Am i being realistic ?

My main question is why do you want to go that low, you'd be underweight at that weight.

Yes, that seems quite low -
According to your height of 5' 5" your ideal healthy weight is 134 pounds. Your recommended weight range is between 119 and 149 pounds.
You will be very underweight - your health may suffer. Hopefully you'll re-evaluate.

it's your body, do what makes you happy.

I agree with the above quote. From your figures I'd say you should just focus on toning and how your body looks. Don't worry about the weight - look at the areas of your body you are unhappy with and research ways to tone up those areas. Exercise and diet will of course be important and everyone here can help you a lot with improving specific areas of diets and exercise.

I've improved my diet and exercised daily for around 1 week and a half and I already feel so much better for it. A lot of it is in the mind. A lot of people would love to be your size, much in the same way you aspire to be the size of other people around you. Don't let them define you or your goals.

can somebody PLEASE tell me are my goals realistic or not,instead of judging me

They aren't judging you, they are telling you that your goal is unhealthy. However, I agree that it's your body so at the end of the day it's your choice not anyone else's. Another user (or users) have mentioned weight training to lower your body fat percentage which is a great idea, you might find the reason why you were "fat" (I use quotation marks since I obviously don't know what you looked like etc) was possibly (once again I'm assuming things) because of a bad diet/lack of exercise therefore resulting in you having less muscle and more fat, it would be worth trying weight training since nothing ventured nothing gained right?

Edit: In answer to your original question, you want to lose 48lb in 7months, which would potentially be possible if you could continuously lose nearly 2lbs a week, but (as I've seen over the forums) a lot of people say the less weight you have to lose the slower it becomes so don't become disheartened if you don't hit 48lbs in that time frame

my lowest weight was 130 lbs and was still fat. trust me. even people still called me fat. and all my friends are the same height as me and around 110 lbs and looking great and sexy.

Possibly. But I'm not encouraging unhealthy behavior.

And anyone who told you that you were fat at 130lbs is an *kitten* and not someone you should have in your life.

If you wish to change body composition my advice would be to look into lifting heavy weights. It will give you an amazing body even at 130lbs.

i reccommend starting strength training ASAP check out the new rules of lifting for women. don't severely restrict your calories, try to stick to about 80% clean foods and 20% of whatever else you'd like with the proper effort put into strength training, even if you don't get as low as 110lbs, you will look amazing!

I don't have experience with this myself, but this is what I've seen and heard from my MFP friends. How much you lose depends on how dedicated you are to your diet, cardio, and strength training. However, once you get down to those last 10-20 pounds, it can be very difficult to lose that weight quickly. So while in theory, you could lose that weight if you lose 2 lbs. a week. But in reality, it probably won't be that easy or that quick. You have to account for plateaus, which do happen, and the slowing of weight loss as you get closer to your goal. Or so I've heard.

My current weight is 158 lbs ( i'm 5'5 ) and i want to lose 48 lbs in the next 7 months.
is this achievable?

On paper it may be realistic, but our bodies don't always act the way the paper graph says, so it's probably not.

2lb per week will be achievable some weeks, but not all, and if you are the type to get hung up on numbers failing to achieve the 2lb may get you so dissapointed that you give up.

I am 5'5'' and current;ly at 130. I want to get to 125 but iIplan to do it through strength training rather than just fat loss, which probably means i'll look 125 but weight 130 or more. Look into lifting, you are probably "skinny fat" like me.

I am 5"5 115, aiming for 110 (the weight I formerly was). Though in saying that, I am EXTREMELY fine boned, so weight looks a lot more dramatic on me than other girls who are my height.

my lowest weight was 130 lbs and was still fat. trust me. even people still called me fat. and all my friends are the same height as me and around 110 lbs and looking great and sexy.

Maybe try some strength training? Sometimes people don't necessarily need to lose a ton of weight, they just need to decrease their body fat percentage and they'll look a ton better. It's not necessarily about a specific number (honestly, for me if I have a number in my head I'm never satisfied when I hit that number - it's all about how I look and feel and being healthy).

agreed!!! strength training is so important!!!!

can somebody PLEASE tell me are my goals realistic or not,instead of judging me

NO. Your goals are not realistic.

My current weight is 158 lbs ( i'm 5'5 ) and i want to lose 48 lbs in the next 7 months.
is this achievable?

hey
im 5'5 and im at 133, was 140 a month ago, i want to lose about 10lbs but no more then that, and i think i know here your coming from with the 130 and still feel/"look" chubby. i think a 48lb drop is way too much. just tone up. and it will all fall into place. im doing P90X right now and it working for me!
