Weightless AI

Weightless AI brings Dr. Rocio Salas-Whalen's 16+ years of obesity medicine expertise directly to your GLP-1 journey.

Built by a board-certified obesity medicine physician, endocrinologist, and bestselling author of Weightless, Weightless AI helps you move beyond weight loss and focus on what matters most: body recomposition, metabolic health, and long-term success.

Most people only see the number on the scale. Weightless AI helps you understand what is happening beneath the surface by tracking body fat, muscle mass, visceral fat, and other key health metrics that can help you and your clinical team make more informed decisions.

HOW ACCESS WORKS Weightless AI requires a subscription to unlock its features for self-pay users. If you've been invited by a participating Weightless AI clinician, your clinic covers your access and the app is free for you — no purchase required. Everyone else can subscribe for full access directly in the app.

A subscription unlocks body composition insights, the AI health assistant, body scans, and progress tracking. Personalized care plans are available only to patients invited by a participating clinic.

BODY COMPOSITION INSIGHTS Weight loss is only part of the story.

Track changes in body fat percentage, skeletal muscle mass, visceral fat, and other important body composition metrics over time. Understand how your body is responding to treatment and focus on preserving muscle while improving overall health.

AI HEALTH ASSISTANT Get answers to your questions about GLP-1 medications, nutrition, exercise, sleep, stress management, and metabolic health.

Unlike general-purpose AI tools, Weightless AI is built around Dr. Salas-Whalen's clinical methodology and obesity medicine protocols. Your AI assistant understands your health profile and provides educational guidance tailored to your journey.

PERSONALIZED CARE PLANS Access your care plan anytime.

Your clinician can create and update personalized recommendations for medication, nutrition, protein intake, physical activity, and strength training so you always know your next step.

TRACK YOUR PROGRESS Monitor your results over time with easy-to-understand trends and insights.

See how your body composition evolves, stay engaged with your goals, and celebrate meaningful progress beyond the scale.

CONNECTED TO YOUR CLINICAL TEAM Weightless AI helps bridge the gap between appointments.

Your clinician can review your data, monitor your progress, and adjust your care plan as needed to support your health goals.

BUILT FOR GLP-1 CARE Whether you're taking semaglutide, tirzepatide, or another GLP-1-based therapy, Weightless AI was designed to support a more informed, personalized, and data-driven approach to obesity care.

IMPORTANT INFORMATION Weightless AI is intended for educational and informational purposes only. The AI assistant does not diagnose medical conditions, prescribe medications, provide medical advice, or recommend medication changes. Always consult your clinician regarding treatment decisions, side effects, medication concerns, or urgent health issues.

Your journey is more than weight loss.

Weightless AI helps you understand your body, stay connected to your care team, and build a healthier future with confidence.
