I love this and I have really been delving into the attention or low self-esteem aspects of this. If someone wanted a life change, simply for themselves, I do not feel that they would find it necessary to yell it from the rooftops and shame others.
The flip-flopping of diets drives me crazy as well. If one day you are off sugar and the next day you are eating an Oreo, I am losing respect for you because you are not serious.
It is a fascinating topic, diets and lifestyle choices, but I do feel that many of them can sometimes be damaging, if you see food as the enemy or people who do not follow your path as ‘wrong.’
