The book I couldn't find, so I wrote it

When I went looking for one book that covered every lab that matters for aging well — each with its optimal range, how to move the number, and the latest research to back it up — I couldn't find it. So I wrote it.

Feel Like Yourself Again is your plain-English guide to the six pillars of midlife health: which labs to ask for, what the optimal ranges really are, and the low- and no-cost ways to shift them. Understanding your own labs shouldn't require a concierge doctor or a $10,000 course. So I put it all in one place — studies and all. For the price of a book, the knowledge and empowerment are yours.

This book is for you if…

You've been told your labs are "normal" — but you know something's still off
You're in your 40s, 50s, or 60s and refuse to accept that feeling terrible is just "aging"
You're tired, foggy, gaining weight, losing hair, or losing your libido, and want real answers
You want to walk into your next appointment informed and confident, not dismissed
You'd rather prevent chronic disease than manage it for the rest of your life
You're curious, smart, and ready to become the CEO of your own health

You don't need a medical background. You just need to be willing to learn — I'll handle the translation.

The six pillars of midlife health

1

Metabolic

Blood sugar, insulin, and the markers behind energy, weight, and long-term disease risk

2

Hormones

Estrogen, progesterone, testosterone, and the perimenopause/menopause/andropause story no one explained to you

3

Thyroid

The full panel most doctors skip, and why “normal” TSH alone misses so much

4

Cardiovascular & Inflammation

The markers that actually predict heart risk, beyond standard cholesterol

5

Vitamins, Minerals & Nutrients

The deficiencies quietly driving fatigue, mood, and brain fog

6

Infection & Immune

The immune and inflammatory signals worth watching as you age

Feel Like Yourself Again walks you through every lab that matters, organized into the six systems that make or break how you age:

For each lab, you get the same three things: the optimal range (not just "normal"), what the number actually means, and the low- and no-cost ways to move it in the right direction.

What you won't find anywhere else

Optimal ranges, front and center — the functional targets tied to thriving, not the sick-population averages on your lab report
Every claim backed by research — hundreds of citations, so you never have to take my word for it
Track-your-own-labs tables — fill in your own numbers and see exactly where you stand
How to actually change the number — food, lifestyle, supplements, and when to ask your provider about more
Written by a coach, for real people — no jargon walls, no fearmongering, no medical gatekeeping

Understanding your own labs shouldn't require a concierge doctor or a $10,000 course. For the price of a book, the knowledge and empowerment are yours.
