About the research

This study is an ancillary study to the RESIST trial, in which adults with obesity receive the weight-loss medication tirzepatide and are randomly assigned to a structured resistance training program or to usual care for 24 weeks.

RESIST-MIND explores whether resistance training during tirzepatide treatment is associated with changes in attention and concentration, food-related thoughts ("food noise") and food craving, fatigue, sleep quality, everyday functioning, work ability, and motivation for exercise. It also explores whether preserving muscle mass and strength during weight loss is related to these changes. Participants complete questionnaires and a computer-based attention test at the start (Week 0) and at the end (Week 24) of the RESIST treatment period. No additional visits, interventions, or biological samples are part of this ancillary study.

Read the full description

RESIST-MIND is a prospective, observational, monocentric ancillary study conducted at the TUM Klinikum, Munich, Germany. Active participation in the RESIST trial (protocol code RESIST-26-HAL-0150-I; EU CT number 2026-526200-69-00) is a prerequisite for enrolment. RESIST is a randomized, controlled, open-label Phase IV trial evaluating a structured resistance training program versus usual care in 150 adults with obesity treated with tirzepatide (Mounjaro®) over 24 weeks. RESIST-MIND involves no investigational medicinal product, no intervention, and no randomization. Assignment to resistance training or usual care occurs exclusively within the RESIST trial.

RESIST-MIND adds validated self-administered questionnaires (MFI-20, PSQI, WHODAS 2.0 12-item, FNQ, FCQ-T-reduced, SSK scale; WAI and WPAI in working participants only) and the electronic d2-R Test of Attention at the RESIST baseline visit (V1, Week 0) and end-of-treatment visit (V7, Week 24). Muscle, strength, body composition, anthropometric and patient-reported data are obtained from the RESIST trial database. All endpoints are exploratory and equally ranked, defined as change from V1 to V7. Between-group differences (resistance training vs. usual care) are estimated using linear models adjusted for baseline. Associations between changes in body composition and changes in the ancillary endpoints are examined across both groups using correlation and multiple linear regression. No formal power calculation or multiplicity adjustment is performed.

Treatment, groups and participation

The registry may describe treatments and study duration without a complete visit calendar. Ask the study team for the exact schedule, procedures, risks, costs and alternatives. Keep your usual care plan unless your treating clinician tells you otherwise.

Assignment: Not reported
Masking: Not reported

Resistance training + tirzepatide

RESIST participants randomized to the structured resistance training arm of the RESIST trial, receiving tirzepatide and individualized diet and physical activity counselling. Assignment occurs within RESIST, not within this ancillary study.

Behavioral: Structured resistance training · Drug: Tirzepatide

Usual care + tirzepatide

RESIST participants randomized to the usual care arm of the RESIST trial, receiving tirzepatide and individualized diet and physical activity counselling. Assignment occurs within RESIST, not within this ancillary study.

Drug: Tirzepatide

Structured resistance training BEHAVIORAL

Machine-based structured resistance training over 24 weeks (approx. 3 sessions per week), delivered within the RESIST trial (not part of this ancillary study). Progressive program with an acclimation phase (weeks 1-4) and a target phase (weeks 5-24; 8-12 repetitions at approx. 70-75% 1-RM, with additional eccentric overload from week 9). Sessions are intended to be fully supervised during the first 6 weeks whenever feasible, thereafter at least one supervised session after each interim visit; remaining sessions at the trial site or at partner fitness facilities.

Tirzepatide DRUG

Once-weekly subcutaneous injection over 24 weeks, starting at 2.5 mg/week and increased by 2.5 mg every 4 weeks as tolerated up to a maximum of 10 mg/week, in accordance with the SmPC. Administered within the RESIST trial (not part of this ancillary study).
