In this article, we will answer the following topics:

What is the Sirtfood Diet and how does it work?
The Sirtfood diet is advertised as revolutionary, and that it’s just as effective as intermittent fasting in burning fat. This diet is based on research on sirtuins which are proteins that regulate metabolism, inflammation and increases lifespan .
The purpose of this diet is to consume foods that are rich in sirtfoods. These nutrients increase those proteins in the body to activate something called the ‘skinny gene’. In addition to consuming sirtfoods, the diet also includes a calorie restriction which helps you lose weight.
The sirtfood list
There has been plenty of research done on sirtfoods and the natural compounds that help to produce the proteins required for the diet to work. This diet is all about eating as many sirtfoods and sirtfood meals as possible. The sirtfood diet includes the following foods:
- Olive oil
- Red and White wine
- Matcha green tea
- Dark chocolate (85% cocoa)
- Birds-eye chillies
- Green Tea
- Medijool dates
Don’t forget to also eat your meats, and especially chicken breast or steak. You can get more information on this diet from the sirtfood diet website.
How to do the Sirtfood diet? Sirtfood meals and recipes
The sirtfood diet consists of 2 phases that last 3 weeks in total. Both phases require you to follow a specific sirtfood diet meal plan which contains specific recipes. These recipes can be obtained directly from The Sirtfood diet books only which were written by the creators of the sirtfood diet. You can also purchase the Sirtfood diet book here if you wish to get more Sirtfood recipes after you’ve completed the 2 phases.
However, the three signature ingredients required to complete the two phases are matcha green tea powder, lovage, and buckwheat. The biggest part of this diet is its daily green juice. You should drink the green juice two to three times a day. The Sirtfood green juice consists of the following ingredients:
- Half a lemon
- Half a teaspoon matcha green tea
- 2 celery sticks
- 5 grams parsley
- 30 grams rocket
- 75 grams kale
- 1cm ginger
- Half a green apple
In a juicer, not a blender, combine all of the green vegetables (rocket and kale), then add the celery and green apple. You may peel the lemon and put it in the juicer, but juicing the lemon by hand might be better. Then you can just add the lemon juice into the mixture instead. You should get about 250ml of green juice from this mixture. Pour a small amount of juice into a glass and top with matcha tea.
Make sure to follow the strict measurements for each and every one of the ingredients. It may be worth getting a juicer and kitchen scales. Also, make sure to use a juicer and not a blender, we recommend this juicer as it extracts up to 20% more juice and 30% more vitamins and minerals. In addition, it is easy to use, to clean and has a safety locking as well as an anti-drip spout. Therefore, not only will you obtain more juice, vitamins, and minerals but also keep your kitchen clean. It’s the best of both worlds for a person with a busy lifestyle. You can purchase the juicer here.
Phase 1 of the Sirtfood diet: Green Juice Phase
The first phase lasts 7 days and requires a low-calorie intake.
The week is split into 3 days and 4 days. For the first 3 days you can only consume 1,000 calories per day. Those 1,000 calories will consist of three sirtfood green juices, one sirtfood rich meal, and 2 squares of dark chocolate.
The remaining 4 days consist of 1,500 calories and require you to drink two Sirtfood green juices as well as two sirtfood-rich meals.
Phase 1 is quite strict in regards to alcohol, you MUST avoid it at all costs.
However, you can drink tea, coffee, and green tea as much as you like. Just be cautious about adding sugars and milk to tea and coffee as this adds extra calories.
Also, don’t go over the calorie intake; that’s what’s going to help you lose weight.
Phase 2 of the Sirtfood Diet
Phase 2 does not focus on calorie intake. Instead, you need to eat three sirtfood-rich meals, one to two green juices, and 1 or 2 sirtfood desserts.
The snacks are mostly optional if you are hungry. All these recipes and snack recipes are provided in The Sirtfood Diet book.
In addition, you can also drink 2-3 glasses of red wine per week, and as much as you like of water, tea, coffee, and green tea.
