Do Fevers Burn Fat?

I have been stricken, unfortunately, with this nasty little virus that carries a low grade fever. No other symptoms, just fever. Since I feel like shit and can’t work out I was thinking maybe the fever itself burns fat. Since much fat loss is associated with raising body temp, it makes sense. Now,I am not going to let the fever run amuck, it hurts to much to do that. It is just a curious question. Nevertheless, I hope the motherfucker breaks soon. I’d rather train…

I always seem to have lost a couple pounds and my abs seem more pronounced after I get over a cold.

Could be alot of water weight loss along with reduced appetite due to the cld/virus. I have noticed the same thing in the past. Since the weight returns very quickly (for me anyway) I doubt it is true fat loss as opposed to water/glycogen depletion.

Short answer is yes. Your metabolism generally raises 7% with every 1 degree of temp increase so a fever of 102.6 would raise the metabolism 28%. Of course usually you aren’t eating as much and maybe puking so that also “assists” in weight loss (and helps with the abs).

However you usually lose fat, glycogen, muscle and water so it is not all fat, and obviously strength and performance usually drop significantly.

I have to respond to this…

I am recovering from Pneumonia and I was carrying a 101-104 fever for a week. I lost a ton of weight went from 127lbs to 118. Yes my abs were more defined and I looked leaner overall.

Uhmm though this is not the way I wanted too lose fat. Not to mention I literally was eating popsicles and soup if I was lucky. Dehydration is a big factor too. But let’s talk about how much muscle I lost too…

Your body while recovering from surgery or illness will burn way more calories while in recovery or fighting illness.

Like I said though it sucks … get well soon!

This sucks and it won’t go away!! I think I might have to break down a go to the Dr. tonight so he can tell me I have a virus and I need to rest, which is actually not possible at this time.
