Extended daily breaks from food allow the body to shift from constant digestion to repair mode, promoting cellular renewal and reducing inflammation.

Dr Rahat Ghazanfar, Family Medicine Consultant and Clinical Director at Sheikh Shakhbout Medical City’s Longevity Clinic, describes fasting as a form of “cellular spring cleaning.”

After several hours without food, the body switches from using sugar to stored fat, activating repair processes linked to slower biological ageing.

“Anti-ageing isn’t about appearance,” Dr Ghazanfar explains.

“It’s measured by markers like blood sugar control, inflammation, muscle and bone health, heart fitness, and hormonal balance — all of which reflect how the body is ageing internally.”

Fasting mirrors time-restricted eating, shown to improve blood sugar, reduce inflammation, and support metabolic health without extreme calorie restriction.

Fasting also influences hormones, lowering insulin levels and boosting growth hormone, while easing chronic inflammation — a key driver of age-related disease.

Dr Ghazanfar stresses fasting is not one-size-fits-all. Age, gender, stress, and health conditions affect outcomes.

She warns against excessive fasting, particularly for older adults and women, which can lead to fatigue, muscle loss, or hormonal disruption.

“Fasting offers a powerful annual reset,” she says.

“The benefits last when healthy eating, mindful habits, and sleep routines continue beyond the month. Fasting is a tool to support healthspan — keeping people strong, resilient, and sharp for longer.”
