Ok, so can someone explain something to me?? When they say "burn 500 more calories a day than you eat and youll lose 1 lb a week does that include your BMR? (I hope this question makes sense)
Scenario:
For example... A 5'6" 180lb, 26 year old females BMR (the amount of calories your body burns at rest) is 1626.
If you eat 1200 calories a day your caloric defecit is 426. (You should lose 0.852 pounds per week)
If you exercise and burn 300 calories everyday then the defecit will be a total of 726 calories. (You should lose 1.452 pounds per week)
Or... are we supposed to eat, for example, 1200 calories a day AND burn 1700 calories a day? That seems almost impossible to me, not that its impossible to burn that many calories a day but it seems like theres not enough hours in the day to accomplish that.
*The numbers I chose are just random, but my calculations should be correct, but if Im wrong please tell me!

MFP also adds an activity factor since we aren't typically at rest all day. For a sedentary person, it is 20% over your BMR. This would account for normal daily activities like dishes, laundry, showering and going to work or school. I'm assuming the 300 calories of exercise is above your normal activity level. If so, your calorie deficit would be 325 calories higher than stated in your post (1626 x 20%).
BMR 1,626 x activity factor of 1.2 = 1,926 + 300 calories extra exercise = 2,226 total calories burned. If you consume 1,200 calories then your calorie deficit is 1,026 per day which should equate to 2.05 pounds per week.0 -
Ok, that helps a little. How do you MFP adds "activity factor"? I would like to read more about it. But can you anser my other question also?? Im assuming the answer is yes but when they say burn 500 calories more than you eat everyday, is that including your BMR?MFP also adds an activity factor since we aren't typically at rest all day.

Search Harris Benedict formula for activity factors. You were asked yours when you set up MFP profile and yes that would include your BMR.
Feel free to message or friend me. Like you, I like to understand how it all works.0
