Answer: Well I can't say that this answer will be true to you, but here's my answer
I almost always put thought into what's going into my body. I worry quite often about how foods fat will affect me. I did it mostly because I was worried about gaining a large amount of weight. I didn't want to become unhealthy. It gave me a lot of insight on healthy options and diets. It helped me better understand my body and that what's good for me, may not be the same for others.
Hope this helps! :)
