Why You Can’t Say No to Snacks Even When Full

New EEG research reveals that your brain refuses to "switch off" its reward response to food, even after you’ve eaten until you’re full.

This shows a child surrounded by junk food.

Brain’s Developmental Switch May Shape Lifelong Obesity Risk

Is your weight gain pre-programmed? Scientists have discovered a developmental "fate-switch" in the brain that decides if you’ll be driven by hunger or fullness.

This shows a brain surrounded by faded foods, as though the foods represent distant memories.

Memory of Food: Brain Circuits Control Appetite Through Context

Forget the "willpower" myth, new research suggests that your past experiences are the real secret to appetite control. By identifying a hidden circuit that links memory to hunger, scientists have discovered how the brain uses your environment to decide when it's time to eat, and how a "glitch" in this system leads to overeating.

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.
