It takes 3,500 calories burned (more than consumed) to lose one solid pound of weight.
One pound = 3500 calories. Decreasing calories by 500 per day for a week = 3500 calories lost or 1 pound.
You can burn 150 to 250 calories for 15 minutes. Calories burned also depends on how much you sweat and how overweight you are.
There is absolutely no way to measure that because they are not at all related. You can sweat by sitting in a hot room and not moving (hardly any calories burned), and you can burn tons of calories by shivering or swimming in a cold lake (hardly any sweat).
There are no calories in water

If you eat 100 calories and burn 200 calories, you create a calorie deficit of 100. It takes about 3600 calories lost to lose one pound. So in this case you'd have lost 1/36 of a pound.

So you burned 300 calories on the elliptical this morning? Great! But if you are adding up your calories to lose weight you need to know your Net calories burned, not your Gross calories. I won't get too into the technical/mathematical side of things, but here we go... Did you know that 3,500 calories equals one pound of fat? Well, if you are using exercise to burn those 3,500 calories you need to factor OUT what you would have burned if you did no activity during that time you exercised. Let's say, for example, your resting metabolic rate has you burning 80 calories per hour doing absolutely nothing. Yep, even while you are sleeping you are burning those calories. Now maybe instead of taking a nap for 1 hour you decide to go to the gym to workout. So you hop on the elliptical for an hour and burn 500 calories. You do this every day of the week and on the 7th day you weigh yourself expecting to have lost 1 pound since you burned 500 calories each day on the elliptical. Well, if you didn't notice any weight loss it might be because you didn't actually burn 3,500 calories more than you normally do. Multiply the 80 calories you would have burned sleeping during that hour each day by those 7 days (80 x 7), subtract it from 3,500 calories and you actually only burned 2,940 (NET) calories (560 calories short of burning enough to lose one pound). It may not seem like 80 calories not considered each day makes a big difference but over 365 days that is 29,200 calories - which equates to an additional 8 pounds that won't be lost each year if you forget to factor OUT the resting calories you would burn anyway. So do one to two more days of the elliptical, or whatever way you prefer to exercise, before weighing in after that first "week" and you should be close to losing that pound. Or burn 600 GROSS calories each hour/day doing exercise and you will be right around 3,500 additional calories burned per week. But hey, our bodies aren't perfect - they don't always follow the mathematical rules to weight loss- just be patient and give it time.
Calories are not lost during chronic diarrhea. Critical nutrients and water are lost during chronic diarrhea which can lead to dehydration.
An average person, at rest, will need about 60 calories per hour to stay alive (about 1,500 calories per day). A moderately active person will burn another 500 calories a day in his activities of daily living. So, on average, a person needs 2,000 calories a day. Now, there is about 4,000 calories (1 gram of fat =9 calories, times 454 grams in a pound) to a pound of fat. For every 10 grams of fat lost, there is about a gram of water that it is lost with it. Thus, you really need to burn about 3,600 calories to lose one pound. If you are eating only 100 calories a day, you would be losing 1,900 calories in a day, or 13,300 calories in a week, which is about 3 and 1/2 pounds of weight loss. There is one more wrinkle to this, though. When you initially begin to lose weight, the body will first lose the stores of glycogen in the liver. The body stores about 2 pounds of glycogen. Glycogen loves water, and for every pound of glycogen, there is between 1-2 pounds (really 1/2 liter) of water with the glycogen. So, for every gram of glycogen lost, there is about 1 centiliter of water lost. Unlike fat, glycogen produces only 4 calories per gram. So, 2 pounds of glycogen produce only 3,600 calories (454 grams in 1 lb X 2 lb X 4 calories per gram). So, within 2 days, an ordinary person, having lost 3,600 calories, will lose 2 lb of glycogen, and 2 lb of water! Therefore, within the first 2 days, the person will have lost 4 lb of weight! When you consider the above, then, on a 100 calorie a day diet, an ordinary person will lose about 6.5 lb of weight in the first week. Thereafter, he will lose about 3.5 lb per week. Note that I have ignored other mechanisms such as the body converting metabolic systems into a starvation mode. Thus, for example, basal metabolic rate(BMR) decreases as the body enters a starvation mode, so that fewer calories are burned at rest when someone starves himself. As well, on 100 calories a day, a person will not get enough protein, forcing the body to break down muscle in order to sustain itself. Less muscle means lower BMR which again diminishes the calories lost. Hope that helps.
The amount of fat lost when one burns calories is hard to determine but one is assured of losing weight when he or she loses calories.
