Something I've Been Using — Sharing in Case It's Useful

I've had a few people ask me about tools I use to track how my body responds to food, so I figured I'd just write a quick post about it.

I've been using Lingo's CGM (continuous glucose monitor) recently, and it's been a genuinely interesting way to see what's actually happening under the hood — not guessing, just data. If you're curious, I have a code that gets you 50% off (use code: REF-US-q5jdSmDXa5E, or just use this link and it's applied automatically). No pressure at all — just sharing since a few of you asked.

Anyway, here's why I think it's actually useful, not just a gadget.

Why I Like Having This Data
A CGM shows you, in real time, how your blood sugar responds to different foods, workouts, sleep, and stress. Instead of following a generic plan and hoping it's working, you get to see what's actually going on with your body specifically.

For me, it's helped with:

• Seeing which foods spike my blood sugar (and which ones barely move it)
• Noticing how training affects my energy and recovery
• Fine-tuning nutrition based on real feedback instead of trial and error
• Building habits around what my body actually does, not assumptions

The Insulin Sensitivity Piece
This is the part I find most interesting, especially for anyone chasing physique goals — building muscle, getting lean, whatever your focus is.

A CGM doesn't measure insulin directly, but it gives a solid proxy for insulin sensitivity — basically, how efficiently your body handles carbs and gets nutrients where they need to go. You can see this in how high your glucose spikes after a meal and how quickly it comes back down.
​
Why it matters:

• Better insulin sensitivity generally means better nutrient partitioning — more of what you eat goes toward muscle and recovery, less gets stored as fat
• Sharp, prolonged spikes can be a sign your body is working harder than it needs to with certain foods, which can affect energy and hunger
• Consistent training actually improves insulin sensitivity over time, so this is also a way to see the payoff from putting in the work

Not trying to make anyone afraid of carbs or chase a "perfect" number here — just pointing out that this kind of feedback can help your nutrition and training work with your body instead of against it.

If you ever want to try it out, the code's above. And if you do, let me know what you notice — I'm always curious to compare notes.
