natural fats are generally healthy and keeps you satisfied for longer and in a less crashy way as opposed to sugars/carbohydrates in general
I feel like I experience a reduced need to eat and snack when my food includes natural fats, especially when in combination with protein
Am I missing something, why would you get less of any of those in a city? You would definitely go on more walks in a city, and I don’t see how water or sleep would change.
Only thing I can think of is air and noise pollution impacting quality of sleep and benefits from walking. No idea about the water though lol.
