The "Unhealthy" 90s Diet Trend People Tried as a Joke—Now Fitness Influencers Are Hooked

Every decade has a diet that becomes a punchline. In the 90s, few eating plans got laughed at quite as much as the one that told people to load up on bacon, cheeseburgers without the bun, and steak smothered in butter.

Doctors warned against it, comedians mocked it, and plenty of people tried it half as a dare. Decades later, its core ideas have quietly become some of the most popular habits in modern fitness culture.

The Diet Everyone Loved to Mock

The plan in question is the Atkins diet. Cardiologist Robert Atkins first introduced it in the 1970s, but it exploded in popularity after his book Dr. Atkins’ New Diet Revolution hit shelves in 1992 and became a massive bestseller.

By the late 90s, “going Atkins” was everywhere. It also became a running joke, with people picturing dieters tearing through plates of bacon while refusing a single slice of bread.

What Atkins Actually Asked People to Do

The diet’s central idea was cutting carbohydrates sharply, especially in the early phase. Bread, pasta, rice, sugar, and even many fruits were limited, while meat, eggs, cheese, and fats were allowed freely.

The goal was to push the body to burn more fat for fuel. Carbs were then slowly added back in later phases, though that part of the plan got far less attention than the bacon.

Why Doctors Pushed Back

At the time, mainstream nutrition advice was firmly focused on cutting fat. Low-fat products filled grocery shelves, and the food pyramid placed bread, cereal, rice, and pasta at its base.

A diet packed with red meat and butter ran directly against that message. Many health experts worried it would raise cholesterol and heart disease risk, and some called it outright dangerous.

Then the Research Got More Complicated

In the early 2000s, researchers began putting low-carb diets to the test. Several studies found that people on Atkins-style plans lost more weight in the first few months than those on low-fat diets.

The advantage often shrank after a year, though, with both groups ending up in similar places. The findings didn’t crown Atkins a winner, but they did make it harder to dismiss the approach as pure nonsense.

How It Turned Into Keto

In the 2010s, the low-carb idea returned with a new name. The ketogenic diet, which pushes carbohydrates even lower to encourage the body to burn fat for fuel, took over social media and grocery aisles.

Suddenly, the same foods once mocked on Atkins were rebranded as “keto-friendly.” Fat bombs, cauliflower rice, and bunless burgers became trendy rather than ridiculous.

Carnivore Pushed It Even Further

Some fitness creators took the concept to its extreme with the carnivore diet, which cuts out plant foods almost entirely. Others follow a looser “animal-based” version that keeps fruit and honey on the menu.

These diets have devoted followings online, with creators sharing plates of steak, eggs, and organ meats. Supporters often credit them with better digestion and energy, though long-term research is still very limited.

Protein Became the Real Star

The most mainstream legacy of Atkins may be the modern obsession with protein. Fitness influencers now chase daily protein targets, build meals around lean meats and Greek yogurt, and treat carbs as something to time carefully.

Research does support higher protein intakes for building muscle and staying full. That’s a big reason high-protein eating has stuck around far longer than most diet fads.

What Fitness Fans Like About It

Many people find that meals built around protein and fat keep them satisfied for longer. Cutting back on sugary, refined carbs can also help steady energy and reduce constant snacking.

For lifters, a high-protein approach helps support muscle repair and growth. Combined with strength training, it can make it easier to stay lean while getting stronger.

The Concerns Haven’t Gone Away

Diets very low in plant foods can fall short on fiber, which supports digestion, gut health, and heart health. Some people also see LDL cholesterol rise when their diet is heavy in saturated fat from red meat and butter.

Sustainability is another issue. Strict versions can be hard to maintain socially and financially, and cutting out entire food groups may lead to nutrient gaps over time.

A More Balanced Takeaway

The biggest lesson from the Atkins story may be that the 90s low-fat era wasn’t the whole truth either. Cutting back on refined carbs and sugar while prioritizing protein can be helpful for many people.

Pairing that with plenty of vegetables, beans, whole grains, and healthy fats offers many of the benefits without the extremes. Anyone considering a strict low-carb or carnivore plan should check in with a doctor, especially if they have heart or kidney concerns.
