One week of re-feeding - Belly fat again

Hello all,

I have completed one week of re-feeding. Mostly fruits and salads. One two days ago I did have pasta with cheese and did not feel right. I have put on 4lbs out of 6 that I had lost. My belly is fat again the it was before. I am hoping to be on fruits and salads for whole next week.

I have a question, why is my tummy growing instead of any other part of my body?

Thanks.
