What Foods Can You Eat on the SirtFood Diet

The Sirt Food is very popular and not without good reason. It is arguably one of the most healthiest diets you can start – it is not just focused on weight loss but life longevity as well.

What Foods Can You Eat on the SirtFood Diet

Thanks to associations with British celebrities such as Adele and Lorraine Pascale, the SirtFood Diet has become one of the trendier ways to lose weight.

The SirtFood Diet was developed by a couple of celebrity nutritionists from a private gym in the UK. It forces you to stick to a very restricted diet that allegedly helps you to lose weight and avoid disease.

The diet aims to trigger a group of seven proteins called sirtuins (SIRTs) that appear to regulate several biological functions including metabolism and lifespan.

However, the diet only permits 1,000 calories per day. The average woman requires 2,000 calories per day just to maintain life. The average man needs 500 calories more. It doesn’t matter what diet plan you follow, with a drastic calorie reduction like that, there is no way you couldn’t lose weight.

Such an intense calorie restriction makes the SirtFood Diet a crash diet. As you may be aware, crash diets are frowned upon by many medical and nutritional experts. 

The American CDC and similar advisory bodies suggest a safe weight loss of no more than one to two pounds per week.

The participants in one SirtFood Diet study lost seven pounds per week (on average).

This article is not an introduction to the SirtFood Diet, though. Nor is it a critical essay or an article about the various pros and cons. It’s for people who are already familiar with the SirtFood Diet and want to learn more about the foods it permits.

In addition to listing some of the most popular sirtfoods, it also provides information about their nutritional value. 

17 Foods You Can Eat on the SirtFood Diet

1. Apples

Although this food caused trouble in paradise, as far as the SirtFood Diet goes, apples are not a forbidden fruit. That’s good because they provide several valuable nutrients including Vitamins C and K.

Apples are also an excellent source of dietary fiber, so they help keep your stomach full. They work as a natural appetite suppressant.

2. Citrus Fruit

A good source of SIRTs, citrus fruits are generally associated with Vitamin C. However, they provide a multitude of additional nutrients as well and, of course, plenty of dietary fiber.

Citrus fruits are also good for your heart. The results of a study published in the Journal of Epidemiology show people who ate more citrus had lower rates of heart disease and stroke. (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3899405/)

3. Soy

Soybeans are high in protein and also provide decent amounts of carbohydrates and fat. In addition to being acceptable as a sirtfood, they are also one of the best protein sources for vegans.

The isoflavones in soy may help reduce the symptoms of menopause. Several studies suggest this potential. However, some research suggests soy may affect fertility, so it’s quite a controversial food.

4. Buckwheat

Buckwheat is a nutritious grain-like seed you can use as a replacement for potatoes, rice, or couscous. There are many ways to use it. You may be surprised at the number of options if you search for buckwheat recipes online.

Diets that provide buckwheat may offer protection against high cholesterol. Making buckwheat a key part of your SirtDiet meal plan also has the potential to help reduce hunger. That’s very helpful when you are only consuming 1,000 calories per day.

5. Walnuts

Walnuts are an excellent source of magnesium and Vitamin B6. They also provide more Omega-3 than any other nut.

Kind to the heart and good for the gut, walnuts also boost levels of probiotic bacteria. However, you need to tread carefully with this SirtFood. Don’t go nuts. Walnuts are around 65 percent fat. They are great if you suffer from IBS.

6. Garlic

Although garlic is highly nutritious, let’s be realistic. When it comes to this particular root vegetable, the main virtue you are likely to be looking at is the flavor. Garlic is not a food you will be using as a stomach filler.

However, garlic provides allicin. It’s the compound that appears to make garlic so good for reducing high blood pressure. (https://pubmed.ncbi.nlm.nih.gov/24035939/)

7. Dark chocolate

Dark chocolate as an accepted food in a diet! How rare is that? It’s just another one of the things that makes the SirtFood diet so different from most of the other fad diets doing the rounds.

However, although dark chocolate is acceptable because it provides SIRTs, you need to be thinking by the block instead of the bar. At 604 calories per 101-gram bar (70–85 percent cocoa solids), one bar of chocolate would account for around 60 percent of the calories the SirtFood Diet allows for each day.

