When you lose wieght,Can you feel it?

Okay,so when u lose wieght and ur on the bigger side can u feel it Or do you see it first? I've always heard u feel it before u actually see it. Is this true? I've weighted myself n it says I've lost 15 pounds in the last 4 weeks. Based on technicality it adds up.(Calculating how many calories I need to maintain my current weight witch is 2899 and subtracting it by 2000 (cuz 4x500=2000) 500 is what u need to lose wieght .they say by taking 500 calories away from daily normal calorie in take will equal 3500 over a week. (3500=1 pound) so cuz I eat 900 -1000 calories a day I will lose 4 pounds a week- 4x4 =16)But I don't feel like I've lost wieght. P.s I'm 250 n now 235 please help!!!
