I know only enough physics to be dangerous. In fact, today I was wondering if walking one mile up a hill and then a mile down would be the same as walking for two miles on flat ground. It would seem the same energy would be used and so the same number of calories burned in either situation. This probably wouldn't hold for driving as there are inherent losses due to friction and the percentage of burnt gas that actually went into forward propulsion. When walking though? Help me, if you are smart to know about such things.
I'm trying to include walking as exercise. I have estimated that walking uptown and back can burn about 300 calories. I need to run a deficit of 500 to 600 per day in order to continue losing around 5 lbs a month.
I did hit a minor milestone today as it was the first time I saw 177 pounds on my bathroom scales. That's the equivalent of 80 kilograms which was once an end goal. My current driver's license says I'm 90 kg (200 lbs) and the one prior, used to read 106 kg (235 lbs).
I've moved the goal posts however. I'm on my way to 75 kg (165 lbs) now, even though that might not happen until October!
