Ht. 5'3", Wt. 150 - hey guys, i havent posted in a while so i thought i should. In my health class i learned that 3500 calories = 1 pound, so 3500 calories extra over a period of time causes 1 pound gain, but it works the other way also, so like eat 500 less calories a day and in 7 days you have not eaten 3500 calories. Causing a 1 pound weight lose.
