I should preface this with a reminder that since beginning keto in Jan 2017, I have not experienced what I define as ‘real’ hunger. While eating SAD all my life I experienced relatively ‘normal’ hunger and satiety, but with keto not so much. Any hunger has always manifested as only very slight and fleeting - just a faint reminder and then gone. As for satiety, I eat to macros because I can always eat more. The macros - and my stable weight and body comp - tell me when I’ve eaten enough.
For whatever it’s worth - which may or may not be much - I just had the following experience. I have been taking lime juice, about a 1/4 cup mixed with soda water and/or Fresca, a couple of times during the evenings, generally once before my eve meal and once again afterwards. This to supplement citrate. I had also been taking about 1/4 cup of red wine vinegar diluted in 3/4 cup of plain water just before bed to supplement acetyl… For various reasons I had neglected the vinegar for more than a week. Mostly because my evening ‘schedule’ has been rather chaotic recently and I just keep forgetting.
Anyway, this past Friday (Feb 11) I drank my vinegar before and after my evening meal rather than the lime juice. My experience of the previous weeks when I drank vinegar at bed time was that I felt a little more ‘hunger’ by morning than usual, but still within the overall bonds of my keto experiences. Saturday morning, this was even more accentuated. In fact, I could say it was the first time since beginning keto that I actually awoke ‘hungry’!
My initial guess is that the vinegar suppresses glucose overnight and by morning the low glucose triggers the ‘hunger’. I haven’t tested this hypothesis with a CGM, but will do so the next time I buy a sensor. My previous CGM experiments generally showed my glucose the lowest in the hours before arising, then followed by the modest rise of the ‘dawn effect’.
Curiously, the hunger went away again as usual and only lasted slightly longer than my normal experience. But… and this is significant. Even though I ate only my normal keto coffee ‘breakfast’ and later at work a rather modest midday meal, my hunger never came back again even though it was a very busy day at Walmart. This even though I was very tired when I got home yesterday - it was the last day of 5 consecutive work shifts - and I went straight to bed. I did not eat supper nor take any citrate or vinegar. It’s already late morning on Sunday and I still feel no hunger. Although, I did have my morning keto coffee.
