The Sirtfood Diet has been at the center of a cyclone of controversy since it was first put forward in 2016. It has all the hallmarks of a fad diet: extreme calorie restriction, magical ‘superfoods’ and a reliance on liquified foods for weight loss outcomes. While none of these things are inherently bad, when combined and presented as a ‘miracle weight loss solution’ it can cause unhealthy eating habits.

The diet is focused on increasing your intake of sirtuins, a type of protein that functions as an epigenetic regulator, which have been put forward as possessing anti-aging and anti-disease properties, as well as possibly extending human lifespan. While this all sounds fantastic, does the three-week diet actually have any impact on your health?
