I'm kind of at a mix of stage 1 & 2 - I drink as much water as possible and only eat if I get hungry - I also watch my portion sizes. I generally stick to pumpkin seeds, sunflower seeds and almonds, but to be honest I don't eat many nuts. If I get hungry I'm more likely to have a small piece of fruit ( ie: plum, nectarine or a handful of cherries) or a boiled egg. Eggs are really good in moderation, they are high in protein and fill you up nicely.
Hope this helps
