Study summary

In non-alcoholic fatty liver disease (NAFLD), it is established that calorie restriction is the most essential dietary modification. The time-restricted diet is successful lowering total calorie consumption and insulin resistance, and is anticipated to be beneficial for patients with NAFLD. Therefore, this study aims to conduct a prospective study to determine the effect of time-restricted diet via a mobile application on the amount of intrahepatic fat and 10-year cardiovascular disease risk in patients with NAFLD.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Aged ≥ 19 years who are willing and able to complete all procedures
  • Hepatic steatosis by imaging (ultrasound, computed tomography, magnetic resonance imaging, and controlled attenuation parameter (≥260 dB/m))

Exclusion criteria

Exclusion Criteria:

  • (BMI) \<23
  • Other causes of chronic liver disease (, ), diseases or chronic cholestatic liver disease
  • Medications which cause liver disease or secondary hepatic steatosis (Tamoxifen, systemic , methotrexate, tetracycline, estrogens, valproic acid, and statin (registration is possible if statin is delivered in a consistent dosage within 12 weeks)
  • Significant alcohol intake (>210g/week for men, >140g/week for women)
  • Severe medical comorbidities (ischemic heart disease, 3rd degree atrioventricular block, , severe hypertension (blood pressure > 200/120 mmHg)
  • Psychiatric illnesses which limit ability to exercise safely
  • Diagnosed with diabetes on medication or insulin
  • Participation in a weight-loss program within 12 weeks
  • MRI
Terms in these criteria, in plain language(7)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

BMI (body mass index)

Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.

What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

Hepatitis B tests

Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.

Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.

Hepatitis C tests

Hepatitis C is a virus that infects the liver. An HCV antibody test can stay positive after an infection has cleared (and is occasionally positive without one); an HCV RNA test shows whether the virus is there now.

After treatment, hepatitis C counts as cured when HCV RNA is still undetectable 12 weeks or more after the treatment ended. Studies often accept people cured this way.

Autoimmune disease

A condition in which the immune system attacks the body’s own tissues, such as rheumatoid arthritis, lupus, psoriasis, type 1 diabetes or inflammatory bowel disease.

Immunotherapy studies often leave out active autoimmune disease, and some name exceptions, such as thyroid disease on replacement hormone. Check the exceptions this study lists.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

COPD

Chronic obstructive pulmonary disease: long-term lung disease that makes it hard to breathe out, including emphysema and chronic bronchitis.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

Study arms

  • Experimental
    Mobile application-supported both calorie restriction and time-restricted eating (mCR/TRE)

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Feb 2023 to primary completion in Jan 2024, 11 months.

Of 357 non-industry interventional studies with no phase under Non-alcoholic Fatty Liver Disease, half reached primary completion within 26 months of starting (the median), counting those still running; a quarter within 12 and three quarters within 51. This study's 11 months is below that.

Counting every sponsor, half of 385 studies reached it within 26 months; a quarter within 12 and three quarters within 50.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jan 24, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
