New Discoveries
AI Assistant Designed to Better Your Health & Eliminate Guesswork!? Yes, It's Real & FREE to Use 🤖
Most people don’t fail at their New Year’s health goals because they are incapable…
They fail because they don’t know how to turn their vision into daily actions that move the needle.
That’s why my team built Ellen.
Inspired by LIFE Network’s initials, “L” and “N,” which sound like “Ellen” when said aloud, this AI-powered health transformation coach is built directly into LIFE Network and is completely free to use.
She pulls from the world’s leading health experts to turn real science into simple, actionable guidance across:
💪 Fitness
🥗 Nutrition
😴 Recovery
🧠 Mental well-being
🌱 Lifestyle habits
As you head into the new year, you can use Ellen to:
1️⃣ Clarify your health goals.
Ask: “I want to improve my health this year. Help me identify what I should focus on first.”
This lets Ellen narrow things down so you are not trying to fix everything at once.
2️⃣ Define your starting point.
Ask: “Based on my current habits and lifestyle, where should I begin?”
This helps Ellen meet you where you are and build a strategy around your life.
3️⃣ Create an actionable plan.
Ask: “Can you help me create a simple, realistic plan I can follow weekly?”
Ellen will break things into manageable actions instead of big, overwhelming changes.
4️⃣ Prioritize what matters most.
Ask: “What should I focus on first to see the biggest impact?”
This keeps you from getting distracted by trends or conflicting information.
5️⃣ Adjust and stay consistent
Ask: “How should I adjust this plan if my schedule or energy changes?”
This helps you stay consistent without feeling like you failed when life gets busy.
Using Ellen this way turns her into a personal health concierge who helps you move from intention to action.

This Week in Health & Performance: What the Latest Research Says
🥤 Ketones & Liver Health—Myth vs. Reality: Fears about ketones harming the liver stem from an extreme mouse study using the human equivalent of ~28 shots of a ketone precursor in genetically altered mice with reduced liver protection (study here). But in contrast, multiple human-relevant studies show no hepatotoxicity and even improvements in liver markers with exogenous ketones (read more here and here).
🦵 Collagen for Power & Tendon Health: In a 16-week randomized controlled trial in young sedentary men, collagen peptide supplementation significantly increased calf power output and Achilles tendon stiffness, which are key markers for performance and injury resilience (full study here).
🏃 Protein & Endurance—An Unexpected Edge: Protein appears to boost endurance performance not just through muscle support, but by essential amino acids reducing central nervous system fatigue, which helps athletes go longer and harder than expected (study here).
Key Takeaway: Extreme study designs often drive scary headlines, but real-world human data tell a different story: ketones can be liver-safe, collagen strengthens performance-critical tissues, and protein can enhance endurance by protecting the brain as much as the body.

Product Of The Week
::: Save 20% on the Headband That Trains Your Brain Like a Muscle :::
If you’ve ever wanted meditation, focus, and sleep training to come with real, measurable feedback, Muse delivers exactly that.
Muse S Athena is a brain-sensing headband that trains your mind using real-time biofeedback.
It measures electrical brain activity (EEG), blood oxygenation in the prefrontal cortex (fNIRS), heart rate, breathing, and movement, then turns those signals into live guidance you can actually use to sharpen focus, reduce stress, and improve sleep.
While most wearables just track data, Muse actively trains your brain.
During biofeedback sessions, audio feedback responds instantly to brain activity. Calm brain, you hear birds. Distracted brain, stormy weather. This closed-loop system teaches direct self-regulation through repetition and feedback.
Muse is also one of the most accurate sleep wearables on the market, detecting sleep stages in real time and adapting guidance through the night. Clinical research shows users fall asleep 55% faster and improve sleep quality by 20%.
Built on over 1 billion minutes of real brain data, supported by more than 500,000 users, and validated by 200+ research studies (including Mayo Clinic research), Muse is one of the most evidence-based tools I’ve seen for training mental fitness.
