There's NO way your body can maintain 186 on 1,400 calories with you burning god knows how many calories on the 30DS as well. Especially with you gaining muscle, which will in turn burn MORE calories.
Since you seem pretty averse to having a McDonalds-for-lunch, Kraft-mac-and-cheese-for-dinner day to coerce the numbers to move, (not a bad call, I'm just too impatient!

) then my best suggestion would be to put the scale away for a week or two (if you can!) and start measuring every few days instead... it's a fantastic indicator, and will probably make you feel great to see the inches coming off instead of seeing no change in the number.
Do NOT let it throw you off track. Look how far you've come.....! Just keep working at it, honey.

We're all here for ya.
