  • Weight loss success takes more than just willpower: Obese patients who are trying to lose weight need to understand that they’re up against a complex interaction between neurobehavioral processes and a saturated food environment, dietitians said.  Science is increasingly showing that this interaction is largely responsible for weight gain….Emphasizing this dietary dynamic may be more effective than simply instructing patients to eat less calorie-dense foods….shifting the emphasis away from poor personal choices to brain systems interacting with a ‘toxic’ food environment may improve outcomes while reducing stigma…”. (Kristina Fiore, MedPage Today)
  • Is a resting heart rate between 60 to 100 beats per minute normal? “The normal resting heart rate for an adult ranges from 60 to 100 beats per minute.  But some researchers believe it may be time to re-examine what’s considered normal.   Researchers have found that a resting pulse at the upper end of ‘normal’ may indicate a higher risk of stroke and heart disease.  Some have linked it to a greater risk of diabetes and obesity.”  You can lower your resting heart rate by stepping up cardio training.  The bottom line: “A resting heart rate about 80 beats a minute may be a red flag.” (Anahad O’Connor, NY Times)
  • FDA warns ‘Lazy Cakes’ are unsafe: “The FDA said it can seize the brownies if HBB continues to make and market them.  The federal agency said that it does not consider melatonin to be a safe food additive and that the brownies are ‘adulterated’ because they contain it.” (Associated Press)
  • Some exercise is better than none: “Turns out that might be true – people who do even a little regular exercise may have lower risk of heart disease than people who never leave the sofa.” You think? (LA Times)
