What are Sirtfoods?
‘Sirtfoods’ is a term applied to foods that contain naturally occurring compounds known as polyphenols that have the potential to activate sirtuins.
‘Sirt’ is a short term of sirtuin. Sirtuin is a class of proteins in the body that are important for regulating biological pathways that can affect our weight and health.
Dr. Kushal Banerjee from Harvard Medical School says ‘Foods don’t contain sirtuins, but they contain compounds that activate sirtuins.’
What are sirtuins?
Sirtuins first came to light in a study in 2003 when researchers found that resveratrol – compound found in red wine and red grape skin, dramatically increased the life span of yeast.
After this discovery, it was found that resveratrol had the same effect on longevity as calorie restriction. And the good thing is that this effect can be achieved without reducing energy intake.
Since this discovery, many studies were made first on worms, flies, fishes, after that on mice and humans, and these studies showed that resveratrol protects against the adverse effects of high-fat, high-calorie, and high-sugar diets.
At the same time promotes healthy aging by delaying age-related diseases and it has been shown to mimic the effects of calorie restriction and exercise.
As a result of all of this red wine with its rich content of resveratrol was hailed as the original Sirtfood. We can say that this is the beginning of the Sirtfood story.
Now there is a question why are sirtuins so important and how they help with weight loss?
You probably reading this article about Sirtfoods because you’ve heard about Sirtfood Diet that helped Adele to lose weight.
Well, these proteins in the past 10 years have been the subject to anti-aging researchers, until now. There are seven identified sirtuins: SIRT1, SIRT2, SIRT3, SIRT4, SIRT5, SIRT6, and SIRT7.
Researches investigate specific roles of sirtuins such as the implication of SIRT3 on cardiovascular disease, the impact of SIRT6 on the stress response. Clinical evidence demonstrates the impact of sirtuins on oxidative stress mechanism, glucose metabolism, caloric restriction process, and fat loss.
Until now studies suggest that only SIRT4 may be the only one of sirtuins that have no role in oxidative stress. From all seven SIRT1 is the one that we know most about.
Why is SIRT1 important when it comes to weight loss?
We all know that if we want to lose weight we must restrict our calorie intake, fewer calories equal falling pounds, right?
But in that process or mechanism of losing weight sirtuins are an important factor. When ‘switched on’ by exercise or calorie restriction the result is fat loss.
Banerjee explains this so simple – ‘When you restrict calories, SIRT1 is activated and tells your body to switch from glucose as an energy source to breaking down fat and using that, rather than storing it’.
He also add to this ‘ SIRT1 speeds up the metabolic rate and therefore the rate at which your food is burnt.’
Following the Sirt Diet and eating sirtfood-rich meals encourages SIRT1 activation. This ignites the body’s natural properties of burning fat and warding off disease.
