Study Suggests , Workout Intensity , Could Affect Appetite Control.br A new study published in 'Nature' attempts br to determine how some workouts can help br people control how much they eat.br 'The New York Times' reports that a team br of international scientists suggest a single molecule br produced while exercising can blunt hunger.br More of those molecules are produced br after strenuous workouts than in br light or moderate workouts.br The molecule, named lac-phe br by scientists, is a mix of lactate br and the amino acid phenylalanine. .br The results are fascinating and add br a new dimension to our thinking about br exercise and body-weight regulation, Richard Palmiter, Professor of biochemistry br at the University of Washington in Seattle, br via 'The New York Times'.br We always knew that our current menu br of molecules that appear to regulate br appetite and food intake, such as leptin, br ghrelin, etc., was incomplete and this new br metabolitesignaling molecule br is a potentially important addition to that list, Barry Braun, the executive director of the Human Performance Clinical Research Lab at Colorado State University in Fort Collins, via 'The New York Times'.br The 'NYT' points out that the study does not br determine how lac-phe might interact with br brain cells or how long its effect lingers. .br Jonathan Z. Long, a professor of pathology at Stanford University School of Medicine and senior author of the new study, suggests the findings make evolutionary sense.br If you’re sprinting from a rhino or some br other threat, the autonomic nervous system br yells at the brain to shut down digestion br and any other unneeded processes, Jonathan Z.
