The ins and outs of diet that helped Adele lose 40kgs

The basis of the Sirtfood diet is to activate molecules called sirtuins, which are naturally present in your body.

Activated sirtuins can help slow down aging while helping with regulating weight (1).

What are sirtuins?

Sirtuins (aka silent information regulator 2 family) are molecules necessary for metabolism. They also protect your body from stress.

When on a calorie restriction diet, sirtuins help prolong your lifespan. They’re activated when energy in the body is low—through stress or calorie restriction.

At this point only the most basic cellular functions are still running, which helps cells live longer (2, 3). Sirtuin works by interacting with insulin and molecules activated by insulin (1, 5-7).

Sirtuins also help reduce white fat mass and through that they slow down how your body ages (8).

Sirtuin activating compounds (STACs)

There are a number of foods that can activate sirtuins in your body, although the adequate concentration needed to activate sirtuins in humans is still unknown (1).

These natural molecules are considered to be sirtuin activators:

  • Resveratrol
    Found in raspberries, blueberries, peanuts, and red grape skins—helps fight inflammation and improve heart health (9)

  • Piceatannol
    Found in red wine and white tea—it’s used as herbal medicine in Asia (10)

  • Fisetin
    Found in strawberries—can help enhancing long-term memory (11)

  • Quercetin
    Found in capers, apples, tea, onion, kale, citrus fruit, and berries—helps fight inflammation (12)

  • Polyphenols
    Found in curcumin and turmeric—effect depends on concentrations (in low doses it’s beneficial, in high doses it might be harmful (13, 14)

  • Melatonin (15)

  • Oligonol
    Found mostly in lychees—contains anti-inflammatory properties (16)

  • Omega-3 
    Found in flaxseed and fish—some research suggests it might be helpful in boosting sirtuin levels in the blood (17)

These natural compounds can help improve insulin sensitivity and lower blood sugar levels (18).

Exercise is also beneficial for sirtuin activation. Long-term moderate exercise has been shown to increase sirtuin levels in muscles (19).

Sirtuin blockers

Nicotinamide is a form of vitamin B3. It’s found in a lot of food including meat, poultry, tuna, salmon, cereals, legumes, and seeds. and it’s used as a dietary supplement.

Although nicotinamide is beneficial for brain functioning and metabolism, it can block the activity of some sirtuins (20).

Sirtuins and thyroid health

Sirtuins are involved in thyroid activity. They help enhance the activation of the T3 hormone in the liver (21).

Sirtuins can also help to reduce the risk of developing an autoimmune disease. They can also help with managing flare-ups (22).
