Conventional wisdom has it that one need to burn 3,500 calories to burn one pound of body fat.
It is a lot trickier to determine, though, how many calories people ACTUALLY burn when they engage in physical activities. Most pieces of cardiovascular equipment will give a readout of caloric expenditure after the body weight has been entered but this is at best an approximation.

Answer is C but do not really suggest tracking (unless prepping for a comp) due the psychological disadvantage. Counting calories burned or intake is just not healthy to do in my opinion. It is not realistic and not necessary to lose weight. Imposing a commitment of counting will likely set you up for success because it is very difficult to maintain that. Also, losing one pound of fat a week is nice but not realistic for most. I would say half a pound is generally more realistic for most populations. Setting goals that are more attainable will likely result in more success.

3,500 calories burnt is one pound lost. Karin brought up a great point when she said that exercise equipment offers an approximation at best as far as accurate caloric expenditure goes. To figure out exactly what your metabolic rate is at any given time, you have to look at METs. As a measure of oxygen uptake in ml/kg/min... 1 MET is about 3.5 ml/kg/min... What's cool about METs is that some pieces of equipment that measure METs (by estimate) can help trainers to figure out what the intensity of the exercise is for the client. Really heavy intensity exercise like jumping rope is about 10 METs. This translates into a kind of RPE chart without the chart, roughly.
Of course, Resting Metabolic Rate is dependent upon so many different extraneous environmental and physical factors, that even MET measurements are, unfortunately, a best educated guess unless in a medical setting with proper equipment to measure everything and control for other stuff.

I am with Karin on this one. I have read that some cardiovascular equipment will give a read that that is up to 20% off what a person is ACTUALLY burning.

A great way to determine how many calories you burn in a day would be to use your own heart rate monitor or a body bugg. Once you know your calories burned for that day, then you will be able to figure out how much you should eat in a day to lose that one pound of fat. If you work hard at it, you should lose one pound of fat per week.

C) 3500 but an intense 1000cal workout will shed a pound as well due to metabolic demands.

to lose 1 pound you need to burn 3500 calories. But the calories you burn during any particular exercise session are only part of the equation. the intensity of your exercise sessions can keep you burning extra calories long after you have finished the workout. This afterburn can be the key to efficient weight loss.

The answer in a test tube is 3500. The confusion in reality is that we don't know how each individual reacts to exercise after eating and during different activities, so it is impossible to calculate without measuring expired gasses during daily activities and exercise (too complicated, too many variables). Heart rate does not tell you what type of calories you are burning, but that doesn't mean you cant use a monitor to your advantage. Most importantly, you should be thinking about the exact effects that each bout of exercise has on your hormone system and metabolism over the remainder of the day, not just calories per bout of exercise. Find the book Modern Nutrition in Health and Disease by Goodhart and Shils. See page 29! This is where it gets interesting- If I take a diuretic and lose a lb of weight, did I burn a lb of fat? If a women is on Prednisone or hormone Replacement Therapy (yes this is common) and you put them on a calorie restriction diet will they lose a lb of fat? Ever? Great question for debate and who cares what cardio machines say? Do people still use those things...

Yep, the text book answer is (c) 3500 calories. As stated before, counting calories is an "approximation" at best. One reason that I focus on body fat reduction and how clothes are fitting is to try to take some of the guess work, and required hyper-vigilance of counting calories out of the whole equation. I want my clients to focus on the end results, the forest if you will, instead of the day-to-day, and very tedious job of calorie counting.

Perhaps a more effective way to adress your question is to recognize that losing weight is based on energy balance, calories in versus calories out. The evidence suggests that a negative energy balance of approximately 3,500 kilocalories will lead to a weight loss of a pound. This simply means that we need to expend 3,500 more kilocalories than we consume in order to lose a pound.
That's why I encourage clients to keep a detailed 3-day dietary record to determine if there may be ways to eliminate unnecessary caloric intake. But keep in mind that adequate intake is essential in order to give the body adequate energy reserves to support the vigorous exercise that is the key to effective weight loss and long-term weight management.
Take care.

Science indicates that a pound of fat is equal to 3500 calories. Unfortunately it is not that simple in terms of counting calories in vs. calories out! A heart rate monitor and a metabolic test like we recommend at Life Time Fitness can give you an edge in burning more fat calories at each workout by knowing what fuel source (carbs/fat) you are using at each specific heart rate zone and designing a progressive cardiovascular program based on those heart rate zones. There is also the concept of improving your Metabolic Efficiency through proper nutrition...what and when you eat specific foods/fuel to increase your body's fat utilization throughout the entire day. Another place to look for those that are stuck with weight loss is that your cortisol levels (stress hormone) may be off throughout the day. This can be caused from various factors including work, lack of sleep, overtraining and environmental. If your optimal cortisol level are off throughout the day it will make it very difficult for you to lose fat and your risk of having other serious complications down the road increases dramatically. At Life Time Fitness we offer a test that will measure your cortisol levels 4x throughout the day to determine what is going on INSIDE your body. After your results are analyzed by a Registered Dietician on staff your Personal Trainer will adjust your workout program and suggest specific supplementation to help get your cortisol levels throughout the day to optimal levels...thereby improving your body's ability to use fat as a fuel source.
I could go on and on forever about this...the best recommendation I can give you is meet with a Fitness Professional and find out where the best place is to start for you as an individual.
