Researchers are testing whether feeding stroke patients on a schedule (8-12 hours daily) improves recovery better than continuous 24-hour feeding. According to Gram Research analysis, this TENET trial will randomly assign severely ill stroke patients to either time-restricted or continuous tube feeding and track their recovery over 90 days. The study aims to determine if respecting the body’s natural eating-fasting rhythm improves outcomes like mobility and independence after severe stroke.
Researchers are testing a new way to feed stroke patients in the hospital. Instead of feeding patients continuously through a tube 24 hours a day, they want to try feeding them only during daytime hours (8-12 hours) to match the body’s natural rhythm. According to Gram Research analysis, this approach may help patients recover better and reduce complications. The study will follow hundreds of severely ill stroke patients and track their recovery over 90 days to see if timed feeding works better than constant feeding.
Key Statistics
The TENET trial is a multicentre randomized controlled trial comparing time-restricted enteral nutrition (8-12 hours daily) to continuous 24-hour feeding in severe stroke patients, with 90-day follow-up to assess functional recovery outcomes.
Severe stroke patients enrolled in the TENET study must score 11 or higher on the National Institutes of Health Stroke Scale or 12 or lower on the Glasgow Coma Scale, indicating significant stroke severity requiring intensive care.
The TENET trial will track primary outcomes including functional recovery at 90 days, along with secondary measures of consciousness level, stroke severity, daily activity ability, ICU length of stay, and mortality rates at 28 and 90 days.
The Quick Take
- What they studied: Whether feeding stroke patients on a schedule (only during daytime) works better than feeding them continuously around the clock
- Who participated: Severely ill stroke patients in intensive care units who cannot eat normally and need feeding tubes. Patients must have significant stroke damage (high NIHSS scores or low consciousness levels)
- Key finding: This is a study design paper describing a trial that will test if time-restricted feeding (8-12 hours daily) improves recovery compared to 24-hour continuous feeding in severe stroke patients
- What it means for you: If results are positive, hospitals may change how they feed stroke patients in ICU, potentially improving recovery outcomes. However, results won’t be available until the trial completes
The Research Details
The TENET trial is a randomized controlled trial, which is the gold standard for testing medical treatments. Researchers will randomly assign severely ill stroke patients to one of two groups: one group receives food through a feeding tube continuously (24 hours a day), while the other group receives food only during daytime hours (8-12 hours). This design allows researchers to fairly compare which approach works better.
The study will take place at multiple hospitals and will follow patients for 90 days after their stroke. Researchers chose this approach because they noticed that continuous feeding disrupts the body’s natural daily rhythm (circadian rhythm), which normally includes periods of eating and fasting. The study aims to determine if respecting this natural rhythm improves recovery.
Patients will be tracked until they leave the ICU, stop needing feeding tubes, pass away, or 28 days of nutrition support have been provided—whichever comes first. This practical approach ensures the study captures real-world outcomes.
This research design is important because it directly tests a simple change that could benefit many stroke patients. Continuous feeding is standard practice, but it may interfere with the body’s natural biological clock. By using a randomized design, researchers can determine whether time-restricted feeding actually improves outcomes or if continuous feeding remains the better approach. The results could change how hospitals care for thousands of stroke patients annually.
This is a prospective study, meaning researchers will collect data as events happen rather than looking backward. It’s randomized, so patients are assigned by chance rather than by choice, which reduces bias. The study is registered in a clinical trial database (NCT06161948), which increases transparency and credibility. However, this paper describes the study plan, not actual results—the trial is still ongoing
What the Results Show
This paper presents the study design and rationale rather than actual results. The researchers will measure whether time-restricted feeding improves patient outcomes by looking at functional recovery at 90 days. The primary outcome is whether patients have poor functional recovery (measured by the modified Rankin scale score of 3 or higher), which indicates significant disability.
The study will also track secondary outcomes including consciousness levels, stroke severity scores, ability to perform daily activities, length of ICU stay, and survival rates at 28 and 90 days. Safety will be monitored throughout hospitalization to ensure neither feeding approach causes unexpected harm.
The study design includes a 90-day follow-up period, which is long enough to assess meaningful recovery differences between the two feeding approaches. This timeframe captures both immediate recovery and longer-term functional outcomes that matter to patients and families.
Beyond the main outcome, researchers will examine several other important measures: consciousness level improvements, stroke severity changes, ability to perform daily activities, and how long patients stay in the ICU. Mortality rates at 28 and 90 days will be tracked to ensure time-restricted feeding doesn’t increase death risk. All adverse events and serious complications during hospitalization will be documented to assess safety.
Current medical practice typically uses continuous enteral nutrition in ICU settings because it’s thought to provide steady nutrition and prevent complications. However, growing evidence suggests that continuous feeding disrupts the body’s natural circadian rhythm, which regulates many biological processes important for recovery. This study builds on research showing that time-restricted eating may benefit various health conditions by respecting the body’s natural feeding-fasting cycle. The TENET trial will be among the first to rigorously test this approach specifically in severe stroke patients.
This paper describes a planned study, so actual results aren’t yet available. The study is open-label, meaning patients and doctors know which feeding method is being used, which could influence outcomes. The exact sample size isn’t specified in this design paper. Results won’t be available for several years, and findings may only apply to severely ill stroke patients in ICU settings, not all stroke patients
The Bottom Line
This is a study design paper, not a completed trial, so no clinical recommendations can be made yet. Once results are available, hospitals may consider changing feeding practices for severe stroke patients if time-restricted nutrition proves safer and more effective. Current practice should continue until evidence supports a change. Confidence in any future recommendations will depend on the trial’s results.
Stroke patients and their families should care about this research because it could improve recovery outcomes. Hospital ICU staff and stroke specialists should follow this trial’s results. Healthcare administrators should monitor findings that could change standard feeding protocols. People at risk for stroke should be aware that research is advancing stroke care. This research doesn’t apply to people who can eat normally or have mild strokes.
The trial is currently enrolling patients and will continue until sufficient data is collected. Results likely won’t be published for 2-3 years. If positive, changes to hospital feeding protocols would take additional time to implement. Patients shouldn’t expect immediate changes to their care based on this study design announcement
Frequently Asked Questions
Is continuous feeding bad for stroke patients in the ICU?
Continuous 24-hour feeding may disrupt the body’s natural daily rhythm, which normally includes eating and fasting periods. The TENET trial will test whether time-restricted feeding (8-12 hours daily) improves recovery compared to continuous feeding in severe stroke patients.
How does time-restricted feeding help stroke recovery?
Researchers believe respecting the body’s natural circadian rhythm—the internal clock that regulates eating, sleeping, and other functions—may improve recovery. The TENET trial will measure whether limiting feeding to daytime hours (8-12 hours) produces better outcomes than continuous feeding.
When will we know if time-restricted feeding works for stroke patients?
The TENET trial is currently enrolling patients and testing this approach. Results likely won’t be published for 2-3 years. Once complete, findings will show whether hospitals should change how they feed severely ill stroke patients in intensive care.
Does this study apply to all stroke patients?
No, the TENET trial focuses specifically on severely ill stroke patients in ICU who cannot eat normally and require feeding tubes. Results may not apply to patients with mild strokes or those who can eat regular food.
What outcomes will the TENET trial measure?
The trial will measure functional recovery at 90 days, consciousness level, stroke severity, ability to perform daily activities, ICU length of stay, and survival rates. Safety will be monitored throughout hospitalization to ensure neither feeding approach causes harm.
