Ben Greenfield’s Weekly Roundup: December 12


*This* Simple Upgrade Turns a Boundless Bar Into Something You’d Expect Behind a Bakery Counter

Boundless Bar

If you haven’t tried the world’s first ketone-powered protein bar yet, now is the perfect time to experience ketone-fueled energy (without the bitter ketone taste or the strict keto diet).

Here’s a simple, dairy-free, mouth-watering keto frosting that pairs *perfectly* with the sticky goodness of the Boundless Bar Cinnamon Roll flavor.

Keto Frosting Recipe (Dairy-Free):

In a mixing bowl, whisk together:

  • 1 can of coconut cream
  • 4 dropperfuls of vanilla stevia (Omica Organic is a clean, great-tasting option)
  • ½ tsp vanilla extract
  • A pinch of salt

Spread generously over your Boundless Bar.

Eat. Moan. Repeat.

You can grab your bars here at BoundlessBar.com—and bonus points if you drop a comment with your own Boundless Bar recipe idea!

This Week in Health & Performance: What the Latest Research Says

🔥 The Muscle-Gain Sweet Spot: A small calorie surplus—between 150–300 kcal/day (5–10% of total), ideally from protein—maximizes muscle gain while minimizing fat. Surpluses above 15% lead to significantly more FAT gain, so don’t go overboard (study here, and another study).

⏱️ Fasting vs. Calorie Restriction: New evidence shows fasting can help with structure and appetite control, but for long-term weight loss, calorie restriction still wins. Fasting isn’t superior overall, but it can still make adherence easier (read the study here).

 ❄️ Humans Adapt FAST: Like Japanese Ama divers, humans—especially kids—adapt quickly to environmental stressors like cold exposure, breathwork, and load-bearing movement. Translation: train adaptability early to make your kids more resilient (full study here).

🧴 Microplastic Panic? Maybe Overblown: While plastic consumption still poses health risks, total human exposure—especially the dramatic “credit card a week” claims—may be far lower than popular narratives suggest (analysis here).

Key Takeaway: Muscle gain, metabolic health, and environmental resilience all come down to small, strategic habits, so dial in your calories, structure your fasting intelligently, and train your body to adapt.

::: Save 15% on ZBiotics Pre-Alcohol: My Go-To Holiday Hack 🍷🧬 :::

If you’re anything like me, the holiday season brings a few extra clinks of the glass.

And that leads to the familiar dilemma: do you enjoy the celebration tonight… or pay for it in tomorrow’s performance?

For the past few years, I’ve relied on one of my favorite holiday biohacks to help me do both: ZBiotics Pre-Alcohol.

This genetically engineered probiotic is designed to break down acetaldehyde, the toxic byproduct of alcohol that contributes to feeling “off” the next day.

I’ve used ZBiotics Pre-Alcohol through multiple holiday seasons, travel stretches, and social events, and the difference is absolutely noticeable.

Drink one before your first cocktail, and you’re essentially giving your body a molecular head start. You’ll wake up ready for your workout, family time, travel day, or whatever December throws your way—even after having fun the night prior.

As you head into celebration season, don’t just toast; biohack your night and protect your next morning.

Try ZBiotics Pre-Alcohol and experience the shift for yourself. Right now, you can use code BENG here, and you’ll save 15% on your first order.

P.S.: ZBiotics offers a 100% money-back guarantee. So if you don’t feel the difference, they refund you—no questions asked.
