“The drug mimics GLP-1, a hormone that helps the pancreas release insulin and the brain regulate appetite. But certain cells in the heart, blood vessels, and other tissues also carry GLP-1 receptors, allowing them to respond to the same signal.”

“Together, these circulating molecules may carry information about the workout to cells elsewhere in the body. The fat cell experiment supports that possibility because the plasma of post-sprint blood activated groups of genes involved in responding to hormones, nutrients, and fuel use.”

“The circadian rhythm is the body’s 24-hour clock that modulates a wide array of physiological processes, including the production of hormones that regulate sleep, hunger, metabolism, and others, ultimately influencing body weight, performance, and susceptibility to disease.”

“Getting an adequate amount of quality sleep is increasingly recognized as vital for mental and physical health. Sleep deprivation can increase stress hormones associated with anxiety and depression and greater risk of chronic diseases like cardiovascular disease.”

“The researchers gave participants an injection of a radioactive marker called [11C]-raclopride that binds to dopamine receptors so they could measure dopamine-related brain activity during the scan. Participants also completed surveys to assess eating behavior and provided a blood sample for measurement of insulin and other hormones.”

“Exposure to ultraviolet (UV) light is critical for maintaining many aspects of human health. For example, compounds present in the skin react to UV light, initiating the production of vitamin D, a steroid hormone that participates in many physiological processes.”

“Found in both plants and fatty fish, they influence cell membrane integrity, affect the function of membrane-bound cellular receptors, and participate in pathways involved in the biosynthesis of hormones that regulate blood clotting, arterial function, and inflammation.”

“Compared to non-consumers, participants who consumed three or more 8-ounce servings of sugar-sweetened beverages per week experienced a 35 percent increased risk of death due to cancer and 28 percent increased risk of death due to any cause.”

“Biochemical changes included a 32 percent rise in plasma levels of brain-derived neurotrophic factor (BDNF), which supports neuron growth and connectivity, and a 52 percent reduction in leptin, a hormone tied to fat mass, appetite control and inflammation.”

“These cues help synchronize the body's 24-hour rhythms across many organs and tissues, including rhythms involved in blood pressure, blood sugar control, inflammation, hormone signaling, and cellular repair.”
