While I don't struggle with intense hunger, Jarren, I do battle with cravings like sweets, and on occasion I do indeed get hungry. Your question really speaks to how individual our bodies are. For my part, if my portions creep larger, so does my hunger. Every time I have an overly big bowl of even salad and I can feel my stomach uncomfortably full, i know the next day I'll wake up hungry. The only way I've been able to manage that is periodic fasting. Doesn't work for everyone but it seems to help. I drink water, or sweetened lemonade (with Stevia). I honestly think that for many Americans at least, portion control is a very real battle. Every time I start spooning fragrant, freshly cooked wild rice into a bowl I get enthusiastic. I have to put some back (not always). I've tried, and sometimes it works, slowing way down, and letting fullness catch up to me.
To answer another question, I changed a LOT of things: how much I ate, when, where, how much time I took to prepare, switching out my activities so that food wasn't central to my life but ancillary. Every change I made shocked both my mind and body into transition.
Years ago I read somewhere to put your portions on smaller plates. Look, I understand that we're trying to fool the brain. However, for me that's actually worked. I have bought really pretty small china plates. When I lump my rice or whatever onto them it looks like Christmas dinner. I retired my huge huge dinner plates. Nature abhors a vacuum and boy will I fill it. I am quite convinced that in doing so I'm trying to fill empty places which have nothing to do with food. That, of course, is a whole other topic.
It's a journey, Jarren, all we can do is keep trying until something works, then change it again when it stops working, and keep a sense of humor in the process. That makes us prettier than any pretty body. I hope that helps.
