Inclusion criteria

* Healthy male or female adolescents, age 12 to 17 years (inclusive) at Screening, with a BMI that is greater than or equal to the United States-weighted mean of the 95th percentile based on age and sex with a body weight greater than 60 kilograms (kg). Participants with Type 2 diabetes mellitus (T2DM) may have a pre-existing or new diagnosis of T2DM. Participants with pre-existing T2DM should have prior documentation consistent with the diagnosis and/or be on active pharmacotherapy for T2DM. Participants with a new diagnosis of T2DM (ie, diagnosed at Screening) should be based on the 2016 American Diabetes Association (ADA) guidelines. The diagnostic criteria are met if a participant has unequivocal hyperglycemia (random plasma glucose ≥200 milligrams per deciliter (mg/dL) (11.1 millimoles per liter \[mmol/L\]) with classic symptoms of hyperglycemia or hyperglycemic crisis) OR any of the following criteria are observed and confirmed: * HbA1c ≥6.5% * fasting plasma glucose (FPG) ≥126 mg/dL (7.0 mmol/L) * 2-hour plasma glucose ≥200 mg/dL (11.1 mmol/L) by an oral glucose tolerance test (OGTT) All T2DM participants must have an HbA1c \<10% at Screening. If participants are being or need to be treated with antidiabetic agents, the T2DM treatment regimen must be stable for at least 3 months before randomization. A single rescreen is allowed following stabilization. Stable control refers to minimal dose changes to existing medications for glycemic control and no medications being initiated for glycemic control in the 3 months before randomization. Minimal changes are defined as a change without any change in dose frequency, no add-on or discontinuation of other antidiabetic agents and the participant has not been hospitalized due to hypo- or hyperglycemic events. * Participants and their families not planning to move away from the area for the duration of the study * Participants able and willing to comply with all aspects of the study, including a standardized, reduced calorie diet and an age appropriate, increased physical activity program * Participants considered in stable health in the opinion of the investigator * Caregivers or guardians meet the following requirements: * Able and willing to support and supervise study participation in the opinion of the investigator, including consideration of any existing physical, medical, or mental condition that prevents compliance with the protocol * Able and willing to personally comply with and execute all aspects of the study requirements for the caregivers or guardians

Exclusion criteria

* Clinically significant new illness within 1 month before randomization that may affect the participant's ability to fulfill the study requirements or significantly confound the assessments * Participants who cannot swallow investigational products * Participants with T2DM who have hypoglycemia unawareness * Any of the following findings on Screening echocardiography: * Aortic regurgitation mild or greater * Mitral regurgitation moderate or greater * Mitral or aortic valve stenosis greater than mild (ie, aortic stenosis: jet \>3.0 meters per second \[m/s\], mean gradient \>25 millimeters of mercury \[mmHg\], and aortic valve area \<1.5 centimeters squared \[cm\^2\]; mitral stenosis: mean gradient \>5 mmHg and mitral valve area \<1.5 cm\^2) * Systolic pulmonary artery pressure (SPAP) \>40 mmHg (and/or tricuspid regurgitation \[TR\] jet velocity \>2.9 m/s) In cases where an actual SPAP value is not measurable due to lack of adequate TR jet, the pulmonary flow acceleration time measured at the right ventricular outflow tract (RVOTAT) will be used to assess eligibility. Participants with a RVOTAT ≤100 milliseconds (msec) will be excluded, suggesting an elevated mean SPAP; eligibility for the those participants with RVOTAT between 100 and 120 msec will be determined based on combined assessment of the TR jet, septal motion, and right ventricular size. * Left ventricular ejection fraction \<45% * Intracardiac mass, tumor, or thrombus * Evidence of congenital heart disease * Clinically significant pericardial effusion (eg, moderate or larger or with hemodynamic compromise) * Significant renal or hepatic disease as evidenced by a serum creatinine greater than 1.5× upper limit of normal (ULN), serum transaminases greater than 3× ULN, or total bilirubin greater than 1.5× ULN in absence of Gilbert's syndrome * Any suicidal ideation with intent with or without a plan, at the time of or within 6 months of Screening, as indicated by answering Yes to questions 4 or 5 on the Suicidal Ideation section of the Columbia-Suicide Severity Rating Scale (C-SSRS) * Any suicidal behavior in the past based on the C-SSRS * Any history of anorexia or bulimia within 2 years before Screening, Attention Deficit Hyperactivity Disorder, any Diagnostic and Statistical Manual of Mental Disorders, 5th Edition depressive disorder, bipolar disorder, or schizophrenia * Known secondary causes (genetic, endocrine, or metabolic) for obesity (eg, Prader-Willi syndrome, Bardet Biedl syndrome, Down's Syndrome, untreated hypothyroidism, Cushing's syndrome, daily systemic corticosteroid exposure for longer than 30 days, history of significant exposure to corticosteroids for chronic illness during the past year; inhaled steroids will be allowed) * Use of other products intended for weight loss including prescription drugs, over-the-counter (OTC) drugs, and herbal preparations within 1 month before Screening * Use of any of the following medications: * Serotonergic drugs within 7 days (or 5 half-lives, whichever is longer) or monoamine oxidase inhibitors within 30 days before Randomization, including: * selective serotonin reuptake inhibitors * serotonin norepinephrine reuptake inhibitors * tricyclic antidepressants * bupropion * triptans * St. John's Wort * tryptophan * linezolid * dextromethorphan in any form (eg, OTC cold medicines) * lithium * tramadol * antipsychotics or other dopamine antagonists * Others * antiseizure medications including valproic acid, zonisamide, topiramate, and lamotrigine * oral steroids (topical and inhaled steroids are acceptable) * stimulant medications (eg, Ritalin, Concerta, Biphetamine, and Dexedrine) * benzodiazepines * Use of drugs known to increase the risk for cardiac valvulopathy within 6 months before Screening, including but not limited to pergolide, ergotamine, methysergide, and cabergoline * History or evidence of clinically significant disease (eg, malignancy; cardiac, respiratory, gastrointestinal, renal, or psychiatric disease) other than prediabetes (impaired fasting glucose or impaired glucose tolerance), type 2 diabetes treated with oral anti-diabetic agents (excluding sulfonylurea) or non-insulin injectable antidiabetic agents, obstructive sleep apnea, dyslipidemia, and nonalcoholic fatty liver disease * Use of Belviq XR within 6 months before Screening or hypersensitivity to Belviq XR or any of the excipients * Significant change in diet or level of physical activity within 1 month before dosing or change in weight of more than 5 kg within 3 months before Screening * Any use of a very-low-calorie (\<1000 calories/day) weight loss diet within 6 months before Screening * History of alcohol or drug dependence or abuse * Recreational drug use within 2 years before Screening * Known to be human immunodeficiency virus positive * Known to have active viral hepatitis (B or C) * Malignancy within 5 years before Screening * Unable to attend scheduled visits (eg, lack of transportation) or lack of a caregiver or guardian to supervise study participation * Special needs participants who are unable to comprehend study-related instructions (eg, mild to profound mental retardation \[intelligence quotient \<70\], moderate to severe cognitive developmental delay, pervasive development disorders, autism) * Ongoing epilepsy or other seizure disorder, or use of medications for a seizure disorder within 6 months of screening or any time between screening and randomization * Participants with a blood pressure in the 95th percentile or greater for age, sex, and height on 2 separate readings recorded on 2 separate days.
