About this study

Official title: Comparison at Overweight Between Those Who Receive Feedback Concerning Their Metabolic Profile or Not During an Intervention With Modified Starch- and Sucrosereduced Diet (SSRD)

The investigators have previously found that a starch- and sucrosereduced diet (SSRD) has led decreased gastrointestinal symptoms in patients with irritabel bowel syndrome (IBS). At the same time, investigators found that the weight was reduced and the nutrient intake was improved with a more favorable metabolic profile. However, it is a challenge to change lifestyle, and most persons fail to keep on with an improved diet for a long time. Investigators therefore now want to conduct a clinical trial with SSRD in overweight/obesity for 3 months. Persons with a BMI >25 kg/m2 will be included. To examine whether a feedback about improved metabolic profile enhances the compliance, participants will be randomized to be informed or not about the metabolic profile after the 6-week visit. Investigator´s hypothesis is that information about the improvement in the metabolic profile should increase the motivation and compliance in the patients, and thereby render better effects.

Read the detailed description

Patients with overweight or obesity will be recrutied to this open-label, randomized clinical trial. All participants will be informed about the starch- and sucrosereduced diet (SSRD). The diet will be continued for 3 months, with a physical visit with completion of study questionnaires, blood and feces sampling and measurements of anthropometry at baseline, after 6 weeks and 3 months. Thereafter, participants are free to eat whatever they want, but will be examined again after 1 year. Participants will be randomized to whether participants should be informed or not about the metabolic profile measured at week 6. Participants who are randomized to get information about the metabolic profile, will be called when the blood samples have been analysed, and informed about the changes in metabolic and nutrient results between baseline and 6 weeks. The investigators will then evaluate whether participants who were randomized to get information about their blood samples after 6 weeks, will have better compliance to the diet, and thereby have better effect on weight reduction and metabolic profiles. At the blood sampling after 3 months, all participants will be informed about their metabolic profiles. It is also of interest to study the effect at follow-up after 1 year, to see whether participants who were informed at 6 weeks differ from participants who were not.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change from Baseline in the Mean weight at 3 Months.

    All participants are instructed to eat a starch- and sucrosereduced diet (SSRD) during 3 months. Physical meetings are scheduled at baseline, week 6, month 3 and after 1 year, where weight (kg) is measured. Half of the participants are randomized to receive feedback on the metabloic profile after 6 weeks, and the other half will not get any feedback on their blood samples until after 3 months. The hypothesis is that those who recieve feedback on their metabolic profile in the middle of the intervention will be more motivated to follow the diet and be more compliant, which should result in better effects. The reduction in weight from baseline will be calculated. The main outcome is the weight change observed at 3 months.

    Measured: 1 year

  2. Change from Baseline in the Mean waist circumference at 3 Months

    All participants are instructed to eat a starch- and sucrosereduced diet (SSRD) during 3 months. Physical meetings are scheduled at baseline, week 6, month 3 and after 1 year, where waist circumferense (cm) is measured. Half of the participants are randomized to receive feedback on the metabloic profile after 6 weeks, and the other half will not get any feedback on their blood samples until after 3 months. The hypothesis is that those who recieve feedback on their metabolic profile in the middle of the intervention will be more motivated to follow the diet and be more compliant, which should result in better effects. The reduction in waist circumference from baseline will be calculated. The main outcome is the change observed at 3 months.

    Measured: 1 year

  3. Change from Baseline in the body mass composition at 3 Months

    All participants are instructed to eat a starch- and sucrosereduced diet (SSRD) during 3 months. Physical meetings are scheduled at baseline, week 6, month 3 and after 1 year, body mass composition is measured. Half of the participants are randomized to receive feedback on the metabloic profile after 6 weeks, and the other half will not get any feedback on their blood samples until after 3 months. The hypothesis is that those who recieve feedback on their metabolic profile in the middle of the intervention will be more motivated to follow the diet and be more compliant, which should result in better effects. The reduction in fat mass from baseline will be calculated. The main outcome is the change observed at 3 months.

    Measured: 1 year

The record says: opening soon, as of the sponsor's last update on 29 Apr 2026. Status can change between updates, so confirm with the study contact before making plans.

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.

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

Contact Bodil Ohlsson, Professor (+46 040 33 23 23, bodil.ohlsson@med.lu.se), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change from Baseline in the Mean weight at 3 Months. (time frame: 1 year). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 29 Apr 2026.
