I am having a similar problem. I am 9 months out and have lost 115lbs, but have gaind 5lbs in the last week and a half so am to a weight loss of 110lbs. I have started working out a lot harder and am hoping that it is all muscle gain, but I hate seeing the scale move this way. I still have about 30lbs to lose and need help! I don't think I am over eating, but I know that I do eat a little fast. I am also not getting full at the same point I used to, but don't think I am over eating. I am still stopping after eating a small portion of food, but because I want to not because my tummy hurts. Thoughts? I think I am going to watch my carbs more closely. HELP ME! I am really sad and starting to worry. I have come too far to go back now.

Are you tracking your food? I was going up and down with the same few lbs for a bit (just over 9 months post also) so I started tracking again and making sure I got all my protein and water and I'm down a few lbs now!!

I am 9 months out and need 5 pounds to reach my goal, I am so exited about that, but I started training for a marathon a few months ago and noticed that every time I would train or exercise I would gain muscle therefore weight and I hated to see my scale move the wrong way, so I decided to reach my goal and then start exercising as part of my maintenance. I do go to Zumba class twice a week but I already know those days the scale will not move.

Zumba is a great workout. I've heard that when you start building muscle, your body tends to hold onto extra water weight, but that it is eventually shed. Don't be afraid to build muscle since it aids in burning fat. In the end that muscle will help bring the numbers on the scale down and you'll look and feel better. It looks like you are doing awesome!
