What Is The Sirtfood Diet?

The Sirtfood diet was designed by two celebrity nutritionists, Aidan Goggins and Glen Matten. It focuses on the consumption of foods rich in sirtuins activators, often referred to as ‘sirtfoods.’

Their book, The Sirtfood Diet, claims that following this diet for one week can help people lose about 7 pounds of weight. However, the specific results of their study have not been published anywhere else.

The sirtfoods activate a group of seven proteins in the body called sirtuins (SIRTs) (1), (2). One of the many functions of these SIRTs is the metabolism of fatty acids and cholesterol. This activation has a similar effect on the body as calorie restriction. Sirtfoods are known to support weight loss and improve age-related metabolic diseasesi  Diseases that disrupt normal metabolism - the process of converting food to energy on a cellular level. Examples (2)

Include the following foods in your Sirtfood diet (2),(3) :

  • Arugula (rocket)
  • Cereals (Oats, barley, quinoa)
  • Matcha green tea
  • Blueberries
  • Dark chocolate (85% cocoa)
  • Extra-virgin olive oil
  • Kale
  • Bird’s eye chili
  • Capers
  • Coffee
  • Lovage
  • Medjool dates
  • Onions
  • Turmeric
  • Soy
  • Strawberries
  • Buckwheat
  • Parsley
  • Red chicory
  • Red wine
  • Walnuts

As per a study published in the HHS Author Manuscripts, foods rich in sirtuin-activating, polyphenols such as resveratrol (found in red wine, and red grapes), piceatannol (found in grapes), etc., could one day be used to improve human healthspan (the part of a person’s life when they are good health) (2), (4). However, most of these studies are limited to rat models, and more research is required to test their full effects and the scope of use for human health (5).

How Does The Sirtfood Diet Work?

Weekly phases of sirtfood diet plan

The Sirtfood diet works in two phases lasting up to three weeks. After that, you can go easy on calorie restriction and continue consuming sirtfoods to sustain weight loss.

The two phases are as follows:

  • Phase 1 (Week 1): Calorie Restriction And Sirtfood Green Juices
    For the first three days, keep your calorie intake up to 1,000 calories per day. Eat one meal richly made with sirtfoods and three homemade green drinks made from celery, spinach, or kale.

Increase your calorie intake to 1,500 calories from day four to seven. Consume two sirtfood meals and two green drinks on these days.

  • Phase 2 (Weeks 2-3): Maintenance
    During this period, consume three sirtuin-activating meals and one green drink per day. This phase will help promote steady weight loss. You do not need to strictly manage your calories. However, make sure not to overeat.

After these phases, you may continue “sirtyfying” – eating sirtfood meals. You may also repeat these phases to induce more weight loss.

Pippa Middleton, sister of Kate Middleton, is one of the famous people to have tried the Sirtfood Diet.

Following the Sirtfood diet is more of a lifestyle that can lead to multiple health benefits. However, it may not be suitable for all and may cause side effects if not followed properly. Check out the next section to discover the health benefits and downsides of the Sirtfood diet.

Benefits of the sirt food diet

  • May Protect Against Inflammation

Sirtuin-rich foods are loaded with anti-inflammatory properties. Following the Sirtfood Diet may help to reduce chronic inflammation of the lungs, liver, and kidneys (6).

  • May Have Anti-Aging Benefits

The proteins of the sirtuin family have been shown to slow down the aging process (7). The Sirtfood diet may be used for lifespan extension and promoting healthy aging (8).

  • May Promote Weight Loss

This diet is popularly used to help combat extra body weight. One study published in the journal Frontiers In Immunology sheds light on the possible link between sirtuin activation and weight loss by regulating glucose and lipid metabolism and energy homeostasisi  The balance between energy intake (calories consumed) and energy expenditure (calories burned). (9).

protip_icon Trivia
Exercising activates sirtuins, which may help manage obesity, insulin resistance, and type 2 diabetes. Combine your Sirtfood diet with exercise for maximum therapeutic effects on metabolic health (10).


  • May Reduce Energy Levels

Restricting calories may lead to physiological and psychological problems during the initial phase of that diet. This may lead to fatigue, weakness, dizziness, and hunger pangs.

  • May Lead To Nutrient Deficiency

Sticking to only sirtuin-activating foods or being too restrictive with your food may lead to nutrient deficiencies of various vitamins and minerals. Therefore, it is important to consume other healthy fruits and vegetables after the first week along with the sirtfoods.

  • May Not Be Sustainable

The Sirtfood diet may get boring and repetitive as you have to repeat recipes. This could be one of the reasons why some people may not be able to continue it for another round of 3 weeks. However, remember that the weight loss results may not be sustainable and you may regain weight once you discontinue following the sirtfood diet and resume your regular diet.

You can prevent the possible downsides of the Sirtfood diet by consulting a dietitian and getting a personalized meal plan. For a one-week reference meal plan, check out the plan below.
