I am still coming to grips with eating normal size portions. They seem utterly tiny to me.
Obviously if I am posting in this age group I can remember when it was rare that families dined out. We ate at regular mealtimes and the only snack was the after school snack. Convenience foods were very rare in the pantry. If you look at movies filmed in the 60s and 70s, people are so thin. By my today eyes, everyone from that time looks like they have pipe cleaner arms and legs!! The "jocks" in the movies back then, which were supposed to be the bigger, buffer guys, would be relatively skinny men by today's standards. I don't recall that the food from back then was health-conscious per say; there was just much smaller portions of it. I'm pretty sure I drank mostly water and milk during childhood. I do not remember going through a drive-thru until I was in my early teens and it would be a rare, after swim meet lunch.
The convenience food and restaurant landscape changed pretty rapidly by the time I was in high school. And somewhere along the way, so did my perception of what was a normal size portion!
Obviously I am eating at a calorie deficit for the near future until I reach a healthy weight. After that, I have to eat at a maintenance level. I am uneasy that I won't be successful re-training myself to accept what is a normal portion of food : /
