Time-restricted eating slows early Huntington's disease, OHSU study finds

A 12-week pilot trial shows intermittent fasting may reduce neurodegeneration markers without causing weight loss.

What to know

  • A 12-week pilot study found time-restricted eating (6-8 hour daily window) safe and potentially beneficial for early-stage Huntington's disease, with no unintended weight loss.
  • Participants showed improvements in disease severity scores and a 13% reduction in neurofilament light, a biomarker of nerve cell damage that typically rises with disease progression.
  • The findings are the first from a clinical trial of this approach in Huntington's patients, but researchers emphasize larger trials are needed to confirm whether it slows disease progression.
  • Huntington's disease affects ~41,000 Americans with no approved treatments that slow progression; the study grew from earlier animal research suggesting intermittent fasting activates brain-protective cellular pathways.

Results are encouraging and warrant further investigation in larger trials.

    Lead researcher emphasizes need for larger trials despite encouraging pilot results

    Russell Wells told Newsweek that the findings are encouraging but larger clinical trials are needed to confirm whether time-restricted eating can actually slow disease progression, framing the approach as one that may help protect brain cells rather than as a proven treatment.

    “One of the most encouraging findings was that time-restricted eating appeared to reduce a key marker of neurodegeneration while remaining safe and sustainable for participants. The results suggest this simple dietary approach may help protect brain cells, but larger clinical trials are needed.”

    Study design addressed safety concerns about weight loss in Huntington's patients

    Researchers had initially been uncertain whether intermittent fasting would be safe because unintended weight loss is already a concern for many Huntington's patients. The 20-study participants were encouraged to maintain normal calorie intake, and researchers closely monitored weight throughout; participants maintained both body weight and lean muscle mass.

    “Weight loss is a major challenge for many people with Huntington's disease, so asking them to eat within a limited time window seemed counterintuitive. What was exciting about this study is that participants were able to maintain their weight while showing signs that the intervention may be positively affecting the disease itself.”

    Study shows time-restricted eating reduces neurodegeneration biomarker by 13 percent

    Blood levels of neurofilament light, a marker of nerve cell damage that typically rises in Huntington's disease, fell by an average of 13 percent in study participants. On the Unified Huntington's Disease Rating Scale, participants improved by an average of 0.5 points, compared to the typical annual decline of one point.

    OHSU study finds time-restricted eating safe and potentially beneficial in Huntington's disease

    Oregon Health & Science University researchers published findings from a 12-week pilot study in Nature Metabolism showing that people with early-stage Huntington's disease could safely follow intermittent fasting while limiting food to a 6-8 hour window daily. Participants maintained their weight and showed improvements in disease severity measures and cellular energy production.

    “This is the first time this approach has been formally studied in people with Huntington's disease. We found that participants were able to follow the eating schedule, maintain their weight and show encouraging improvements in clinical and biological measures.”
