Exploring Adults’ Experiences with Tirzepatide for Weight Loss: A Mixed-Methods Study
Highlights
- Among 120 adults (mean age 42 ± 13 years; 50.8% male), 91.7% reported weight loss after initiating tirzepatide.
- Average Weight Efficacy Lifestyle (WEL) total score was 91 ± 34 (0–180 scale); higher WEL was observed in females, employed participants, those with coverage, and early in treatment.
- Interviews (n = 15) described high satisfaction with weight loss, better sleep/energy/mood, and mostly mild/transient gastrointestinal effects.
- Findings support pairing pharmacotherapy with behavioral support and addressing affordability/coverage to sustain benefits.
- Findings support the integration of behavioral support alongside tirzepatide pharmacotherapy and highlight the importance of treatment affordability and coverage. Prospective longitudinal studies are warranted to assess the durability of self-efficacy and health outcomes and to test strategies that optimize adherence and equitable access.

Principal Findings in Context
- Pair tirzepatide with structured behavioral support targeting hedonic cues (parties, cravings, high-calorie availability) and negative affect (stress, loneliness).
- Plan adherence supports at the 1–6-month mark (digital check-ins, skills refreshers, dose-escalation side effect troubleshooting).
- Address affordability and coverage barriers to mitigate financial stress that may undermine persistence.
- Track patient-reported outcomes (sleep, mood, energy, social functioning) alongside weight and metabolic markers.
