So I'm trying to lose weight. When I made this decision, I was about 170lbs. and 5'3. I researched a bit online and got that, at my height and weight, i was roughly consuming almost 2000 calories a day. It also said for weight loss, I should be consuming somewhere between 1000-1500 a day.
I'm a student, and at the moment I don't have time or the money to spare to go to a gym, or do anything beyond running around the block..
So, I changed my eating habits to try and lose initial weight before winter or summer vacations when I'll have more time to work out properly.
I consume roughly around 1000 to 1100 a day now... I'll eat a fibre granola and almonds for breakfast, tuna, soup and veggies for lunch and for supper I'll have this vegetable rice with chicken strips and lots of brocolli/cauliflower.
I feel like compared to my other diets in the past, I'm doing better at incorporating healthier choices this time around.

But, in maybe a week and a half, I've lost around 5 pounds. I feel like maybe thats too much too fast? Especially since I've read 1-2 pounds lost per week is healthy. Is it just because I've gone from such a high calorie intake to a much lower one, or the choices I'm making? I used to eat more processed/fast foods before, or snacked too much. I don't feel hungry between my new meals or snacks, but can it be that I'm "starving" myself, even if it doesnt feel that way?

I just want to make sure its healthy/normal, because i dont want to gain it all back or become unhealthy in a different way. When I have the time to start incorporating exercise more regularly in my routine, I'll up my calories to compensate and keep me energized but... for the time being, is this safe?
