Time-restricted eating shows promise in slowing early Huntington’s disease progression
A 12-week pilot trial found that a daily six-to-eight-hour eating window was safe and associated with modest improvements in disease markers for early-stage Huntington’s patients.
A team from Oregon Health & Science University conducted a 12-week pilot study to test time-restricted eating in 20 adults with early-stage Huntington’s disease. Subjects limited food consumption to a six-to-eight-hour window each day, choosing schedules that fit their routines, and were instructed to maintain their usual caloric intake. The regimen was well tolerated, with participants following it on more than five days per one outlet, preserving body weight and lean muscle, and experiencing minimal side effects.
Clinical measures showed an average 0.5-point gain on the Unified Huntington's Disease Rating Scale, while neurofilament light—a marker of neuronal damage—fell by roughly 13 percent, contrary to the expected rise in untreated patients. Additional tests indicated enhanced cellular energy production. Although these early results are encouraging, experts stress that larger, randomized controlled trials are needed to confirm whether this simple dietary approach can truly slow disease progression.
Why it matters
If confirmed, a simple eating schedule could become a low-cost strategy to delay Huntington’s disease decline.
