Robert’s Note: If you are currently taking medications like Ozempic, Wegovy, Zepbound, or other GLP-1 agonist medications, I encourage you to read this article carefully. Consider printing it and sharing it with your doctor to have an informed discussion about your health and long-term weight loss strategy.

Some of you may believe you are using GLP-1 medications solely to manage your type 2 diabetes. While this may be true, it’s important to understand that the potential health risks still exist. The good news is that there’s a way to achieve better health and effectively manage pre-diabetes or type 2 diabetes through a “food as medicine” approach that addresses the root causes of your condition.

Please share this article with anyone you care about who is currently taking or considering these medications. It’s essential to be fully informed about the potential outcomes and make the best decisions for your health.

Thank you for taking the time to read this. If you have any questions or are interested in exploring healthier weight loss options, my contact information is provided at the bottom of the article.

Losing weight can be tough, and people try all sorts of methods. Some severely cut calories, while others take medications like Ozempic and Wegovy, known as GLP-1 agonists. But what if these methods have more in common than people think? Let’s compare what we know from the Minnesota Starvation Experiment with GLP-1 medications and uncover the hard truth about what happens to your body.

The Minnesota Starvation Experiment

During World War II, scientists conducted the Minnesota Starvation Experiment to understand what happens when people eat far fewer calories than they need. Thirty-six healthy men volunteered to eat about half their normal calories for six months.

The men lost a lot of weight, but here’s the shocking part: 40% of the weight lost came from muscle, not fat. Their metabolism—the way their body burns energy—slowed down drastically, putting them in starvation mode.

The men experienced major health problems, including:

• • Hair loss
  • Nausea
  • Dizziness
  • Paleness
  • Feeling cold all the time
  • Extreme fatigue
  • Obsessive thoughts about food

After the study ended, most of the men regained all the weight—and more. Their bodies stored fat to protect them from future starvation, a natural survival response.

GLP-1 Medications Like Ozempic and Wegovy

Now let’s look at GLP-1 medications, which have become a popular tool for weight loss. These medications work by suppressing appetite, so people eat much less. While this may feel like a shortcut, the effects on the body are eerily like the starvation mode seen in the Minnesota study.

Here’s what happens with GLP-1 medications:

• • 40% of the weight lost is muscle, not fat.
  • Metabolism slows down, just like in starvation mode.
  • People report similar side effects, including hair loss, nausea, dizziness, paleness, fatigue, and weakness.

Some people think GLP-1 medications are different because they don’t feel hungry while losing weight. But the body doesn’t care whether you feel hungry or not. When you eat too little, your body reacts the same way: it burns muscle, slows your metabolism, and tries to protect itself.

Can You Gain Back the Muscle You Lost?

Some people say, “I’ll use GLP-1 medications to lose weight now, and then I’ll start working out to gain back the muscle I lost.” While this might sound like a smart plan, the reality isn’t so simple—especially for people over 40.

When you’re young, around 25 years old, it’s easier to build back muscle after losing it. But as you age, your ability to regain muscle becomes much harder. After 40, your body naturally loses muscle every year unless you work hard to maintain it. Trying to rebuild muscle lost during weight loss is a serious uphill battle—and for many, it’s not realistic.

Losing muscle doesn’t just make it harder to stay active; it also slows your metabolism permanently. This makes keeping the weight off even more challenging. So, while the idea of “losing weight now and rebuilding later” might work for a healthy 25-year-old, it’s a risky gamble for anyone older.

The Hard Truth

We’ve known since the Minnesota Starvation Experiment that forcing the body into starvation mode—whether by extreme calorie restriction or using GLP-1 medications—leads to muscle loss, a slower metabolism, and long-term health risks. The medical industry now approves medications that essentially do the same thing, just without the feelings of hunger.

While it may feel like an easier solution, the results are the same:

• • Muscle loss that’s difficult (or impossible) to regain, especially over 40.
  • Side effects like hair loss, nausea, and dizziness.
  • A slowed metabolism that makes it harder to keep the weight off.

This quick-fix approach isn’t just unsustainable—it can have lasting consequences for your health.

A Smarter Way to Lose Weight

The best way to lose weight is to avoid starvation mode altogether. You can:

• • Eat balanced meals with enough protein to preserve muscle.
  • Exercise regularly to maintain strength and boost metabolism.
  • Lose weight slowly and steadily to ensure you lose fat—not muscle.
