Deepinder Goyal, co-founder of Zomato, recently sparked deep curiosity and conversation by sharing a compelling theory he and his team at Continue have been researching—the Gravity Aging Hypothesis. This hypothesis suggests that gravity, a fundamental force we experience every day, may be a key, overlooked factor that accelerates human aging, especially through its effects on blood flow to the brain.
Understanding the Hypothesis
The core idea is simple yet profound:
Because humans live upright for most of their lives, gravity pulls blood downward, away from the brain, reducing cerebral blood flow incrementally over decades. This diminished blood flow particularly stresses critical brain regions like the hypothalamus and brainstem, which regulate essential body functions such as heart rate, hormone release, thermoregulation, inflammation, and immune response. The resulting dysfunction in these areas may accelerate systemic aging, manifesting as faster biological decline in the body.
Scientific Foundation and Research
- The hypothesis is backed by over two years of rigorous study, dialogues with hundreds of scientists and doctors worldwide, and extensive literature review.
- It connects well-established facts—upright posture, high metabolic demand of neurons in key brain regions, and the gradual decline of cerebral blood flow (CBF) starting early in life.
- The theory proposes that much of aging may begin in the brain (“brain-first and gravity-driven aging”), marking a shift from traditional views focused mostly on body wear-and-tear.
- Supporting clues include the longevity of animals like bats, which spend considerable time inverted to aid brain blood flow, the benefits of yoga postures involving head-below-heart positions, and the observation that shorter individuals often live longer—possibly due to shorter distances blood needs to travel against gravity.
Implications for Longevity and Health
If gravity-induced brain aging is fundamental, this opens new avenues for lifestyle interventions aimed at increasing brain blood flow and mitigating its chronic decline:
- Passive inversion therapies using inversion tables have shown preliminary promise, increasing brain blood flow by ~7% after six weeks—potentially reversing a decade of age-related loss.
- Yoga postures and simple positional shifts (legs-up-the-wall) that place the head below the heart can also enhance cerebral perfusion.
- Aerobic and resistance exercises, good sleep, hydration, cold or heat exposure, and a diet rich in nitrate-heavy greens, omega-3 fatty acids, and key micronutrients support brain vasculature health and longevity.
Support from Eminent Scientists
Several leading researchers from renowned institutions have expressed intrigue and optimism about this hypothesis:
- Dr. Satchidananda Panda (Salk Institute) sees it as a transformative bridge linking biology and clinical innovation.
- Dr. Rachael Seidler (University of Florida) notes its potential to reshape views on aging and promote brain health.
- Dr. David Boas (Boston University) applauds the unified model connecting vascular aging, neurodegeneration, and brain perfusion.
- Dr. Meher Juttukonda (Mass General Hospital/Harvard) praises its testability and impact potential on aging science.
Deepinder Goyal’s Message and Future Vision
Goyal shares this hypothesis not as a CEO pushing a product but as a curious human participating in the collective quest for scientific understanding and human longevity. While gravity is not claimed as the sole cause of aging, it may be the rate-limiting factor governing how long and how well we live.
The team at Continue Research is committed to funding and supporting further scientific inquiry to prove or disprove this theory—advancing our knowledge of aging and potentially unlocking additional decades of healthy lifespan, perhaps pushing human longevity toward 150 years.

Conclusion
The Gravity Aging Hypothesis invites a paradigm shift—suggesting that something as fundamental as gravity shapes the aging process in profound ways, especially via brain health. This novel lens offers hope for innovative, accessible interventions that optimize brain blood flow, enhance systemic health, and redefine what it means to age well.
Only continued research and time will tell how this bold idea alters our understanding of longevity and human biology, but the journey promises fascinating discoveries ahead.
