What’s the “Healthiest” Alcohol Option? Minimize Your Sugar Intake with *This* Doctor-Approved Spirit 🥂🌿

If you’re looking for the cleanest and healthiest alcohol to enjoy *without* derailing your health, mezcal might just be the answer.

According to Dr. Taryn Forrelli, a naturopathic physician, mezcal stands out as the purest spirit because it’s made from 100% agave with no added sugars or artificial ingredients.

Unlike tequila, which can contain additives, mezcal uses the whole agave heart in the fermentation process, including the prebiotic fibers known as agavins, which may help regulate blood sugar and support gut health.

In addition to its purity, mezcal has the lowest sugar and calorie count when consumed straight, making it a great choice to minimize sugar intake while still enjoying a drink. Its potential health advantages over other liquors, coupled with its smoky flavor and artisanal craftsmanship, have made mezcal the drink of choice for the wellness-conscious.

So, if you’re going to indulge, choosing a high-quality, small-batch mezcal is your best bet for a cleaner, more mindful option. For more healthy, delicious cocktail recipes, I also recommend checking out my cookbooks Boundless Kitchen and Boundless Cookbook!

The Future of Light Therapy Is Here: Say Goodbye to Sleep Struggles with the Retimer 3 🌙✨

Airline travel, jet lag, modern lighting, electronic screens, Wi-Fi, Bluetooth signaling, and other cues that fly in the face of natural daily sunlight and natural evening darkness can throw your body clock entirely out-of-whack.

Rather than fixing the problem, most people will simply begin making excuses that they’re a “night owl” or an “early bird,” all while beating up their biology with an unnatural circadian rhythm alignment.

One of my favorite solutions for getting your circadian rhythm back on track is the cool, futuristic “retimer” green-blue spectrum light-emitting glasses that help reset your body clock to its natural rhythm and shift it back to its ideal timing.

Basically, you can consider retimer’s glasses to be the complete polar opposite of blue-light-blocking glasses. Blue-light-blocking glasses block blue light from entering your eyes, while the retimer shines into your eyes with green-blue light far more powerful than what you’d get from a phone, television, computer, etc. When you use them strategically throughout the day, you can tweak your circadian rhythm forward or backward, whichever you choose.

You simply wear them while you are awake either in the morning or evening, depending on how you want to change your sleep. For example, one recommended schedule to change your sleep is typically seven days for 30 minutes each day. To treat Winter Blues, the retimer can be worn daily throughout winter or just used on the darker colder days when you want to boost your energy and mood.

To discover more about how your circadian rhythm works (and how the retimer glasses can help restore it), you can check out this article.

I’ve been using retimer’s glasses for nearly a decade, and here’s the exciting part: this company is constantly pushing the envelope with the latest biohacking tech. The result?

Retimer 3—a cutting-edge wearable backed by over 25 years of research, designed with advanced light technology to realign your sleep-wake cycle and fix circadian rhythm imbalances.

Whether you’re battling insomnia, adjusting to new time zones, or handling the demands of irregular work hours, retimer 3 offers a practical, science-backed solution to fixing poor sleep.

The retimer 3 is paired with its own mobile app, providing you with a simple method to create, manage, and monitor your sleep schedule to effectively address issues standing in your way of a restorative night’s sleep. 

Following its acclaim at global events like the World Sleep Congress and Arab Health, the retimer 3 is now available for pre-order on Kickstarter. Early backers can secure this innovative device at a special price of $109up to 45% off the retail value. 

If you’re ready to get your circadian rhythm back on track to experience better sleep, increased energy, and a brighter mood, you can visit the Kickstarter page here to pre-order one of my favorite biohacking devices!
