Intermittent fasting is a dietary pattern that alternates between periods of eating and voluntary fasting, and it's been gaining attention for a range of potential health benefits. These may include weight regulation, improved metabolic markers, enhanced cognitive clarity, and even support for cellular repair and longevity.
In short, the more time that your body is not using energy for digesting, the more of your energy is diverted to rest and repair. While research is ongoing, the early findings are promising and have sparked my own curiosity to explore how timing meals might influence overall well-being.
As with anything related to health, it's important to consult with a qualified practitioner - especially a naturopathic or integrative doctor who understands your unique needs - before making significant changes to your eating patterns.
Personally, I’ve found that something as simple as extending the window between my last meal and the next day’s breakfast has made a noticeable difference in how I feel. I usually finish dinner around 6:30 p.m. and eat breakfast around 8:30 a.m., which gives me a fasting window of about 14 hours. Some days it stretches closer to 16 hours, depending on how I’m feeling. During that time, I stick to water or herbal teas. I’ve noticed more mental clarity in the mornings and a greater sense of balance overall.
I also try to space my meals by at least 3 hours and 45 minutes - something I picked up from reading about digestive rhythms and metabolic cycles. It seems to give my body time to fully process one meal before starting the next, which intuitively makes sense to me.
Another fascinating approach is alternate-day fasting, which follows a different rhythm. Dr. Michael Greger, both a medical doctor and respected voice in evidence-based nutrition, has compared various methods in his writings on fasting. His balanced, science-informed perspective has helped deepen my understanding and encouraged me to explore these ideas thoughtfully rather than rigidly.
I'm grateful for how much the body can teach us when we slow down and pay attention to its signals. Fasting, for me, has been less about restriction and more about creating space - physically and mentally - to support health in a gentle, sustainable way.
Even better, see the 2025 book Fasting Cancer by Dr. Valter Longo which explains how to use fasting to treat each specific form of cancer.
