Count calories and exercise. You will lose weight if your calorie intake is less than your calorie expenditure.\n\nThe easiest way to limit your calories is to watch the fats & sweets. Fat has 9 calories per gram. Protein & carbs are 4 calories per gram. BUT it does all come down to using more calories than you take in.

Look online for a metabolism calculator to give a rough idea of how many calories you're burning on an average basis (it's based on your activity level during the day-- whether you sit at a desk all day or work construction). Based on the numbers you plug in (combined with current height and weight information), you'll get an estimate of the total number of calories need to maintain your current weight. \n\nThen, you just take in more calories than that. \n\nI would suggest that you try to take in calories from good sources, rather than pigging out on Devil Dogs or Twinkies. Presumably, you want the weight to be packed on in the form of muscle, so you need to give your body the right kinds of raw materials to do the job. Use good sources of protein.

I am not a doctor but in general the equation is very simple: Calories Consumed - Calories Used = Weight Loss (or gain).\n\nWithout a plan to change their diet, most people regain the weight.\n\n\nMike Honeycutt

A calorie is a unit of energy, it's a way to measure it.  Food is converted to energy when it is digested.  Then stored as fat if you dont use it. Whichever has more calories marshmellow or walnut, is the one with more energy

A calorie is the quantity of thermal energy required to raise one gram of water 1°C at 15°C.\n\nCarbohydrates have 4 calories per gram. Proteins have 4 calories per gram. Alcohol has 7 calories per gram. Fat has 9 calories per gram. Knowing this, you just add up the calories to get the total amount in an item of food/drink.

For one, you body uses the energy to burn fat and calories on its own, also your body uses the energy to give <i>you</i> personally, energy to be able to take on the day. Think of it this way: Go a few hours or so without food (like.. skip a meal or something). Take a note on how not eating for so long makes you feel. Then eat something, and make a note on how that makes you feel. That way you have not only the right idea, but also a first-hand experience of what you are trying to find out. (Plus it's a good science project ;-P)

It depends on your height, weight, age, and sex.  There are several online calculators that ascertain your particular basal metabolic rate, or how many calories YOU burn in a day.  Once you find that out, you can use that number to lose weight by creating a calorie deficit by eating x number less than your bmr and/or burning them off through exercise.\nHere is a link to a metabolic calculator-\nhttp://www.internetfitness.com/calculators/bmr.htm\n3500 calories equals a pound.  Consume 3500 more than you need/burn, you will gain one pound.  Consume/Burn 3500 less than you need, you will lose one pound.  Aim for 500 to 1000 calories less than your bmr to lose 1-2 pounds per week.  Any added exercise can only increase the results, so exercise away.

It depends "how" you are burning these calories. Every person has a BMR (basal metabolic rate) which indicates how many calories your body will burn daily. This is also usually the daily recommended calorie intake for the individual. For example, my BMR is 1418 calories, and I burn 425 calories from digestion and processing food. Thus, I am to eat 1418 calories a day to MAINTAIN my weight, my body will not "hold on" to these calories. To lose weight, you must burn more than you consume.\n\nIf you are working out and burning 1000 calories, this is a bit on the high side. It also depends on the intensity of the activity, your average heart rate, your diet, and your weight and fitness level! And be careful, what the machines at the gym tell you is usually not accurate (if this is where you are getting the information from) and you should take the calorie values as an estimate. You will usually burn 10-20% less than what the machine displays. Sad, I know :(

Don't eat more calories a day than your body can burn off. Say for example, your body burns about 1200 a day, eat no more than 1200 calories a day. But it depends on your level of activity on a daily basis. Mine is 2000. I work at a computer and have minimal activity, so its pretty low. So find out what yours is and dont go over.

The calorie we see on food is really the kilocalorie.\n\nA kilocalorie is the amount of energy needed to increase the temperature of 1 kilogram of water by 1 degree Celsius under Standard Temperature and Pressure.

First you need to find out your body fat %, then from that you can find you resting metabolic rate (RMR)\nthe formula is: RMR=lean body mass(pounds)/2.205*30.4 this how many calories that your body burn at rest in one day with no activity. then after that go to http://www.healthdiscovery.net/links/die... and calculate you exercise and add everything together. and that should tell you how many calories you need to eat for you Diet depending of your fitness goals. Every 3500 calories is 1lbs

3500 calories equals one pound so just up your calories depending on how much you want to gain.

okay.. just to let u in on some info... (dont listen to the people above.. they have no clue) ... anyways... everything you do in a day burns calories... watching tv, eating, sleeping, even reading a book burns calories. ur body will burn them all day long.. but if you also add a wieghtliftin program then it will REALLY help

Depends on your age, gender and personal and family health history.  Cut back at least 500 calories a day from what you are eating now and add some exercise.  One pound of fat is equal to 3500 calories, so in 7 days, you'll lose 1 lb, just by eating less.  If you add exercise on top of that, you should be able to lose up to 3 lbs or so a week.

If you don't want to lose weight but are exercising, then you must take in more calories.  Eat appropriately.  Consult a physical trainer or your doctor to help you determine how many calories you should be taking in.
