Energy Balance = Energy Intake - Energy Expenditure
Energy intake is made up of what you eat and drink. Energy expenditure is made up of several factors including resting metabolic rate (RMR), calorie cost of activity (exercise. The balance of intake and expenditure is an important factor in weight gain or loss. If you have a positive energy balance (intake exceeds expenditure), you gain weight. A negative energy balance (intake is less than expenditure) dictates that you'll lose weight. Simple enough.
Every person has a BMI (Body Mass Index), a scale used to assess wheather person is overweight, average, underweight. It's fairly accurate in the beginning but tends to get inaccurate as body's muscle mass increases.

BMR is the amount of energy (calories) by someone during a day with almost no activity. This I think is the most important number for /fit/, from here you can accurately achieve your Weight-loss or gain goal in the coming weeks.

Just make things in prepective for weight loss /fit/, One pound of fat equals ~3,600 calories so to burn that off, reduce calorie intake and exercise. Obviously you can't cut 3500 calories from your diet or hurt yourself after hours of exercise. So best way is to aim 1-2 lbs per week, eat 20% less than your BMR x activity level. or eat about that percent more to gain if that's your goal.
