In recent years, the Sirtfood Diet has captured widespread attention, particularly after being associated with Adele’s dramatic weight transformation. But beyond the celebrity endorsements lies a fascinating nutritional approach based on activating specific proteins in our bodies called sirtuins.
What Is the Sirtfood Diet?
The Sirtfood Diet, developed by nutritionists Aidan Goggins and Glen Matten, focuses on foods rich in compounds that activate sirtuins—proteins that regulate various biological processes in the body. These proteins, often called “skinny genes,” play crucial roles in metabolism, aging, and cellular health.
The Science Behind Sirtfoods
Sirtuins are a family of proteins that act as the body’s natural defense and repair mechanisms. When activated, they can help:
- Boost metabolic efficiency
- Reduce inflammation
- Protect cells from oxidative stress
- Regulate the body’s circadian rhythms
- Influence fat storage and burning
How Does the Diet Work?
The Sirtfood Diet is structured in two distinct phases:
Phase One (7 Days)
Days 1-3:
- Restrict calories to 1,000 calories per day
- Consume three green juices daily
- One Sirtfood-rich meal
Days 4-7:
- Increase to 1,500 calories daily
- Two green juices
- Two Sirtfood-rich meals
Phase Two (14 Days)
- Maintenance phase
- Three Sirtfood-rich meals daily
- One green juice
- No calorie restriction
Key Sirtfoods to Include
The diet emphasizes consuming these Sirtuin-activating foods:
- Dark chocolate (85% cocoa or higher)
- Red wine (particularly rich in resveratrol)
- Citrus fruits
- Kale
- Strawberries
- Walnuts
- Extra virgin olive oil
- Green tea
- Turmeric
- Red onions
- Parsley
- Buckwheat
- Coffee
- Matcha green tea
Benefits of the Sirtfood Diet
Weight Loss Potential
The combination of calorie restriction and sirtuin activation can lead to significant weight loss, particularly during the first phase. Many followers report losing 7-14 pounds in the first two weeks.
Cellular Health
Sirtfoods are rich in polyphenols, which can help:
- Protect cells from damage
- Reduce inflammation
- Support healthy aging
- Improve energy levels
Sustainable Eating
Unlike many restrictive diets, the Sirtfood approach includes a variety of delicious foods and even allows for red wine and dark chocolate in moderation.

Success with this diet requires commitment, planning, and a willingness to embrace new foods and preparation methods. For those who can navigate the initial challenges, the Sirtfood Diet may offer a path to improved health and sustainable weight management.
