41.   The metabolic rate in the mice increased, but there have been no apparent adverse side effects from the mutation.

42.   The researchers found no significant change in metabolic rate during hopping after the load was added.

43.   The plan that follows offers easy ways to retain and even build muscle mass, plus other strategies to speed your overall metabolic rate.

44.   The scientists were delighted to see that the model gave rise to three-quarter-power scaling between metabolic rate and body mass.

45.   The report found no increase in metabolic rate as a consequence of repeatedly gaining and losing weight, but it hinted at psychological drawbacks.

46.   The study defined as vigorous any activity that raised the metabolic rate to six or more times the rate at rest.

47.   They hoped to determine possible consequences to repeated weight loss and gain, like lower metabolic rate, higher risk of cardiovascular disease or diminished psychological health.

48.   Those with a slow metabolic rate -- one consequence of a thyroid insufficiency -- often complain that they gain weight merely from looking at food.

49.   To document this point, he examined the longevity of birds, which have very high metabolic rates.

50.   Too much leptin and an animal loses weight by eating less, increasing its metabolic rate, and moving about more.
