Want to scale down the Plateau!!!

kmfl1

After plateauing for a month and a half, my wife....who is an MFP vet....thought I was in "starvation mode".
I had lost 38 pounds and we thought I needed a kick start after 6 weeks of nothing.
We increased my calorie intake and now I'M GAINING!!!!
What's going on here?
I exercise 6-7 days a week for over 45 minutes a clip!
I am 99% of the time well under my calorie goal?
HELP!!!!!!!!!!!
