Peak BHB concentration (C_max) and incremental area under the curve (iAUC) were significantly greater with 25 vs 12.5 g of BO-BD in both formulations. There were no significant differences in C_max or iAUC between formulations.

We conducted focus group discussions and interviews with national and regional key informants, older adult SNAP participants and SNAP-eligible nonparticipants, and food bank outreach staff. Discussions and interviews were recorded and transcribed verbatim to explore common themes. Older adults, key informants and outreach staff reported challenges faced when applying for and using SNAP, including feelings of shame. Older adults commented that benefit amounts don't increase proportionally to increasing food costs. Other barriers included difficulties applying due to challenges using or lack of access to technology and gathering the necessary information to apply.
