4lbs in 2 Days!?

Try weighing yourself later on in the day. Weight is known to fluctuate, also when weighing always wear similar clothes you weighed yourself previously.

It's normal for your weight to fluctuate by a few pounds based on a lot of things--retaining water due to sodium intake, retaining water to help your muscles recover from a workout, where you are in your cycle, etc. Unless you ate an extra 14,000 calories this week, it's not fat! You gain a pound of fat by eating an extra 3500 calories.

I'm right there with you in terms of being close to 200. I'm finally losing weight again after hitting a plateau for a few months (I realized the problem was inaccurate portion sizes and got a food scale). I was at 199 before the holidays, then gained a few pounds, and am now down to 203. Stick with it! You'll be there in the next week or two I bet!

Your body weight fluctuates naturally and can do so by quite a bit. I have seen my waver by a few pounds over the course of a week without making any changes to my diet/exercise routine.

One thing to consider is water. Hydration levels can really affect your weight. You will actually gain a pound or two over the course of the day as you drink water. This is ok. This is good, actually. You need to stay hydrated, so don't worry about a few pounds.

Also, menstrual cycles can affect weight. You start to retain more water. I have seen my weight fluctuate by as much as 6 pounds the week I have my period.

In the grand scheme of things, a four pound fluctuation isn't a huge deal. Just stick with a healthy diet (including lots of water) and exercise and know that it's normal.

You have not put on 4lbs of fat in 2 days so its most likely water retention. Have you been drinking the same amount of water? Also your weight fluctuates. You will likely lose it all next week. Dont be discouraged.

Only weigh yourself naked - right after you get up & pee - once a month two days after your period ends.

No seriously, Same time, same clothes, same day each month.

Don't weigh yourself after you exercise. Muscles retain water to heal themselves so you will actually "gain" a couple of pounds.
Don't weigh yourself after eating.... I just love what a couple of pounds of food will do to the scale....
Don't weigh yourself during your TOM..... You know you will be at least 5 pounds heavier.

The human body has been known to fluxuate as much as 5 pounds in one day. Hide the scale and concentrate on the NSV- non scale victories... Inches you've lost around the waist, The clothes that fit better, Being able to jog for 1 minute instead of 15 seconds. That is so much more important than some number on the scale any day.

weigh naked first thing in the morning... you probably have some water weight going on there... I see our diary is not viewable...but keep an eye on your sodium intake, perhaps?

it's water or poop. don't freak out.

Also, how is your blood pressure? Make sure that you aren't seeing any signs of hypertension. Water weight does fluctuate and is normal (especially among pre-menopausal women) and for many other reasons. Sodium levels. Potassium. Etc. Just make sure that water-weight gain is the problem and not a symptom of something else. If this only happens once or occasionally. I wouldn't worry about it, but if you see additional gains like this, check it out.

Log everything in an app which smoothes the data (separates out the fluctuations from the main trend). There are a few out there, but I use Libra for Android...

High sodium intake and high carb intake can wreak havoc on a weigh-in as well. I can be up 2-3 pounds easy after pizza night!
