Low Calorie "filler foods"?

Anything with high fibre, high protein. Fibre = 0 usable calories/gram, protein = 4 cal/gram (lowest)

Both will help get you enough to not leave you hungry but keep calories down.

My preferred low calories snacks/meals:

Fat Free Cottage Cheese: 2 cups = ~300 calories (depending on brand), 55-60g protein. Add some fruit and/or veggies and it's a nice quick meal.

Beef Jerky/Turkey Jerky/Grilled Chicken: High protein, low calorie (per volume) and tasty. I grill up chicken breast and add to a salad (meal) and/or just dip in a low calorie sauce (snack) like mustard, salsa, etc.

Fiber One/All Bran+fat free milk: Fairly high calorie due to high carb content, but relatively small amounts (1 cup) fill you up pretty good due to the very high fiber content.

Veggies. Yes, veggies. Lots of fiber, very low calorie. A favorite snack of mine is baby carrots, tomatoes and broccoli dipped in salsa (I love spicy foods).

Avoid *anything* with fat of any kind (other than the requisite dietary requirements!) because fat has ~3x the calories per volume that protein does, and ~2x that of carbs.

Kimchi, grape tomatoes, and dill pickles.

eggplant, squash (zucchini, spaghetti, butternut). You'd be surprised how much you can eat for very little calories. Shirataki noodles. Spinach salad w/ balsamic vinegar. Salad w/ salsa. Peppers... Veggies!!

NCNOLE....."Pickles".. I used to eat them all the time, until I realised how much salt I was taking in (cause you can't eat just one!) I made the switch to cucumbers... crunchy, low cal, no salt, and filling. I hear ya though... mmmmmmm PICKLES

Sorry NCNOLE I meant that for the post from eKatherine.

Bulk out or replace calorie dense foods with lower calorie ones that perform similar functions on the plate.

I use butternut squash to roast instead of Potatoes. Bulk out mashed potatoes with swede/rutbaga, carrot etc etc.

I replace/bulk out rice with grated/blitzed cauliflower that's lightly cooked so it retains a little texture.

I don't crave them or consume mass quantities. One fresh pickle at a meal is the most I eat. I can see it might be an issue for someone who is salt-sensitive. But a small fresh dill pickle has hardly any calories, and may be just what is needed to balance out chicken breast or fish.

I like mexican so I organic full circle refried (but its no fat)black beans vegetarian which is beans, water and salt only, I add organic lemon juice to this, add garlic, minerals of sea salts, even some dried onion if you want...it just is very filling. The whole can is 360 calories. eat 2/3 of the can and it meets your limits. I found going high fiber just was so satisfying in a way I had not expected. just keep it below 30% of your total intake so you keep digesting vitamins, minerals etc. my other thing is organic old fashioned oats. I am not big on hot so I add cold water to it, then some liquid stevia, some cinnamon and sometimes nonalcohol vanilla for a sweet treat. You can always add in cubed apples or other fruit if you want that, too.

I use a bag of pre made salad mix. I just eat it out of the bag like potato chips, and the calorie count is almost nil.

I think both raw and cooked non-starchy vegetables should be a big part of any dieter's menu.
