Everyone's a unique case, I guess. It would be nice to meet someone who was totally happy with themselves just as they are. I have long suspected that body type has as much to do with inner consciousness and emotional state as it does with food intake.

For instance: a person might subconsciously want to be thin so as to not be seen. (I think I was like that. I wanted to become invisible when I was in school.) Another might want to be heavy, so as to have a sense of solidity and protection around themselves...("I can't be pushed around easily.") I've known cases of people who protected themselves from the possible dangers of romance by making themselves unattractive...perhaps through their clothing or their body weight, etc...

Everyone is playing a reality game in order to avoid what they're scared of and get what they want. The subconscious game may often be in direct conflict with the conscious plan, however. Some people seek romance constantly, for example, but as soon as they've got it, they sabotage it.

Anyway, to make a long story short, you can eat like a horse and still stay thin, you can eat normally and still get heavy. It's much more complex than just measuring food intake.
