Intermittent Fasting Slows Huntington's Disease Progression

A recent study from Oregon Health & Science University suggests that simply shifting the timing of meals could slow the progression of Huntington’s disease. Researchers found that aligning food intake with the body’s natural circadian rhythm—by restricting eating to a specific window each day—improved motor function and reduced the accumulation of toxic protein fragments in animal models of the disorder.

The team conducted a series of experiments on mice genetically engineered to develop Huntington’s disease. When the animals were fed only during the night, the period that corresponds to their active phase, they showed markedly better coordination, fewer seizures, and lower levels of mutant huntingtin protein in brain tissue compared with mice that ate throughout the day. The researchers attribute these benefits to enhanced metabolic regulation and reduced oxidative stress, both of which are thought to contribute to neuronal damage in the disease.

While the findings are preliminary and derived from pre‑clinical models, they point to a low‑risk, non‑pharmacologic strategy that could complement existing therapies. OHSU investigators are now planning early‑phase clinical trials to determine whether time‑restricted feeding can similarly benefit people living with Huntington’s disease.
