Strong Marriages May Rewire Brain–Gut Signals

Strong emotional support within marriage may help protect against obesity by altering how the brain and gut communicate. People in highly supportive marriages showed better control of food cravings, healthier gut metabolism, and higher levels of oxytocin, a hormone linked to bonding and appetite regulation.

Obesity Speeds Alzheimer’s Biomarker by Up to 95 Percent

New longitudinal research shows that Alzheimer’s disease blood biomarkers rise up to 95 percent faster in people with obesity than in those without. While baseline tests initially appeared lower due to blood dilution, long-term tracking revealed a significantly accelerated buildup of neurodegeneration and amyloid pathology.

Smelling Fatty Foods in Pregnancy May Raise Obesity Risk in Children

New research shows that exposure to the smell of fatty foods during pregnancy and early life can reprogram the developing brain and increase the risk of obesity and insulin resistance in adulthood. Even when mothers consumed a healthy low-fat diet, the presence of fatty food odors altered how offspring responded to high-fat foods later.

Young Adults With Obesity Show Early Signs of Brain Stress

New research shows that young adults with obesity already display biological patterns associated with liver stress, chronic inflammation, and early neural injury—changes typically seen in older adults with cognitive impairment. Participants with obesity also had unusually low blood choline levels, a nutrient critical for liver function, inflammation control, and long-term brain health.

Why Comfort Food Feels Like Medicine for People in Chronic Pain

A new study reveals that more than two-thirds of people living with chronic pain turn to comfort foods—especially chocolate—for emotional relief and distraction during flare-ups. Eating provides temporary pleasure and even mild pain relief, likely due to biological effects of high-calorie foods on the brain’s reward and pain systems.

Brain ‘Dial’ That Controls Urge to Eat Discovered

Researchers have uncovered a brain circuit in mice that acts as a “dial” for consumption, controlling the urge to eat sweets, fats, salt, and other foods. The circuit links the amygdala to the BNST, a region tied to feeding and reward.

Pre-Pregnancy Obesity Linked to Autism Risk

A new study reveals how maternal obesity before pregnancy can program autism-related behaviors in offspring through lasting epigenetic changes in egg cells. Using IVF and embryo transfer in mice, researchers isolated the pre-conception effects, finding altered DNA methylation patterns that disrupted genes such as Homer1.

Astrocytes in Obesity: Brain Cells That Control Metabolism & Cognition

A new study reveals that astrocytes, star-shaped brain cells in the striatum, are key players in how obesity alters brain function and metabolism. Researchers showed that manipulating astrocyte activity in obese mice improved their cognitive flexibility and metabolic regulation.

Tiny Brain Cell Cluster Found to Drive Obesity and Overeating

Scientists have identified a small, specialized group of neurons in the mouse brain that directly influence eating behavior and weight gain. These PNOC/NPY cells, found in the hypothalamus, increase food intake when activated and are also present in the human brain.

Acetate and Bacteria Team Up to Burn Fat

A new study reveals that acetate—when paired with specific gut bacteria—can significantly reduce fat and liver mass in both normal and obese mice. Researchers used a supplement called AceCel, which delivers acetate directly to the large intestine, promoting the growth of Bacteroides bacteria.
