The Sirtfood Diet is a weight loss program that focuses on eating foods rich in sirtuin activators, also referred to as SIRTs, that help facilitate weight loss through activation of the metabolism. Foods that are high in sirtuin activators include coffee, green tea, dark chocolate, blueberries, and turmeric.
According to Goggins and Matten, eating these foods will activate the “skinny genes” to facilitate weight loss. Also, consuming foods that are high in these sirtuin activators will also help with inflammation and overall healthy aging.
Created by nutritionist Aidan Goggins and Glen Matten, the diet has become popular in recent years.In 2020, the diet became an international sensation when its creators claimed that Adele’s outstanding 100-pound weight loss was thanks to her following the SIRTfood diet. Pippa Middleton is also rumored to follow the SIRTfood diet to maintain her excellent physique.
How Does Sirtfood Diet Work?
The SIRTfood diet centers around foods that elicit high sirtuins (SIRTs) response, a family of signal proteins involved in regulating metabolism. Foods like kale, red wine, and turmeric, which are high in polyphenols, mimic the effect of exercise and fasting within the body. In response, sirtuin proteins are triggered, which regulates inflammation, metabolism, and aging.
The SIRTfood diet focuses on calorie restriction and consumption of high amounts of SIRT foods. The creators of this diet claim that the SIRTfood diet can wake up the “skinny genes” to help dieters lose 7 pounds in seven days. This diet consists of two phases. Participants are expected to consume a specific green juice and SIRT food meal as directed by their phase.
What Are the Phases of the Sirtfood Diet?
The first phase of the SIRT food diet lasts for seven days and can be broken into two half-phases. In the first three days of phase 1, participants must consume three servings of a specific SIRTfood green juice and one SIRTfood meal, totaling 1000 calories daily. Later on, dieters cut down the green juice to two servings a day on days four through seven and have two SIRT-rich meals totaling 1500 calories a day.
The second phase of the SIRTfood diet consists of a 14-day maintenance program. During this time, dieters must eat three balanced SIRT meals daily and one green juice. Although this is the maintenance phase, dieters are still expected to lose weight. After the maintenance phase, dieters are still expected to continue drinking one serving of SIRT green juice daily and consume a diet high in SIRTs.

- Do the Second Part of Phase 1 of the Sirtfood Diet (Days 4-7): In the second part of phase 1, dieters will cut down the green juices to two servings a day and bump dieters meals to two meals a day.
- Start Phase 2 of the Sirtfood Diet (Days 8 – 21): The remaining 14 days on the Sirtfood diet are considered the maintenance phase. This is where dieters are expected to eat 3 SIRT meals a day, along with one serving of green juice.
- Continue the Sirtfood Diet Until Desired Weight Loss is Reached Loss: After dieters have completed one cycle of the Sirtfood diet, continue cycling through the two phases of the Sirtfood diet until dieters have reached dieters weight loss goals.
