How many calories you need to burn in a day depends on how many you eat.

If you're cutting down your caloric intake, you will need to burn fewer calories in exercise.

Your calorie deficit needs to be 500 cals a day to lose a pound a week.

Find how many calories you NEED to live (your BMR): http://www.bmi-calculator.net/bmr-calcul… MULTIPLY this by your normal activity amount (your job, etc., not your exercise): http://www.bmi-calculator.net/bmr-calcul…

That will tell you how many calories you need to maintain your current weight.

Your calorie deficit is the combination of diet (how many fewer calories you eat than your daily needs) and your exercise amount.

Example: I have a BMR of about 1680. I'm sedentary, so I multiply that by 1.2 and get 2016. To lose one pound a week, I need to eat 500 fewer calories a day (1516 calories), exercise and burn 500 calories a day while eating my 2016 calories, or a combination of reducing calories and burning through exercise.

Hope this isn't too technical! If it is, you can go to sparkpeople.com and sign up - if you put in your information and weight loss goals, it'll calculate your daily caloric needs.

To lose weight (I assume you mean fat?) on your arms, you have to lose it from all over, which means burning fat through diet and exercise. You can do all the weight exercises in the world - it'll build your muscle, but it won't get rid of the fat that's over that muscle.

Your body does need SOME fat coming in through your diet, so don't cut out fats altogether. Some good lowfat foods are fruits and veggies (although some, like avocado, do contain fat, but it's "good" fat), skim milk, egg whites...
