A little...(maybe a lot) discouraged...

Read this article: http://www.myfitnesspal.com/topics/show/3047-700-calories-a-day-and-not-losing

Basically, if you're eating REALLY low calorie, you have to make sure you NEVER binge... because it will be stored immediately as fat. I, personally, prefer a more balanced approach to weight loss... eat at the higher end and lose slower, because whatever I do I want to be able to do it forever. I have a hard time on days where I have to stick to my 1640 without any exercise calories to eat. I can't imagine eating 1000 or even 1200. I eat around 2100/day and I've lost over 7 lbs in the last 4 weeks.

Oh honey you're not eating enough at all, had a quick look at your diary and some days you're not even hitting 1,000?

I know you're feeling discouraged - try your best to up your net calories to 1200 a day, cut out the diet sodas (so bad for you) and drink lots of water, then do your weigh-in a week from today and see how you get on. You can do it, but not if you starve yourself. It takes a long time but it's worth it. Also fill yourself up on more fresh food if you can, not that it makes a whole pile of difference calories-wise but you'll feel so much better if you try and cut back on the processed stuff.

Best of luck to you, YOU CAN DO IT x

Eating under 1200 calories will put your body into starvation mode. You are not eating enough and when you do eat - you are eating **** like KFC.
You need to start cutting the crap, eating a reasonable amount of food i.e. 1400 calories - upping your protein and exercising.

There is no way your body - especially if you are bigger - can sustain itself on less than 1000 calories a day. What is happening is that your body is taking every little tiny bit of food you give it and turning it into fat as it is panicing and trying to survive.

If you are going to start exercising you will need to up your calorie intake even more than 1200. I go by what MFP says, eat back my exercise calories and am loosing 1.5-2 pounds per week.

THIS!

To up the calories to 1200 and add exercise without eating back at least most of those calories you're just in the same cycle. Aim for a net of AT LEAST 1200.

Have you calculated your BMR? If you weigh 400lbs, and are average height (I used 5'6") your BMR is 2500+ calories. So if you ate 2000 a day with some exercise you could probably easily lose 2lbs a week. So, as everyone has said, being as big as you are, you need to eat more to fuel your body. Make those 2000 calories count with healthy foods and you'll be full all day and lose weight. Good luck on your journey.

THIS THIS THIS!!!!!!!!! Plus some exercise, even if it's just a walk around the block right now. 1200 calories is not NEAR enough for you to maintain a loss. I started at 215 and was at 1500 calories WITH a deficit. You can't starve yourself thin, and 1200 a day will cause you to stop losing. That thing about making the 2000 calories count is spot on. veggies, fresh meats fish and dairy, low sugar, 2-3 fruits and you're good to go (and watch your sodium, and LOTS of water) I agree that you need to see a doctor for guidance, but take even what they have to say with a grain of salt. Even they can be misguided sometimes.

You may not be eating enough, yeah I know weird huh? I plateaued for like 3 months and then increased my calorie intake from 1100 to 13-1600 on top of exercising and it worked.

Make sure you see a registered dietician as well.

Hey hun!
Just thought I'd add a tid bit from weight of the nation (new hbo documentary). I thought it was interesting that once we are obese as adults, our brains fight losing weight due to a drop in the hormone leptin. SO just remember it is a fight the whole way, and sometimes your emotions are a bit out of your control. Also...what everyone else said: 1200-1300 calories and cut down the sodium. If I eat a lot of sodium...I retain water for about a week.

I don't think 1200 cals will do it either. You can try it, but just keep in mind that I am guessing you should be eating around 1800 just as a total guess. This is a situation where less is not better.

Everyone is telling you to eat more, but they are not telling you why. The reason is that you are starving your body, and therefore it is holding on to everything you put into it in a survival mode. The more you feed it, up to a point, the more willing it will be to let go and allow itself to get out of survival mode and release the fat.

If you go here www.fitnessfrog.com and calculate your TDEE, and then subtract about 15 to 20% of that, that is how much you should eat daily to lose a lb per week. You might have to make small adjustments, but it should be pretty right on. Give it about a month or so. And, you can increase your intake slowly. Like 100 cals per week until you get up to where you should be. You might gain weight at first, but it's just water don't worry.

Good luck.
