Atkins worked really well for me and I lost almost 4 stone in a year and I only stuck to it 70% of the time. Unfortunately it didn't work long-term and I slipped back! Ooops!
I still try and incorporate as much protein and good “fats” as I can into my diet. I lose more on protein, which is a pain because I absolutely love carbs (could eat pasta forever!) What has worked for me best has been calorie counting (lost 2 ˝ stone on that,) and now I’m using Slimming World (which is similar to WW) and have lost about 9lb on that.
The BEST “diet” IMO is one which easily adaptable and one which you can stick to long-term.
