John Varley's 8 Worlds books (pre- and post-reboot) have had to colonize the rocks of the Solar system, tho they're not that technical, and he rarely moves past the Moon. Also Gaea (Titan, Wizard, Demon) has an extremely alien habitat; there are other Gaea creatures, just the protagonist one is crazy but also Human-friendly.
Vernor Vinge's A Deepness in the Sky is about life on STL, multi-generation starships.
Bruce Sterling's Schismatrix is mostly set in habitats, asteroid mining, and Martian terraforming, but also a very alien hive.
- NEVER BORN. “You mean we all came from Earth?” said Nikolai, unbelieving.
“Yes,” the holo said kindly. “The first true settlers in space were born on Earth—produced by sexual means. Of course, hundred of years have passed since then. You are a Shaper. Shapers are never born.”
“Who lives on Earth now?”
“Human beings.”
“Ohhhh,” said Nikolai, his falling tones betraying a rapid loss of interest.
I follow a simple diet called "half". I eat a half portion of whatever I'd like. I don't eat any better or worse, just less of it. Did you know a frozen burrito has 300+ calories? Eat one, not two. Portion controls are essential, don't get a tub of ice cream, get a box of little ice creams, and then eat one instead of gobbling two or more. Giant bowl of pasta? Half now, half goes in the fridge for tomorrow, instead of packing my gut full.
I probably cheat enough that I'm getting 2/3 or 3/4 of my full calorie intake, but it's good enough that I've lost 30 lbs in a couple years, I'm not putting it back on, and it's required no real hardship.
