How have I lost 10 lbs in 4 days?

I'm 5'3" and am 16 years old. Recently, I'd gained a little weight, so I decided to go on a low calorie diet using this app called "MyNetDiary" on my iPhone. I'd also read online that, for my height and age, a good weight to be at would be between 115 and 120 lbs, so I decided to aim for 118 lbs as a beginning goal and have been thinking about trying to reach 116 after I've reached it. The diet that I've been on has restricted my calorie intake to 1, 298 calories per day, and doing this was only supposed to make me lose 1 to 2 pounds per week. The lowest amount of calories that I've eaten over these past few days was 844, but I woke up later on that day and ended up skipping breakfast because of that. On every other day, I've eaten 1, 000 calories or more. The only differences in what I've been eating and drinking are that I'm drinking more water, eating slightly less, and am eating/drinking no sugar. I'm still eating carbs and have not even been exercising to lose this weight. I've been trying to diet in a healthy way that would be able to stick even once I stopped dieting. I have no idea how this happened and would like to know if anybody knows how this could have happened. At this rate, I'll reach my goal within the next few days…

Can my iphone still be tracked?

So my iphone 4 was stolen yesterday. I called my carrier and they informed me the sim card must have been removed or destroyed.

I've done a bit of reading on how thieves try to erase all the settings on the phone so they can't be traced down.

Is there any way to track my phone if the sim was removed and or if they erased all the info on my phone?

I already contacted the police

Best Camera for my situation?

I have an IPhone and an 8 year old camera that was like $50, and thats all I have to take photos with. I decided that its time for me to get a good camera and really capture the moments in life beautifully. On Facebook I see my friends and family posting these amazing clear photos, and I want to get good results like theirs. They are no professional photographers, nor am I, and don't know much about photography or editing. I'm going to Europe in a couple weeks and want to take really good quality, clear pictures. I don't want a big bulky camera, just something that will give me good clear pictures. I don't want to spend more than $400. I would like to frame some of these pictures, so I do want the best quality. Again, I'm not professional and don't know much about photography.

I think i need a new iphone, will apple replace it without applecare?

My phone won't charge unless its off (dock connector/ logic board problem) and the screen flickers (obvious hardware issue or might be logic board too) i have never dropped the phone and there's no physical damage, it has to be a issue the phone was shipped with as its only 3 moths old, i'm also running iOS 7 Beta 2 without a registered UDID.
First of all will they even service the phone without it being registered? And will they replace the phone without applecare (it is less than 1 year old and not physical damage)
