New low weight today

I have recorded a new low weight today - 324.2 pounds that gives me a weight lose of 85.8 pounds. So what is going on almost no lose for several months and now 6 pounds in the last 5 weeks. Well there are two things I have changed. I have reduced my calories by 500 now this was doing by eating one less meal but I also have added a snack and when needed two snack. So sometimes I am eating some of those 500 calories but not everyday. Also two weeks ago I started running and it has been very hard. I am cycling a little less because of the running wears me out so much but I believe the running is giving me a boost and I like losing again.
