You aren't doing it wrong - but you aren't eating very much, so it's no wonder you're hungry a lot.
The biggest thing I would change is your breakfast - I know Special K is low calorie, because it's about as nutritionally powerful as sawdust and less filling. My personal favorite is whole grain toast, one piece with peanut butter, one piece with a no sugar added jam. I also like oatmeal with 2 tbs of organic apple butter stirred in (or 1/4 cup of Trader Joe's organic dried blueberries) and a whole wheat tortilla wrapped around 1/4 cup eggbeaters, spinach leaves and tons of salsa.
One of my big goals was to move away from processed foods, so I don't eat stuff like snack bars very often (although I always have one in my purse and in my desk at work for snack emergencies, I like the Nectar dark chocolate walnut bar). Other good snacks that might be more filling: string cheese with fruit, measured serving of trail mix (gotta be careful with this stuff, it tastes so good it's hard to stop at a 1/4 cup serving), cottage cheese, apple with 2 tbs of peanut butter, serving of hummus with whole wheat pita chips, etc.
Here is my menu from Thursday:
B - 1/2 cup Nature's path organic pumpkin flax granola, Trader Joe's non fat Greek yogurt with honey
S - small package of fresh strawberries
L - big salad I made myself - spinach leaves, sliced waterchestnuts, chopped yellow pepper, red onion, shredded carrot, broccoli slaw, grape tomatoes, grilled chicken breast, edamame, 2 tbs of Trader Joe's Asian peanut vinaigrette, a small sprinkle of cashew pieces
S - no sugar added cocoa (100 calories)
S - nectarine
S - cut up veggies - baby carrots, sugar snap peas, red pepper strips, grape tomatoes
D - I made a crockpot chicken dish with a bottle of Williams Sonoma Sicilian simmer sauce, chicken breast, served over brown rice with steamed broccoli
