I don't know if it's the most effective way to lose weight, but my trend is definitely downwards, and it's improved how I feel overall quite drastically. A lot of it is probably just improvement from not overeating, but I can't deny the effects.
I think my diet has been working so well for me because it's so easy to follow. I don't count calories nor do I have complicated rules about what to eat (I do try not to go overboard), only when. Dealing with the feelings of hunger has also become easier over time.
