Your hungry, so eat already And speaking of eating are you getting enough protein and fats to feel satisfied when you eat? I am a lifetime member of WW. I know how carb heavy that diet is and it is also pretty darned low fat. Fat makes you feel like you have eaten something.

Is that TDEE based on Scooby's calculator, MFP's, or an activity tracker? How did you reach TDEE of 1777?

Why the 20%, do you have a massive amount of weight to lose? Ya, didn't think so. If you are within 25 lbs. of your goal weight it should be around 10% or whatever gives you .5 lbs loss per week.

Have you read all the EM2WL stickies about what to expect when you up your calories and the other good info there? This isn't an instant fix, you have to give it, your body, and your head time to adjust to eating more. There will be weight creep due to glycogen/water. It will seem crazy to eat so much. And you might feel hungry as your body adapts to the idea of being feed for all the cardio you are submitting it to.

TDEE 1777 / 1183 BMR = 1.5 activity factor.

You did not select the level for 5-6 hrs of exercise a week - you got between Lightly Active and Moderately Active - no wonder you are hungry.
And selecting 20% deficit with so little left to lose.

Should be selecting 10% at this point.

And be honest with hours of exercise weekly.

So no - you actually are not doing this right.

You are doing something else out of fear to keep a bigger deficit than reasonable.

And read the topics - you'll discover the advice all over to increase calories slowly. 100 extra daily for a week at a time.

Since doing a lot of cardio, your body has just been itching to store more carbs with attached water - so you should indeed see water weight gain. Same way as summer comes and you get warm more often your blood volume increases - natural body response to changes around you.

That will increase LBM, and metabolism, and weight.
And you were going to gain that weight as soon as you tried to eat at maintenance anyway, so who cares - it's spread throughout your body anyway.

Your eating goal even with 10% should be about 1850.
But you've been abusing your body at 1200 for awhile you said, so you should move on up slowly to 2050.

Sounds good! Keep up posted!

If you are under your TDEE, keep upping. After you get to the 1850, stay there for a bit then take a small caloric cut. Staying at 1850 gives your metabolism a chance to reset. Then when you take a caloric cut, it will work! Good job so far. I came from a 1200 calorie backgrounf also and it can be mentally challenging to up and stay at TDEE buy you are doing great!

That's awesome! I did bigger increases but my TDEE was way up there, so I didn't want it to take forever. To get from 1200 to 2800 at 100 per week.... I would have been increasing for 16 weeks! Then once I got to maintenance, to stay there for awhile... was just too long for me. So I increased from 1200-3000 over the course of 3-4 weeks, if I remember right. Then once I was to 3000, I started gaining so I went back down to 2800. I've spent the last three months at maintenance calories. I haven't lost weight, which is to be expected but I did lose inches and also have a much healthier relationship with food and the scale! Also, even Scooby underestimated my calories burned. My numbers were closer to the mens numbers than the womens. So the only way to truly "test" your actual TDEE is to keep increasing until you start gaining. If you aren't ready for that though, at least try to get up to the calculator recommendations. In the future if you feel stalled out, you can revisit your TDEE and try to push your limits.
Just stick with it lady!
Just remember to stay at maintenance for awhile before starting your cut. You have to give your body a chance to heal, or it will just think your new cut value is maintenance and you won't lose. You have to go up to maintenance, hang there, then take a reasonable cut. That's the idea for EM2WL anyway! I see a lot of people just try to go to cut value as soon as possible. They often have initial results but then plateau again and were in the same boat they started in.

That was also a challenge for too me bc my cals increased more than the double. I added calorie rich protein shakes with nut butters! Good luck!
