What Is The Sirtfood Diet, And Is It Vegan?

by Toni Olukiran

1min read

The sirtfood gets attention for the fact that it includes dark chocolate and red wine into its plan — but what is the diet really, and is it vegan-friendly? Find out everything you need to know about the popular new diet. 

What is the sirtfood diet?

The sirtfood diet was launched in 2016, and the foundation is a low calorie plan that includes specific ‘sirtfoods’. Sirtfoods are foods containing proteins called sirtuins, which are said to activate the metabolism and help the body’s ability to burn fat while maintaining muscle, though this is disputed. 

What are some examples of sirtfoods?

Some common sirtfoods include:

  • Apples
  • Citrus fruits
  • Soy
  • Capers
  • Blueberries
  • Kale
  • Turmeric
  • Green tea
  • Walnuts

Is the sirtfood diet suitable for vegans?

In theory, the diet is vegan friendly as there is no requirement that meat or dairy products are eaten in the meal plans, and the diet emphasises consuming sirtfoods, of which are typically fruit and vegetables. 

Is the sirtfood diet safe?

The sirtfood diet requires participants to restrict their calorie intake to 1000 kcals a day in the first couple of days (made up of one sirtfood meal and three sirtfood juices) and to 1500 kcals a day the following few days (made up of two sirtfood juices and two sirtfood meals). This type of diet is often not sustainable and ultimately you are much likely better off incorporating these healthy foods as part of a balanced diet that is much less restrictive. If you do want to do the sirtfood diet, consult your GP beforehand to see if it is suitable for you.
