Have been keto / ZC since June 17. Lost over 60lbs. Very much fat adapted. Usually OMAD.
But the one thing I have never truly experienced is the “eat until satiety” bit.
Sometimes it 2 or 3 hours after I eat before I truly feel full.
If I ate until satiated I would probably explode before the feeling kicked in!
I don’t have anything helpful to add but sometimes around fasting I have something similar: not hunger, exactly, but the feeling that I could just keep eating, like there’s plenty of room.
My last few feast-before-fasting meals I’ve tried to really eat until I didn’t absolutely did not want to anymore (big meal, then some macadamia nuts, and then a whole avocado - aiming for that feeling that I actually really didn’t want another bite), and that’s worked for me in terms of the satiation. (It remains to be seen whether it works for health! If I’m on the forum in a few weeks complaining that my pants are tight… well, then it will be clear 
).
The dudes just did a podcast on this. I found it interesting and I realized that I may not be eating enough! And never ever would I have thought I would hear myself say that!!
I loved that bit of Dr Phinney’s on the podcast! Something like - you know you’ve had enough fat when you open the fridge and the butter no longer looks like something you want to eat (or was it the other way around? if the butter looks appealing, you haven’t had enough fat)
I’ve found that it really varies depending on how fatty my meal is. If I’m having something heavy on the fat I start feeling those the uuughhhh, can’t eat another bite business before I’m even finished. And if it’s something that isn’t very fatty I eat the meal and it takes some time for it to register that I am full. It’s weird now that I think about it. Maybe I need to up my fat!
Pretty sure I’m Leptin resistant. Always hungry on carbs even after a meal, even after waiting 20 minutes, even after… You get the picture. Less hungry, more often, but it’s still there a bit. Went to bed hungry last night, but didn’t feel I should add even more fat. Just recently was rereading an interview with Fung on this. Frustrating!
I’ve tried eating more, including higher fat. It knocks the hunger back, but I gain weight. I’ll give the podcast alisten. Thanks!

I listened to this and this week have ate 2 portions of pork belly and this is what triggered my thought process because I am genuinely eating enough. If / when I eat more I feel ILL about 2-3 hours after, but that ‘satiety / full’ signal does not set in for an hour or 2.
Right now, 3 hrs after eating, I feel like my tummy is overstretched, but 45 minutes after I ate I could have easily ate more.
Dysfunctional leptin! yes, its quite common for your cells to also become leptin resistant if you have also been insulin resistant for many years. The body stops listening eventually, was hoping mine would have started listening again by now.
Im the same way except its usually about 30-45 minutes after I stop eating that I feel full. Sometimes I’ll have a little to eat about 15-30 minutes before my meal to see if that helps kick in that satiety feeling at a more appropriate time. I could still continue to eat but I stop myself because I had plenty of food and then I wonder if I want more to eat because Im still hungry or if I just like the taste of foods. Then about 30-45 minutes later, I feel full and am glad I stopped eating when I did. I rarely get that “I feel satiated and don’t want any more food” feeling while eating a meal though. Ive been keto for 18 months, and I average about 75-80% fat per day.
Thanks for your reply, good to know I’m not alone on this. Fat % is about the same as yours.
Unfortunately I felt the podcast only proved how subjective satiety is. There were at least 2 different definitions offered, one by Phinney (don’t go away from the table hungry), and one by Carl (eat until you can’t eat anymore). To me those are completely different.
I find when I feel full a while after I ate it is because I finally drank a bunch of water. I think I would feel full while eating if I drank enough water before or during. I’m not talking gallons, but sometimes I forget to drink.
This confused me too. Pretty sure I also recall Richard previously saying something like "it doesn’t mean eat till you’re stuffed, it means eat till you’re no longer actually hungry and then stop… which is very different for me. But he didn’t correct Carl or debate it when it came up.
To be really honest I’m still struggling with the concept even though the dudes addressed my question on the episode. I didn’t feel like I came away from it with a fully resolved answer. (Sorry guys.)
Satiated for one person is totally different for another.
For me its a thought process, If I don’t stop now I will feel ill in about an hour but could eat more right now!
Maybe over time my hormonal signalling will repair itself and I will feel full whilst eating, but for the moment its a slow signal that takes about 1 hr kick in.
That kinda works for me, lol. But my wife can be ravenous and still find the idea of eating butter disgusting. So again, not a universal solution that can be applied to determine satiety.
My eating pattern definitely changed…
When I was low carb, not keto, I would eat meat, vegs and some whole wheat stuff, then feel full but not stuffed. Get hungry in two hours, snack on nuts. Then eat again in 2/3 hours. It was so annoying have to eat all the time.
Now there is no whole wheat stuff to fill my stomach, I don’t feel full by the same amount of meat and vegs, even with a lot more fat. I pretty much intuitively did this in the past few days : eat half of what i cooked with added fat, sit for 30-60 mins, if hungry, then i finish the other half. By the time i am done with the second half, i am usually “stuffed”. LOL. But then I usually go without eating for 10+hours after that., maybe just some fats in between.
So yeah, satiety signal changes. And mine is shifting to the new way of eating…
