When I was growing up my father would always observe what people were eating and sometimes make comments. For instance, if someone overweight were walking down the street and eating an ice cream cone, my dad would comment to whomever was around him that the person did not need to be eating that. I assumed this was normal and that everyone does this.
Today my husband and I were at a buffet restaurant. I enjoyed a healthy dinner and refrained from eating more than was appropriate. I did however, desire some dessert. I asked my husband if he would go get one for me and he was surprised. I explained about the thing with my dad and how I always feel certain that people are looking at me and thinking, or perhaps saying, that I should not be eating that. He told me that it's my issue; to look around the restaurant and notice that there are people of all shapes and sizes present and that everyone is eating some dessert.
My husband is rather athletic and in really great shape. In no area of his life is he ever concerned about what people think. He is a Christian and does try to live in connection with God and in God's will; so he is definitely concerned about pleasing God, but could care less if people approve or disapprove of him. I think in this area, my husband is healthier than me.
I think it's my own issue if I care what people say or think.
