 UNIDENT Posts: 33,498 9/3/12 2:33 A A word on net calories. Subtracting today's exercise burn from today's food intake tells you nothing useful whatsoever. Let's take a look at three people with identical "net calories"... Suzy takes in 2,000 calories a day and does 500 calories a day of exercise. That's a net calories of 1500. Suzy is a muscular physique, and takes 1800 calories per day to sustain herself before exercise. So with 500 calories burned, she's burning 2300 calories daily. The difference between that and her eating (2000) is 300 calories deficit. Suzy is going to lose about a pound every 2 weeks or so at a net calories of 1500. Lily takes in 1500 calories. She doesn't like exercise, so she doesn't do any. So that's a 1500 "net calories" daily. Lily is a fairly slightish person and takes about 1500 calories daily to sustain herself before exercise. Lilly is going to maintain her weight at a net calories of 1500. Jae takes in 1700 calories and tries to do around 200 calories daily of exercise. Jae has a 1500 daily net calories. Being wheelchair bound and a small frame, she's a lot less mobile than a fully able bodied person and only burns around 1100 calories daily before exercise. So with 200 calories burned she's burning 1300 calories per day, but taking in 1700. Jae will gain a pound every 1.5 weeks or so at a net calories of 1500. See how it's a completely useless figure by itself? Three different people all with an identical "net calories", and one will gain, one will lose, and one will maintain. You don't learn anything by subtracting exercise from food. This figure is not a useful piece of information. You need to add exercise to BMR and daily activity burn, and then subtract food from that. At your weight, with a half to a full pound a week as a goal, you would want to see a daily result of minus 400 calories or so - the burn numbers being 400 calories in total more than you eat.

Yes, your weight shifts 1-2 pounds in a day, but that's not fat loss. That's water weight and fluid shifting. Drink 8 ounces of water, your weight goes up half a pound. Fat loss is a long-term process. You're looking for long-term downward trends. This is one reason Sparkpeople recommends one-weekly weigh ins, under the same circumstances each week. Generally speaking, first thing in the morning, on the same day each week, naked, after your morning constitutional, will give you the lowest number of the day, but your mileage may vary. It may seem weird, but it's true; 1/2-1 pound per week is far more reasonable for your current weight than 2 pounds. The closer you get, the slower it'll be. When you're within 10 pounds, you'll find it slows even more! To put it bluntly... you're not fat enough to lose 2 pounds per week consistently! That's a good problem to have.
 TIME4SUMMER Posts: 7 9/2/12 11:38 P Thanks so much for the reply. I do believe the "lose it" app takes into consideration the resting metabolic rate using the miffin equation. The calorie allowance it calculates is based on daily metabolic needs also. I can't imagine only aiming to lose 1/2-1 pound per week. My weight varies 1-2 pounds at any given time of day!
