The numbers don't
negotiate.

I built this program because I ran out of patience with "you're fine, it's just age." Every number below is mine — real, tracked, and physician-supervised — from the morning I weighed 285 pounds to today.

I was on four medications.
My doctor told me I was fine.

In early 2025, I weighed 285 pounds. My cholesterol was elevated — statin prescribed. Testosterone declining. Inflammation markers trending the wrong way. My primary care physician reviewed the panel and told me the numbers were in range.

I did what I do in every other part of my life: I found a functional-medicine physician who would read the full picture, built a protocol around my actual labs, and started tracking every output the same way I'd track a business metric. Not a supplement stack. Not a generic plan. A physician-prescribed protocol, labs re-tested on a cadence, and objective data at every checkpoint.

From February 2025 to today, that looks like roughly 80 pounds gone, a visceral fat score that moved from "Excessive" to "Acceptable," and a body fat percentage that has dropped every month it's been measured. The medications conversation has changed. The energy conversation has changed. The data made both of those things possible.

This program is the system I had to build for myself — handed to you from day one.

The tracked arc

Four checkpoints. Real numbers at each one.

My full journey starts in February 2025 — before any device was tracking. The data-documented arc begins April 21, 2025, when I recorded my first GE body-composition scan.

February 2025 · Start
285 lb. No tracking yet. Just a number on a scale and a decision.
Weight
285 lb

My starting point — acknowledged but untracked. No device data from this date. I started using the GE body-composition app on April 21, 2025, already 33 lb into the journey.

April 21, 2025 · GE Scale begins
Device tracking starts. 252 lb. Body fat at 36.4%.
Weight
252.2 lb
Body fat
36.4%
Visceral fat
17 · Excessive
BMI
35.3

Already 33 lb down from where I started in February. Protocol in place, tracking now consistent.

October 11, 2025 · InBody 270 scan
First clinical-grade InBody scan. 233.6 lb. Muscle holding.
Weight
233.6 lb
Body fat %
24.8%
Body fat mass
57.9 lb
Skeletal muscle
101.0 lb

18.6 lb lost since April. Skeletal muscle holding at 101 lb — I was losing fat, not muscle.

June 2026 · Current
48.2 lb of tracked loss. Visceral fat: Acceptable. Still moving.
Weight (GE)

Weight (InBody)

Why two body fat numbers appear at the June 2026 checkpoint

My GE body-composition scale (25.9%) and the InBody 270 clinical scanner (14.7%) were both measured within three days of each other and both reflect the same body — they disagree because they use different measurement methods and electrode configurations. The GE scale uses 4-electrode bioelectrical impedance; the InBody 270 uses an 8-electrode segmental analysis that measures arms, legs, and trunk independently, which is more precise. Neither number is wrong. Both show the same direction: consistent, sustained improvement. Every patient in the Activtrim program is tracked on the same standardized device so their data is internally consistent over time — that's what matters for protocol decisions.

Your numbers are waiting to move too.

I built a system to do this for myself. Now I hand it to you from day one — physician review, a protocol built around your labs, and tracking that holds the line. The consult is free. That's where it starts.
