My tips:
1) Only drink water nothing else ever.
2) Only eat healthy food as much as u want.
3) Don't buy food you like to eat, buy food you don't like to eat or don't like even remotely at all ( prevents overeating big time )
4) When u do shopping for food, don't buy anything else but healthy food and only go buy stuff if you ate and are stuffed.
5) prepare all your own food.
6) Cheat day is a myth, never cheat day ever.
7) hold at every moment water with you, so u can sip on it all day long. ( get ready to piss a lot ). It's your junk food now.
8) create a goal ( sports that u wanna reech in a year or two or something ). So u have something to work for.
Now you get home.
Whenever u crave for soda or chocolate etc, congrats u got nothing so u can't cheat other then eating carrots or whatever u got on healthy food. And if u get hyper, its time for a run.
Now reprogram yourself mental by.
1) This is what's left of the world food supply, there is nothing else then this. Food shops no longer exists. They are all poison. U are deadly allergic in this new world towards all foods besides the shit u got. And u will eat all that garbage with happiness because u are still alive. Basically start to believe in some bullshit story u made up.
2) Never ever cheat. Party's? don't eat or buy a salad with the most disgusting piece of fish on it.
3) Start doing something else a hobby, u don't like something? good start doing it and see where it ends. Go on clubs or hobby's like fitness and do simplistic training as u will be out of energy at the start, but u will feel beast mode half a year in and super healthy.
6 months later.
U never took a shit so good, u never felt so energetic. U never had issue's standing up in the morning so easily, u never had it so easy to sleep all night long without issue's. I never felt so good basically in your life. Everything you eat will taste godly, even a simple thing like a carrot will have 300 flavors that u never tasted before in your life, and god u are craving that dam carrot at the end of the day.
U got the feeling u are in total control, and u can eat some stuff as u no longer really crave it and can control it.
WRONG
U will start eating again, get fat, get non social because fat etc etc etc. U did it before u will do it again, Thread it like alcoholisme because that's what it is times 10. It's a drug.
U NEVER CHEATED.
Good job bro, now ram another 3 years of that diet towards it. U gain some little bit of weight as your body starts to crave the healthy good a bit to much? time to shake things up and start to eat shit again u don't like.
Congratz, u now eat and love everything if you made it and your life has changed.
Losing weight = changing your mental life style. Your body will change with you all day long. It's a machine and nothing more.
Anyway i personally don't really believe in surgery. Because it doesn't adres the real issue behind you overeating. U will just find another way to abuse the system and push it forwards again.
However if you are mentally impacted by something that u can't move away from, see a therapist and start to count bunny's on a piece of paper. It's probably the reason u eat so much.
Anyway.
Good luck.
Edit my story:
I became overweight after pushing myself through university because of barely having to move. Eating like shit and personal issue's like family that was tearing me apart through sickness really took a toll on me.
I never was much of a sport person or cared much for it, never could drink water as it was disgusting in my view and didn't like healthy food because no sugar in it. It all taste like shit to me.
However at some point i needed to push a bit further and make changes which resulted me to.
drop the weight i gained over years in a matter of half a year, i did a full blown traithlon after 4 years of training and half a triathlon after 2 years of training.
That's 4km swimming, 180km biking, 40km running. ( full one ).
It's absolutely brutal to the point i trained around the 200km bike rides every other day in my free weeks i had. I drank at some point more then 10 liters of water 2-3 galon, because i was just consuming so god dam much sweat in the heat. And had to plan for "daylight' because the days just where not long enough for me biking outside.
Every day i felt like shit and didn't wanted to bike. That was my greatest day of progressing. Every day i felt like a god and wanted to push forwards it never went well. So whenever i don't want to do it. I know my body is ready to do just that. ( part mental also )
At some point i signed up for this mudmaster event, which was 20km through the mud ( basically militairy parcour ) it was the longest distance. I saw everybody half dead near the endline while i was just showering, picking up my stuff and walked to my car to realize i lost my keys.
Well how about that? no keys? No problem i just ran back 10 fucking kilometers to my house. Get my reserve keys and walked back.
However as the autist i am i did pushed a bit to far when is started to do 300km training and started to plan daylight as my limiting factor ( lol ). Stand up when day just starts, come home in the evening when the sun goes down ( biking mostly ).
It was so bad that i couldn't sleep anymore and was just sitting up whole nights because of it. ( yea lol train 12 hours can't sleep ). only thing i ate was shit like egg white to recover and salads with tuna and chicken with water. Next day came and 5 hours of fitness.
After horrible abuse of my body, i ended up crashing through a steer that snapped at 60km a hour downhill which ended up my skin being stripped of my arms, which put me down for half a year and that's where i sit at now. everything is recovered now tho to the point i am just being lazy.
In short.
U can do whatever u want, your body will follow. It's extremely adjustable piece of equipment that can make you a olympic sport or super obsessed and yet it still survives.
I can do the disciplined nutrition for sure, but exercising has been tough on me. I have an exercise bike and I can do 30 minute sessions with it while listening to Thom Yorke's Anima. The thing is I just started and I don't feel a weight loss. How long did it take you to lose ~30 pounds?
I did 12 hour training sessions outside in the ice cold rain with headwind for 6 hours and when i ate a fucking bag of chips at the end of the day i gained weight. And felt like shit the next day of training because for some reason body knows.
All that garbage is massive massive amounts of fat u shove into your throat. 30 minutes of biking does nothing else then warm up your muscles and start feeling alive.
U gotta train a god awful amount to burn shit food or drinks.
U should cut that shit out of your life directly and never even touch it. It's all kid food. See it like drugs.
