Simple isn't easy. Losing weight is simple, just eat less than what your caloric expenditure per day is. It's still hard as fuck and just telling someone who has issues with eating "just eat less, it's simple" is not helpful at all.
Going cold turkey and never doing X is the simple solution for any addiction, now get addicted to anything and try that out...
I agree it is not easy, but for me it is better to approach it simply. It may be that the best way to eat less for an individual is to fast, or to eat five small meals, or whatever program they use. But advising people that it is next to impossible has never worked.
I have been addicted to cigarettes and alcohol. Going cold turkey is essential for getting over the addictions. Never doing them again makes relapse unlikely. These are simple facts. AA says you can't really achieve independence you have to replace it with meetings and prayer. I say you can get over it. And I have experience with people who go back and forth to AA relapsing, and so how will they ever get free?
