Nuts are healthy for you, they actually have some beneficial nutrients in them. ALmonds for example help prevent cancer.......

Snacks:

• Mixed nuts -- I buy peanuts, almonds, hazelnuts, cashew nuts, raisins etc. separately and mix them myself. The trick is to hit the right nuts/raisins ratio. The other (harder) trick is to not eat the whole bowl at once. Really, really hard. A good idea is to pack small portions (ziplock bags come useful) after mixing and have only one (allright, two) a day.
  
• Veggies (carrots, cucumbers, celery, turnip, anything really) -- the problem is that they don't fill me up and I'm still hungry. Probably I need protein and/or fat to feel satiated.
  
• Fruit -- same problem, although to a lesser extent.
  
• Seeds (sunflower, pumpkin) -- the best part is that you're eating really, really slowly (so you can't eat too much) and you're really busy eating (you feel like you're eating, but you're not -- well, almost not).
  
• Homemade sorbet -- you take some frozen fruit and blend them. Simple, healthy, brilliant.

Drinks:

• Green tea (remember not to use boiling water -- it should be 140-185 degrees).
  
• Water with a splash of lemon (I also like to add a splash of coffee or a pinch of instant coffee to add some additional zing) or sliced cucumber.
  
• Smoothies -- carrots are fantastic as base; you can add whatever fruit you like (don't add sugar!). If you don't like the taste of raw carrot juice you can boil it, but that will cost you some vitamins.
  
• Almond milk (haven't tried this one yet: How to Milk an Almond (fresh homemade almond milk, easy))

i LOVE making cheddar, apple and honey wraps. I just spread a teaspoon of honey over a whole wheat tortilla, and layer thinly sliced Gala apple slices and then top with shredded cheddar cheese. I then broil it in the oven and it comes out this sweet, cheesey, crunchy, melty sort of mess but it's SO good and low in calories if you watch the cheese intake!
