That does sound a bit high. Most likely it is water weight. TM

It's not necessarily healthy to lose any more than 2 or 3 pounds a week. In fact, some health experts will argue 1 pound a week is ideal. It doesn't even sound like you did that much, I mean you walked an hour and here and there on the other days but thats not a whole lot of exercise. If you changed anything in your diet or if you are on any medications or drugs, check into that as well.

Your weight can flucuate that much in just one day! Think about how much you take in and what you put out. All that has weight. If you weigh with a full stomach and full colon you could very well weigh 6 pounds less after you wake up the next morning with an empty stomch and take take a poop and pee. That's why a doctor will tell you to weigh at the same time every day if you are watching your weight.

Weight tends to fluctuate a lot. I have dropped 5 pounds in a day before. It was mostly water weight. If you were very inactive before, just getting some exercise will change your weight. If you are trying to lose weight, you are on the right track. Eat right and exercise. Just remember weight drops off faster at the beginning when you are trying to lose weight.

It should be.

I run triathlons and it is typical for me to fluctuate up to 8 pounds over 12hours.

Likeley you just ate when you weighed youself the first time and need to eat the second time. I wouldn;t worry unless the trend continues and you eat normally.

Ever see thinner??

normal, sometimes our weight fluctuates, esp. if you are doing some exercise

if you have increased your activity level, and are eating healthier then that is normal
