Sirtfood Diet: Recipes, 7-Day Diet Plan, And Side Effects
Made by nutritionists, this diet reduces inflammation and increases metabolism to aid weight loss.
The Sirtfood diet aids fast and long-term weight loss by boosting metabolism to burn fat quickly (1). It is not a fad diet, neither does it require you to follow an extreme exercise routine. It was developed by celebrity nutritionists Aidan Goggins and Glen Matten (UK). This diet activates genes that increase metabolism and reduce inflammation through certain foods. These “wonder foods” also help whittle away stubborn belly fat and overall body fat. This article lists the Sirt food diet foods and gives a detailed account of what the Sirtfood diet is. Read on!

What Is the Sirtfood Diet?
The Sirtfood diet is a nutritionally balanced diet comprised of foods that have the ability to turn on the sirtuin (SIRT1) genes. The SIRT1 genes that get activated by these foods increase your body’s metabolic rate, improve your muscle tone, and boost overall health.
The UK nutritionists, Aidan Goggins and Glen Matten were the proponents of the Sirtfood diet. They laid out a plan of drinking three green juices along with balanced Sirtfood meals to kick-start metabolism and lead a healthy, disease-free life.
With the Sirtfood diet, dieters can avoid severe calorie-restricted diets, have more energy, lose fat fast without losing muscle, and do not have to perform grueling exercise routines. The diet is certainly a relief from the other bland and demanding diet plans, like the GM diet. What really happens when you are on the Sirtfood diet? Find out in the next section.
How Does The Sirtfood Diet Work? Is It Effective For Weight Loss?
The Sirtfood diet includes foods that activate the SIRT1 genes. This diet is full of healthy foods that switch the SIRT1 genes on and effectively trigger weight loss at the molecular level. Here’s how the Sirtfood diet works:
- Mobilizes the fat – Scientists have found that the foods included in the Sirtfood diet help morph the stored white adipose tissue to brown fat, which gets readily mobilized and used up as energy (2). This means that the stored fat starts to melt and leads to weight loss.
- Prevents fat accumulation – The SIRT1 genes regulate adipokine expression. Adipokines are secreted by fat cells that affect insulin sensitivity and hunger and increase inflammation. The SIRT1 gene activation through foods included in the Sirtfood diet helps reduce adipokine secretion. This prevents excessive fat accumulation and untimely hunger (3), (4).
- Improves insulin sensitivity – The inability of the cells to respond to insulin (a hormone responsible for uptake of glucose from the bloodstream by cells) leads to increased blood sugar levels, obesity, and Type 2 diabetes. Research shows that activating SIRT1 genes improves insulin sensitivity. This, in turn, improves metabolism, enhances the release of thyroid hormones, burns more fat, and protects against high-fat induced obesity (1), (5), (6).
- Controls excessive hunger – Leptin is a hormone secreted by fat cells to signal the brain of satiety. However, sometimes, leptin resistance may inhibit this signal to the brain. This leads to constant hunger and overeating. Scientists have found that increased SIRT1 levels in laboratory mice prevent age-associated weight gain and increased leptin sensitivity. Improving SIRT1 genes through NAD+ intermediates (crucial for SIRT1 activation) may help control excessive hunger by sensitizing the body to leptin (7).
- Preserves lean muscle – Activated SIRT1 genes help preserve lean muscle mass while burning fat. Sirtuins (proteins produced by the SIRT1 genes) increase skeletal muscle mass (8). The activated SIRT1 genes boost muscle growth and recovery. Therefore, age-associated muscle loss and exercise-induced muscle loss can be prevented.
- Reduces inflammation – Constant state of low-grade inflammation can cause cells to function abnormally. This leads to fat accumulation and obesity-related comorbidities (like diabetes and heart disease) (1). Activated SIRT1 genes help reduce inflammation and reduce the risk of heart disease, tumors, and Alzheimer’s disease (9).
Now that we know how well the Sirtfood diet can work for weight loss, let us discuss the foods that help activate the SIRT1 genes.
What Are “Sirtfoods”?
Sirtfoods are the foods that activate the SIRT1 genes. Sirtfoods are mainly plant-based foods that contain powerful phytonutrients (plant nutrients). These activate the sirtuin-activating biochemicals, which otherwise only get activated in response to stress like fasting or exercising.
