Weight and exercise question

Hello All I am hoping someone can help me understand this losing weight thing. So I have started to count calories and do an hour of cardio and lift weights. My question is that when I do an hour on the treadmill it tells me I lose about 800 calories an hour and 400 calories when I lift weights. If I am keeping my calories to 2300 a day does this mean that I have to have 3100 calories when I do cardio and 2700 calories when I lift weights?

My 2300 calories a day is plenty and I am finding it hard to go over that. Unless I start eating a bunch of junk. Maybe I am still learning how to adjust to the diet and change. I know there are foods out there that are healthy and high in calories such as granola or nuts. Can someone help me better understand if the above is true or not. And if I don't eat what I lose in exercise how will this affect me?

That depends on whether you're trying to lose or maintain, and how fast you want to lose.  If you're trying to lose, the total you eat should be 500-1000 less than the total you burn.  If you're burning 3100 calories and eating 2300, (deficit of 800) then you should lose about 1.5 lbs a week.  (3500 calories deficit per week equals about a pound of weight loss.)  If you're trying to maintain, you need to be eating as much as you burn.

Keep in mind how much you are burning just being you.  Calorie count's burn counter calculates that automatically and adds your exercise to it.

Example: I burn 2200 calories during a typical sedentary day - no exercise, just sitting around.  If I bike to school and exercise before class, then bike home, I burn around 3000 calories a day.  My calorie eating goal is about 1900 calories a day - so on sedentary days my deficit is only 300 calories, but on high-activity days it's over 1000.  The important number isn't so much the daily deficit as the weekly deficit (you're aiming for 3500-7000 calorie deficit over a week if you're trying to lose weight).

Does that make sense?  I can't tell for sure but it sounds like you're trying to eat as much as you burn, which will NOT make you lose weight.

Perfect thanks for the reply lionpaw.
