Experts have long been investigating sirtuins: what they are and why they are important. Sirtuins are classes of proteins naturally released within our bodies and play a primary role in regulating metabolic functions as well as cellular aging processes. When the level of insulin in the blood increases, a resistance mechanism is triggered, which can cause tissue inflammation. This should not be underestimated, as it may be at the origin of many cancerous or degenerative diseases. Another important aspect in understanding what sirtuins are is this: with aging, these proteins act like sentinels that must activate and remain on alert more frequently. As time goes on, the damage caused by unhealthy foods, altered lifestyles, and bad habits increases.
Sirtuins: What They Are and Why They Help with Weight Loss
If one asks what sirtuins are, it is important to know that they are classes of proteins that regulate metabolic processes linked to insulin resistance and exert a protective action against cancer-related diseases. Why are sirtuins said to help with weight loss? This protein group acts directly on insulin resistance, the process that is activated when we consume foods containing sugars or refined carbohydrates. In situations of stress and caloric restriction, sirtuins come into play and act on several levels:
- enhancing resistance to oxidative stress;
- making metabolism more efficient;
- stimulating cellular regeneration.
This is why they are also known as the proteins of longevity.
What Are Sirtuins and What Are They For
Once we understand what sirtuins are, we can look at how they work. These substances are activated in fasting conditions, when the body enters an “energy-saving mode” and starts drawing from fat reserves. In this way, our body burns excess fat and activates the so-called “slim gene,” targeting fat mass reduction. Starting as early as age 30–35, the body’s natural ability to produce sirtuins decreases. Around this age, metabolism begins to change, working more slowly and less efficiently. We have seen what sirtuins are for in relation to metabolism and longevity: they counteract the process of cellular aging and instead promote renewal. But how can we introduce them into our bodies to strengthen natural production? Nutrition plays an important role, along with the intake of high-quality specific supplements such as SIRTLIFE products.
The Sirt Diet: Where Are Sirtuins Found?
There are many foods rich in sirtuins that are recommended within the so-called “Sirt Diet,” a diet based on foods that activate sirtuins. Many of the foods that stimulate the production of these proteins are of plant origin. For example:
- citrus fruits
- blueberries
- capers
- soy
- celery
- arugula
- parsley
- red onion
- red chicory
- nuts
- chocolate
- green tea
- red wine
However, understanding how to activate sirtuins is not only a matter of healthy and mindful eating. It is also necessary to engage in regular physical activity and take supplements that boost metabolism.
