Does having a fever increase metabolism? Fevers have a totally different reason for needing to be “fed.” When you have a fever, it's your body's attempt to overcome the virus. This
increased heat causes an increase in metabolism
, which in turn increases calories burned.
Does a fever raise metabolic rate?
The higher body temperature during a fever is kept stable, and the body prevents it from moving either up or down. Higher body temperatures are energetically costly in terms of calories expended,
about an extra 10 to 12.5% increase in metabolic rate per degree fever centigrade
.
How many extra calories does a fever burn?
5 degree Celsius increase in body temperature, your basal metabolic rate increases by around 7 percent. Half a degree Celsius translates to just under a degree Fahrenheit, meaning your caloric needs could hypothetically increase by
14 percent or more

Does the flu speed up your metabolism?
Fever is part of the immune system's attempt to beat the bugs. It raises body temperature, which
increases metabolism
and results in more calories burned; for each degree of temperature rise, the energy demand increases further. So taking in calories becomes important.
