The purpose of this study is to assess the effects on placebo-corrected change from baseline QT interval corrected for individual heart rate (QTcI) of JNJ-64565111 close to steady state on Day 26 and on electrocardiogram morphology at supratherapeutic exposures in otherwise healthy overweight/obese adults after 4 weeks of treatment with JNJ 64565111 administered subcutaneously once weekly.

| Placebo-Corrected Change from Baseline in QT Interval Corrected for Individual Heart Rate (QTcI) on Day 26 Time-Matched Time Points | Placebo-corrected change from baseline in QT interval corrected for individual heart rate (QTcI) on day 26 time-matched time points will be determined. The mean change from baseline in QTcI for participants who receive placebo will be subtracted from the mean change from baseline in QTcI for participants on JNJ-64565111 at the same time point to generate placebo-corrected change from baseline in QTcI, which will be presented. | Baseline and Day 26 |
| Change from Time-Matched Baseline in QTc Interval | The QT interval corrected for heart rate (QTc interval) using Fridericia method will be measured by electrocardiograms (ECG). | Up to Day 27 |
| Change from Time-Matched Baseline in Heart Rate (HR) | The HR will be measured by ECG. | Up to Day 27 |
| Change from Time-Matched Baseline in QRS Interval | The QRS Intervals will be measured by ECG. | Up to Day 27 |
| Change from Time-Matched Baseline in PR Interval | The PR intervals will be measured by ECG. | Up to Day 27 |
| Measure | Description | Time Frame |

| Cardiac Repolarization as Determined by Mean Change from Time-Matched Baseline in QT Interval Corrected for Individual HR (QTcI) on Day 5 | Mean change from time-matched baseline in QT interval corrected for individual HR (QTcI) on day 5 to determine the effect of JNJ-64565111 on cardiac repolarization. | Baseline and Day 5 |

| Cardiac Repolarization as Determined by Mean Change from Time-Matched Baseline in QT Interval Corrected For HR Using Fridericia's Formula (QTcF) on Day 5 and Day 26 |
Mean change from time-matched baseline in QT interval corrected for HR using Fridericia's formula (QTcF) will be assessed on day 5 and day 26 to determine the effect of JNJ-64565111 on cardiac repolarization. |
| Baseline, Day 5 and Day 26 |
| Maximum Observed Serum Concentration (Cmax) | Cmax is defined as the maximum observed serum analyte concentration. | Days 1, 5, 26 and 27 |
| Time to Reach Maximum Observed Serum Concentration (Tmax) | Tmax is defined as actual sampling time to reach maximum observed serum analyte concentration. | Days 1, 5, 26 and 27 |

| Number of Participants with Adverse Events as a Measure of Safety and Tolerability | An adverse event is any untoward medical event that occurs in a participant administered an investigational product, and it does not necessarily indicate only events with clear causal relationship with the relevant investigational product. | From signing of the informed consent form (ICF) to end of study (approximately 12 weeks) |
| QTcI Changes Evaluated Using ECG Assessments versus Serum Concentrations of JNJ-64565111 | QTcI changes evaluated using ECG assessments versus serum concentrations of JNJ-64565111 will be quantified. QTcI is a QT interval corrected for heart rate using individual-specific correction formula and QTcI changes will be quantified using a linear or nonlinear mixed effects modeling approach. | Up to Day 27 |
