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

According to Dr. Long, the findings
suggest that « intensity matters”
for exercise and appetite control
