Whats the best solution to shifting the last 14lbs I have to get rid of?

Looks like you've been pretty successful with what you are doing. Why would you want to change it now?

because I have plateaued for about a month now.

I don't know what you're doing now, but have you tried adding in some strength or resistance training? Adding that to my exercise program helped me break my last plateau and sped up my weight loss since then.

I increase my calorie intake for one day, that seems to boost my metabolism.

Exercising more has really helped me!

I gave up wine for a month and that spurred my weight loss after being on a plateau for the majority of the summer.
