I don't lose any weight!!!

OP. What you are currently doing is not working. It seems wise to take the advice offered, if you are unsure speak to a nutritionist/doctor.

but I don't need more than 900 cal. I don't mean to starve my self like you saying. but it's like my daily needing!

Clearly if you haven't lost weight for 4 months, it's not. Start with 1200 calories a day and see how you feel from there.

I checked your diary before I read all the comments, but I had to go all the way back to the 22nd to find a day where you logged.

MFP works if you use it, Try to log everything you are eating for the next week, because even though your goal is 900 calories (which I agree is to low) i wouldn't be surprised if you are not even meeting that.

Focus on getting in proper nutrition and use MFP logging to make sure you are getting enough protein, good carbs and fat and then evaluate from there.

ran your numbers on http://www.fat2fitradio.com/tools/bmr/ and even if you are sedentary then you need at least 1400 calories.

Keep everything else the same but add in one 15-20min HIIT (High Intensity Interval Training) session a week

NOT this - you are not eating enough to fuel your current activities let alone more activity.

Also if you have time, have a read of this, its a bit long winded, but may help you.

one more question; if I ate 1000 calories a day, how much I should burn during workouts? or will I end my day with those 1000 cal?

If you eat 1000 calories a day you should not be doing ANY workouts. You need to eat most if not all of your exercise calories back. So if you burn 500 calories working out you need to eat 1500 calories (although the starting point of 1000 calories is still too low).

ETA: please look into the article sniperzzz posted as I really think you need a diet break.

I commend your ability to stay motivated for so many months without seeing much change. That really shows good commitment and I think that will carry you a long way- so long as you begin eating a bit more. I know many people have said so already, but aim for 1200 cals to begin with, if netting 1200 is too hard right now.

For instance, you could add 2 tablespoons of peanutbutter (190-200 calories) spread on a banana (100 cals) for a snack and there you could have an easy 300.

Or, if you're looking to add something more substantial you could saute some veggies (mushrooms, onion, zucchini, bell peppers, etc) and add it to a cup of rice for 300 calories.

Anyhoo, my point is that you're doing a fantastic job in regard to making this kind of commitment to reach a goal- which can be the hardest part. And, since you haven't noticed any change yet, adding some more calories certainly won't hurt to try for, say, 2 weeks.

I wish you the best of luck!

you got me wrong!! I mean I feel full when I eat 900 cal and you guys say that's wrong. so If I eat way more calories beside doing the 30 days shred by Jillian michaels. will that help to lose weight? cause I've not lose ANY weight since 4 months (since I started)

If your 900 calories represents an excellent nutritional balance (which is hard to do without effort), I would imagine the problem is that you're not exercising as hard as you think you are.

Are you doing 45 to 60 minutes of cardio 5 to 6 times a week with your heart rate at an intense level for most of the workout?

I would also do a bit of strength training, not to lose weight -- it won't help that much -- but to have a better rounded program.

It also couldn't hurt to see a doctor or registered dietitian about the nutrients in your diet.

As you are very short -- 4' 10" -- I would be wary of increasing your calories to the 1400+ level some people are discussing, at least without knowing the true level of your exercise efforts and how much you weigh now.

Look at her diary. There is not an excellent nutritional balance.

AGREED!! Eat, woman, eat!! Even a tiny person like you needs more calories than you're consuming. You won't lose weight until you start to fuel your body properly--plain and simple. Best wishes. :flowerforyou:

Please do not equate your calorie levels to this girl. From your prior posts you are older and totally sedentary - she is an 18 year old girl who is very active. Telling her to inccrease the intensity of her workouts is terrible advice.

She's also quite short. I don't know how much she weighs. Some people said without knowing her height that 97pounds was too low. That was wrong.

I assume an 18 year old is a grownup. And I did suggest she talk to a specialist. I added other qualifications that clearly you did not absorb.

If someone eating low calories does not lose weight, it 's probably because they miscalculated either their calorie burn or their calories consumed: It's that simple. As has been pointed out numerous times, starvation mode is not an easy event to trigger.

Don't get discouraged... shake up your workout and focus on core body movements...

Listen to what has been said... you aren't eating enough! You may feel full on 900 calories and feel as though you don't need anymore but you do.

900 calories plus exercise is dangerous and not enough to sustain anyone. I suggest you go see a doctor to discuss your nutrition with.

From reading another topic by the op, she seems to have some interest in a diet called the SGD, skinny girl diet, or somesuch, which advocates eating below 1000 calories.

That is pretty much a pro ana diet - hopefully the OP will listen to all the advice here.

Switch your brain from "skinny" to healthy...i think you will be better off...

If you have been eating low calories for an extended period of time, it may be a good idea to eat at maintenance for a few weeks,before returning to a deficit. Then gradually taper them down sensibly, until your losing again. 20% bellow maintenance is a good start.
