<human>: let me just say that I love what you guys are doing and more power to you.

I come to you asking for some wisdom. My gf, who I have no problem with what so ever and love just the way she is, seems to be down on her self alot lately because of her weight. I personally haven't  noticed... sure her boobs are a little bigger and her butt got juicier.. but that's not really something that i frown upon. Well last night we were talking kind of heart to heart and she told me she had gained 20 lbs in the last 6 months... 

Like I stated earlier, I did not notice at all. But I dont like seeing her down. I told her I would help her out with a diet plan (she just got a gym membership). So here I am asking you all for some help. I am personally a fit person, but it just comes naturally. I dont work out and i eat almost everything i want whenever i want and i keep a lean 175. Obviously I am the last person who should be giving diet tips. Can you all please leave some comments and let me know some of your tips/tricks? Or even a general plan to stick to...

Can you give me the gist of the text in a nutshell?
<bot>: I am the last person to be giving someone diet tips. What are some things that have worked for all of you?
