Chunkalunkah, that's the weird thing! It doesn't seem to matter what my diet composition is. I mean, it's easy to understand that on days when I eat a big dessert or something I get hungry sooner, and that's okay. Not good for weight loss, but hey, it's what it is. But the weird part is, even if I eat foods that are super high in fruit/veggie/protein/fat/fiber--all the stuff that's supposed to hold me--it just *doesn't*. For instance, yesterday I had homemade oatmeal with milk for breakfast, pumpkin farro stew (it's chock full of random veggies and nutrients) and a half grilled cheese tomato sandwich for lunch, plus a square of dark chocolate, then an apple and half a dozen cashews for a snack, apple cider and a pasta dish with lots of vegetables and some chicken for dinner, and then by 10pm (so two hours after dinner) I was so hungry that I went and had a bowl of (good) cereal... and then seconds... and then I was *still* hungry. What the heck? I barely even worked out yesterday!
So yeah, I've noticed over the last few weeks that by and large, most days I seem to need about 1600 calories, whether I'm active or not, whether I'm eating well or not. I plan so I end up around 1400 by the end of dinner, and then a few hours later I'm still so hungry I just.need.more.food. It's very frustrating. In fact, I switched my breakfast to homemade oatmeal last month because the breakfast I'd eaten for years (frosted mini-wheats, love 'em!) that used to hold me for 3-4 hours was suddenly only holding me for 1.5-2 hours.
The ONLY thing I can think of is I'm eating less meat right now since we're hosting a vegetarian foreign exchange student. But on the tracking, my protein intake is steady since I'm eating really good other protein sources like lentils and beans and such (and still some meat, just not as much). My fruit and vegetable intake has gone way up too, and my sugar intake down.



) and you now need a greater %age of protein at each meal than you used to require. Since you've had a specific change--less animal protein--I think it's definitely worth looking into if increasing those ounces again will reduce your hunger. You say protein's held steady...Do you mean grams, rather than its percentage of your total calories? Because getting it through beans etc will also increase your carbs, so make protein a lower percentage of your diet than it was before. I was a pescetarian for about 6 years. Although I love seafood, I'd have weeks at a time where I didn't eat any. I did however eat a lot of full fat cheese, so got full from that.
Is 1600 keeping you at maintenance, or have you been often above those calories? If the latter, you might be able to lose on 1600 so getting used to lower calories again may not be necessary.
How nice if 1600 is your new weight loss sweet spot.
