Cereal.
Probably one of the foods I miss most. It is very difficult to find no sugar cereal that doesn't taste like sawdust.
I found out though that cereal was one of my red flag foods. I would be hungry within twenty minutes after eating a bowl, and then let the grazing begin.
I do so much better with high protein. I get hungry within three hours and that is reasonable. It is a different hunger that can be managed.
Over the past two months however, it has become painfully obvious, my old habits are just below the surface.
