Hey i'm just curious, do you burn more calories when you're sick? Usually I do 1 hour cardio 5 times a week and eat very strict and do weights about 6 times a week and have been maintaining my weight for the past month or so. However, for the past week ive been sick with a fever (coughing, sore throat, slight headaches and feeling heaps tired) so I haven't been doing any cardio at all, and along with that I have literally been eating double the calories of what I normally eat along with sleeping at least 9 and a half hours a night (usually sleep 7.5 - 8 hours a night) and I havent gained any weight at all, I even lost weight at one stage. Is this because I am sick? or is it because I have been following a strict program for a while now and the excess calories have basically just been like a refeed / recover week? or a bit of both? Has anyone else experienced anything similar to this when sick?

maybe someone more qualified can comment better then I can...
but wouldn't your body just borrow resources from other places? I mean by virtue of being sick you're going to be burning less calories because you're not going to be moving nearly as much.
I'm almost certain the reason your weight has stayed stagnant doesn't have much to do with you being sick, though. There are too many other factors.ahhh... moderation you've gotten the best of me.

And to answer your question, yes, your metabolic rate increases slightly when sick, however for a common cold it is not very much. As mentioned above you are likely to be using less energy due to not moving as much.

I'm not an expert but when I had the flu in early april..put me out of commission for about a week...I had extremely high fever and muscle fatigue like I had been lifting brickloads of weights for the first couple of days. Def. a lot of sweat. Of course I could barely eat and my diet consisted majority of crackers,sprite and Tylenol. I ended up going from ~194 to about 188 in a week. I thought that it was due to a fluid drop in my body but after 1-2 weeks and to this day I am still at 188.

Firstly,when you are sick you don't eat appropriate diet that makes you weak and guides it to utilize the stored fat that makes you loose weight.
Secondly,when you are sick there's most probably an infection, to tackle it body make use of the available resources hence increase heat and BMR that also decreases the weight

You burn more calories when you are active. Physically active. Not mentally active, under physiological stress of being sick.
When one is sick, they general will want the comfort of a bed and will not be active enough to get very hungry. Hence, one will eat less when sick. On account of this, a week expires and wouldn't you know you've lost some weight and 'you credit this loss to your illness'.
This, now, is not because your metabolism was raised. Your metabolism has lowered. YOU WERE IN A PARASYMPATHETIC RESPONSE STATE. YOU WERE IN A PARASYMPATHETIC RESPONSE STATE. YOU WERE IN A PARASYMPATHETIC RESPONSE STATE.
Your body's biological clocks were all sloooowed down. Your metabolism was slowed down. You just didn't bring in enough food and you flushed out much water to eliminate debris because, if you were good, you were drinking plenty of water. So, you gave yourself a diuretic effect by pumping yourself full of fluids which, naturally, got depleted.

Want to burn more calories? Get a decent size burn. Seriously, badly burnt patients will burn 10k+ calories per day without moving around at all while the body tries to use a ton of calories and protein to regrow the burnt tissue.6'3"
