I've been eating 1200-1300, averaging about 1250/day. This Saturday I started 1450/day as my first step to maintaining... All day today I have been starving! I was never this hungry on the 1250 calorie plan. I've upped protein along with calories so I'm still at around 30 prot/20 fat/50 carb, which was what I was running all along. Is it just the calorie change that is causing this reaction? I haven't added in any new foods really, just increased the same ones I've been eating...

I would give it a couple of weeks and then see how you feel. Your body may just be adjusting.

Yes, your body may be adjusting, and fighting any more weight loss. (It is going to take a while before it realizes that you are DONE losing weight now!)

Keep with the 1400-1500 for a few weeks and see what happens. Then, evaluate after that-and see if you need to adjust your calorie intake further for maintenance.

That doesn't seem like a huge calorie increase at all. If your extra calories are coming from a really sweet fruit like grapes it could possibly be making you feel hungry but a lot of people are really sold on extra fiber helping them feel full. Maybe take a look to make sure that a lot of those carbs are from high fiber foods.

For me, I've found that I will actually feel really full and a lot longer if my fat percentage is a little higher (as long as it's all *good* fats from olive oil, nuts or avocados). But then, I'm a little odd

Someone also said sometimes when you are feeling hungry, you are actually thirsty. Maybe increase your water & that might help.
