An interesting observation.
You do influence more by how you act and what you do, and perhaps how you feel, if that makes sense. If they see someone in good spirits, and healthy, that does more than any words.
As I started my carnivore right before the holidays last year, I'll have no problem staying on the path, with regards to the diet. I may indulge in to cuts of meat I normally don't consume on the regular, like lamb. Not even close to being worried about the sweets that will adorn the table that day. That may also be a reason why I may grab a bite of it. I am fortunate not ever to have struggled with weight, so it's unlikely I will trigger a plateau in my weight journey, in fact I could use 2 extra pounds.
