But if someone has just worked for a couple of weeks to get nicely into keto, for example, they may not want to ruin it in a day. Likewise those on maybe a Paleo diet who know once they go carbing it can be harder to go back.

Maybe they are hosting someone in such a situation and want to make it easier for their guests.
