Tried everything, STILL NOT LOSING WEIGHT!!

You are 5'6", 210 lbs, exercising regularly, and you are only taking in 1200 calories? You need to eat more. Without knowing your exact activity level I'd hafta go off of a guess of around 1900 calories for you.

Eat more.

Ok, so assuming you are "lightly active" your daily calorie needs for maintenance are around 2400. Your BMR seems to be around 1800. So 1900-2100 calories is a good goal for you.

I'm going to agree that you might need more than 1200 calories, especially doing anything by Jillian Michaels.

^This. I'm 187lbs, I only workout 4-5 times a week and I eat 2000 calories a day. You need more food!

So throw some Olives on that salad, and maybe an egg, use regular dressing and poof you have just raised your count substantially without adding hardly any food.

How long have you been at this?
Eat some more like people suggest, but eat good stuff! Do some training with resistance bands!

EDIT: Also weight watchers tends to be rubbish, My mother and my gf have been on it for years and only had temp gains!

Oh wow, that seems like A LOT of food! I never thought you'd have to eat that much though.. I can some days barely make it to 1200 calories especially if has been a "salad" day.

It seems like a lot, but really, it's not. Not at all. Your body needs food to have energy and burn fat. And if you're doing more intensive workouts, you need to increase your food intake a bit more (which is why activity level is important in general calculations for calorie intake) If you don't eat enough, your body enters what a lot of people call 'starvation mode' and the first thing it does is stores fat for future use; it basically thinks you're going to need it later on because food seems to be harder to find and may become more difficult with time.
If you eat enough that you're providing your body with energy, you're far more likely to lose weight.

It's like doing the limbo; you don't want too high or you'll hit the bar, but you don't want too low either, or you'll crash to the ground.

This ^^^^^

1200 calories may help you lose weight for a while but eventually your body will adjust and stop losing (and maybe gain a little, although a few pounds in either direction tends to be water).

In order to change your lifestyle to that of a fit person, you need to follow the plan above (in my opinion). It was scary for me to raise my calories as high as this said I should (I was a 1200 calorie girl for a long time), but I eat 1700 calories every day, run 4 days a week, do some strengthening exercises and while I have not lost anything on the scale since I changed to this approach, I have lost inches and become much better at running. So, take your measurements and take a leap of faith that the TDEE method will work for you (and you never have to diet again, just watch your calories according to TDEE).

You're gaining it back because you're loosing it by not eating enough; you starve and then you start eating because you're hungry, right? Everyone else is saying the same thing I am- you're not eating enough during weight loss. Loosing doesn't mean starving. It just means eating a little less than your body burns. Use your MFP goals to figure out the right calories for you by getting a correct TDEE. I suggest a weight loss goal of no more than a pound and a half a week. It's slower, but it will be sustainable.

Google Scooby's Calculator. It's another TDEE/ BMR calculator.

Also, look into lifting weights. Like serious heavy lifting. It won't make you bulky, but it will build muscle that will give you that lean, fit look once the fat is burned off and boost your metabolism. This is what I'm doing and I'm loosing a pound + a week while being able to eat 1800+ calories.

Have you had a check up with your doctor to rule out any thyroid issues? It also wouldn't hurt to speak to your doctor about your weight loss struggle. Every body is different, so it would be great to hear from your doc, what he or she thinks your calorie intake should be.

I was consuming about 1200-1400 calories when I was on my weight loss journey, and it worked. I ate great food, and was never left feeling starved or unsatisfied. I ate when I was hungry, and I ate well. Everyone's opinion on here is great, but I don't 100% agree with them telling you to eat more, because I didn't, and it worked for me. AND I was healthy. I went and still go to the doctors for a check up every 6 weeks and I am a healthy girl! Like I said, every person's body and health is different. You have to learn what's best for YOU

My best advice is to make a doctors appointment. They are there to help you! Also, amp up your workouts. After about 3 workouts, your body starts to get used to it's exercise schedule and that results in it not having to work as hard. Change up your workout routine about every 3-4 workouts.

Good luck! And don't lose hope, you can do this!!

By the way, I totally agree with Postrockandca. If you're going to start weightlifting, take in even more calories. Leave the 2lb and 5lb weights on the rack. Lift heavy and still have great form.

Like everyone else has said, you are not eating enough. If you were extremely short and didn't exercise at all, you might be able to get by on 1200 calories. But at your height, you need at least 1700 just to fuel your body if you did absolutely nothing besides sleep all day!

To maintain your weight, while doing Jillian DVDs regularly, you would need 2600-2700 calories per day. (And that's if you have a desk job all day.) So to lose weight, you can safely eat around 2000 calories or maybe even a little more than that. When you starve yourself, your body systems, including metabolism, slow WAY down to make up for the lack of energy. Try upping it to 1500 for a week then try 1800 for a few weeks and see if that helps. If you have been eating at 1200 (with exercise) for very long, then it will probably be a few weeks for your body to go back to normal, then you will find that the Jillian DVDs and a healthy diet will melt the fat right off of you!

Good luck!

my sister has lost over 2 stone by going to weight watchers so it works sometimes

2 stone? what the heck is that? (sorry for being daft!)

Track your sodium and your sugars. These are hidden weight holders. I gained on a deficit due to sugars. Also figure out what you eat that makes the scale go up and find a substitute for it. I know some people are going to yell BS but I have been on my journey for over a year and this is what worked for me. Also I agree with what everyone is saying about a few more calories. Try maybe 1400 and aim to hit that everyday. If you drink beverages other than water remember to count them. When I first started this I couldn't understand how I had ended up way over 200 lbs I thought I barely ate. Well days I barely ate I may have drank an extra 1000 to 1500 calories in juice. All that sugar and added stuff adds up fast. Next schedule with your DR and bring in your food log. They maybe able to help see where they can direct you better. Good luck!

Second that! I cut out sugars and the weight is coming off. My doctor told me (in a smug manner) 'calories in - calories out'. If that's true, I can eat only 2 cinnabons per day, work out an hour at the gym and be under my 1430 calorie limit. SuuuurRRRrre.... What works for me is to keep my 1430 cal/day, do intervals on the treadmill (30 minutes - walking at 3.3 for 5 min and running at 5.3 for 1 minute), weights 2 times/week, stay away from as much sugar / high fructose corn syrup as I can, stay away from the diet sodas, drink loads of water and savor the food I eat. I also cycle carbs - MWF are low carb days, TTS are high carb days and my free day is Sunday.

You have to eat to lose weight!!!! I eat every two hours......

I agree with everyone else. GOTTA GOTTA GOTTA eat more! Try adding some nuts and seeds to your diet. Or try almond, peanut or cashew butter with some rice cakes or (healthy) crackers. They're good fats with no cholesterol.
