I am a 224lbs, 5'57 23 y/o male, placing me at a BMR right below 2800. If I multiply that by 1.2 (sedentary) I get 3360, which is roughly FIVE TIMES what I've eaten today. I do still have one more meal to go, but given my numbers I should already be dropping pounds like there was no tomorrow. If I really want to feel full today, I could go to the store and buy a 400g pizza, which on the label tells me that it has 222 calories per 100 grams, giving the whole pizza a calorie amount of 888 (let's say 900 for measure). Now, according to this I could potentially eat two of those pizzas and still lose weight, punching in at 1800 calories + 700 from earlier. That would put me at 2500 calories (yay, I can eat two pizzas and lose weight!) How can I make sense of this? Have I terribly butchered my math, or my metabolism?
