I've read a bunch of your posts now in this thread, and you continuously assert that you are somehow a special case, yet from what you write, you behave *exactly* like the typical diet-failure case.
1) You claim that it is impossible for you to lose weight. This is not true. I'm sure it's harder for you than for most people to lose weight, but by claiming it's impossible, you've resigned yourself to useless victimization.
2) You claim that since the long-term results are so bad, you might as well give up already. It is true that many who "go on a diet" return to their original weight afterwards, when they resume their original eating/exercising habits. This is obvious, it is exactly those habits that made you gain weight in the first place. Most people fail to achieve permanent weight-loss, because they fail to realize that the changes to their eating and exercising habits has to be equally permanent. The ones that succeed are the ones that realize this.
3) You say you have such a busy schedule that you don't have the time to lose weight/eat right. That's fine. It's perfectly ok to value your job and your family higher than your weight, and for you to choose to spend time on that instead of yourself. But be honest about it. Don't play the victim by blaming all sorts of other things. "I don't have time to exercise because I'd rather spend that time with my family" is perfectly fine. "I don't exercise because it's impossible for me to lose weight" is not fine. It's a lie.
4) You say you did maintain a strict diet and exercise routine for 8 months and that you hated it. Then you're doing it wrong. To achieve permanent weight-loss, you have to change your lifestyle permanently. Noone can live a lifestyle they hate, that's just a giant setup for failure. You have to change your diet and your exercise habits into something you actually enjoy. Talk to a doctor or dietitian to get help finding what's right for you. You can get inspiration and ideas from random idiots on the internet like me, but don't trust us, you have to find out for yourself what works for you.
5) You are very frustrated by the weight-loss industry. That's understandable, but not very useful. The entire weight-loss industry is one giant scam. They cannot help anyone lose weight, and they're not interested in it either. Ignore it. There are no magic pills or diets or exercises. There is only this: Eat less. Exercise more.
Finally, start small. Pick one thing to change at a time. Drop sweetened beverages for mineral water. Switch fries for carrots. Eat fruit instead of candy. Just do one small thing at a time, and only do things you are comfortable with sustaining.
