<human>: Condense the text into a few key points

I've so far lost ~6kg/12lbs, which puts me halfway towards my goal; currently I'm 70.5kg (~155lbs) at just over 5'10".  I'll be honest, I've plateau'd pretty hard, I've not been very good over the past few months.  But at the same time, I weigh the least I have in the past 5 years and that's not insignificant to me.  I guess I should note this was through diet alone, no exercise. I thought I was doing pretty well, then I saw this halloween pic: 

I look ok from the tits up, I even have a collarbone...  but tits down it suddenly turns into the nutty professor fat suit.  It seriously looks like I'm 4 months pregnant - and I've been told that if I have a cigarette on the street (especially after a large meal) people give me dirty looks because they think I'm actually pregnant!  

Feeling pretty down about this (and other things, but that's irrelevant) right now.  In addition to eating right to continue with the weight loss, what can I do?  Do I just put on weight in my middle and I need to accept this?  Do I need to do some sort of specific core exercises and this is just the result of a lack of tone?  Would targetting this area with exercise realistically even help?
<bot>: look really pregnant and it makes me feel like shit, but I'm actually only 10lbs from goal weight.  Can I do anything?
