don't know what I'm doing wrong :-(

You have been at it a week.
It takes 2-4 weeks to adjust then you should start really kicking it in.
first and foremost...you dont eat enough to lose anything.

You will survive this with patience!
Eat between 1600-1800 calories daily if you are 5'2" and above and work out 3 times a week.
Sleep 6-9 hours a night.
custom set MFP for Protein and Fat to 30% and always get your macros in.

If you need additional help feel free to PM me.

Your not eating enough calories one day, skipping meals, then go over your calories the next. Did you not eat at all today?

My advice to you and to everyone else.......you did not gain your weight overnight and you are not going to lose it overnight! Also, stop thinking of losing weight as a diet, it is a lifestyle change. My key to losing my 16 pounds so for is simply watching portion control, and making sure I'm getting enough calories throughout the day. If I exercise and burn calorie I make sure that a replace them back, and I don't eat no less that 1200 calories per day. My calorie range is between 1200-1500 calories per day. Finally, drink plenty of plain water.

THIS
He knows his stuff.......

I'm skeptical... I was Very slowly loosing weight/plateau eating 1200/day but burning about 400. Then I read all the posts about not eating enough so I bumped it up to 1200/day net and I gained back everything I had lost in the space of two weeks. At which point I gave up in disgust and am now going to go back to net 600. I'm absolutely sure your formula works for you (and by you I mean all of the wonderful people who have shared what worked for them) but I think different people may have very different basal calorie needs

could just be gaining muscle mass...people tend to see their weight go up a little after starting an exercise routine. nothing wrong with gaining some muscle you could be losing inches and not even know it if your not logging it.

I see that you have skipped lunch occasionally. Some days you are better than others with getting your fruits and vegetables in. Try and eat less processed foods. Don't be discouraged by no weight loss this week. Some weeks I have stayed the same. You will have good and bad weeks. I have always gain a few pounds around a certain time of the month. Keep plugging away. This website is great for talking to others going through the same thing!!

I have to watch the amount of sodium i take in. All it takes is that evil handful of potato chips when I get home from work for my body to hold extra pound or two water.

Water weight will happen when adding any amount of food over the norm.
Also since you eat at 1200 or below you have lost some muscle mass.
By adding extra food and carbs the muscles will flood with water for nutrients.
You dont give enough nutrients though so at some point the body will catabolize the muscle tissue and you will gain fat!

Wait till you finally PM me for numbers and I tell you to eat 1600-2k a day.
Then after a week youll have energy like none other!

Then the fat will come off but the muscles, including your heart, will remain intact.

A few things may be going on:

1) It is my understanding that when you are working out a lot and building muscle- you will retain water a little more. I guess that to build muscle, you actually tear it and it recovers bigger and stronger- but off the bat your body holds on to more water as an aid to this repair. Your actual loss may be "hiding" behind water gain.
2) If you are working out too hard/long without properly fueling yourself, your body will burn too much muscle and not enough fat. Then your body does not burn as much while resting, because you have less muscle.
3) If you are seriously upping your workouts, your body may be confused and will hang out at the same weight for a few weeks. When your body learns this is the new "normal" and that you are eating enough, it will suddenly let go and you will have a big loss. At least, this is what happens for me.
4) Your body comp may be changing and you might be getting smaller, but not losing because you are changing fat to muscle.

If it's any of the above 4- stick with it and in a few weeks you should see a good drop.

I would also suggest eating less sodium and less processed foods- and more lean protein. And really trying to stick to your daily calories every day. It's one thing if you are not working out- but if you are exercising hard, then your body needs enough quality food to fuel you through the workouts.

Of course-it might not be one of the above. There is always human error- counting too much for a workout, not measuring food, etc. Hoping things improve next weigh in.
