          Hunger Games: Ghrelin and Brain Cells Dictate Feeding Behavior

          A new study illuminates how the hormone ghrelin, released when hungry, influences feeding behavior in mice. Ghrelin activates specific neurons in the amygdala, a region primarily studied in the context of fear and reward, prompting food consumption and producing sensations of hunger and satisfaction.

          Viewing Food Images Multiple Times Curbs Appetite

          Viewing images of the same food item multiple times can lead to a feeling of fullness. The study found that when participants viewed the same food picture 30 times, they subsequently chose smaller portion sizes compared to those who saw the image just three times.

          Exercise Heightens Brain’s Food Cue Reactivity

          Exercise appears to amplify the brain's response to food cues, a new study reports. The researchers observed that running increased the reactivity of certain brain regions linked to attention, anticipation of reward, and memory. These changes occurred independently of overall alterations in brain blood flow.

          Feeling Hungry? It Might Just Slow Aging

          The sensation of hunger itself may slow aging. Researchers discovered that flies induced to feel hungry, either through diet or brain stimulation, lived longer.

          New Pill Regulates Appetite by Modulating Ghrelin Release

          A new pill, called FLASH, has been developed to regulate appetite without drugs or invasive procedures. Researchers designed the pill to deliver electrical impulses to the stomach lining, modulating hunger-related gut hormones. The pill has been shown to affect the release of appetite hormone ghrelin in pig trials. FLASH could potentially treat various disorders related to metabolism and eating without pharmaceuticals or surgery. The researchers are now conducting additional preclinical testing and aim to start human trials within five years.

          Leptin Helps Hungry Mice Choose Sex Over Food

          When their brains are stimulated with leptin, an appetite-suppressing hormone, hungry mice prioritize mating and interacting with mice of the opposite gender over eating.
