Best bet is to find something you can live with for long term..like cutting portion sizes and just not eating the "junk" you know you're not sup to..more veggies, more water, more protein.
I personally, have excellent results restricting carbs. I am not really overweight, I have vanity lbs to lose..and two weeks into an atkins/paleo diet I have lost 8 lbs and have never gone hungry for a minute. In fact, my appetite has decreased to the point wher I have to remind myself to eat sometimes. If you have more than a few lbs to lose I have seen people lose as much as 15-18 lbs their first two weeks. BUT, its not really a diet you can go on, lose the weight and go back to normal and keep it all off. You will gain a few lbs back if you quit (some people say all of it, I never did when I returned to eating carbs, I still had a net loss) ..however, most people can increase their carbs quite a bit to maintain their weight and still have the things they missed. Plus, it really clues you in to the carbs you eat every day and what you can live without, and what can be an occasional treat. I find I can have an occasional cheat day and eat more carbs than I should without getting out of ketosis. There are lots of swaps you can do for every day foods and meals...plus it has the added benefit of improving a lot of health "stats" including cholesterol and blood pressure.
