The Chorus of “Just Eat Less”

Spend a few minutes on social media, and you will hear it. On Bill Maher's podcast the other day, I heard it. Two people who know less about GLP-1 drugs than almost anyone, opining about how GLP-1s are horrific.

Bill Maher says, “Just eat less.”

Jillian Michaels warns that GLP-1 medications are dangerous. Did she even graduate from college?

Meanwhile, a rotating cast of gym bros, coaches, and influencers insists that anyone using these medications is taking the easy way out.

At first glance, these seem like different voices. A comedian, a fitness personality, a group of online trainers.

However, they are all saying the same thing.

If you are overweight, this is your fault.

If you need help, you are weak.

If you use medication, you are cheating.

That message travels well. It is simple. It fits into a tweet. It sounds like common sense. Science shows us that fat shaming doesn't work (reference).

It is also wrong.

Who Is Doing the Shaming—and Why

The fitness industry has something to lose here, and that part is easy to understand. Entire businesses are built on the idea that weight loss is a matter of discipline. Follow the plan, buy the program, track the macros, and success will follow. If it doesn’t, the explanation is built in.

You didn’t try hard enough.

However, the criticism does not stop there.

When someone like Bill Maher reduces obesity to “just eat less,” it is not about selling a diet plan. Instead, it reflects something else entirely. A kind of cultural impatience with complexity. A belief that if a problem can be described simply, it must also be solved simply.

And when that belief meets a condition like obesity, the result is dismissal.

If I don’t struggle with this, then it must not be real.

If you do struggle, then you must be doing something wrong.

That is not analysis.

That is a failure of imagination.

The Problem with Simple Answers

Medicine has a long history of being wrong in simple ways.

We once believed ulcers were caused by stress alone. Then came Helicobacter pylori and antibiotic treatment. We once thought hypertension was simply a matter of salt intake and personality. Then we developed therapies that addressed the underlying physiology.

Obesity has followed a similar path, except we have been slower to let go of the old explanation.

“Eat less, move more” is not incorrect.

It is incomplete.

Because it ignores the system that determines how much you want to eat, how often you think about food, and how your body responds when you try to lose weight.

The Part I Didn’t Admit

For years, I saw the damage this thinking caused.

I ran support groups for patients struggling with weight. I watched them come in carrying not just pounds, but shame. They believed they were weak, that they lacked discipline, that something about them was broken.

We worked to change that.

We talked about biology. About appetite regulation. About how the body defends weight. We tried to replace blame with understanding.

And yet, I quietly held myself to a different standard.

I didn’t blame my patients.

I blamed myself.

The Surgeon Who Thought He Could Outwork Biology

If anyone should be able to power through something, it is a surgeon. That is the job. Endure long hours. Stay focused. Push through fatigue. Delay gratification.

So I assumed I could do the same with weight.

I tried diets. I cleaned things up. I ate vegetables, cut back on certain foods, and experimented with structure. And like many people, I saw results.

At first.

Weight loss is not the mystery.

Weight maintenance is.

Because over time, the same thing happened again and again. The body adapted. Hunger increased. Energy dipped. The system pushed back.

And eventually, the weight returned.

What the Data Shows (and Why It Matters)

When you look beyond personal stories and examine long-term studies, the pattern becomes clear.

In the Diabetes Prevention Program, participants lost weight early, then gradually regained some of it. In the Look AHEAD trial, an intensive lifestyle intervention produced initial success, but the gap narrowed over time.

Observational data suggest that only a small percentage of people—often cited around 3 to 5 percent—maintain significant weight loss at five years.

That number should change the conversation.

Because it tells us this is not a widespread failure of discipline.

It is a predictable outcome of a biological system.

The Loop We Keep Ignoring

Weight gain does not happen in isolation. It is part of a loop.

Sleep worsens, which increases appetite. Movement becomes uncomfortable, so activity declines. Food becomes more rewarding, not less, because it offers relief.

Then intake increases.

Then the cycle repeats.

And yet, into that loop, we continue to insert the same advice.

Try harder.

What Finally Changed

For years, I thought I just needed to try harder myself.

I was wrong.

Today, I am down fifty pounds.

Not because I discovered a better diet, but because something changed in the system itself.

I started a GLP-1–based medication.

The effect was immediate in ways I did not expect. My sleep improved. My snoring stopped. That alone changed my appetite and energy. Then something else happened.

The noise went away.

That constant pull toward food, the background awareness that shapes decisions throughout the day, quieted.

From there, everything else followed.

I began moving more. I returned to yoga, not out of obligation, but because it felt good. Because my body allowed it.

This was not about replacing lifestyle.

It was about finally being able to live it.

What the Critics Miss

When critics say this is the “easy way out,” they misunderstand what is happening.

There was nothing easy about fighting biology for years.

What these medications do is change the biology so that effort becomes effective.

That is not cheating.

That is treatment.

The Future of Coaching (and Who Will Adapt)

The fitness world is not going away.

However, it is going to change.

The coaches who succeed will not be the ones shaming people for using medication. Instead, they will be the ones who understand how to work with it. They will help people build muscle, improve movement, and develop sustainable eating patterns once appetite is regulated.

Mediterranean and DASH-style diets still matter. They remain among the best-supported dietary patterns for long-term health. What changes is the ability to follow them.

When the biology shifts, adherence becomes possible.

Eating Without Fear

One of the most striking changes is how food feels.

You no longer need to treat eating as a constant negotiation. You can eat real food. Greek yogurt, eggs, vegetables, and fruit.

You can enjoy it.

You can eat a peach without worrying about whether you have broken a rule.

That is what happens when the noise quiets.

Where I Was Wrong—and What Comes Next

For a long time, I believed that effort alone would solve this.

I was wrong.

Not because effort doesn’t matter, but because effort without the right biology is not enough.

Science moves forward by showing us where we were incomplete. In this case, we were incomplete in how we understood obesity.

Now we are beginning to correct that.

And as we do, the conversation should change.

Less blame.

More understanding.

Less shame.

More treatment.

Because this was never about character.

It was always about biology.
