Ketogenic diets, intermittent fasting (IF) and the so called "perfect health diet" (PHD) are what have worked better for me. The Montignac method is quite remarkable too. All this plans are somehow similar, based in restricted high-glycemic index carbohydrats and gluten, and rich in protein and fats.
I'm currently on a keto now and I feel my mind way clearer, am loosing weight and experimenting no trouble at all. I'm unsure of what your goals and current situation are:
If you need to lose some weight and want to see quick results while obtaining health improvement and alimentary discipline in the process, keto is for you, then you can move to another one because it's a time limited option;
if you're not in a hurry to lose weight but want long term lasting results, and you go to work/school in the morning and don't have time to prepare a decent healthy meal, then pick an IF mixed with the PHD suggestions (next thing I'll do);
if you're a girl aiming to become a cardiobunny, go for Montignac, as it's quite easy to follow, and women tend to be somehow less tolerant with more restricted diets and are prone to achieve alimentary disorders, so don't push it.
This are of course suggestions based simply on my personal experiences and somehow restricted knowledge, and some plans may work wonders on a person and be useless for others, but I have not a single doubt about the safety of this diets and I'm sure they are all worth at least a try. I'll let you some links, and the suggestion to download "The Ketogenic Diet" and "A Guide For Flexibe Dieting" by Lyle McDonald. Ask whatever you need, I know some things I write can be incomprehensible for I ain't a native speaker.
