Where does Sirtfood come from?
A diet centered on foods (kale, green tea, dark chocolate, red wine) said to activate sirtuin genes, with a steep low-calorie start. Early weight loss is mostly water and calorie restriction; the sirtuin claims are unproven.

Who is Sirtfood for?
The goals this pattern is most often used for. In a consult we confirm whether it actually fits your body and life.
Is there good evidence that Sirtfood works?
Nidari rates the evidence behind Sirtfood’s primary claims as limited / unproven — that is the current weight of peer-reviewed research for those claims, and nothing more. This one is included for completeness — the evidence does not strongly support its specific claims, and we’ll always tell you so.
How does Nidari adapt Sirtfood?
The “magic foods” framing oversells it — but kale, turmeric and berries are great. We use them without the gimmick or the crash-calorie start.
