You are new, it’s normal. When I drastically change my woe (it wasn’t true for keto, though), I barely can eat in the beginning, I guess my body gets confused as it usually wants a lot of food. I’ve read this about many people, the beginning is easily odd. It will change with time, maybe.
Maybe not, there are such cases too. I had to wait until fat adaptation but since that, I am almost never hungry. I usually eat without any hunger as I just can’t wait for days to eat, I like to eat every day, it’s odd and often not pleasant not to. I eat a nice meal and it often satiates me for a day. It’s not a super rare thing.
Some people are never hungry, I heard. Well you do what you can, whatever body signs you get. I eat without hunger and appetite too, I feel the need for energy sometimes. I usually eat when it’s time, that isn’t so bad either (my mealtime is quite natural, I always ate my biggest meal around that time) but if I can’t, I wait.
(It’s a tad annoying if I am never hungry, though. I like to get my hunger back sometimes. I mean hunger before a meal, not during or after as I usually have it.)
I can do 1-2 meals on a carbier diet as well. Now that I am fat-adapted. My fat-adaptation wouldn’t last long on high-carb but still longer than myself
And I rarely needed to eat before lunch on high-carb. But some people always need their big breakfast. There are individual factors which have little to do with our way of eating.
Maybe some cases aren’t common but they are normal. And even if we are abnormal or special or weird, it’s not necessarily a problem. Why would it be?
Unless you absolutely can’t eat enough on keto. I’ve heard about such cases but it’s quite rare I think…?
