In short, yes.

When I first started eating primally, my calories dropped super low because of the high satiety factor of fat. I was not used to eating that much fat and that little carb. Over a month I began to be able to eat larger quantities of food as I became accustomed to eating more fat.

I was also eating different things. I didn't have desires to eat good size portions of some things that I never ate that much of. For example, pre-primal I ate cereal (more than one "serving") for breakfast almost every morning and never felt stuffed.

Eating an egg and a serving of sausage though filled me up past comfortable. Now I can eat two eggs cooked in butter, and probably two servings of sausage (if I wanted that much sodium) with a teaspoon of maple syrup and maybe even a glass of milk. I have also eaten 1,000 calorie breakfasts before in my year of primal eating.

Depending on how long you have been eating this way, you may just need to acclimate to the food and fat level. I wouldn't worry about the calorie amount too much for now, you will get hungry eventually. If you feel like it should be improving, maybe you need to make the food you are eating more appetizing or try more calorically dense foods.

Sheesh, I know what you mean! This weekend we are working at a homeschool conference and I have no desire for the candy that seems to decorate every vendor's table. I ate a hearty breakfast before going, a cautious lunch at a fast food place, and a huge anniversary dinner, and I still didn't manage to break 1000 calories.

It's easier at home where I can track the calories right after eating lunch and know how much to shoot for at dinner.

And I *have* to track calories, or I'd be consistently running about 700 to 900 daily, which I'm told will stall my weight loss. Weird problem to have -- I don't think I've ever had the problem of having to eat *more* than I wanted... at least, not until I started eating this paleo/primal way.
