I was looking over at nutritiondata.com at their BMI & Calories Burned Calculator. Currently I am 22, I am 5'9, and weigh 187. I listed myself as active. I go to the gym usually around 5 days a week. Under excercise options I listed weighlifting moderately for 30 minutes each time, and I put the treadmill for 30 (I do the eliptical and it wasn't listed). It said my BMI is 28.1 which is a little high, but it says it estimates I burn 3850 calories a day. Doesn't that seem a little high? I tracked my calorie in-take today, and I have had 1915 calories and I am pretty much done eating for the day. So if this is relatively correct, I roughly burned 1800 calories of fat today. I am sure my average nutrition ranges higher, but if this were correct I burned almost half a pound today? Are there more accurate calculators?
