Cells Burn More Calories After Just One Bout of Moderate Aerobic Exercise, OSU Study Finds
In a recent study testing the effects of exercise on overall metabolism, researchers at Oregon State University found that even a single session of moderate aerobic exercise makes a difference in the cells of otherwise sedentary people. Mitochondria are the part of the cell responsible for the biological process of respiration, which turns fuels such as sugars and fats into … [Read more...]
Satiety factor Associated with prolonged exercise
A drug that helps us to eat less could help the more than 650 million people around the world who live with obesity. One of the emerging drug candidates that interest researchers is the hormone GDF15 that, when given to rodents, lowers their appetite and body weight. New research from the University of Copenhagen finds that the body produces large amounts GDF15 during extended … [Read more...]

A gut-to-brain circuit drives sugar preference and may explain sugar cravings
A little extra sugar can make us crave just about anything, from cookies to condiments to coffee smothered in whipped cream. But its sweetness doesn't fully explain our desire. Instead, new research shows this magic molecule has a back channel to the brain. Like other sweet-tasting things, sugar triggers specialized taste buds on the tongue. But it also switches on an … [Read more...]
