When you go running 5 times a week do you lose weight more in the cold or the warm?

Answer 1

You will burn more calories being cold than being warm. The body has to burn calories to maintain body heat.

However, you are more likely to lose water weight from sweat running in warm weather. But water weight and actual fat burning is not the same. You probably want to burn fat rather than just lose water.

However, in burning fat the body is more likely to retain external fat in cold weather as insulation, so during cold weather the fat you lose is more likely to be the internal fat which surrounds your organs. So from a visual perspective you might not see much of a difference, but you will see a difference on the scales.

Answer 2

Don't know. Whether you lose weight depends on how long you run, period. The body doesn't start to burn fat until about 30 minutes of exercise.
