Episode Details

It’s not a straight line. It’s not a diet. And it’s definitely not what you expect.

I started my journey on a GLP-1 in October 2024. While my doctor did what good doctors do—he gave me the warnings, the precautions, the usual advice about what to avoid and watch for—I quickly realized something was missing. No one really told me what it would feel like. More importantly, no one explained that this first month doesn’t unfold in one neat, predictable way, but instead moves along several paths depending on the person, their biology, their habits, and frankly, a bit of luck.

So, as I’ve watched friends, patients, and many people start this same journey, I’ve come to understand that the first month is less about weight loss, and far more about discovery, adjustment, and occasionally confusion. While people expect something simple, they get instead of variation, and that variation can make them think something is wrong when everything is going exactly as it should.

The Myth of the Straight Line

Most people begin this process believing they will take the medication, lose their appetite, and watch the scale steadily drop. While that story is appealing, it simply isn’t how the body works, because biology rarely follows a script, and in this case, the first month is more like learning a new language than following a plan.

What becomes clear quickly is that people fall into different patterns. While none of these patterns are right or wrong, understanding which one you are in can make all the difference in how you interpret the experience.

The Three Paths of the First Month

Some people, myself included, are what we call hyper responders. Although we don’t fully understand why this happens, the effect can be dramatic. Within about twelve hours of my first dose, something shifted in a way I did not expect, as the constant chatter in my head about food—what we used to call head hunger—simply disappeared, and I didn’t even know it had been there until it was gone.

During that first month, I lost twelve pounds, and while most of that was water and glycogen with some fat mixed in, the real change was not on the scale, but in my appetite. This dropped so noticeably that I found myself stretching out the time between doses. Interestingly enough, my obstructive sleep apnea improved, which was not something I had anticipated, but certainly appreciated.

At the same time, my doctor had warned me to drink more fluids, and that advice was critical, because much of the water we normally get comes from food, and when food intake drops, hydration must be a conscious effort. So I adjusted by adding a protein shake in the morning and increasing my iced tea throughout the day, and that simple change made a meaningful difference in how I felt. You can find my recipes for protein shakes on the recipe section of my site, terrysimpson.com.

The Normal Responders

On the other hand, most people do not have that kind of immediate response, and instead they fall into what I would call the normal responder group, where the changes are subtle at first, and because they are subtle, they are easy to miss, which leads many to think the medication isn’t working, especially when they compare themselves to others who seem to be losing weight quickly.

What they don’t notice, however, is that they are snacking less, leaving a bit of food on their plate, and skipping that second helping more often than before, and while these changes may seem small, they add up over time, because when someone tells me they only lost four pounds in a month, I translate that into nearly fifty pounds in a year, and suddenly the perspective shifts from disappointment to possibility, b
