Calories and weight loss Anonymous
Hey /fit/, I've been trying to eat right and exercise more for the last year and so far the results have been pretty much good. But there's something I've never quite understood.

How do calories effect weight and weight lost? In particular the calories in food (like listed on the nutrition facts) compared to the calories burnt in exercise?

The average diet is supposed to be 2,000 calories a day with exercise, right? But when I exercise on a calorie counting treadmill, it seems that power walking a mile on it only burns at most 200 or so calories? Can someone explain this to someone who was asleep in health class?

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.

BF% or Body Fat Percentage is another more accurate tool for calculating the calories by


For a better explaination

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.
