Willpower Is B.S.: Food Noise, Healthspan, and What Actually Changed My Life

For decades, I started every New Year the same way.

In January, I promised myself this would be the year.

By February, I tried harder.

Every spring, I adjusted the plan.

And by summer or fall, the weight crept back.

That cycle repeated not because I lacked knowledge, discipline, or effort. Instead, it repeated because I misunderstood biology — at least when it came to myself.

This year is different.

For the first time since Ronald Reagan was first elected, weight loss is not at the top of my New Year’s resolution list. Not because I stopped caring, but because I lost 45 pounds with the help of Zepbound over the last year. More importantly, however, I learned something that reshaped how I think about obesity, healthspan, and shame.

Before anything else, let me be clear: this is not medical advice. This is a story. Anecdotes are not evidence, even when the anecdote is from a physician. Nevertheless, stories help us understand science when data alone fails to move us.

And this story matters.

I Had Willpower. That Wasn’t the Problem.

For years, people told me — and millions of others — the same thing: move more and eat less. At first glance, that advice sounds logical. After all, calories matter. Energy balance matters.

However, reality is more complicated.

To begin with, I am a surgeon. Surgical training requires extraordinary willpower. Moreover, I’ve logged food meticulously, cooked Mediterranean-style meals, exercised consistently, and followed every evidence-based recommendation I’ve ever given patients.

Meanwhile, Oprah has willpower. Olympic athletes have willpower. Yet obesity persists.

Sure, willpower works briefly. In fact, go on a liquid protein diet, and the weight will fall off quickly. Unfortunately, the food noise remains. Eventually, biology wins. Always.

In the same way you cannot positive-think your way out of hypertension, cholesterol, diabetes, cancer, or heart disease, you cannot willpower your way out of obesity. Obesity is a disease. It is not a moral failure.

Ironically, I knew this intellectually. Nevertheless, I failed to apply it to myself. We have a name for that: cognitive dissonance.

Food Noise Was the Missing Concept

The real turning point did not come from reading another study. Instead, it came from listening to people I trusted.

One colleague quietly lost weight on a GLP-1. Another friend told me something more striking: the food noise stopped. Alcohol lost its appeal. Smoking no longer called.

That phrase — food noise — suddenly explained decades of struggle.

To illustrate, think of sleeping near Lake Shore Drive in Chicago. At first, traffic noise dominates your awareness. Eventually, it fades into the background. Only when you leave the city do you realize how loud it was.

Food noise works the same way.

When GLP-1 therapy quieted that background signal, eating slowed naturally. Meals ended without effort. Desire changed without rules. Biology shifted.

Notably, calories did not lower my stress. Calories did not improve my sleep. Calories did not stop snoring. Biology did.

The Unexpected Early Benefits

Interestingly, weight loss was not the first change I noticed.

Sleep improved almost immediately. Stress dropped dramatically. Commutes that once registered hours of physiologic stress now barely registered minutes. Appetite normalized. Eating slowed.

These changes matter because sleep and stress directly affect inflammation, metabolic health, appetite signaling, and long-term disease risk. In other words, healthspan improved before the scale reflected anything meaningful.
