SPEAKIN’ OUT NEWS
HUNTSVILLE, Ala. — Across North Alabama, a quiet transformation is reshaping how residents approach health, weight loss, and long-term wellness. While high-profile medications like semaglutide and tirzepatide have dominated headlines, researchers at the University of Alabama at Birmingham (UAB) are drawing attention to a critical but often overlooked reality:
Losing weight is only part of the equation. Preserving muscle may be the key to staying healthy.
Beyond the Scale: The Muscle Loss Concern
As the use of GLP-1 weight-loss medications rises, so does concern among medical professionals about unintended consequences—particularly the loss of lean muscle mass.
Dr. Anath Shalev, director of the UAB Comprehensive Diabetes Center, has been studying the metabolic effects of these treatments. Research published in Diabetes, Obesity and Metabolism highlights both the promise and the limitations of current therapies.
“While these medications are highly effective for weight loss, they are not without challenges,” Shalev noted in UAB research findings, citing side effects such as nausea, high cost, and the potential for muscle loss alongside fat reduction.
Maintaining muscle is not just about strength—it plays a vital role in metabolism, mobility, and independence, particularly for older adults.
New Research, New Possibilities
UAB researchers are now exploring next-generation treatments aimed at improving outcomes. One area of focus involves targeting TXNIP (thioredoxin-interacting protein), a molecule linked to cellular stress and metabolic dysfunction.
Early-stage investigations into therapies designed to regulate this pathway aim to support weight loss while preserving muscle mass—an approach that could reshape how obesity and diabetes are treated in the future.
While these treatments are still under study, researchers say they represent a promising step toward more balanced and sustainable weight management.
Rethinking Protein: Old Guidelines No Longer Enough
Alongside pharmaceutical advances, nutrition experts are urging a shift in how people fuel their bodies—especially when losing weight.
Jamie Baum, a nutrition scientist at UAB, emphasizes that traditional protein recommendations may fall short for many adults.
“As we age, our bodies become less efficient at maintaining muscle,” Baum explains in UAB guidance. “Higher protein intake can help offset that loss, particularly during weight reduction.”
For many adults, that means increasing daily protein intake beyond the long-standing baseline of 0.8 grams per kilogram of body weight. Experts now suggest a range closer to 1.0 to 1.6 grams per kilogram, depending on age, activity level, and health goals.
For a 150-pound adult, that translates to approximately 68 to 109 grams of protein daily—a significant but manageable shift.
A Local Approach to Better Health
For families across Huntsville and the Tennessee Valley, the shift toward higher-protein nutrition doesn’t require expensive supplements or extreme diets.
Registered dietitians recommend simple, sustainable changes:
• Fill one-quarter of your plate with lean protein (chicken, fish, eggs, beans)
• Pair protein with fiber-rich vegetables and whole grains
• Focus on whole, minimally processed foods
Riley Bowen, a UAB dietitian, notes that maintaining muscle mass also improves how the body regulates blood sugar—an important factor in a region with high rates of diabetes and insulin resistance.
“Muscle helps the body use glucose more effectively,” Bowen explains. “Supporting muscle health supports overall metabolic health.”
