Intermittent fasting has evolved from an ancient practice to one of the most scientifically validated strategies for improving nutrient sensitivity, restoring metabolic efficiency, and slowing aging . Unlike traditional restrictive diets, it focuses not on what you eat, but when you eat , allowing the body to enter natural physiological phases of repair, purification, and energy efficiency.
Over time, our bodies lose metabolic flexibility: they no longer respond as effectively to insulin, leptin, or mTOR signals , and cells accumulate damage due to the lack of metabolic rest periods. This is where intermittent fasting emerges as a restorative tool.
What is intermittent fasting and how does it work?
Intermittent fasting (IF) involves alternating periods of eating with periods of fasting or energy restriction. The most common protocols are:
-
16:8 (16 hours fasting, 8 hours feeding window).
-
14:10 (softer and more sustainable for beginners).
-
24 hours 1–2 times per week (in more advanced approaches).
During fasting hours, insulin levels decrease, which:
-
Promotes the oxidation of fats .
-
Reduces inflammation.
-
Stimulates autophagy (cellular recycling).
-
Activates AMPK and modulates mTOR , promoting repair processes instead of accumulation.
Benefits of intermittent fasting in nutrient detection
-
Improves insulin and leptin sensitivity .
-
Reduces oxidative stress by decreasing caloric overload and the production of free radicals.
-
It resets metabolic sensors , allowing the body to regain its ability to distinguish when it needs energy and when it doesn't.
-
Reduces chronic inflammation , key to cellular sensor dysfunction.
-
It promotes mitochondrial biogenesis , improving cellular energy efficiency.
Intermittent fasting and healthy aging
Studies in humans and animal models have shown that AI:
-
Reduces the risk of metabolic diseases such as type 2 diabetes.
-
Improves cognitive function.
-
Promotes longevity by modulating genes related to aging.
These improvements are achieved not only by restricting energy, but also by reorganizing metabolic cycles : by giving the body periods without digestion, we force it to "look inward" and clean out accumulated waste.
Support from Sevens to accompany the fast
Fasting can be complemented with supplementation that promotes autophagy, energy stability and reduction of oxidative stress :
-
Magnesium Sevens : ideal for maintaining muscle and nerve function during fasting, and to prevent drops in energy levels.
-
BIO Sevens Turmeric : Strengthens autophagy and reduces inflammation, amplifying the restorative benefits of fasting.
-
Omega 3 Sevens : helps modulate the inflammatory response and stabilizes blood lipids, which may increase slightly during adaptation phases.
These products help the body more efficiently enter and maintain a state of metabolic repair without interfering with fasting.
Conclusion
Intermittent fasting is not a fad, but an evolutionary tool that the body recognizes as part of its natural design . Applied judiciously and accompanied by conscious nutrition and the strategic support of supplements like those from Sevens, it can restore nutrient sensitivity, rejuvenate cells, and profoundly improve metabolic quality. It's not about starving yourself, but about giving your body the time it needs to repair and reorganize .
