Obesity shaped Anna Olson's earliest notions of herself, when she saw a photo and thought, "Oh, I look different than the other kids." Olson's obesity began in toddlerhood, ran in her family, and left her with a chronic hunger hard to satiate. Dozens of diet, drug and exercise regimens didn't work, and advice from doctors was always the same: Eat less.
A recent study published in Biological Psychiatry identified a distinct subtype of psychiatric illness marked by brain inflammation, one that cuts across traditional diagnoses and may explain why standard treatments fail for some people (Tang et al., 2025).This new brain imaging study offers an interesting clue. It turns out that across different psychiatric disorders, some people show clear signs of brain inflammation, visible on scans and confirmed through immune system tests.
A group of scientists monitored 92 people with diabetes in Japan during their first year of treatment with weight-loss drugs and discovered that the patient's psychology can affect the success of these therapies. People who overate at the sight or smell of tasty food were more likely to respond well to the drugs over the long term, while those who overate for emotional reasons were less likely to do so.
You simply referenced a body mass index (BMI) table and found the weight that placed you in the "green" 18.5-24.9 BMI range (BMI values of 25.0-29.9 represented "overweight" and values of 30.0+ represented "obesity"). Coined by the famous nutrition researcher, Dr. Ancel Keys, in the 1970's, the BMI was a ratio of a person's weight versus their height (technically weight (kilograms) / [height (meters) 2].
Factors like obesity, high cholesterol, and alcohol intake, often seen as harmful, may predict better survival in patients developing cancer or cardiovascular disease, highlighting the complexity of health and wellness.
The future of medicine will be personalized, taking patients' specific medical history into account when prescribing care. Hand-tailored treatment plans are especially crucial for issues as nuanced as obesity.
The transformation in medicine driven by personalized gene therapies promises cures for many diseases, including cancer, diabetes, and autoimmune conditions, but widespread application may take decades.
