Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
During the study, the subjects received standardized dietetic and behavioral advice for weight reduction therapy. All subjects were given a standard text for information and met with a behavioral psychologist who has expertise in obesity treatment at the baseline visit and at visits at weeks 4,8, and 12. Additionally, the subjects had brief contact with a member of the study team every 4 weeks to inquire about their adherence to study protocol, any difficulties they were experiencing, whether they were reading their text assignments, and to answer any additional questions.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Liraglutide
Saxenda initiated at 0.6mg S.C. daily for 1 week; subjects will return to the Clinical Research Unit (CRU) each week until an increase by 0.6 mg/day in weekly intervals to a dose of 3.0 mg/day is achieved. Once maintenance dose of 3.0 mg is achieved, subjects will return approximately every 4 weeks to obtain new supply of study medication.
Liraglutide
Initiate at 0.6mg S.C. daily for 1 week; subjects will return to the Clinical Research Unit (CRU) each week until an increase by 0.6mg/day in weekly intervals to a dose of 3.0 mg/day is achieved (\~4 weeks). Once maintenance dose of 3.0 mg is achieved, subjects will return approximately every 4 weeks to obtain new supply of study medication.
Placebo
Placebo initiated at 0.6mg S.C. daily for 1 week; subjects will return to the Clinical Research Unit (CRU) each week until an increase by 0.6 mg/day in weekly intervals to a dose of 3.0 mg/day is achieved. Once maintenance dose of 3.0 mg is achieved, subjects will return approximately every 4 weeks to obtain new supply of study medication.

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
* Subjects residing within 125 miles of Mayo Clinic in Rochester, Minnesota.
* Healthy individuals with no unstable psychiatric disease and not currently on treatment for cardiac, pulmonary, gastrointestinal, hepatic, renal, hematological, neurological, or endocrine (other than hyperglycemia type 2 diabetes mellitus on metformin) disorders.
* Women of childbearing potential will be using an effective form of contraception, and have negative pregnancy tests within 48 hours of enrolment and before each radiation exposure.
* Subjects must have the ability to provide informed consent before any trial-related activities.
Exclusion Criteria
* Abdominal surgery other than appendectomy, Caesarian section or tubal ligation.
* Positive history of chronic gastrointestinal diseases, systemic disease that could affect gastrointestinal motility, or use of medications that may alter gastrointestinal motility, appetite or absorption, e.g., orlistat.
* Patients with a personal or family history of medullary thyroid carcinoma or Multiple Endocrine Neoplasia-type 2.
* Patients with a personal history of pancreatitis (acute or chronic)
* Significant untreated psychiatric dysfunction based upon screening with the Hospital Anxiety and Depression Inventory, a self-administered alcoholism screening test (AUDIT-C), and the Questionnaire on Eating and Weight Patterns (binge eating disorders and bulimia). If such a dysfunction is identified by a Hospital Anxiety Depression (HAD) score \>8 or difficulties with substance or eating disorders, the participant will be excluded and given a referral letter to his/her primary care doctor for further appraisal and follow-up.
* Intake of medication, whether prescribed or over the counter (except multivitamins), within 7 days of the study. Exceptions are birth control pill, estrogen replacement therapy, thyroxin replacement therapy and any medication administered for co-morbidities as long as they do not alter gastrointestinal motility including gastric emptying (GE) and gastric accommodation. For example, statins for hyperlipidemia, diuretics, β-adrenergic blockers,Angiotensin Converting Enzyme (ACE) inhibitors and angiotensin antagonists for hypertension, and metformin for type 2 diabetes mellitus or prediabetes are permissible. In contrast, resin sequestrants for hyperlipidemia \[which may reduce GE and reduce appetite, α2-adrenergic agonists for hypertension, or other glucagon-like peptide-1 receptor agonists (GLP-1) receptor agonists (exenatide) or amylin analogs (pramlintide) are not permissible because they significantly affect GE and/or gastric accommodation.
* Hypersensitivity to the study medication, liraglutide.
