Medifast change

oviedom81

So I have been on Medifast for 6 weeks and I have only lost 8 pounds. I went to the center today and gained a pound this week. I have been staying on plan so I just don't get it. The worst part is when they did the body compostion the first week I joined Medifast my body fat was high. Six weeks later my body fat is more. How is that possible if I lost 8 pounds in six weeks and lost 9.5 inches overall. I started my 10 week training for my 10K on Tuesday with this being said each week my miles will increase. The center told me that next week when I come in they will change my plan. I am currently in the 5 in 1 plan. I just feel discouraged please help. I love Medifast it has worked so far but I don't know why my weight is going down as others. Thanks.