8. Medjool Dates

Dates are a dead cert if you have a sweet tooth. They are more than 60 percent sugar and a great option if you are looking for a quick snack.

If your energy levels are low, Medjool dates can help but, with so many calories packed into each small portion, you need to treat this sirtfood with respect.

9. Parsley

Parsley is another sirtfood that’s better for providing flavor than filling the stomach. However, parsley is more than just a seasoning. It’s also rich in vitamins A, C, and K and so low in calories that, even if you season heavily, you will barely put a dent in your calorie allocation for the day.

10. Capers

Although they are only small, when it comes to flavor, capers pack a powerful punch. They have a low calorie content too. This makes a small portion of capers a great option for a tasty snack.

An ounce of capers provides around 9 percent of the RDA for Vitamin K, which is necessary for efficient blood clotting and wound healing.

11. Blueberries

Blueberries are one of the most nutritious and antioxidant-rich fruits in the world. They are heart-healthy, brain-boosting, and immune system-enhancing.

Although a handful of blueberries is great for a sweet snack, these little blue balls of goodness are surprisingly low in calories. They provide just 85 calories per cup.

12. Strawberries

Believe it or not, strawberries are often 91 percent water. They are also surprisingly low in carbs so there are only around 32 calories per 100 grams. However, each 100 g serving of strawberries will provide you with 97 percent of the RDA for Vitamin C.

Strawberries as also packed with antioxidants and other plant compounds that promote good health.

13. Turmeric

Known as “the golden spice”, turmeric adds extra flavor and color to meals. As well as being a sirtfood, turmeric may be a brain food as well. It also has an anti-inflammatory effect.

The health benefits of turmeric are due to curcumin. It’s a powerful antioxidant that helps purge the body of free radical toxins that can cause disease.

14. Olive Oil

In America and Britain, olive oil is generally used as a healthy alternative to saturated fats. However, the people living in Mediterranean countries often drizzle olive oil over their food. They even take it on bread.

Olive oil has a reputation for being a heart-friendly food. It’s also good for reducing inflammation and even appears to help prevent diabetes. It’s a good complement for many of the other foods permitted by the SirtFood Diet.

15. Red Onion

Somewhat sweeter-tasting than other types of onions, red onions are very versatile and may work particularly well in a sirt-providing salad.

Red onions get their color from plant pigments called anthocyanins. Numerous studies show people who consume these pigments have a reduced risk of heart disease.

Red onions also boast antibacterial properties and are rich in prebiotic fiber. This type of fiber feeds probiotic bacteria, helping it to multiply and bring about a healthier gut.

16. Rocket

Also known as arugula, rocket is a popular leafy green with a distinctive peppery taste. It’s high in fiber and provides several micronutrients including calcium, folate, potassium, and Vitamin C.

You can use rocket as a replacement for most types of lettuce and, like red onions, it’s a great option for high-sirt salads.

17. Kale

Kale is one of the most nutrient-dense foods on the planet. Its crinkly appearance helps it to stand out from most other types of cabbage. It’s easy to grow and cheap to buy.

Kale is also extremely low in calories so, whether you are following the SirtFood Diet or a less hardcore low-calorie diet, kale is a good food to choose.

3 SirtFood Drinks Options for a Liquid Lunch

The SirtFood Diet also allows green tea, coffee, and red wine.

Green tea is rich in health-enhancing antioxidants and is widely regarded as the healthiest beverage in the world. Drinking green tea can also boost metabolism, making it easier to lose weight but, when you are following the SirtFood Diet, you are unlikely to require additional help.

Coffee boosts metabolism as well. It’s also a stimulant that can deliver a significant energy boost. When you are following the SirtFood Diet and only getting 1,000 calories per day, there’s a good chance you will experience fatigue. Coffee could help you to get through the day. 

Unfortunately, if you have a problem tolerating stimulants, coffee won’t be an option that’s open to you.

When you are following the SirtFood Diet, you can drink the occasional glass of red wine as a treat. However, although the diet permits it, you need to remember red wine provides around 125 calories per glass (5 fl oz).
