From my experience and in my opinion it's not worth straying from the healthy diet.The suffering is too much & too painful!
I think it comes down to being careful,maybe indulge a little
if you really want ,but balance it out with something healthy.

Like a square or 2 of chocolate after a healthy salad is much easier on the body than just the chocolate alone.
Or a glass of wine with a healthy meal instead of a few drinks on an empty tummy or a tummy full of junkfood...

I know it can be a challenge to avoid/refuse all of these things
especially when family &friends are indulging all around you.

I am happy eating a raw carrot as they eat their sweets...I know my body will be better for it, function better, feel better and I won't feel ill later because of it.
It's just not worth it.

People call these foods "treats" I say they are "threats"
