New Discoveries
New (Fascinating) Findings on the Connection Between GLP-1 & Your Kidneys 💡🩺
If you’re into optimizing your metabolic health or just staying on top of the latest research, you need to know how GLP-1 impacts your kidneys. A recent review took a close look at how the incretin hormone GLP-1 and related therapies (like GLP-1 receptor agonists and DPP-4 inhibitors) do more than just lower blood sugar—they actually affect kidney function too.
GLP-1 and GIP (gut hormones) are known for their role in insulin secretion and glucose metabolism. But based on recent research, we now know these hormones also influence fluid and electrolyte balance—not just through insulin modulation but directly via the kidneys and gastrointestinal tract.
It turns out that GLP-1 receptor agonists and DPP-4 inhibitors may increase natriuresis (sodium excretion through urine) and even improve renal blood flow in people with type 2 diabetes (T2DM). What's really intriguing is that the renal benefits of GLP-1 might extend beyond just blood sugar control—these therapies could help reduce renal risk, even in those with diabetes-related kidney issues.
In other words, these treatments could offer a multi-layered approach to kidney health that’s still being uncovered. If you're managing T2DM or aiming to improve metabolic function, exploring the kidney-protective effects of GLP-1 therapies might be worth your time.
To get the full scoop on GLP-1's and how to use them safely and effectively in proper doses, check out my recent podcast episode with Dr. Tyna Moore—”Ben’s Shocking Self-Experiment With Semaglutide, The Surprising Facts About GLP-1 & Why GLP-1’s May Not Be The Big, Scary Drugs You’ve Been Led To Believe“—where we discuss how to leverage GLP-1’s benefits with lower doses than typically prescribed.

A Walkthrough of My New Blood Test Results 🧬🩸
I just got my results back from the 10X Health blood test—and you’re going to want to see this.
In this video, I break down exactly what my recent blood test revealed about my body, including some fascinating insights into my nutrient needs, vitamin D levels, liver enzymes, and even how my body metabolizes caffeine. Plus, I’ll show you how my blood test results can be paired up with 10X Health's comprehensive genetic analysis to give me an even more complete picture of my health.
I also dive into the importance of testing conditions—including whether or not to eat, fast, or workout before testing—so you can get the most accurate results possible.
To bring you up to speed, 10X Health offers a blood test as well as a Precision Genetic Test, which analyzes your unique genetic blueprint to give you tailored recommendations—in the form of a 400+ page analysis—on nutrition, lifestyle, and even the best types of foods for your body. You receive a Nutrition Analysis, a Weight Analysis, and a Precision Nutrition Plan based on your one-of-a-kind biology—this way, you can optimize your diet, recovery plan, and overall performance. Why guess when you can know?
The level of detail here is next-level, and it’s changing the way I approach my nutrition and performance. You can check out the video breakdown of my results here.

📢 This Week in Health & Performance: What the Latest Research Says 🚀
🪥 Toothpaste Tech: Not all hydroxyapatite is created equal! Nano vs. micro hydroxyapatite can make a difference in dental health—find out why some types are more effective at remineralizing enamel (learn more here).
📉 Blood Glucose Reality Check: Continuous glucose monitors (CGMs) often overestimate blood glucose levels. Instead of focusing on average values, track the frequency of glucose spikes and how long they stay elevated after meals to get a clearer picture of metabolic health (full study here).
🥩💪 Animal vs. Plant Protein: A recent meta-analysis suggests animal proteins are more anabolic than plant-based options, especially for older adults. Omnivores benefit from around 1.6 g/kg daily protein, while vegans may need more to support muscle size and strength (read the analysis here).
🏋️ The Need for Carbs Pre-Workout Is a Myth? Turns out that it’s probably not essential to consume carbs before strength training sessions. The latest research suggests you can skip the pre-workout carbs without compromising performance (read more here).
📌 Key Takeaway: Stay ahead of the curve with insights on optimal protein sources, glucose monitoring, and smarter oral health practices.

Product Of The Week
::: Boost Protein & Nutrient Absorption With 10% Off MassZymes 💪::
You’ve probably heard the old-school myth that more protein automatically means more muscle growth. It’s a lie. 
Just because you’re downing 40 grams of protein from an 8-ounce chicken breast doesn’t mean your body is actually absorbing it. The truth? Your small intestine can only absorb protein that’s broken down into amino acids—and without the right enzymes, most of that protein just ends up in the toilet.
Enzymes are crucial for protein and nutrient absorption, but here’s the problem: Most enzyme supplements on the market don’t cut it. They either lack the right kind of proteolytic enzymes or simply don’t have enough to make a difference.
The enzyme formula I trust and personally use is MassZymes by BIOptimizers. It’s packed with five different types of protease and other key enzymes to optimize digestion and ensure your muscles actually get the building blocks they need.
If you’re serious about muscle growth, MassZymes is the real deal. Plus, they back it up with a 365-day money-back guarantee, so you’ve got nothing to lose.
Head over to BIOptimizers and use code BEN10 for 10% off your order.
