too cool temps in the winter

I just replaced my thermostat due to cool running temps, and terrible gas 
mileage.  Unfortunately, the gas mileage does not seem to have responded, 
like the running temp has.
However, If the T-stat is functioning,  doesn't it regulate temp by blocking 
coolant flow to the radiator?  So, how exactly  would blocking air flow to 
the radiator help?
