    Study finds Dopamine, Biological Clock link to Snacking, Overeating and Obesity

    A new study finds that the pleasure center of the brain and the brain’s biological clock are linked, and that high-calorie foods – which bring pleasure – disrupt normal feeding schedules, resulting in overconsumption.

    During the years 1976 through 1980, 15% of U.S. adults were obese. Today, about 40% of adults are obese. Another 33% are overweight.

    Coinciding with this increase in weight are ever-rising rates of heart disease, diabetes, cancer and health complications caused by obesity, such as hypertension...

    Dietary Iron Intake, equivalent to Heavy Red Meat consumption, Suppresses Leptin, a hormone that regulates Appetite

    Serum leptin and adipocyte leptin mRNA levels decrease with dietary iron...

    Serum leptin and adipocyte leptin mRNA levels decrease with dietary iron overload. (A) Iron levels measured by ferrozine-based colorimetric assay in mice fed low normal– and high-iron diet (n = 4 mice/group). (B) Tfrc mRNA levels quantified by qPCR and normalized to cyclophilin A in adipose tissue from mice fed different levels of dietary iron (n = 6 mice/group). (C) Serum leptin levels from the mice (n = 6 mice/group). (D) Intracellular leptin levels by Western blotting. Data are representative of 3 experiments with n = 4 per replicate. (E) Quantification of leptin protein levels from D normalized to tubulin (n = 4 mice/group). (F) Leptin mRNA levels quantified by qPCR and normalized to cyclophilin A in adipose tissue from mice fed different dietary iron (n = 6 mice/group)...
