Lose 7 pounds in 7 days – that’s what the two Sirtfood developers and nutritionists Aidan Goggins and Glen Metten promise. Adele’s incredible transformation suggest that it works – the Sirtfood diet has been credited for her amazing weight loss.
But what exactly is behind the diet trend that celebrities swear by?
Here you can find out all you need to know about Sirtfood, including which foods are real ‘sirt foods’.
The Sirtfood principle: healthy weight loss with protein
Similar to the ‘low carb’ diet, the Sirtfood diet relies primarily on proteins. More specifically, on a very specific protein called sirtuin (SIRTS), hence the name.
The theory is that basing your diet around this key protein should help the pounds drop quickly and, incidentally, also strengthen the immune system.
Book tip: If you want to try the Sirtfood Diet, we recommend the original book: ‘The Sirt Food Diet’. This includes sirt food lists and Sirtfood diet recipes.
The Sirt Food Diet is available at Amazon. See more details here.
What is Sirtuin?
Sirtuins are a very specific group of proteins, which are considered to help build muscle and burn fat. They’re found naturally in the body, but the founders of the Sirtfood diet claim that eating certain foods can increase the level of these proteins in your body.
Many also refer to the sirtuin proteins as ‘super proteins’. This is because sirtuins are thought to do more than just help you lose weight: some people suggest that they also strengthen the immune system and help to protect the body from diseases and inflammation.
Some even claim that they can help reduce stress, prevent cravings and slow down the ageing process – though there’s little evidence for this.
How the Sirtfood Diet works: the 3 phases
So should you just eat foods that are high in protein? The Sirtfood Diet is a bit more complicated than that. The diet is not just about what you eat, but also how much, and when.
The Sirtfood Diet is based on three phases
In the first phase (day 1 to day 3), only 1000 kcal are consumed daily in the form of three green juices and a main meal. Of course, only foods that contain a lot of sirtuin end up on the plate. The juices are made from sirt foods such as rocket leaves, celery, parsley and apples.
In the second phase (day 4 to day 7), the calorie intake is increased to 1500 calories. There are two green juices and two main meals a day. This phase is carried out until the desired weight is reached.
The third and final phase of the Sirtfood Diet serves to stabilise the new weight – about 1800 kcal are consumed daily. Of course, many sirt foods are still on the menu here, but other foods are slowly being taken up again to get the body used to it again.
Important: The third phase can be carried out as long as you like, depending on your taste, though it’s often done for 14 days. In the long term, you should definitely take care not to fall into old eating patterns, and instead to rely on healthy foods and lots of protein.
What can I eat on the Sirtfood Diet?
Unfortunately, there aren’t that many foods that are rich in sirtuin. However, you can be happy, because chocolate and red wine are on the list of sirt foods. Yes, you heard that right!
The downer: the chocolate must have a cocoa content of at least 85%. Sorry, milk and white chocolate fans!
And even if red wine contains sirtuin, you should only enjoy it in moderation. Because not only is there a lot of sugar in it, too much alcohol can also lead to weight gain.
So stick to the government’s recommended limits of no more than 14 units per week.
Sirt food list:
- buckwheat (available here at Amazon)
- green tea
- rocket (arugula)
- cold-pressed olive oil
- red onions
- black coffee
- red wine
- dark chocolate (at least 85% cocoa content)
- chicken and poultry
- red meat (up to three times a week)

Does the Sirtfood diet really work?
The Sirtfood diet is pretty radical, especially in the first days, since you can only consume very few calories, just 1000kcal every day (vs the recommended 2,000 calories for women or 2,500 for men).
In addition, what is supposed to land on the plate is limited. In the first phase, the diet has a relatively high potential for frustration. Afterwards, the daily calorie intake is limited to 1500 or in the third phase to 1800 calories.
It is a positive that the Sirtfood method focuses on fresh and healthy food. For example, there are a lot of green vegetables on the menu.
Nevertheless, the Sirtfood method, like other diets, remains relatively limited and daily calorie counting is mandatory. This might not make it sustainable long term.
The authors of the diet make great weight loss claims, and some celebs have reportedly had success with it, including Adele who posted this picture of her slim self on her Insta page.
However, scientific studies suggest that the Sirtfood diet is no better for weight loss than any other calorie-controlled diet. You’ll lose weight, but it’s because you’re cutting down on calories, not because of the specific foods you’re eating.
If you want to lose weight in a healthy and permanent way, we recommend changing your diet over the long term and eating a healthy and balanced diet. Losing weight takes a little longer, but is more sustainable in the long run.
Can I do the Sirtfood Diet if I’m pregnant or TTC?
If you are pregnant, it is not advisable to take up any strict diet. This could damage the health of your unborn baby, who needs healthy, nutritious and balanced foods from your diet.
If you are overweight and trying to conceive, you could try the diet short term to help with weight loss, though be mindful not to lose too much weight, as this can have an adverse affect on your health too.
Always speak to your GP before embarking on a new diet if you’re trying to get pregnant.
