The Truth Behind the Ozempic Rumors: Mounjaro and Medical Necessity

The headline-grabbing question—whether Meghan Trainor used Ozempic—has a detailed and nuanced answer that she and her husband, Daryl Sabara, have openly shared. The short answer is no, she did not use Ozempic (semaglutide), but she did use a similar, and in some ways more powerful, class of medication called Mounjaro (tirzepatide).

Meghan Trainor revealed that her postpartum weight loss journey was not triggered by a desire to conform to Hollywood standards, but rather by a significant health scare. During her first pregnancy, she was diagnosed with gestational diabetes. [cite: 10 from previous search] This diagnosis served as a critical wake-up call, prompting her to make serious, lasting changes to her diet and lifestyle for the sake of her long-term health and her family.

Why Mounjaro, Not Ozempic?

The public often uses "Ozempic" as a blanket term for all the new weight-loss injections, but there is a key medical difference between the two most popular drugs, Ozempic (semaglutide) and Mounjaro (tirzepatide).

• Ozempic (Semaglutide): This is a GLP-1 (Glucagon-like peptide-1) receptor agonist. It works by mimicking a hormone that targets receptors in the brain to reduce appetite and slow down digestion.
• Mounjaro (Tirzepatide): This is a dual-action medication, acting as both a GLP-1 and a GIP (Glucose-dependent insulinotropic polypeptide) receptor agonist. By targeting two satiety hormones instead of just one, Mounjaro has, in clinical trials, often demonstrated a superior reduction in A1c (blood sugar) and greater overall weight loss compared to Ozempic.

In April 2025, Meghan and Daryl Sabara confirmed they had used a low-dose regimen of Mounjaro as a tool to aid their weight loss journey, which was strictly combined with a new diet and exercise plan. This distinction is vital, as it frames the medication as a medically-guided component of a comprehensive lifestyle overhaul, not a standalone "magic shot."

While the GLP-1 medication provided a kickstart and helped manage appetite, both Meghan and her trainer, Bella Maher, have stressed that the dramatic 60-pound transformation seen in her recent before-and-after photos is primarily the result of hard work in the gym and a complete change in nutritional habits.

1. The Power of Strength Training

The biggest shift in Meghan's fitness routine was moving away from traditional cardio and embracing strength training—or "lifting weights." She has repeatedly stated that this change has "changed her life," providing her with a boost in energy, strength, and confidence she hadn't experienced before. [cite: 9, 12 from previous search]

• Muscle Preservation: Her coach, Bella Maher, highlighted that strength training is crucial when using GLP-1 medications like Mounjaro. These drugs can cause a loss of both fat and muscle mass. Lifting weights ensures that the weight lost is predominantly fat, while preserving and building lean muscle mass, which is vital for long-term metabolism and overall health.
• Increased Energy: The singer noted that the muscle gains helped her feel stronger and more energetic, which is a key factor in keeping up with the demands of motherhood and her career.

2. The High-Protein Diet Mandate

Complementing her new workout regimen is a strict, high-protein diet. This nutritional strategy works hand-in-hand with strength training to support muscle growth and recovery, especially while on a GLP-1 medication that reduces overall food intake.

• Protein Goal: Trainor aims for a high intake of 100 grams of protein daily. This focus on macronutrients ensures she maintains satiety, minimizes muscle wasting, and provides the building blocks for the muscle she is working hard to gain.
• Husband's Support: Her husband, Daryl Sabara, has been a key figure in this journey, participating in the fitness and diet changes alongside her. This spousal support is a critical, yet often overlooked, element of successful long-term lifestyle changes.

3. A Focus on Mental and Physical Wellness

Meghan's journey is a testament to the idea that true transformation is holistic. The motivation for her lifestyle change stemmed from a medical need (gestational diabetes) and a desire for better mental and physical wellness, not just a smaller dress size. Her openness about using Mounjaro and the rigorous effort involved in her strength training routine provides a refreshing and honest counter-narrative to the often-simplistic "Ozempic" rumors in the media.

By prioritizing a high-protein diet, dedicating herself to lifting weights, and utilizing a doctor-prescribed GLP-1 tool, Meghan Trainor has achieved a health transformation that is both dramatic and sustainable, proving that there is no shortcut to a healthy lifestyle—only hard work, medical guidance, and unwavering dedication.
