Tiki, it is two things for me... one, getting as much food as possible for my calories, and two, embracing hunger. Eventually, if you embrace and power through the hunger sometimes, that is when you are winning... your stomach and body will adjust.
For example, a typical food day for me would be:
B-fast:
Total calories: ~80
1/2 cup fiber one w/ 1/4 cup milk split between the cereal and my coffee. I do use sweet'n'low for both the cereal and coffee, I can't stand either without!
Lunch: Total calories, ~350
Dinner sized salad w/ romaine, cucumber, red onion, and 2 Tbsp Light done right three cheese ranch (my fav!), about 100 cals. Whole wheat flax seed pita (60) spread with one laughing cow light swiss wedge (35) and about 1 oz of ff deli turkey (30-40), ~130. Fruit, either an apple (30) or 10 or so medium strawberries, and 1 4oz liveactive cotttage cheese (90).
Dinner for me varies. Sometimes I will make fat free spinach dip (w/ ff sour cream, frozen chopped spinach, and spinach dip mix) and have one serving ff pringles (70) and a whole mess of raw veggies (~30 depending), for a total of 200. Some form of lean meat that equals about 250 (8 oz chicken breast or fish, or chicken livers, or 96% lean ground beef), and maybe a veggie for a side, and even a baked potato (~100) w/ ff sour cream and parkay spray.
I love the fat free promise spread (5 cals), and cook almost everything that I eat in a few sprays of cooking spray and a non-stick pan.
I drink a minimum of 64oz of plain water. I hate it but I choke it down. I do drink a diet soda with lunch most days, and sometimes some caffeine free diets in the evening, but I always choke down the plain water.
In the mid-afternoon I sometimes go steal a few almonds from my boss, 6-8 or so, or snack on veggies. I bring a big soft-sided DVC cooler from home every morning that is filled with healthy things (and an icee so it can stay at my desk) and if I do get hungry, I am not beholden to anyone else, as well.
And I almost always eat a nighttime snack, for me at approx 9-10PM since I go to bed around midnight. I am a snacker by nature, so I leave 200-300 calories from dinner in order to do this without guilt. Some of my favorites include a bag of 94%ff orville popcorn (~200), or a 100 cal ice cream, or even a glass or two of wine (1 8oz glass = ~150) or a beer or two if I am not really hungry.
Oh, and I go to the gym about 3 times a week during lunch. This helps keep me honest too... once I have put in all that darn work, it is harder for me to undo it with food. And I DON'T EVER let it give me license to eat more. Sure, it burns calories, but the more calorie deficit I create (assuming of course I am eating balanced, getting nutrition, and staying around 1100-1200ish), the more I will lose.
You would be surprised, but after doing this for as long as I have, I actually track my food to be sure I am getting enough!
