Congratulations on your weight loss so far! That's terrific.
It's not unusual for weight loss to slow down especially as you get close to goal weight. You didn't mention how far you are from that. Let me know and I can see if there's anything else to suggest.
In the meantime, the majority of people lose the majority of their weight within the first six months -- so you still have a while to go. A lot of people had setbacks during the holidays where they either gained slightly, or stayed the same -- even though they thought they should have lost! You may be coming off a similar situation.
I would suggest increasing the intensity of your exercise; not necessarily the amount of time. Sometimes, that helps to jumpstart weight loss again.
In addition, be very vigilant about your portion sizes for a while; maybe even weigh and measure for a week. You may have gotten a little lax after being on the Program for a while. That often happens.
Let me know if any of this is relative for you, and how far you are from goal.
I hope this helps.