What happens after you finish the Sirtfood diet?
The Sirtfood diet was designed to improve your lifestyle and help you lose weight. It is not a one-off diet like any other calorie-restricted diet.
A diet rich in sirtfoods is filled with healthy foods that provide a number of health benefits like regulating your blood sugar levels, reducing risks of chronic disease, and fight inflammation.
In addition to weight loss and these health benefits, a diet rich in sirtfoods can also boost metabolism and help you gain muscle.
Therefore, you should continue drinking two to three green juices and consuming balanced sirtfood rich meals for a proper health boost and successful weight loss.
Phases 1 and 2 can be repeated as or when required so as to improve mental health or to be rectified after things went wrong.

What happens after the two phases of the Sirtfood diet?
You may repeat the two phases as often as you wish for further weight loss or you can continue including sirtfoods and sirtfood-rich meals to continue producing the proteins required to obtain the benefits of this diet. You are also encouraged to continue drinking the green juice every day.
There are many cookbooks and recipe books for the sirtfood diet, but to do it right and ensure you are doing it as prescribed by the two creators, you should purchase the original Sirtfood Diet’ book.
Does the Sirtfood diet actually work?
The sirtfood diet encourages healthy eating with a varied and balanced diet. However, it is advertised as revolutionary and superior to any other diet. Yet it barely has any evidence behind it. Let’s take a look at the way the diet is constructed and how this can affect your body.
Firstly, the diet is not like any other regular diet, and eating a diet rich in healthy and nutritious foods may protect the body against a variety of diseases.
However, 3 weeks of such dieting is simply not long enough to obtain the health benefits of those food choices.
Losing weight using three sirtfood green juices may speed up weight loss like anything else. However, it isn’t because of the sirtfood rich meals or the green juices that help you burn fat. Instead, it’s about the calorie restriction that this diet imposes.
For instance, there are no studies that prove the weight loss superiority of the sirtfood diet.
One study done by the creators included 39 participants and ran over 7 days. At the end of the 7-day period, participants had lost an average of 7lbs (3.2kgs) of weight.
However, this study is nowhere to be seen on any reputable source like Google Scholar or Pubmed which raises some suspicions.
Also, these results are hardly surprising, anyone who chooses to restrict their calories to as low as 1,000 per day and exercise is likely to lose a lot of weight.
However, in the first week of any kind of dieting, whether this is a Keto diet or fasting, only 1/3 of that weight loss comes from fat. The actual weight loss occurs as a result of water weight.
Therefore, the weight loss is simply your water rather than actual body fat. In addition, due to such a tremendous calorie restriction, your body is likely to respond quite dramatically and reduce your metabolic rate which can cause weight re-gain.
This means that the diet may help you shed a few pounds in the beginning but the pounds will only pile back on once the diet is completed.
Is it healthy and sustainable?
Each phase of the sirtfood diet is extremely restricting in terms of calories, and despite the foods being nutritious, it’s unlikely to be sustainable. It may be best to simply include sirtfoods within your healthy balanced diet to obtain the health-protective benefits.
Is there an eating plan for the diet?
Yes, yes there is. However, to obtain the meal plan you will need to purchase the ‘The Sirtfood Diet’ book.
In summary, the Sirtfood diet is rich in healthy foods that protect the body against a variety of diseases but it is highly unsustainable due to the low-calorie intake.
Although the sirtfood diet can cause significant weight loss, you are also likely to experience weight regain shortly after. This is commonly caused by metabolic changes. We recommend a simple balanced diet and an appropriate calorie restriction that promotes steady weight loss.
If you do wish to proceed with the diet, then make sure to monitor your weight loss during the two phases to see how your body is responding.
If, after the three weeks, you feel good and you’d like to continue eating this way, then make sure to consume at least one meal that is rich in sirtfoods and one sirtfood green juice.
However, make sure not to perform this diet for excessive periods of time as it might suppress your metabolism and it may hinder further weight loss.
