Neuroscientist warns rapid GLP-1 weight loss may force brain to consume its own tissue
Dr. Tommy Wood, a University of Washington neuroscientist, warns that rapid weight loss from GLP-1 medications like Ozempic and Wegovy can deprive the brain of essential energy. He explains that extreme caloric deficits may force the brain to consume its own white matter, similar to what happens during intense marathon running. While these drugs can improve cognitive health by lowering blood pressure and blood sugar in obese patients, severe under-eating risks long-term cognitive impairment. Wood advises pairing these medications with resistance training and ensuring adequate intake of neuro-nutrients like omega-3s, iron, and B vitamins to protect brain function.
