Serious Ques That Sounds "Unbelievable"...

Have you been tested for insulin resistance or metabolic syndrome? Your description of your problem fits. You should eat a balance of carbs and proteins. No more than two carb servings per meal or snack (30 grams) and two protein servings (14 grams) plus any non-starchy veggie. You can eat more protein than carbs but not more carbs than protein. You should eat every 2-3 hours to keep your insulin levels level. Excess carbs are stored as glycogen for about two hours and then either used or stored as fat. The body finds it easier to use protein from muscle for energy than stored fat so eating more protein will result in stored fat being used. There is an excellent book, The Insulin-Resistant Diet by Cheryle R Hart and Mary Kay Grossman (an MD and RD respectively), that explains it much better. If you haven't been tested then you should ask your PC next visit. It's difficult enough to lose but barriers put up by our bodies can almost defeat a person. Having the knowledge and tools to be successful is mandatory. Good luck in your journey!

less carbs!
more protein and vegetables.

Not necessarily true, depends on what kind of carbs she's eating. Simple carbs do need to be reduced or even eliminated. The body and especially the brain needs some complex carbs. Carbs just can't be eaten on their own.

In the past, I have had some of the same issues. What I do now is;
I weigh or measure everything (everything).
I log everything (everything) that goes in my mouth.
When eating out, never guess how many calories. If you can't find out and work it into your plan, don't eat it.
A few "little" errors in judgment when estimating how much of a certain food you eat, can sabotage the whole program.
I don't use the calories burned in the database.
If I had to bet my life, I would bet they are overestimated. If you use those numbers, eat about half of them back.

Since I started going by these rules, I don't have anymore mysteries, like gee, why did I gain weight this week instead of lose weight?

Edit: Oh, and revisit your MFP setup. Make sure you are choosing the right lifestyle setting, etc.

And most of all.. be honest with yourself.

I should only have taken 2 weeks to "readjust" to the new consumption, right?

*sigh*

I don't think that's true. I think it can take quite a few more weeks... if you check out the group "Eat More to Weight Less" (click the "groups" heading up above) and read about the metabolic reset, it's suggested you do it for 8 full weeks before resuming a cut.

Just check out the group and read the stickies. It may not be for you, but it may be just what you need. Some weight gain is to be expected during the process though.

THIS!!! ^^^^
It will take more than 2 weeks, especially since you have been eating so low for so long. You will likely see an initial gain, then maintenance, then start losing again. Check out the group as the previous poster mentioned. In that group they advise giving it a full 6 weeks before you change the plan or give up. It really can make a huge difference. Hang in there!

this...i believe the same. you need to reset your metabolism and this takes longer than 2 weeks! also you might try cycling your calories....

I agree with what most of the posters said previously. What I have to add is asking what you have your daily activity level set at? Sedentary? If you don't have it set at sedentary and you are logging and eating back exercise calories, that would be a problem. Anything above sedentary already accounts for exercise so you'd be eating your exercise calories twice.

Have you calculated your BMR ? I was not eating enough calories either. Once you know your bmr, you can adjust your caloric intake bases on your level of activity. Hope that helps. It really made a difference for me. Also, do go just by the scale. What are the non scale victories?

i am under a docs supervision... n have been on 600 -1200 cal at different points along my journey. there has been stalls n plateaus n i can say now nearing my goal weight ...it has slowed..has its spells but in keeping honest on portions n what i eat n exercising...the weight continues to come off... n not just a pound a week...its usually more. knowing your body n how food affects it works for me. in the last 4 days i have lost almost 4 pounds... n heck i even had a small cinnamon roll lol... my logs say a little over a 1000 cals a day but honestly with the big spoon of peanut butter lol or an extra piece of cheeze etc i know it is 1200 cal easy. i walk approx 10K a day, lift some weights, drink my water and never am tired n full of energy. i use to stress out alot on what this n that etc etc...but i found it more valuable to watch everything that i ate , watched my weight daily...watched how much exercise and watched the results learned from it. what i do may be different from someone else...but...its working for me.

hope you can find what works for you.

YES.
