GLP-1s for Weight Loss: Are They Right for You? Expert Explains Body Composition Testing (2026)

Imagine a world where weight loss is not just about the numbers you see on the scale, but rather about understanding your body’s unique composition. This is the core message being shared by obesity expert Dr. Rocio Salas-Whalen, M.D., in her recent insights on GLP-1 medications. While these drugs have gained popularity and are increasingly accessible, determining whether they are right for you involves more than just a simple decision—it requires a deep dive into your individual health profile.

Some experts argue that GLP-1 medications could be beneficial for nearly everyone, yet others caution that the choice to use these diabetes and weight-loss drugs should hinge on a person's health history and potential risks. So, what’s the best way to figure out if GLP-1s are appropriate for you?

In an engaging interview with Fox News Digital, Dr. Salas-Whalen emphasized the importance of body composition testing as a key tool in this decision-making process. Often, individuals equate success with the number displayed on their scales, but this figure does not provide a complete picture of one’s health status. According to Dr. Salas-Whalen, "Just because you're losing weight doesn't necessarily mean you're becoming healthier. It all boils down to body composition."

The scale fails to reveal crucial details about the proportions of muscle and fat within the body. To gain a clearer understanding, many medical offices and some gyms utilize body composition machines. These sophisticated technologies measure three vital health markers:

  • Skeletal muscle mass
  • Body fat percentage
  • Visceral fat

Dr. Salas-Whalen explains that these metrics can help identify what aspects of your body may contribute to illness or support your overall health. She states, "I perform a body composition analysis on everyone who comes to see me. It's essential to evaluate your visceral fat, which is the fat surrounding your internal organs. This type of fat is inflammatory and can lead to increased insulin resistance and hyperinsulinemia, a condition characterized by excess insulin in the bloodstream."

Furthermore, she notes the significance of understanding your body fat percentage, ideally aiming for 28% or below for women and 20% or lower for men. This approach emphasizes that merely focusing on weight loss is insufficient; the focus should be on achieving a healthy body composition.

Skeletal muscle mass is another critical element of health that reflects the muscle developed through proper nutrition and exercise. "Muscle serves as an anti-inflammatory organ," Dr. Salas-Whalen points out. "It plays a vital role in reducing insulin resistance and utilizes about 80% of your glucose supply."

Ultimately, the goal of weight loss should extend beyond simply shedding pounds; it should involve a transformation of body composition. Dr. Salas-Whalen warns against indiscriminately prescribing GLP-1 medications, urging caution and professional guidance before making such decisions.

She stresses that those with an optimal body composition can enjoy similar health benefits without needing medication. "If you maintain a healthy body composition, you’re likely reaping the rewards that someone taking GLP-1 would experience," she explains. "It's unsafe to use a medication without a legitimate need."

Understanding your body composition is crucial, as the results can be eye-opening, according to Dr. Salas-Whalen. She acknowledges, "Every individual's journey is unique. However, most people are likely to need this treatment rather than not, and many could derive significant benefits from GLP-1 medications."

The World Health Organization has conditionally endorsed the long-term use of GLP-1 therapies for adults with obesity (defined as a BMI of 30 or above) as part of comprehensive obesity management. However, it does not advocate for these medications to be used universally without consideration of individual health conditions.

This conversation raises vital questions: Do you believe that weight loss should be solely based on the scale? How important do you think body composition is in the weight-loss journey? Share your thoughts in the comments!
