Preliminary Why this matters to you Expert discussion

Early or partial results. Treat as a signal, not a conclusion.

AI Summary

This is a registered interventional trial comparing 12 months of time-restricted eating plus high-intensity interval training to control on fat mass in adults with overweight or obesity. The study is actively recruiting but results are not yet available in this registry record. No clinical evidence can be drawn at present.

What was studied

Interventional, Randomized, Parallel, Open label, Treatment purpose. Overweight and Obesity; age from 18 Years; to 50 Years. Intervention: Time-restricted eating and high-intensity interval training. Compared with: Control — No Intervention. n = 100. 1 site: Norway.

Key findings

Safety

Safety was not reported in the material analysed. Check the source before drawing any conclusion about harm.

Who this may help

The source did not state who this applies to in practice.

Plain-language summary

This is an active trial registration with no results posted; the study design and planned endpoints are sound but the evidence base does not yet exist.

Caveats

No results are reported in this registry record; the study is ongoing with recruitment status ACTIVE_NOT_RECRUITING.
Sample size justification not provided in registry entry.
Blinding status, allocation concealment method, and detailed eligibility criteria not specified in this registry abstract.
Effect sizes, p-values, and comparative outcomes between intervention and control groups not yet available.

Evidence assessment

Graded across the dimensions that decide whether you should act, each from what the source actually supports. There is no single score, and where a dimension was not assessed it says so.

Study design

moderate

Randomized controlled trial with intervention and control groups planned.

Directness

strong

Primary outcome is total fat mass, a direct measure of metabolic health in overweight/obesity.

Consistency

insufficient

No results reported; consistency cannot be assessed from registry record alone.

Risk of bias

insufficient

Study conduct not yet complete; blinding, allocation concealment, and completion rates unknown.

Sample adequacy

limited

Planned enrollment 100 participants; adequacy for primary outcome not justified in registry.

What is missing. This record has no key findings. That is a gap in the analysis, not a judgement about the study.

Source abstract

Registry record from ClinicalTrials.gov (NCT07036562). This is a study registration, not published results. Lead sponsor: Norwegian University of Science and Technology. Recruitment status: ACTIVE_NOT_RECRUITING. Phase: NA. Study type: INTERVENTIONAL. Enrollment: 100 participants (ESTIMATED). Conditions: Overweight and Obesity. Interventions: BEHAVIORAL: Time-restricted eating and high-intensity interval training. Primary outcome measures: Total fat mass , From baseline to after 12 months. Brief summary: This study will investigate the effects of 12 months periodised time-restricted eating combined with high-intensity interval training compared with a control group on fat mass in adults with overweight/obesity. Participants in the intervention group will complete the intervention remotely and will receive follow-up by telephone. Before randomisation, after 6 months and after 12 months, the investigators will measure the participants' body composition, physical fitness, fasting blood glucose and insulin, blood lipids, and blood pressure. Physical activity, diet, sleep quality, appetite, and adherence to the intervention will also be measured. Secondary sub-analyses of sex differences in the responses to the intervention will be performed.
