If
you're exercising to lose weight, you're more likely to feel full if
your workout routine features aerobic exercise over resistance
training, according to a study published in the
journal Metabolism.
In
the study, Australian researchers divided overweight, sedentary men
into three groups. One group did aerobic workouts three times a week
for 12 weeks, one did resistance training three times a week for 12
weeks and one, well, did nothing beyond continuing their sedentary
ways.
Before
and after the 12-week period, the researchers measured the subjects'
perceived hunger and fullness, as well as appetite-related hormones,
both when the subjects hadn't eaten for a while and immediately after
a liquid carbohydrate meal of about 300 calories.
Over
the course of the study, perceived hunger didn't change for any of
the groups. Put another way, they all reported having similar
appetites. But the ones who had gotten in the habit of regular
aerobic exercise reported that they felt fuller sooner than they had
at the beginning of the study. In contrast, the ones who had done 12
weeks of resistance training reported no change in how quickly they
felt full after a meal.
This
was true even though most of the appetite-related hormone levels
didn't change in either of the exercise groups during the study. The
one hormone level that did change, leptin, changed in both the
aerobic and resistance-training groups, so its change is unlikely to
explain the difference between the groups' feelings of fullness.As
a result of their findings, the researchers concluded:
Aerobic
exercise training is associated with an increase in satiety, while an
equivalent period of resistance training is not.
