Eat what you burn

Hello - Not sure if this of interest to anyone but I've lost about 60 lbs (20%+) of body weight in 6 months. It was pretty simple (not easy). I use Myfitnesspal to track calories I intake and exercise calories I burn and used their RMR calculator for my sex, weight and height and calculated my resting metabolic rate in calories. I created a spreadsheet that keeps track of the simple math, Calories consumed - Calories burned - RMR = net calories . Divide that by 3500 and you get how many pounds you lost that day. Doesn't matter what kind of food I eat the formula can predict my actual weight with a tolerance of 1-2%. If I haven't lost any weight on the scale I look at the sheet and it is dead on accurate (I ate too much or burned too little). I adjust the RMR down as I lose weight. I view losing weight as pain management. Which pain can I tolerate more? Not eating as many calories or burning more calories. I've always sided with burning more as it is less painful for me so I do twice a days in the gym for 45 minutes each session. This has the added value of bumping my metabolism twice a day instead of once. Not sure if it really helps but it has some intuitive logic to it. Not everyone can go to the gym everyday let alone twice a day, but at least this approach gives you an understanding why you shouldn't get discouraged its just the math.
