• Portion Control: Mindful eating and portion control became a vital aspect of her daily routine to manage her caloric intake effectively.
• GLP-1 Medication: In April 2025, Meghan and Daryl Sabara confirmed they were using the GLP-1 medication Mounjaro as a tool to aid their weight loss, combined with their strict diet and exercise plan.

The Strength Training & Fitness Routine

Unlike many celebrity weight loss stories that focus on cardio, Meghan’s physical transformation is largely due to her commitment to strength training.

• Strength Training: She works out three times a week, focusing on weight lifting and building muscle mass.
• Training Partner: Her husband, Daryl Sabara, is her frequent workout partner, providing motivation and accountability.
• Focus on Muscle: Meghan has publicly stated she is "trying to grow my butt back" after the weight loss, indicating a focus on specific muscle groups and body sculpting rather than just scale weight.
• Trainer Support: Working closely with her personal trainer, Bella Maher, ensures her workouts are effective, safe, and tailored to her goals.

The Lasting Impact on Body Image and Mental Health

Meghan Trainor's journey is a powerful narrative about how physical health and mental well-being are deeply interconnected. While she was a champion of the "All About That Bass" message, her weight loss has brought a new level of confidence and self-acceptance.

Her openness about using medication like Mounjaro alongside diet and exercise is part of a broader conversation about health tools and destigmatizing weight management. By sharing her "before-and-after" photos and details of her regimen, she provides a realistic and motivational blueprint for other new mothers and individuals facing similar health challenges.

Ultimately, Meghan Trainor's 60-pound transformation is not a flash-in-the-pan diet but a sustainable, holistic lifestyle overhaul driven by the most important role in her life: being a healthy mother to her two sons. This commitment to long-term health is what makes her glow-up so inspiring to millions of fans.
