Weightloss hindered by body's 'homeostasis'?

I am wondering if a healthy body naturally works towards some sort of state of homeostasis; or rather it works towards maintaining "ideal weight" or "set point." I am currently struggling to lose weight perhaps because of this.

I am currently 23 yrs old, 5"5' and 137 lbs. I stay active with cycling 50 miles/week and HIIT or strength training 2-3 days/week. Over the past year I have gained about 10 pounds and a few inches as well (I have a very whole foods style diet; lots of oats, nuts and protein attributed to the gain) However after some consideration, I like how I looked and felt (lighter & more graceful, vs strong) at 125 lbs. So I would like to slender down a bit, and i recognize I must decrease my caloric intake.

For the past 2 weeks I have been trying 1700-2000 calories per day (still with my exercise routines), but my body just will not have it. I am very physically uncomfortable if I don't get in an extra 300-500 calories about my decreased amount. Perhaps my body is used to the food, OR it is resisting eating into its fat and muscle– this resistance being the homeostasis. If my body is naturally signaling me 'NO calorie decreases!', then I want to listen to it. That's my holistic mentality. But then again, maybe it's my holistic mentality that all too in tune with the body, and I should just suck it up and eat less.

The only other thing I can think of is the exercise is keeping me hungry... maybe I should replace my lifting and HIIT with longer lower impact cardio sessions....... (not as fun).

Thanks for the help! xx

    You may have more success getting advice if you open your food diary. Are you logging what you eat?

    your numbers could be off, or you may just need more calories. IMO you should up them see what happens.

    If you simply didn't have more than 1700 calories of food available to eat, your body would "just have it".

    I didn't word this appropriately or explain fully.... I've had maybe 3 days of this lower intake, the rest of the days have only been "trying" and then eating my regular intake (which is probably avg. 2200, but I wasn't counting).

    I've only been logging on this site for 2 days. I might make it public soon which would help my question.