When you consume these Sirtfoods, your body mimics the stress response without you having to actually fast or exercise. Hence, you burn calories/fat without losing muscle mass, without fasting, and without doing vigorous exercises (10). In the following section, we will take a quick look at the foods you can eat on the Sirtfood diet.
What Can You Eat On The Sirtfood Diet?
There are 20 SIRT1 activating foods you can include in your diet to lose weight, get rid of stubborn belly fat, and restore muscle mass. Take a look at the table below:

What Can’t You Eat?
Avoid the following foods while on the Sirtfood diet:
- Processed foods – Salami, sausage, frozen foods, ready-to-eat foods, and packed fruit juices.
- Sugary foods – Candies, cakes, soda, packaged fruit juice, doughnuts, pastries, marshmallows, coffee or tea with cream and sugar, refined sugar, etc.
- Fats and Oils – Butter, lard, and vegetable oil.
- Starch – White rice and potato.
- Trans Fats – Fries, burger, pizza, fried chicken, chips, and biscuits.
The Sirtfood diet is a fairly simple diet to follow. It is divided into two phases, and each phase lasts for a week. Here’s a sample diet chart for Phase 1 that you can repeat for Phase 2 as well. Take a look.
7 Day Sirtfood Diet Plan – Phase 1 And Phase 2
Phase 1: Week 1
Phase 1 of the Sirtfood diet continues in two stages – Stage 1 and Stage 2, each lasting for 3 and 4 days, respectively. Here’s what to eat in the first stage of Phase 1.
Stage 1 (Day 1 – Day 3)
(1000 calories per day)
- 3 green juices per day
- 1 main meal per day
- ½ or ¾ ounce of 85% dark chocolate
Main Meal Options
- Red edamame, tomato, arugula, and buckwheat salad with olive oil dressing
- Celery, kale, and capers salad with walnuts and olive oil
- Chicken breast with arugula, kale, and walnuts with strawberry and olive oil dressing
Stage 2 (Day 4 – Day 7)
(1500 calories per day)
- 2 green juices per day
- 2 main meals per day
Main Meal Options
- Chicken stew
- Sirt museli
- Buckwheat noodles with soy chunks
- Strawberry, arugula, and walnut salad
- Grilled fish with red wine
- Waldorf salad
Phase 2: Week 2
During the second week, you must repeat what you did in the first week and maintain the weight loss.
After Phase 2
After completing 14 days of the Sirtfood diet, here’s what your diet plan should look like:
- 3 balanced Sirtfood-rich meals per day
- 1 Sirtfood green juice per day
- 1 or two Sirtfood snacks per day
Are Sirtfoods The New Superfoods?
Yes, Sirtfoods are the new superfoods. These activate the fat-burning group of genes, SIRT1, and help improve health. These are mainly comprised of plant-based foods. They contain powerful phytonutrients that boost metabolism, prevent muscle loss, and reverse many obesity-related health issues.
Is The Sirtfood Diet Good For You?
Do note that no diet is ideal for all. Consult your nutritionist before starting any new diet. That said, research shows that foods included in the Sirtfood diet, like green tea, turmeric, and dark chocolate, have anti-inflammatory and antioxidant properties. These foods help fight obesity, heart disease, high blood pressure, and stroke (11), (12), (13), (14).
Studies conducted on laboratory animals showed that sirtuin-activating foods increase longevity, improve insulin sensitivity, burn more fat, and lower the risk of cancer (15), (4), (16), (9). Such promising results on lab animals and cell lines may not always mean that the foods can also work well in humans. However, the Sirtfood diet is a well-balanced diet plan that has great potential in aiding fast weight loss in humans.
Safety And Side Effects
To ensure safety, you must talk to your doctor or a registered dietitian before you start this diet. Your age, sex, BMI, medical history, current medication, and lifestyle will help a licensed professional understand whether the Sirtfood diet will suit you. Remember, a diet plan may not always suit all.
If you are new to drinking green juice, you may feel nauseous. Having only one or two solid meals per day with 1000-1500 calories may also make you irritable, hungry, and cranky. Though the diet has its own benefits, it is not meant for everyone.
