It's hard to make any conclusions about what your actual physique is like based on your hip circumference. If this were your waist circumference I would consider 98-101cm a serious matter, but the hip circumference is inherently supposed to be greater than the waist circumference, so I really can't make any definite statements. Because glutes make up part of the hip measurement, any growth in the glutes could result in an increased hip measurement. So it's not necessarily a bad thing if the hip measurement increases.
I know that your BMI is almost exactly 22.5, which is right in the centre of normal BMI. You're almost the same height and weight as me, and I'll tell you now, it's not a bad height and weight to be at.
I will tell you this, however. Being of the same approximate height and weight as you, I can say with confidence that 1,000-1,200kcal is not ideal. Even if you want to lose bodyfat, you should be consuming more than that. 2,000kcal/day is actually likely to give you better results than your current, more strict approach. The body doesn't like being fed less than what it needs for maintenance. In terms of losing FAT (not just weight in general), I'd feel safe to argue that it is better to take only a small caloric deficit than a big one. Say you need 2,200kcal/day for maintenance (for argument's sake). Standard advice would have you consuming about 500/day less than that to lose fat, so that evens out to about 1,700kcal/day. Now, within that wiggle room, you might justify to youself that 200kcal either way won't make much of a difference - it's ONLY 200kcal, anyway. I would argue that for longterm (and perhaps even short-term) success, doing a 300kcal deficit one day would actually be less detrimental to fat loss than a 700kcal deficit on that day, because the further you steer from maintenance, the more likely it is that your body will cotton on to the lack of food entering the system. And in that event, the body won't respond by saying: "Good work, Fruzsi, I'm so proud of your initiative to get in control of your shape." Instead, your body will more likely respond by saying: "I'm not getting enough food, so I can only assume there's not enough food in the environment. Better send all energy received to the fat cells, so I have more to fuel myself with."
So, avoid eating above maintenance, but also avoid eating drastically below maintenance.
