I Was a Doctor Struggling With My Own Weight

I was nearly 100 pounds overweight.

On the surface, I was practicing medicine and advising patients on nutrition, metabolism, and lifestyle. Privately, I was living in a body that didn’t respond the way the standard model said it should. I understood the science, the equations, the macronutrient breakdowns, and the exercise prescriptions. But understanding the theory didn’t translate into sustainable results for me.

At first, I didn’t question the model. I questioned myself. I assumed I wasn’t disciplined enough or consistent enough. So I did what many of my patients were doing. I tracked my calories more carefully. I reduced carbohydrates. I experimented with fasting. I increased the intensity of my workouts. Each new strategy felt like the one that would finally solve the problem.

And each time, the pattern repeated. There might be initial progress, but it rarely lasted. The weight would plateau or return, often with more frustration than before.

What unsettled me most wasn’t just the number on the scale. It was the disconnect between what I knew intellectually and what I was experiencing physically. If the model was universally correct, why wasn’t it producing consistent outcomes for everyone, including me?

That question pushed me beyond the traditional framework and toward something that wasn’t emphasized in my early training: genetic variability. The more I studied it, the clearer it became that metabolism is not uniform. Two people can follow similar plans and have very different physiological responses, not because one is more disciplined, but because their biology is different.

When I eventually analyzed my own genetic profile, the results were clarifying. Many of the strategies I had been forcing myself into were poorly suited to how my body actually functioned. My metabolism didn’t respond well to prolonged high-intensity exercise. My carbohydrate tolerance was different than expected. My hormonal response to stress and dieting required a more tailored approach.

In other words, the issue wasn’t simply effort. It was compatibility.

Once my strategy aligned with my genetic and metabolic patterns, the process changed. The weight began to come off more steadily. My hunger became more manageable. My energy stabilized. Perhaps most importantly, the experience no longer felt like a constant battle with my own body.

That personal transformation reshaped how I practice medicine today. When a patient tells me they’ve tried everything and nothing has worked, I no longer assume the issue is a lack of discipline. I ask whether the strategy they’ve been following was ever appropriate for their physiology in the first place.

In many cases, people are not failing their diets. They’ve simply never been given a plan that fits the way their metabolism actually works.
