I started Keto a few weeks ago, it really is amazing that although I am eating relatively little, I am rarely hungry, I almost have to remember to eat.
I hope to eventually incorporate IF into it.
I experienced the exact same thing.
I have a fridge full of herring - sometimes a bowl of that is all I eat all day. And I’m rarely hungry.
When I eat something with bread, though, I instantly bloat up and get hungry. It seems to block nutrient absorption so you’re hungry more and more, the more bread you eat.
I am thinking about shifting to a partial keto where I eat more veggies provided they don't contain more sugar than I can burn off during my daily bike ride. Since I ride late in the afternoon, I will eat nothing but protein afterward my workout or skip dinner altogether.
BTW, during the week I ride the stationary bike at my wellness center (it's free on Silver Sneakers) in front of a TV playing youtube videos of beautiful European bike rides (See HERE and HERE). This seems to be the best way to get in the hours of cardio because the time flies by. Other folks in my wellness center have started to join me in my daily rides so that makes it easier still...and more fun.
My wife and I really enjoy that we forget to eat, as well.
We mostly eat one meal a day, but not more than two, any longer.
