As one of the most hardcore types of roadies, I've experienced many of the extremes of human endurance. Like the need for sodium, magnesium, and potassium from massive leg cramps, or calorie crashes when it feels like your tank runs so empty you hit a massive wall where your body all but quits.
One of the things I'm only just becoming self aware of is the need for iron/protein as a direct craving, not some common indirect theoretical knowledge.
I've been on the same basic daily diet for a year with very little variation. I've noticed times when I crave eating extra stuff. I used to be massively overweight, so I'm super aware of avoiding binge eating and most junk food. However, I've found a pattern where sometimes I need a fresh fruit, and others–I need something with protein and iron. If I go straight to those resources at the right time, the cravings stop. If I get it wrong, I feel hungry again and crave something more in a short amount of time.
I get the impression I was overweight when I was younger because I lacked the awareness to connect these dots... along with a nutrient poor base diet.
It is just a thought I've been mulling over in the back of my mind for a few days. I wonder if others are either more subconsciously able to crave a better available food that meets their needs, or if I just failed to RTFM when I was born and most people are aware of this kind of connection. So... are you self aware of different types of hungry where eating a small amount of the right thing can make the issue go away when you would otherwise eat too much?
Yes, my wife is always amazed or puzzled by how I know exactly what I'm missing. Like it will be I need peanuts, or greens, etc. Once I have those I instantly feel full and satisfied. If we don't have the specific Item my body signals I'm hungry and will nag me for food all day (i assume it hopes quantity will bring in the nutrients needed) There was recent science about the gut nerve signaling your brain when it needs things, and not a one way nerve from brain to gut like they previosuly thought
