HELP!!!

So it’s the new year! I wanna lose hella weight this year and look hot naked. I don’t feel confident in the body, but even worse i don’t feel healthy. Working out isn’t a big problem, once i get in the habit, but sticking to a clean healthy diet is HELL for me. It’s so hard. I love to smoke weed so i get the munchies and i never have any healthy snacks lying around but whatever. Basically i wanna get on an easy diet, good workout plan, and see improvements in my body. Anybody got any tips?
