2. Fasting and Time-Restricted Feeding for Pets

While most pets are grazers by habit, there’s growing interest in time-restricted feeding (TRF). TRF mimics aspects of fasting biology, promoting cellular renewal and better insulin sensitivity.

In veterinary studies, dogs that ate once daily, not free-fed, showed improved cognition, lean muscle maintenance, and reduced inflammation.

Just as we use fasting to trigger autophagy, repair, and NAD+ upregulation, some veterinarians believe similar responses could benefit pets when applied carefully and under supervision.

And while you won’t find pets sipping green juice on a detox cleanse, the concept of metabolic cycling, feast and fast, is starting to reshape how longevity-minded pet owners feed.

3. Supplements: What’s Safe and What’s Hype

Not every human supplement translates to animal use. That said, some compounds are being explored for their potential to improve healthspan in dogs and cats:

• Antioxidants: Like CoQ10 and vitamin E, to protect mitochondrial integrity

• Adaptogens: Like ashwagandha or turmeric (when properly dosed)

• Joint support: Glucosamine and chondroitin are widely accepted for aging pets

NAD+ boosters, senolytics, and fasting mimetics like Mimio are designed for human biology, but the mechanisms they target (like autophagy and inflammation control) are relevant across species. While Mimio isn’t exclusively formulated for pets (...yet), the science behind it is inspiring a wave of research into how we might biohack aging in animals down the line.
