INTRODUCTION

In recent years, weight loss strategies in the United States have evolved significantly, blending advances in medical science with a renewed focus on lifestyle habits. While balanced diets and regular exercise remain the foundation of healthy weight management, new approaches—including medications and minimally invasive procedures—are reshaping the conversation.

GLP-1 Medications: Ozempic, Wegovy, and Beyond

One of the most notable trends is the increasing use of GLP-1 receptor agonists, a class of medications originally developed to treat type 2 diabetes. Drugs such as Ozempic (semaglutide) and Wegovy (a higher-dose version of semaglutide approved specifically for obesity) have gained widespread popularity.

These medications work by mimicking the action of the natural hormone GLP-1, which helps regulate blood sugar, slow gastric emptying, and reduce appetite. Clinical studies published in the New England Journal of Medicine and recognized by the U.S. Food and Drug Administration (FDA) show that semaglutide can lead to significant weight loss in individuals with obesity when combined with healthy lifestyle changes.

New Medications: Zepbound and Tirzepatide

More recently, Zepbound (tirzepatide) has entered the spotlight. Tirzepatide acts on both GLP-1 and GIP (glucose-dependent insulinotropic polypeptide) receptors, which may enhance weight loss effects compared to GLP-1 medications alone. Early clinical trial data suggest that patients using tirzepatide may achieve greater average weight reduction, positioning Zepbound as a strong alternative in this growing market.

Lifestyle Still Matters: Diet and Exercise

Despite the excitement around weight loss medications, health experts emphasize that no pill or injection replaces lifestyle choices. The World Health Organization (WHO) and Centers for Disease Control and Prevention (CDC) continue to highlight balanced nutrition and regular physical activity as the cornerstone of long-term health.

Common evidence-based recommendations include:

• Eating a diet rich in vegetables, fruits, lean proteins, and whole grains
• Reducing consumption of processed foods high in added sugars and saturated fats
• Engaging in at least 150 minutes of moderate-intensity exercise per week

When paired with medications, these habits improve outcomes and support sustainable results.

Endobariatric Procedures: A Middle Ground

For individuals seeking alternatives to both medications and traditional bariatric surgery, endobariatric procedures are gaining attention. These minimally invasive treatments, such as endoscopic sleeve gastroplasty, reduce stomach size using endoscopic tools without external incisions. Early evidence indicates they can lead to meaningful weight loss with lower risks compared to surgery, though long-term data are still being collected.

The Future of Weight Loss Approaches

As science advances, weight management is no longer seen as a one-size-fits-all journey. The U.S. market now offers a spectrum of options—ranging from FDA-approved medications to endoscopic procedures—while continuing to stress the importance of lifestyle modifications.

For patients and healthcare providers, the challenge lies in selecting the most effective and safe combination of treatments, tailored to individual health needs.

1. Semaglutide (Ozempic/Wegovy)

Once-Weekly Semaglutide in Adults with Overweight or Obesity – A double-blind, randomized, placebo-controlled clinical trial published in the New England Journal of Medicine. In adults with overweight or obesity, 2.4 mg of semaglutide weekly resulted in a mean weight reduction of -14.9%, versus -2.4% in the placebo group, over 68 weeks. PubMed

2. Tirzepatide (Zepbound/Mounjaro)

Tirzepatide Once Weekly for the Treatment of Obesity – A study in the New England Journal of Medicine reported that obese adults who received tirzepatide (10 mg or 15 mg weekly) experienced weight reductions of -19.5% and -20.9%, respectively. New England Journal of Medicine 

Tirzepatide as Compared with Semaglutide for the Treatment of... – A head-to-head comparison study in the New England Journal of Medicine, published about 3 months ago, showed that tirzepatide was superior to semaglutide in reducing weight and waist circumference over 72 weeks. New England Journal of Medicine

Zepbound beats Wegovy for weight loss in first head-to-head trial – AP News report stating that, in obese participants without diabetes, Zepbound (tirzepatide) led to an average weight loss of about 20% (?22.8 kg), versus 14% (?15 kg) with Wegovy (semaglutide). AP News

3. Long-Term Sustainability

Zepbound Helps Keep Weight Off for 3 Years – A study presented at the European Congress on Obesity highlights that tirzepatide (Zepbound) sustains weight loss for up to three years, with less than 5% weight regain in most participants. Verywell Health
