4 LB Weight gain in 1 day after 6 miles on my Treadmill yesterday?

I worked out really hard yesterday so I could take the weekend off. I thought because I did 6 miles that I better up my cal intake a bit so my body doesn't think it's starving. I know I didn't consume more then 1500 yesterday and per my treadmill I burned about 800 of that. I did 2 miles in the morning and another 4 miles in the afternoon. So why am I up 4 lbs this morning. I was 177 yesterday and 181.5 this morning. I didn't plan to work out today but I did another 2 miles before work this morning because I'm upset. I had alot of salt yesterday and drank alot of water. Is it possible my body is retaining 4 lbs of water just from yesterday? I just joined peer trainer last week. I weighed in Monday and this Monday will be my second Offical weigh in. Is this just going to be one of those weeks I don't loose anything, even though I have been working my but off. I was at 181 last Monday and after my work out this morning I was at 180.5. What's up?

I'll post a short comment from book The T-Factor Diet by Martin Katahn, page 211:
"An increase in exercise time or intensity can lead to a **brief** [asterisks mine] gain of a few pounds... If at any time you... suddenly increase your exercise time or intensity a significant amount... you may gain a couple of pounds overnight. This will be gone in a matter of 1-2 days. It occurs because a sudden increase in exercise... will cause your exercised muscles to take in an extra load of glycogen from subsequent meals. Since glycogen is stored with 3-4 parts water, it means a considerable weight gain..."
I hope that helps. I try to remember that anytime I exercise my muscles in an unaccustomed way, the scale will show a temporary weight gain the next day. Try not to be discouraged. Your calorie math is correct and will show results over the next week or two.

Always remember that the numbers on the scale are there for feedback - they're best viewed as a trend, not as an absolute, because a lot of things can affect that number besides your actual change in body composition.

I was the same as you when I started exercising for the first time. I walked 2 miles a day and by the end of the week I was up 5 pounds. Once my body got use to me walking everyday the pounds starting coming off. Don't give up you are doing all the right things. Keep up the good work.

always remember that calorie counters on fitness equipment are unreliable at best. And with treadmills, just make sure you're never holding the bars...

Once upon a time...I think it was my 4th diet, back in 1993, I was attending a Weight Watchers meeting. When the leader weighed me in, she clucked with displeasure at my 2-lb gain (I was the most consistent loser in the group, probably because I was the youngest, at 23). I said I wasn't surprised because I'd added a weight routine to my workouts, and she laughed at me, saying nothing I did could have caused a 2-lb gain in muscle. I said I knew it wasn't muscle, but everything felt a bit swollen and I had done this before blah blah blah. I wanted to smack her. The next week I dropped those 2 lbs plus 2 more. So without knowing the glycogen-water specifics, I was familiar with the phenomenon. I know if I'm sore in the morning, the scale will probably show a little gain for a day or's about the only time I don't freak out about a gain!

Thanks for the info. on the glycogen weight gain. I too have been in that same boat and really gave up dieting temporarily in disgust with myself. You may have just kept more than a few PT members from giving up! Thanks again.

To the OP, also remember (and this doesn't apply to an overnight weight gain of course) that muscle weighs more than fat and when you start building muscle you may gain weight in the short run but that increase in muscle mass will go to work for you in the long run and help burn up calories more efficiently.

Keep up the great work!

And one more note..

I think they are right about this little weight gain, but also remember factors like that time of the month can also play into weight gain. Try not to get discouraged by day to day weight totals and keep track of things on a more long term basis.
