Bacigalupi, Paolo. The Windup Girl

Paolo Bacigalupi, The Windup Girl (2009).

Biopunk SF set in the 23rd century. It is a world in which everyone is very attuned to the calorific significance of everything that is going on around them, although the calorie hasn't quite taken over money's unit of account function.

Here is a snippet:
Chaiyanuchit remembered the beginning of the plagues. Not many could claim that. And when Jaidee was just a young draftee, he was lucky enough to work in the man’s office, bringing dispatches.
          Chaiyanuchit understood what was at stake, and what had to be done. When the borders needed closing, when ministries needed isolating, when Phuket and Chiang Mai needed razing, he did not hesitate. When jungle blooms exploded in the north, he burned and burned and burned, and when he took to the sky in His Majesty the King’s dirigible, Jaidee was blessed to ride with him.
         By then, they were only mopping up. AgriGen and PurCal and the rest were shipping their plague-resistant seeds and demanding exorbitant profits, and patriotic generippers were already working to crack the code of the calorie companies’ products, fighting to keep the Kingdom fed as Burma and the Vietnamese and the Khmers all fell. AgriGen and its ilk were threatening embargo over intellectual property infringement, but the Thai Kingdom was still alive. Against all odds, they were alive. As others were crushed under the calorie companies’ heels, the Kingdom stood strong.
