Tracking Macros Was So Much Easier When I Made a GPT

Tracking Macros was always a struggle

Until I learned this GPT hack and reached weight loss goals I’ve had for years

For years I had the same goal: get a six pack. Fifteen years of “this is the year,” and then come December, no six pack. I’d tried tacking macros on and off, but no system seemed to keep my attention. After entering my 40s, I felt like it might not happen for me. Everyone kept telling me to stick with tracking macros, and I even tried MyFitnessPal. It helped a little (I even reached a 5 day streak at one point), but like the others, I fell off the wagon. After 40, I was annoyed that, even though I was eating healthier than in my 20s and 30s, I was now gaining weight easier than ever.

Was it just getting older and I was now watching weight loss slide out of reach? Or was I doing something else wrong?

Fast forward to this year. I was using AI for several roles in my home business. One day I saw an ad that claimed it would “log my calories easily,” complete with promises I felt I’d heard before. And no, I didn’t try the app. Instead (I admit, this next part will sound very millennial), but a lightbulb went off in my brain: what if I used ChatGPT? I already engineered several custom GPTs (which isn’t hard) and decided to try it out almost as a last ditch effort for a six pack.

It’s important to note one thing

Weighing food and logging exact ingredients is naturally the gold standard. What I did is obviously little less scientific as I didn’t weight everything. But honestly I figured if I was 90–95% accurate with my macros, it was better macro tracking than I’d ever done in the past. I decided it was still a vast improvement. Here are the results of my experiment…

What were the results of the “Tracking Macros” GPT experiment?

In 3 months, I went from 186 lbs to 171 (which felt steady and sustainable). I built some great habits; even when I wanted Doritos, I logged it because there was no one to ‘hide’ it from. The data needed to be accurate — meaning lying to ChatGPT was pointless, so I was the most consistent and precise with my food I’d ever been. It was like a budget, which actually felt more freeing than ever. As I did weigh ins through the weeks, I was pleased to see most my weight loss was in fat (I used one of those digital bluetooth scales with the app to track your fat and muscle gains). My wife noticed I was actually sticking with macro tracking for the first time. And more importantly, ABS were coming through (also a first)! She said she was impressed how well I was doing with my new setup.

Now, my wife is a self-described ‘slow adopter’ to AI tools, but decided to try it herself. Two months in, she said she was closer to her weight loss goal than she’d been in years. She actually said it was how she got fully ‘bought in’ to AI because of how custom she could make the experience.

Is it a silver bullet? No. It’s just a far easier way to log my food; I’ve now been logging for several months and haven’t missed a day, even when we went to New York on vacation. I don’t feel restricted — in fact, I feel like I understand my body better than ever before. Below is exactly what my custom GPT does — and how your can customize one for yourself easily.
