Start Here
Everything you need to know about The Habit Healers in five minutes.
Hi, I’m Dr. Laurie Marbas, a board-certified family and lifestyle medicine physician. I started The Habit Healers because most health advice gets the order wrong. It starts big: overhaul your diet, commit to a program, change everything by Monday.
That approach breaks. Reliably.
This newsletter is built on a different premise, one small, well-chosen habit, repeated until it sticks, changes more than any overhaul. The science backs this up. So does every patient I’ve ever watched succeed.
What We Cover
Everything here is organized around five areas that drive metabolic health: blood sugar regulation, nourishing movement, stress regulation, community connection, and restorative sleep.
These aren’t five separate topics. They’re one connected system. Cortisol disrupts insulin signaling, poor sleep increases appetite hormones the next day, and chronic stress changes where your body stores fat. A ten-minute walk after dinner lowers post-meal glucose, reduces cortisol, improves sleep onset that night, and becomes a conversation with your partner if you take it together. One input, four downstream effects.
We help you find the right lever and pull it.
Your Weekly Schedule
Tuesdays and Thursdays bring habit blueprints: focused guides on specific habits and the science behind them, with printable worksheets for paid subscribers.
Saturdays are deep dives. Long-form breakdowns of the biology driving everything from insulin resistance to brain health to circadian rhythm. If you want to understand why a habit works, this is your day.
Sundays give you one thing to do on Monday. Small, science-backed habits you can start immediately.
Fridays are the subscriber-only chat, a private space where paid members ask questions, share wins, and get direct answers.
You don’t need to keep up with all of it. Pick one thread and let it build.
The Periodic Table of Healing Habits
We mapped 30 micro-habits across all five areas into a single reference tool. Each one takes minutes, not hours, and the “active ingredients” listed are real mechanisms. The “side effects” are what actually happens when people start.
Find the one that fits your life this week and do it until it stops requiring effort. Then add another.

Help! I’m not understanding the amounts listed in mg. For example Protein First Facts lists Satiety Signal 500mg….Insulin Stability.
500mg of protein is a very small amount, about .02oz. What am I missing?
