Good for you.
There are no real tricks just keep eating more of the foods you enjoy.

Always loved letting go and stuffing my face. LOLOL

I know right?
I really thought I could do 10 but the buns stopped me.

4 is the most I have ever had in one sitting.

You might consider padding each other to look fatter.
There are a few threads here on that subject.

Honesty, personality, sense of humor.

I was really thin growing up.
Thin all thru school and college and first marriage.
Gained weight then lost it,gained again and lost it.
Finally decided I would rather be chubby than skinny.
Of course enjoying being chubby led to getting heavier and heavier.

The highest weight for me was 425 and never really had sleeping issues.
My BF said I snored a little but not all the time.
Rolling over in the bed was pretty hard tho'.

Not me realizing I'm fat but other people letting me know LOLOL
Last evening was a girls night out with some friends and a few I haven't seen in many years.
We all meet up at BJ's brewhouse for dinner and I will say none of us are as skinny as we were in high school.
One made the comment OMG we have all gotten so damn fat over the years haven't we?
You know women always complaining that they are fat when they really aren't.
A couple were slightly chubby I will say that.
Everybody commented on my outfit and how nice I looked but were amazed how fat I was after being so skinny growing up.
I loved being the fattest in the group LOLOL I felt so special !!

Your link didn't work for me so I couldn't view it but I have seen Dr Phil discuss it in a few videos that is why I mentioned it.
My first marriage was horrible because 3 of his family members were narcissists.
His Mom and his two brothers.
They would always try to drag you into their game then blame you for all their problems.
One night the mother got arrested and thrown in jail for driving under the influence and somehow I was the cause even tho' I was 2 states away.
They were just horrible people.My husband wasn't at all like them but we had our own issues to deal with like drugs,alcohol and infidelity.
