really struggling to lose the last 14 pounds, any tips.

If you're doing the 1,200 calorie thing, it is too aggressive for 15 Lbs to lose. With only 15ish Lbs to lose, you should be shooting for about 1/2 Lb per week and no more than 1 Lb per week. When you get within 10 Lbs, it should definitely be at 1/2 Lb per week.

You simply don't have the fat stores to maintain that large of a deficit and your body is responding by not cooperating. Your body is smart...it wants to hold onto fat, just in case it needs it down the road. When you go too aggressive with not much to lose, your body just responds by slowing the metabolism down. It'll be very gradual, but your body will ultimately respond better to a much smaller deficit at this point. I'm in the same boat.

as you have less to lose it comes off a lot less quickly. Try eating at maintenance for a week or two then go back to your deficit level of calories. Your body probably needs a break from dieting.

you really should be using a TDEE calculator NOT the calorie recommendation given by MFP.

thank-you for so much advice. I must admit I've been on a diet for so long, I was starting to give up. But reading everyone's posts, its made me more determined now to lose it, thank-you. I will try and vary my exercise i did get into a routine, obviously my body has got used to it.

How long have you been at a deficit? Maybe it's time for a diet break before the last 14?
