I think this is a huge missing feature. I can't believe that even after 3 years they still don't have this functionality. Lots of other apps have this, but I'm already integrated with fitbit (watch and scale) so I'd like to stick with them. Setting an alarm every day isn't a solution. This should be something the app can do. Especially since you can set up a calorie deficit plan...
I see you can add a "stay hydrated" reminder if you go into your watch -> health & wellness reminders settings....so why not food?
