I pretty much understand the whole weight loss thing. My question is about calories.
Now everyone (including myself) always says that you need to burn more calories than you consume to lose weight. This seems pretty straight forward, but does that actually mean:
You eat 2500 calories a day
You need to burn AT LEAST 2501 calories to start to lose anything?
Because one day, I walked constantly for 7 hours. It wasn't planned: me and a friend walked to the city, browsed shops, then just took a long walk as the sun set, and then walked home. I used to have an app on my iPod Touch. You put in how much exercise you've done, and what you've eaten. I put "brisk walking, 7 hours" in, and it only said I burned 1600 calories?! So I would have had to burn 900 more calories (assuming I consume 2500 calories a day) ? Because that seems crazy. My body felt like jelly after all that walking, and I still needed to do MORE just to lose weight?

Now, keep in mind, that for most people the average basal metabolic rate is around 1800 calories. This is throughout a day, doing sedentary things such as sleeping, showering, food prep, cleaning around the house, you know typical things that wouldn't be considered "physical activity". Now if you walk for 7 hours, you are going to burn at LEAST ~1000 calories (walking is about 200 cals/hour).... That being said you are either on your way to losing weight or you need to eat some more if you are trying to maintain weight.
So, on this day, you probably burned at least 2700 calories, because you are always burning calories, even while you sleep. What I am trying to say is that your body wasn't only burning calories when you walked through the city, it was doing it before and after as well. You would've burned those "other 900 calories" you mentioned at some other point of the day, for sure.
