How long does it take to break through a plateau?

I was at 250 for about 6 months; finally the scale shows 248.5 ..... but, this is taking too long! How long before I overcome this plateau and get this weight down? Need encouragement please :)

are you eating enough? Getting enough exercise? To break through a plateau you first need to try to figure out what is causing it. 

Plateau's happen, but six months isn't a plateau.....your body isn't happy with what you're doing. It's not working, time to reevaluate like Kathyn said!

My guess is that you are not eating the correct calorie intake for your requirements.

Eat too little and the weight loss quickly stalls out and stops because your body will not lose weight if it thinks you are starving it. If you are eating at the lowest calorie intake possible (1200-1400?) then you are definitely not eating enough. Eat more .. in the 1600 - 1800 range and your body will respond with weight loss. It happened that way for me; I stopped losing weight when I got a more active job.. doesn't make sense does it? More activity should result in weight loss but my body was telling me that I needed more calories and when I ate about 200 or so more calories I fell off my plateau and started to lose again.

Eat too much, (not measuring portions* or still having drinks with calories and not counting those) not counting calories accurately or even overestimating the calories that you burn through exercise and general activity ... all those situations can contribute to zero weight loss.

Weight loss is a fine balance and those numbers constantly change as you lose weight and also if you increase exercise/activity. 

*a recent poster said she could not understand why she was not losing ..was eating healthy and working out... seems she had stopped weighing the chicken breasts she ate for dinner most nights.. then she actually weighed one.. she had thought they were about 4 oz but it turned out they were nearer to 10 oz.. big difference in calories and showed where she had been going wrong. If in doubt weigh and measure!

Recalculate your numbers using your current stats and check your intake.

You asked us a question, but you didn't fill us in with enough info.
Like... How many calories you eat per day, and how often do you workout?
Those will help the poster reply out, and I'm not sure what's wrong with you at all, because I'm no MD, but what's going on with you isn't a plateau.

If I was to guess here. I would say you aren't eating enough, and your body is in starvation mode, but then again I really can't say that -because I don't have enough info to go on to help.

I'm not a person who likes to over step my bounds, but what I would suggest is make a doctor appointment, and get your thyroid check. If you are eating right, exercising 3 to 4 days a week for more than 30 minutes, and counting your calories.

I know your body is at a stand still, but something has to be causing that stand still. My body has been at a stand still, and I've been holding on to 188 for a while, and I broke it this week. I went from 1200 calories to 1600 calories.

I eat more raw foods, and I have a cheat day on the weekends twice a month.
I juice my own juice, and I drink lots of water, and take fish oil.

I've had an low active thyroid in the past, and that came with 250+ pounds, and getting my thyroid checked helped me a lot. I would not suggest it if I haven't been through this myself. I was put on a very healthy diet, and meds. to get it to function properly, but it's all about what we bring into our bodies in order for our bodies to shed the weight.
