So scientifically, when does the fat come off?
Replies

It occurs right after morning stinky and tinkle0

when you put nothing down your gullet.0

Not a science nerd - just trying a purely speculative common sense analysis - you eat at a calorie deficit so that you are taking in less "food fuel" than your body is burning - during the day when your are eating regularly you are burning your food fuel - but at night you take in none - so for some period of time in your last hours of sleep and the time before breakfast you have burned off all of yesterday food fuel and your body has to convert body mass to fuel you through your deficit until you begin taking in calories at breakfast
So, I'd say you are probably burning off mass for an hour or two before breakfast.
(But I could be totally wrong)
was looking for the joke in there. Couldn't find it. Did i miss something or did you answer this question seriously?
You are one of the few my friend. And i agree. That is most likely how it's done. Once you've blown past the calories you've eaten that day and started burning more than that, you are burning off the excess stored fat immediately. All the little fluctuations and weird numbers on the scale are just water retention0 -
I do alternate day fasting. I never lose weight after a fast day, it's always 2 days later after a normal eating day.
I've also recently incorporated 16:8 where you fast for 16 hours, I go for a max of 20 hours. As everything I've read says optimal fat burning time is between 14-16 hours after your last meal, (no food/calories for 16hrs) And lo and behold my weight loss has sped up without reducing my calories!0 -
your body is constantly storing and burning fat, 'fat loss' occurs when net oxidation is greater than storage, and generally happens within a few hours, so yes you would have essentially already lost fat that same day0

National Geographic asked the hypothetical, "What would happen if all the people disappeared off the face of the earth?". An immediate effect would be a drop in temperature world-wide. Each of us gives off about as much heat as a sixty-watt light bulb (poor light bulb; it is quickly disappearing).
It gave me a new image of us as human beings. We're little sixty watt heat furnaces walking around, burning off the energy we consume. All the time.

The end products of fat metabolization are water and carbon dioxide. When you lose the water and C02, you've lost the fat weight.
Yep.

I once learned on these here fora that you pee it out and it looks like chicken fat floating in the toilet.0

Your body is actually processing fat (and other stuff) all the time. When the rate at which it is using fat exceeds the rate at which it is storing fat, you lose weight. When you have a calorie deficit, the body lacks the materials it needs to store fat, so it doesn't store as much, even though you continue to use fat at an even higher rate because you don't have as much food in your stomach to get energy from.0

This is a thread I *gotta* see...0 -
I can't say I've ever studied my pee that closely lol0

"Fat is stored inside the fat cell in the form of triaglycerol. The fat is not burned right there in the fat cell, it must be liberated from the fat cell through somewhat complex hormonal/enzymatic pathways. When stimulated to do so, the fat cell simply releases its contents (triaglycerol) into the bloodstream as free fatty acids (FFA's), and they are transported through the blood to the tissues where the energy is needed."

I believe that thread was referring to ketone bodies. Ketones are made when your body uses fat for energy. I've had a ketone level of "4" (my Dr. says that is the highest that the blood test she sent me for measures), but I've never seen oil floating on my pee. I can, however, smell the acetone when I am in ketosis. My urine tends to be darker at that time, even though I drink a lot of water (ketosis makes me thirsty). The body is not good at putting excess ketones back into fat, once they are made, so they get excreted in the urine. Some people also have "fruity" breath from the acetone. So, some fat ends up being peed out, and some you breathe out.
You burn fat when you run out of glucose. So, if I eat a 300 calorie breakfast, then burn 350 calories in a jog, the 50 extra calories came from fat. I would then continue to burn fat until I ate again, at which point I would switch back to using glucose until all the meal has been digested and used up. In a calorie deficit, you probably start each day without a lot of glucose left to burn. On the other hand, when you convert the food you digest to glucose, anything that isn't used right away, or stored in your muscles, is put into fat cells by insulin. So, throughout the day, and night, you are switching from burning to making fat, and back again.0 -

Your question made me curious. I learned something I didn't know before, so thanks:
"Exercise and diet can help you lose weight by creating a calorie deficit. Your body will begin to break down stored fat through a series of complicated metabolic pathways. The byproducts of fat metabolism are expelled through your lungs, sweat and urine, while the energy liberated from fat is used to maintain your body's biological function."
http://www.livestrong.com/article/325306-how-does-fat-leave-your-body-when-you-lose-weight/
So, I guess the answer to your question is that the fat comes out when your body runs out of nutrients from your food, and has to tap into the fat reserves. The free fatty acids are liberated from your fat cells, and used for energy. The byproducts are released through your sweat, urine, and breath.

exactly.
you burn fat all the time. when you're sleeping, your body is using fat as fuel. as long as you don't overeat your calories (and thereby storing fat), you're burning fat.
if you exercise, there will be an increase in fat burning when you begin the exercise, and for some time afterward before your body goes back to "normal".0 -

No, there was nothing that sophisticated involved in that thread.0 -

That's interesting, because I almost always lose scale weight after a fast day.
Do you mean a true fast, as in nothing but water, or a low calorie day called a "fast day" in IF circles?0 -
