A Dangerous History: History of Weight Loss Drugs - Yes, They Were Around Before GLP-1's

Hi Team,

I thank you for being a member and wanted to provide you with exclusive access to content on my new podcast FREEDOM TO NOURISH before it is available to the public.

Today, the discussion is about weight loss drugs. If you have ever considered taking the newest round of drugs (GLP-1's), I invite you to read the following, so you can be an informed consumer.

Today we’re taking a journey through history—one that reveals how deep our culture’s obsession with weight loss really runs. From the amphetamine diet pills of the 1930s to the Fen-Phen craze of the 1990s, and now the Ozempic era we’re living in today, people have always been searching for a so-called “magic pill.”

But behind each of these drugs is a troubling story—one that tells us more about diet culture, profit, and power than about actual health. My hope today is that as we trace this history, we’ll begin to see the patterns, ask the hard questions, and remind ourselves that our worth is never defined by the scale.

Let’s rewind to the 1930s. Imagine the era: Hollywood’s golden age, glamorous movie stars, and a growing pressure on women to be slim, poised, and perfect.

Enter amphetamines. These stimulants were originally developed to treat narcolepsy and depression, but it didn’t take long for doctors to realize they also suppressed appetite. Soon, amphetamines were being prescribed left and right as diet pills.

By the 1940s and 50s, “pep pills” weren’t just for medical use—they were marketed to housewives and working women as a way to control cravings, boost energy, and maintain that ideal slim figure.

But the cost? Addiction, heart problems, mood swings, insomnia. Women were promised beauty, but what they were really given was a chemical dependency wrapped in a shiny package.

This was the beginning of a theme we’ll see again and again: a drug that promised easy weight loss, but left behind harm that was far greater than the pounds shed.

By the 1960s and 70s, diet pills were everywhere. Doctors often prescribed what became known as “rainbow pills.” These weren’t just one drug—they were dangerous cocktails of amphetamines, diuretics, laxatives, and thyroid hormones.

Think about that for a moment. A pill that revved up your metabolism, sped up your heart, drained water from your body, and forced your bowels to work overtime—all in the name of thinness.

Then came the late 70s and 80s, with a new household name: Dexatrim.If you grew up in that era, you probably remember the commercials. Dexatrim was sold over the counter, promising to curb your appetite and help you shed unwanted pounds. It was marketed as safe, modern, and effective.

But Dexatrim contained phenylpropanolamine—or PPA—which was later linked to strokes and pulled from the market in 2000.

Again, the same pattern: marketed as harmless, later revealed to be harmful.

Now let’s move into the 1990s, when a new “miracle” swept the nation: Fen-Phen.

Fen-Phen combined two drugs—fenfluramine and phentermine—and was hailed as the safest, most effective weight loss treatment yet. Doctors prescribed it to millions of people, and patients lost weight quickly.

It felt like the dream had finally arrived.

But within just a few years, reports surfaced of devastating side effects: heart valve damage, pulmonary hypertension, even death. By 1997, Fen-Phen was pulled from the market.

The lawsuits that followed were massive—billions of dollars paid out to those harmed.

And yet, once again, we see the cycle: a cultural obsession with thinness, the promise of a quick fix, the rush to market, and the eventual devastation.

After the Fen-Phen disaster, the diet industry and pharmaceutical companies looked for new ways to keep people buying.

One was Alli—the over-the-counter version of Orlistat. Its promise? You could eat what you wanted, and Alli would block the fat from being absorbed. The catch? The fat had to go somewhere. Side effects included stomach pain, diarrhea, and something so memorable it became a joke: “anal leakage.”

Around the same time, supplements like Ephedra became wildly popular. Sold in health food stores and gyms, Ephedra was promoted as a “natural” weight loss aid. But “natural” didn’t mean safe. Ephedra was linked to heart attacks and strokes, and it was banned in 2004.

Each time, the pattern was the same: marketed as a solution, exposed as dangerous, eventually banned or restricted.

And now, here we are. Today, the names are different: Ozempic, Wegovy, Mounjaro.

These GLP-1 drugs were originally created to treat diabetes, but are now being prescribed—often aggressively—for weight loss.

There’s no question: these drugs can result in significant weight loss. But the side effects are real too—nausea, vomiting, gastrointestinal issues, gallbladder problems, muscle loss. And because these drugs are so new, we don’t yet know the long-term consequences.

History has shown us that every generation has its “miracle cure.” And every time, the promises are bigger than the truth.

So the question we have to ask ourselves is: Are we repeating history? Are we once again chasing thinness at any cost?

The story of weight loss drugs isn’t just about science or medicine—it’s about culture. It’s about how diet culture convinces us that our bodies are problems to be fixed, and how the pharmaceutical industry profits from that pain.

When we step back, we see the same cycle repeating over and over: the hype, the harm, and the heartbreak.

So maybe the real “miracle” isn’t in a pill at all. Maybe it’s in choosing to step off the hamster wheel of diet culture. To nourish our bodies, trust ourselves, and find peace outside of numbers—whether on a scale or on a pill bottle.

Until next time, remember: your worth has never been measured in pounds.
