My fitness pal question

Hello all,

I'm a 5'10" 240 lb man with a moderately active lifestyle (work in the trades). Im trying to cut down to around 180 lbs and I am not great at dieting so Ive been using myfitnesspal. They recommended 2700 calories a day which seems high to me but at the same time I'm incredibly hungry around 2400 and 180g of protein. Any advice on how I can sustain a defect would be much appreciated.
