Are 'biohack' methods effective?

Unlocking a longer, healthier life in your own hands

- SKINVESTING DR. KAYCEE REYES

Manila's elders are living longer than ever, yet many spend those extra years shuttling between clinics. As a skin specialist, I see sun-damaged skin and glycation spots. As a preventive-medicine physician, I know that healthspan—the years we remain energetic and disease-free—matters more than sheer lifespan. And as a writer, I know how the words we choose shape our relationship with aging. The buzzword "biohacking" may conjure images of gadgets, but it simply means applying science to live better.

The science is clear: Aging begins in our mitochondria, the power plants of our cells. When we eat too much and move too little, these organelles spew reactive oxygen species that damage DNA and proteins. Caloric restriction, eating until you are satisfied (not stuffed), slows mitochondrial damage. Giving your body a 12 to 16-hour break from food overnight allows cells to clean up damaged parts. Pair those habits with daily movement, whether brisk walking, dancing, or gardening, and you encourage new mitochondria to grow. Small, steady habits beat extreme diets every time.

Food is our most powerful lever. One "aging force" is glycation: Excess sugar sticks to proteins and DNA, stiffening tissues and clogging arteries. Sugar hides in unexpected places, so treat it as a treat, not a health food. Commercial milk can contain as much as half a soft drink. Drink milk because you enjoy it, not because you think it will strengthen your bones.
