Actor and fitness enthusiast Kunal Kapoor recently sparked a conversation on modern biohacking by calling his grandfather the “original biohacker,” crediting his longevity until age 94 to simple habits such as walking an hour daily, eating small meals, chewing food slowly, finishing dinner before sunset, and fasting every Sunday. Dietitian and fitness expert Garima Goyal explained that these practices, now often rebranded as wellness trends, are backed by science and have long been part of traditional lifestyles. Slow eating can improve digestion and satiety, early dinners may support better metabolic health and circadian rhythms, periodic fasting can enhance insulin sensitivity in some individuals, and daily walking remains one of the most evidence-based ways to improve cardiovascular health, blood sugar control, mobility, mental well-being, and longevity. The key takeaway is that many habits now marketed as biohacks are actually simple, time-tested lifestyle practices whose power lies in consistency rather than expensive gadgets, supplements, or complex routines.
