All of them, put some restriction on your overall intake (and therefore calories). This is dieting 101, if you haven’t managed to get yourself into an energy deficit then no amount of super foods will do the trick.

There are people who have succeeded on every diet vogue in books and on the internet, you’ll never hear of those that failed, of which you can be sure there are plenty.
Find something that works for you, your lifestyle and tastes. It still won’t be easy, it will still require consistency and discipline, but setting your diet up properly will have a profound effect on your results over the long term.
