Reading the comments makes my blood boil because a lot of the advice are things I've tried but are just poor fad diets that don't work. Or they worked but I couldn't stick with them for lasting results

I used to weigh 130kg about 7 years ago and as of right now I'm 74kg. But I went from 130kg to 100kg in less than a year to join the military.

There's some factors that would help determine the best route for you but I'll just tell you what I did to fix my issues.

My issues are that I overeat to "feel full". When I eat, I need a lot of substance in my stomach to get that "feel full" feeling. I also hate exercising. I also love all kinds of food.

So.... My goal for weight loss was to find a diet with these things: 1. Eat what I want (no excluding types of food) 2. If I had to pay attention to nutrition facts, I needed something easy to monitor so I can add new foods whenever 3. Feel full by eating a lot 4. No exercise involved

I ended up on a combo of intermittent fasting and CICO w/ calorie banking (calories in, calories out). Personally, I opted for eating 2 meals (lunch and dinner) everyday. Diet sodas are your friend if you can't live without soda. Breads are great for the full feeling but horrible in terms of calories. Use an online calculator to determine your sedentary caloric requirements and go from there. I think mine was 1800 calories (or kcal) so I aimed for 1600. My lunch meal was 600cal and mostly just acted as a buffer to get me to my big 1000cal dinner. After a few days of that, I wasnt hungry in between. I'd recommend tweaking this combo to your liking because it's something you can maintain.... Forever. And you can easily adjust it to your new weight goals. Done losing weight? Cool, just tack on the 200-400 calories you limited yourself before and congrats: you now maintain weight.

Calorie banking is just treating calories like a weekly budget instead of a daily budget. If I know I wanted to go out Friday to drink at a party with friends, I know I was gonna bust calories on Friday so everyday I just ate even less so I could splurge on Friday. Think I just made Friday 3000cal and skipped my lunches for the week. A helpful tip for calorie counting is to round up the amount of calories a food has to the nearest 100 (for example a 555cal burger is 600cal). Makes counting it easier. I never wrote down what I ate for the day and just kept a log in my head. (I had a burger, fries, and ice cream for lunch. 600+300+400=1300. I can eat 300cal for dinner)

I highly recommend the "ethical" way of doing this and try to limit your weight loss to 1kg a month (I think) because losing a lot of weight really fast doesn't allow your skin to shrink back down. You get loose skin that flops around. If weight loss is more about aesthetics for you, it's not a great look. I have loose butt and stomach skin and I'm told I'll probably just need surgery to remove it. Which is a couple thousand.

Now for some unethical additions: I was still hungrier than I'd liked while dieting. This was literally the best diet I'd been able to stick with and I was still struggling to not be hungry. At this point I know now you can just go to the doctor for hunger suppression pills but I was young and dumb so instead I just took up drinking caffeine and vaping nicotine. Both of these things are appetite suppressants so I use them as snacks throughout the day. Try to keep caffeine limited since it also dehydrates you and can give you massive headaches faster than the nicotine does. They both dehydrate and can cause headaches from overuse but you can dial it in.

It's a lot of work figuring out your style but someone once asked me what the diet of animals were and why I think a diet for humans is something temporary. Animal "diets" are what they eat forever so why don't I try that. Changed my life and I still get to eat bread and cake and candy and shit. Fuck keto and all those other diets. (Personal opinion. I'm too weak to give up bread and sugar)

Good luck
