If I eat 1500 calories a day and burn 500 from 45 minutes of exercise on the exercise bicycle, will I lose 1000 calories a day?
If your numbers are accurate, yes, sort of.First off, you don’t lose calories, you simply have a shortfall in providing the typical daily energy needed to maintain your current body mass. What you lose is mass. microscopically.What you are describing is a starvation diet. While you may lose weight doing this at the start (assuming you can go 1000 calories short every day and otherwise meet your requirement for micronutrients, especially those required to make the enzymes that burn fat), if you stop this diet you may find that you have also set your basal metabolic rate to a lower default, one from which it will no longer budge.Weight loss should be achieved slowly by maintaining a sleight calorie deficit, one that does not undermine your nutritional needs, which become more refined and less tolerant to crappy foods as you get fitter!Shortcuts (except literal physical shortcuts), while enticing to the impatient, are most often wolves in sheep’s clothing.
How much weight will I lose if I take 500 to 600 calories per day with workouts?
Assuming you are -500 to -600 calories a day and not eating more than you are burning, you'll lose about a pound a week. 1 gram of fat has about 9 calories. 1 pound of fat is about 450grams.(450X9=4050calories).Let's say you average 550 calories per workout…4050/550=just over 7days.The Mayo clinic has slightly different numbers but the general outcome is the same, they say “Because 3,500 calories equals about 1 pound (0.45 kilogram) of fat, you need to burn 3,500 calories more than you take in to lose 1 pound. So, in general, if you cut 500 calories from your typical diet each day, you'd lose about 1 pound a week (500 calories x 7 days = 3,500 calories).”If you are aiming to lose weight to change your size, be mindful that if you gain muscle while losing fat you may be getting smaller but still weigh the same as muscle is more dense. Having said this, I suggest measuring the size of different areas of your body to gage progress - or pay attention to how your clothing fits, not just the numbers on a scale.
How many calories per day do I need to burn to lose weight?
A human body consists of fats (in the form of adipose tissue), carbohydrates (in the form of glucose and glycogen) and proteins (in the form of muscle). If I have to lose weight, I ll talk in terms of losing either fat, carbs or proteins. Below is a table lifted off Wikipedia for ready reference.As can be gathered from the table, a gram of 'fat' can release up to 9 kcal of energy, more than double the figure for proteins and carbohydrates. Therefore if you want to lose a pound of fat you will have to burn 0.453*9 kcals ~ 4082 cal. Similarly to lose a pound of carbohydrates you will have to burn 2041 cal. Therefore if you burn lets say a 100 cal, you will be burning a lot less fat (in terms of mass) compared to carbohydrates.Let me elaborate with the help of a story at the end of which you will understand the concept of losing weight.Ram is an athlete and runs regularly. Today he ran 5 km in 25 minutes. Running is the act of contracting a whole range of muscles and releasing them in a synchronous manner. While we may think that running involves only leg muscles, it is a combination of movement of many more areas of the body (arms, shoulders etc.). This requires energy to do so. Energy can be obtained readily from breaking down Adenosine triphosphate. All the substrates (fat, carbs, protein) that we mentioned earlier create energy packed ATP when required. But this conversion of substrates to ATP requires Oxygen (aerobic respiration). No wonder Ram breathes faster while running. But how can Ram ensure that he burns fat only and not the carbohydrates and protein. Ram can't. His brain decides what to burn and in what proportion. There is a way however by which Ram can measure what he is burning. The composition of CO2 while exhaling can tell us how much oxygen was used in burning fat, carbohydrates and protein (a little knowledge in chemical reactions and math will help). Therefore with careful observation, Ram can figure out how much oxygen he has consumed while running and in what ratio has it been used to burn the substrates. Once he has that he will know exactly how much fat and carbs he has utilized.Now the part which is missed by a lot. Ram is also hungry at the end of the run. He eats a peanut butter sandwich which is filled with carbohydrates and fat thereby restoring whatever he had lost as part of the workout. And so he neither loses nor gains any weight. The trick is to outgo more than you inlet energy substrates.Happy Workout
How much weight will I lose eating 500 calories a day for 5 days?
If you have an average Basal metabolic rate in the 1500-1800 calories range, you eat 500 calories per day, and you are minimally active, your daily deficit will be 1300 to 1600 range. Over five days, you can expect to lose somewhere between 1.5 and 2.5 pounds.What you see on the scale will look higher though, because you'll have probably lost some fluid and you will have emptied your digestive tract. That could make it seem like you’ve lost somewhere between 5 and 10 pounds, bit ot will not be real weight loss. You'll gain that back within a day or two of going back to normal eating again. You can lose a bit more than that 1.5 - 2.5 pounds, and maybe bring it up to as much as 3 pounds if you exercise on each of those three days, or 3.5 pounds if you exercise strenuously enough to burn an extra 1200 calories per day - but by the end of the second or third day you'll likely not have a whole lot of energy for that.And let me be clear: While a five day near-fast of 500 calories/day is unlikely to do any permanent damage, this is not a healthy way to lose weight, and you should not even attempt it without discussing your intentions with a physician who is familiar with your medical condition, lab results, and history.

If I eat 1250 calories a day and burn 700 of them in gym how much weight can I lose?
Well, if your goal is to get healthy, this isn't the way to do it. One of two things will happen: 1) Your body will enter into "famine mode." This is when you are eating too little to sustain your body's activities. Your body will believe that there must be a famine in the land, and as a survival mechanism, it will start to store more fat on your body. 2) Your body will be so deprived of proper nutrition that it will start to consume muscle mass to burn for energy. Severe caloric restriction is also known as anorexia and can lead to lifelong problems with food as well as heart arrhythmia. Naturally, you'll also feel weaker and weaker, not stronger, as you exercise more and more. WHY? Most people require at LEAST 1200 calories a day just to beat their hearts, work their lungs, blink their eyelids, run their digestion, and other "tiny" things like that. If you're also planning on doing 700 calories of extra work at the gym, your body will only be left with 500 calories to run your heart, lungs, and basically your whole body. Surely you can see how this will cause some problems, running a 1200-calorie body on only 500 leftover calories. What do you think your body will cut back on to help you run on so little? Heart function? Lung function? When you exercise, you need to eat MORE calories that day to fuel the workout without interfering with your normal bodily functions. Go to http://www.dailyplate.com . Enter in all your information and tell it that you want to lose 2 lbs a week (a safe rate). It will tell you how many calories you need to eat every day as a baseline. Then, you need extra calories on days when you work out. EDIT: You have added a lot of rants to your question, but you still don't have a clue how metabolism actually functions. You still don't get it. Please see your doctor before beginning a weight loss regimen. You are too young and unguided and uneducated to construct a healthy plan on your own. You can do as much exercise as you want and eat as much as you want, just make sure that when you take total calories minus exercise, that the number is still above 1200, k? 1500 calories - 500 exercise = 1000. Too low. 1700 calories - 350 calories = 1350. That's fine, healthy, and will cause healthy weight loss.
