Type 1s actually benefit from the widespread obesity, since it sends a lot of money into drugs and monitors that both type 1 and type 2 use. :)
I argue the opposite in that Nightscout and other initiatives that predominately serve the Type 1 community help push the advancement of monitoring, etc. that benefit the rest.
Thought on treating type 2 is also evolving in ways that don’t benefit type 1 as much. For example, the trend is for pre-diabetes to be taken seriously and detected earlier.
