I'm much the same I can't help but snack through my working day, it doesn't help that I often get bored as shit at work and they have a bottomless cookie jar and free coffee machine in the lunch room.
I agree with the above you really need to get your breakfasts down in order to set you up for the rest of the day. Ideally it should be one of your largest meals of the day!
If I'm not time poor I will make an omelette of some kind (three eggs, two without their yolks) with a filling usually consisting of some sliced up shaved ham or cooked bacon, mushrooms, asparagus, spring onions/shallots, thinly sliced capsicums etc. If I'm feeling adventurous I will add a bit of chili and sometimes peanut butter to give it a spicy satay flavor.
If I'm running out of time I will just cook some oatmeal in the microwave and top it with unsweetened yoghurt and some pre-thawed frozen berries and sprinkle with some walnuts on top. If it's not sweet enough add some natural artificial sweetener to the mix.
One snack food I will often make to have during morning or afternoon breaks is a simple tasty frittata/quiche thing. I basically just throw some bacon, ham, sliced leek, spring onion/shallots, pine nuts, baby spinach or rocket leaves, mushroom and some spices into a pan and fry until bacon is starting to brown, then chuck it into an oven proof dish and then crack about 5-7 eggs (some without yokes) on top depending how big of the bacon mixture you've made and finally top with sliced tomato, feta cheese (sometimes I use blue vein cheese but find it melts too quickly and makes it greasy but gives it an AMAZING taste) and some fresh chopped coriander leaves and a sprinkling of salt and pepper. Throw it in the oven at 370-400deg for about 20 mins or until golden on the top.
Other things I snack on are sliced up celery, carrot or cucumber sticks dipped in horseradish or peanut butter, or some other low fat low and/or low carb dip.
My lunches or dinners mostly consists of some kind of meat or fish accompanied with veges or salad. I often make large batches of things and freeze portions for the remainder of the weeks, like I would make a chicken curry or lamb stew in a crockpot etc.
I try and avoid things like white rice, pasta and bread as much as I can but I definitely don't go without carbs - my intake of coffee with sugar or the occasional cookie at work is my 'junk food', along with the occasional burger or other eating out meal with friends.
Definitely try to keep more active too, go for a run or do some more cardio at the gym if you want to lose some of the belly flubber more quickly in conjunction with eating better.
