Founders Aidan Goggins and Glen Matten created the eating regimen in 2016 after noticing that the potential advantages of polyphenol-rich crops have been being studied within the context of medication, however not vitamin, and that among the world’s healthiest populations ate extra plant meals.
Because of this, the pair recognized probably the most polyphenol-rich meals and aimed to seek out out whether or not consuming extra of them would provide related advantages.

- further virgin olive oil
- inexperienced tea (particularly matcha)
- kale
- lovage
- Medjool dates
- parsley
- crimson chicory

What are the Limitations?
These really helpful meals—together with chocolate, crimson wine, and low—are usually wholesome sparsely. Nevertheless, there nonetheless is not sufficient analysis on polyphenol’s impact on people to again up the declare that sticking to those meals can “supercharge weight reduction and stave off illness.”
“There’s nothing magical about having these parts from the meals that is going to make you drop some pounds,” Lisa Younger, RDN, Ph.D., professor of vitamin at NYU and creator of Lastly Full, Lastly Slim, tells Eat This, Not That!. “There isn’t any analysis to show that in people, in order that’s extra like wishful considering.”
The opposite primary side of the eating regimen is calorie restriction, notably within the first week. It prescribes only one sirtfood-rich meal, plus three glasses of sirtfood inexperienced juice, on every of the primary three days. That is 1,000 energy or much less every day.
Younger cautions in opposition to consuming lower than 1,200 energy per day and finds one stable meal per day to be too restrictive. “I do not assume if you happen to do it for just a few days, it is harmful per se, but it surely’s actually not a wholesome method to drop some pounds,” Younger cautions, including that the 7-pound weight reduction in seven days that the eating regimen ensures can be largely water weight.
Days 4 by way of seven on the plan name for 2 inexperienced juices and two meals per day, limiting energy to 1,500. This, in addition to the remainder of the three-week plan (which calls for 3 balanced meals a day and the inclusion of sirtfood juice), is cheap so far as Younger can see.
What is the remaining verdict?
The Sirtfood Food regimen is not essentially unhealthy, aside from the intense calorie restriction and fast weight reduction through the first few days—each of which aren’t sustainable, Younger says. The eating regimen’s greatest downfall, although, could also be the advantages it advertises, which have not been verified by analysis.
On the whole, consuming extra nutritious meals like these the eating regimen suggests is not a nasty thought. “Take pleasure in these meals—not as a result of there’s magic to them, however as a result of they’re wholesome meals,” Younger says.
