Seriously, what the heck?!?!

Well it actually may be water weight, don't freak out yet! You're only in week 2, and when you start a new exercise regime your muscles have a tendency to retain water for repair.

It sounds like you're doing really great, don't give up, it needs more time. You should also take your measurements TODAY and go by that as well as weight, measurements are an accurate portrayal of the physical effects of weight loss.

Keep it up, good luck

I'm no expert, but I'm confused. If you are eating your BMR plus you are eating your calories burned through exercise, why do you expect loss? You have to have a net loss in there somewhere. Also, unless you know your own actual BMR, remember that it's only an estimate. And sites often give GROSS calories burned during exercise rather than net. Try not eating back your exercise calories - at least not all of them.

Also - make sure that you are taking in enough water. When you do that consistently, you will be less likely to retain water

Also - PLEASE REMEMBER that women of child-bearing age have monthly weight fluctuations caused by water weight as a result of hormonal changes. Once you've been dieting for a few months, you will clearly see your pattern and be able to remember to NOT weight yourself during the predictable weight-gain times.

It's not muscle this fast and while eating at a deficit. But it has only been two weeks. Often you will see a good loss the first week, and then not the next - could be water weight, could be your body adjusting to new eating habits and calorie intake. Give it time. And yes, measurements are a great idea - often the scale will show no loss, but the tape measure will.

Just keep at it and don't let the scale get ya down.

BMR is the minimum your body needs to live off. TDEE is what you actually use in a day. OP is right to be eating BMR + exercise cals as this still gives a deficit from TDEE.

Don't get discouraged measure yourself you might be changing your body shape.

^This.

If you are using the Wii check you have it on a level surface and check that the batteries are okay in the board. Mine were going the other day and it told me I'd gained 3lb (in one day?) I replaced them and my weight went back to what it had been the day before.

Even if it's correct, you've still lost 0.7lb overall (she says trying to think positive) just give it time. What I found was that my weight seemed to go up and down during the period of about 2 weeks, but after about a month I would see a definite drop on the progress chart.

I agree with the others - water weight, not muscle. You can easily gain that much in water just with your muscles repairing themselves. Plus, if you had any high sodium days in there, that could do it too. It happens to me ALL THE TIME; I'm very prone to water gains. So try not to worry, just keep at it!

MEASUREMENTS!!! can you check by a certain piece of clothing that used to fit tighter??

Perhaps you are gaining MUSCLE. Give it time. If you're eating healthy and moving your body...the scale WILL reflect those efforts.

Are your clothes getting looser? That's one way to tell if you're getting healthier!

NO to the first sentence. You cannot GAIN 1.3lbs of muscle in a week,seriously. No.

Second sentence,yes. Take measurements....your weight will fluctuate, inches are often a better indicator.

^ this.

it's water weight. 1 gallon of water weighs about 8 lbs. there are several reasons that the OP may be holding onto water.

obsessing about the number on the scale is the single worst thing that "dieters" do to derail their progress. forget the scale. weigh in once a month. stick to the program. the scale is a long term trend tool, that's all.

One meal high in salt/sodium can cause a 2-3lb water retention. You are doing everything right, be patient, stick at it, the scales will eventually reflect your effort!

you shouldn't worry so much about the scale and #'s. What's important is that your continuing your plan and keep up the good work. Check in next week and it could be quiet possible that you'll lose double the weight. Water weight is always possible but consider the way your clothes feel rather than what that scale tells you. Hang in there your doing great

Keep up the good work... weighing yourself every week can get discouraging because it will go up/down as your body adjust to workingout. Muscle DO NOT weigh more than FAT. A pound of muscle is exactly what it is... 1 pound just as a pound of fat is 1 pound. You wouldn't have picked up 1.3lbs of muscle in two weeks... so its more than likely water. Give it time.. check the way your cloths fit and stay off of the scale. I weigh in 1 a month... don't need to added stress of the scale. As for eating back my calories.. I usually only eat back 1/4 - 1/2 depending on when I workout and how much I burned.

Muscle does not weigh more than fat, any more than a pound of concrete weighs more than a pound of feathers. A pound is a pound is a pound. Where the misunderstanding often comes in is that muscle is much more dense than fat, so that, by volume, it seems to weigh more. That is, a pound of muscle occupies less space than a pound of fat. In addition, because a pound of muscle burns more fat than a pound of fat, even at rest, by increasing your lean muscle tissue mass, you're helping your body burn more calories.

But back to your question. If you only have a small amount of weight to lose, then you may feel like the weight training is not helping you move down on the scale. In fact, the number may even go up, but you will look thinner. This is due to an increase in lean body mass (muscle, bone, blood volume) and a decrease in body fat. In other words, even if the scale doesn't change much, you will probably see a difference in how your clothes fit.

1.3lbs of muscle on a week? Perhaps water or not weighing in under the same conditions as before (time of the day, day of the week, pre/post ablution).
