I used to be skinny and a lot of people in school would always have to remind me of it
I could eat and eat and eat and the only weight I gained was from the food  In fact, my dad used to call me Jethro (the character from the old tv show The Beverly Hillbillies because he had a huge appetite).
For a long time I thought I would never get past 125 lbs.

Well, after I turned 30 that all changed
I am not obese and I don't consider myself fat but I have gained weight
I blame it on getting older and not being as active as I once was.  I still take walks and take the stairs instead of an elevator but I know I could do more but exercise is not as appealing as it used to be
And, I should drink more water and less other drinks but I don't have a dislike for water but it is recommended a person should drink so much water a day (I knew how much but I forget now).
