This diet is rich in sirtuins, proteins found in your body that regulate lifespan, boost metabolism and reduce inflammation. By increasing metabolism, your body starts to lose fat faster. This diet includes plant-based foods that contain polyphenols, which mimic the effects of fasting and exercise.

How to Do It

Sirtfood diet consists of two phases:

  1. It lasts one week and you have to restrict your calorie intake to 1000kcal/day the first three days. You just need to consume three green juices and one sirtfood-rich meal each day. On days four to seven your calorie intake is 1500kcal/day: two green juices and two sirtfood-rich meals each day. 
  2. The next phase lasts 14 days without caloric restriction. Just eat three full meals of sirtfoods and one sirtfood green juice per day.

Once you finish, you can start the cycle again depending on your weight loss goal. 

Some examples of sirtfoods are green tea, dark chocolate (85%), apples, citrus fruits, parsley, turmeric and kale.

Why it works

  • Sirtuin-rich foods increase metabolism and fat loss, without compromising muscle mass. 
  • Caloric restriction is a common element, proven to be essential when it comes to lose weight. 
  • The polyphenols present in sirtuin-rich foods promote healthy aging, cardiac health, and overall health in the long term.
