How much does your weight flucuate?

Mine fluctuates up to 5# throughout the course of the day. It's the food, beverage and waste that's in your body, plus any changes in water weight caused by sodium, muscle inflammation, hormonal changes, etc. Or lack of water weight from excessive sweating... I've dropped as much as 2# after a long run.

My weight fluctuates a lot as well (2-3 pounds increase or decrease) but I don't think too much on it. So long as I see it steadily going down (which it has been since I've started). Starting a diet is a new thing to both your mind and body so it sometimes takes some getting used to. Your body also goes through many stages of change that might be causing the fluctuations. Bloating, excess water, clothes, etc will give you a different outcome each time. Also keep in mind that if you exercise a lot, not only is your body burning calories, it's gaining some muscle as well and muscle has mass that will show on the scale. Do your best to weigh yourself in the same situation as the night before. For me, I weigh myself in the morning after I go to the bathroom and make sure I have nothing on, not even socks! (Yes, I'm that paranoid that socks with cause my scale to show a higher weight. XD) I also hop on the scale 2-3 times just to be sure.

The only reason you need a scale is to know that you are losing. One scale can say 150 while another says 140, but so long as the numbers are going down, who really cares how much you ACTUALLY weigh. It's what you see in the mirror that determines if you are happy with where you are at or not.

Also, don't be afraid to weight yourself EVERY morning. Studies have shown that people who weight themselves every day and know their weight are more likely to be more determined to lose weight. I know that when I see the numbers in the morning, they stay in the back of my mind throughout the day and I'm more careful about what I eat.

I hope this helped. Don't worry, you aren't alone. We're all here doing the same thing here and we're all here to support.

Stats, and Gender would play a big role.

3 to 4.5 pounds every day. I believe your true weight is the one in the morning.

Every morning you wake up after fasting, your body wakes up beeling in a catabolic state. a little dehydrated maybe, and definately hungry. Everything has been digested, the body is retaining the least water, and your height has also stretched maybe about 1/4 of an inch.

On average your waist line can be about 1/2" to 1" slimmer at this point. and before you jump up on that scale in the morning also make sure you took care of your morning "laboratory duties". This will ensure that you are at your "Dry Weight" this is the consistant one I follow and the only one that ever makes sense.

Personally I jump on my digital scale 3 times just to ensure accuracy, and I'll take the 2 consistant readings as my official weight. My scale however has been pretty damn accurate that 90% time the readings show consistant for same weigh-in session.
