Who cannot join

  • Diabetes mellitus
  • History or clinical manifestations of significant metabolic, hepatic, renal, hematological, pulmonary, cardiovascular, gastrointestinal, urological, neurological, or psychiatric disorders which in the opinion of the investigator would be expected to interfere with the study or increase risk to the subject.

  • History of a medical or psychological condition or social circumstances that would impair the subject's ability to participate reliably in the study.
  • Use within the last six months of medications that can result in significant weight gain or weight loss, including antipsychotics, selective serotonin reuptake inhibitors, anti-epileptic drugs, appetite-suppressants such as phentermine and sibutramine, and the lipase-inhibitor orlistat.

(If participant is taking calcium supplement > 3x/wk or more than 2 servings of dairy products per day, they are eligible to participate if they agree to stop for 1 month prior to study start date and for the duration of the study. Participants will similarly be asked to stop multivitamins as the majority of these supplements contain calcium.)

About this study

The objective of this study is to investigate the effect of calcium (Ca) and vitamin D (D) supplemented orange juice (OJ) on weight loss and visceral fat mass in overweight and obese adults.

Read the detailed description

The prevalence of obesity and levels of overweight is rising worldwide. In the United States, 63% of men and 55% of women are now overweight or obese. Recent epidemiological data and clinical trials have shown that a small daily increase in calcium or dairy products may result in annual losses in body weight and body fat. Data from clinical studies suggest that a 1000 mg per day increase in calcium intake is associated with an 8 kg difference in mean body weight and that calcium intake explains about 3% of the variance in body weight.

The objective of this study is to investigate the effect of calcium (Ca) and vitamin D (D) supplemented orange juice (OJ) on weight loss and visceral fat mass in overweight and obese adults.

Otherwise healthy overweight and obese men and women ages 18 to 65 years with a BMI between 25 and 35 kg/m2 will be randomized into one of the following experimental groups (36 in each group):

  1. Regular OJ: one 8 fluid oz serving three times/day (control)
  2. Regular OJ fortified with Calcium (350 mg/8 fluid oz serving) and Vitamin D3 (100 IU/8 fluid oz serving): one 8 fluid oz serving three times/day (treatment)

Subjects will receive either orange juice (OJ) (control) or OJ fortified with calcium and vitamin D3 (treatment) for 16 weeks. The study will involve 6 outpatient study visits to the study center.

Primary endpoint: Change in body weight after 16 weeks Secondary endpoint: Visceral fat change after 16 weeks as measured by single slice CT scan

Questions about this trial

What is this clinical trial studying?

A study testing Orange Juice fortified with Calcium and Vitamin D, Orange juice without Ca or VitD and Nutritional Counseling in people with Obesity and Overweight, run by Massachusetts General Hospital at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 9 inclusion and 10 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 1 Jun 2011. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change in body weight (time frame: Baseline and 16 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01363115, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 1 Jun 2011.
