assumed by other, much healthier and more balanced diets, such as the Mediterranean diet.

      .

There is nothing wrong with green smoothies either, and drinking them for a second breakfast is a nice idea for a healthy and tasty meal. Plus, they are quick to prepare and easy to take to work or on a trip. In addition to vitamins, micro- and macronutrients, they will also aid hydration.

Will sirtuins really prolong your life and guarantee you the figure of your dreams? Perhaps. It's hard to tell from studies on fruit flies, mice or orangutans. However, it is certainly worth ensuring that vegetables are the basis of your meals - including those mentioned by the authors of the SIRT dietand.

.
An undoubted advantage resulting from the SIRT diet is the inclusion in the diet of a specific amount of vegetables and fruit, which are often missing from the diet of Poles.

SIRT diet - effects

      .

Theoretically, the effects of the SIRT diet, apart from weight loss, are supposed to be: prolongation of life, reduced risk of ailments related to ageing and civilisation diseases, as well as support beauty - healthy, radiant complexion, shiny hair and strong nails.

      .

However, it's important to remember that if you're on too much of a calorie deficit, it's your hair and nails that will take a hit first.

And how much weight can you lose on the sirtuin diet? It is said that you can lose as much as 12 kilograms in 3 weeks on the SIRT diet, but as you may have guessed, I have not found any studies to confirm this.

Additionally, such a large and rapid weight loss is not at all healthy and can lead to a loss of firmness in the skin, which does not have time to shrink. The correct weight loss should be between 0.5-1 kg per week. Such a loss minimises the risk of yoyo effect and sagging skinand.

The sirtfood diet - nutritionist reviews

      .

Dietitian Jakub Pągowski says this about the SIRT diet:

      .

"In my opinion, the SIRT diet - like any other fad diet - is over-hyped and does more harm than good. It doesn't teach healthy eating habits, it relies (in the early stages) on huge restrictions, and ultimately doesn't explain the how, why and what determines healthy fat reduction. By far the better, healthier option is the classic, individual calorie deficit diet, based on as many products as possible."

Clinical nutritionist Aleksandra Cudna-Bartnicka:

"The biggest drawback of this diet is definitely its phase I, which involves taking in less than 1,000 kcal per day. This is a very high caloric restriction, which will actually produce some weight loss results, but it will be mainly water, glycogen and a small amount of body fat.

There is also the need to remember that the diet is not a good one.

It is also important to remember that low calorie diets cause the body to become accustomed to the new low calorie diet and a return to a regular diet may end up with even more excess pounds. 

The SIRT diet without the first phase can, however, have beneficial health effects due to its high antioxidant potential and anti-inflammatory nature."

Clinical nutritionist and personal trainer Marta Kaczorek:

      .

"I believe that despite its effectiveness in weight loss, the SIRT diet is not a good solution. It is all about severe calorie restriction in its first phase, although the second phase can also be severely calorically deficient.

This can do a lot of harm, especially for people who haven't tested themselves before and don't know what health ceiling they are starting from. However, what I like about this style of eating, is eating a lot of polyphenol-containing foods and as much fresh, unprocessed produce as possible."

The SDS diet is a good way to get a good idea of what you're eating.

FAQ

.
. How much weight can you lose on the SIRT diet? .

Depending on individual characteristics, on the SIRT diet you can reportedly lose up to 3 kilograms in the first week and up to 12 kilograms in three weeks. However, it is worth noting that this is much more than the experts recommend. A healthy weight loss should be 0.5-1kg per week.

. What is the SIRT diet about? .

The SIRT diet, is based on products rich in sirtuins - proteins that help regulate metabolic processes. Its main principle is to consume meals and green shakes prepared from 20 products to activate sirtuins in the body.

The diet consists of four stages. During the first two, it assumes a strict restriction of calorie intake. During the next ones, you can theoretically eat as much as you want.

.
. Who has lost weight on the Sirtfood diet? .

The SIRT diet became widespread thanks to British singer Adele, who was said to have lost as much as 40 kilograms on it. It is worth mentioning, however, that the star herself admitted that she supplemented her dietary changes with an intense workout.

. Is it okay to drink coffee on the sirtuin diet? .

Yes, you can drink coffee on the sirtuin diet. Include it in your daily menu as it contains polyphenols, which are thought to activate sirtuins. Polyphenols are a key ingredient in the sirtuin diet, known for their anti-ageing properties. However, avoid adding sugar or cream to your coffee.

. How long does the Sirtfood diet last? .

The SIRT diet involves permanent changes to the way you eat. Menu building is to be based on (but not necessarily limited to) a catalogue of recommended foods.
