This excerpt from a book :
I want to know what does 'commit' mean?
"...The first step is gaining a better understanding of fat. Instead of conceiving of it as a single thing,we have to recognize it as several discrete types of a similar compound. Not every fat is your enemy .Fat are among your best friend. It is smart to commit to a balanced-fat diet , not to a no-fat diet.."
Could you please tell me the corresponding definition from the following dictionary?
Thanks so much.
