A study testing Alternating Energy Intake and Regular Energy Intake in people with Abdominal Obesity and Postprandial Lipemia, run by Maastricht University Medical Center at 1 site in Netherlands.

Unknown status

Status not confirmed. The sponsor has not verified this record for over two years, so it may be out of date.

Trial summary

Increasing evidence suggests that meal timing affects metabolic health. For example, intermittent fasting (IF) may have positive effects on plasma glucose and lipid levels, insulin sensitivity, and blood pressure. However, IF protocols often result in significant weight loss. Read more about this study

About this study

Official title: The Effect of Alternating Energy Intake Compared to Regular Energy Intake on the Fat Content in the Blood After a Meal in Abdominally Obese Adults

Increasing evidence suggests that meal timing affects metabolic health. For example, intermittent fasting (IF) may have positive effects on plasma glucose and lipid levels, insulin sensitivity, and blood pressure. However, IF protocols often result in significant weight loss. Therefore, it is not clear to what extent these beneficial metabolic effects are due to IF or to weight loss. Although the effect of IF independent of weight loss has been studied, daily energy intake in those studies did not differ between the days. Therefore, the investigators aim to examine the effect of alternating energy intake - i.e. standardised day-to-day fluctuations in energy intake - on metabolic health independent of weight loss.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Alternating Energy IntakeOther

    To alternate between caloric overconsumption (130% of usual total energy needs) and caloric underconsumption (70% of usual total energy needs) on a daily basis for 6 days/week followed by one ad libitum day for 4 weeks.

  • Regular Energy IntakeOther

    To consume the usual energy intake (100% of total energy needs) on a daily basis for 6 days/week, also followed by one ad libitum day for 4 weeks.

What is being measured

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

  1. Triacylglycerol area under the curve (AUC)

    The 4-hour AUC for triacylglycerol after consumption of a standardised mixed meal

    Measured: 4 hours

Secondary outcomes (10)
  1. Fasting glucose metabolism

    Fasting glucose metabolism (includes e.g. glucose and insulin concentrations)

    Measured: Baseline, week 2, and twice in week 4

  2. Fasting lipid metabolism

    Fasting serum lipid and lipoprotein profile

    Measured: Baseline, week 2, and twice in week 4

  3. Marker for postprandial lipid metabolism

    Marker for lipid metabolism includes triacylglycerol and will be measured after consumption of a standardised mixed meal

    Measured: 4 hour period after consumption of a standardised mixed meal

  4. Markers for postprandial glucose metabolism

    Markers for glucose metabolism include insulin and glucose and will be measured after consumption of a standardised mixed meal

    Measured: 4 hour period after consumption of a standardised mixed meal

  5. 24-hour glucose levels

    The total area under the curve (tAUC) for 24-hour glucose as measured with a continuous glucose sensor

    Measured: 24 hours

  6. Day-time glucose levels

    The tAUC for day-time glucose (07:00 - 22:00 h) as measured with a continuous glucose sensor

    Measured: From 07:00 to 22:00 (15 hours)

  7. Night-time glucose levels

    The tAUC for night-time glucose (22:01 - 06:59 h) as measured with a continuous glucose sensor

    Measured: From 22:01 to 06:59 (8 hours and 58 min)

  8. Glucose levels after main meal consumption

    The tAUC for glucose during 2 hours after main meal consumption (breakfast, lunch and dinner) as measured with a continuous glucose sensor.

    Measured: 2 hours

  9. The mean amplitude of glycemic excursions (MAGE)

    MAGE as parameter for the assessment of glycemic variability.

    Measured: 24 hours

  10. Continuous overall net glycemic action (CONGA)

    CONGA to assess intraday glucose variability within predetermined time windows -> 1-hour interval (CONGA-1), 2-hour interval (CONGA-2), and 4-hour interval (CONGA-4).

    Measured: 1 hour, 2 hours, and 4 hours

Questions about this trial

What is this clinical trial studying?

A study testing Alternating Energy Intake and Regular Energy Intake in people with Abdominal Obesity and Postprandial Lipemia, run by Maastricht University Medical Center at 1 site in Netherlands.

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 12 inclusion and 15 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: status not confirmed, as of the sponsor's last update on 26 Aug 2022. 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 Netherlands. 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?

Results are not available in the source record.

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

Contact Maite M. Schroor, MSc. (+31433884258, maite.schroor@maastrichtuniversity.nl), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Triacylglycerol area under the curve (AUC) (time frame: 4 hours). 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 26 Aug 2022.
