looking to lose the last few kg

Options
Hi everyone! I'm looking to lose the last few kilo's (aussie here!) and be a bit less flabby. I lost a lot of weight a few years ago, and managed to keep most of it off, until i went back to study and put on a few kg. Luckily not too much but i was eating very terribly while trying to write my thesis! I've lost almost 30kg (or 59 pounds as MFP tells me) and am hoping to lose a few more and feel a bit better about myself. I love to bake which is a bit of a problem, but try not to do too much of it!
I forgot to add, I have IBS which limits a lot of what I can eat including mostly high fiber things like vegetables mostly, but also limits other things too.
