How can I get my dad to stop baking fattening desserts every other day?

his favorite recipe book is from 1963, so most of it calls for shortning, ,butter,cream cheese, everything fattening....i want to eat healthy, im over 300 pounds and my back is always hurting, my feet are killing me, and ive gained this weight since i moved back here 3 years ago. he looks like hes in his late third trimester, and he refuses REFUSES to change any of his eating habits, so fine, ok, i kept my old fridge when i moved from my old house so i buy food for myself. but he insists on making deserts at least 3 times a week and its just the two of us here! i tried to get him to only make stuff if hes going to take it to bingo, or to church, but no... he will make cookies ( my biggest weakness) 'just because he likes to have something around to munch on'. his words, not mine. but he leaves them on the kitchen table! i asked him to at least put them in his room, but he wont. he MUST make something for his buddys he goes to friday night dinner with, but even both have them have said they want to lose weight, one of them has a heart condition and recently had to quit drinking as well. ( thats another story, at the friday night dinner, this buddy of my dad, who is usually already plowed before even getting to the lodge, now MUST not drink, doctors orders. so my dad sits there calling him shirley temple all night! i kept telling dad to knock it off, that aint cool, the man already had a look on his face like somebody torched his dog,, so i didnt drink that night myself. i told him 'look at it this way , you know you wont be getting a dui tonight! and if i can go without booze, so can he. easy peazy..but dad thought it cute to call him shirly temple. does he not get it? ) anyway back to the desernts, one day i put little notes on each and every cookie saying things like 'theres a reason alcaholics dont work in bars' he calls me fat but bakes cookies.
ok second problem, i got a look at his bank statments when he was visiting my sister recently,. no wonder he keeps yelling hes broke. he is, but its not MY fault, he spent almost half his check on quick stop grocery stores to buy stuff for these deserts nobody wants him to make!! ive tried to get him to make himself a bit of money, sell his deserts, they are very good, hes an excelent cook, but they are fattning as hell, and costing him money..
oh, i didnt mention the HUGE sack of flour he bought then stored in the closet where it clearly had black dots moving in it, he refused to toss because it was a big bag.normal people do not need 60 lb sacks of flour!! and use it in a month! we need to eat healthy and real butter aint getting it. i tried to make an old fav of my mom, brocolli ham cheese cassarole, well, HE changed the recipe a bit to be a keish in a pie shell...with butter...and cream cheese.. and God only knows what else.. hes offended when i try to make more simple, cost effective way less calorie foods.. i know he loves to cook, so why cant he cook for people that will rave over it rather than leave it out for me to have to smell and look at..id love to toss his cookbooks but i cant do that, im not a jerk like that.
so how do i get the crap food out and the good food in? how do i get him to not make food thats cooked in bacon grease? ive tried baby steps, lets use Pam spray instead of -ugh- bacon grease..nope...HELP
