Fasting and calories

(Richard M) #1

I am still trying to figure my body on the Keto way of life.

I have fasted for 48 hours on multiple occasions and felt great.
But two occasions I have not been able to eat my daily caloric intake of 1800-2000, because of feeling full, and the next day I felt tired, lethargic, sleepy and irritable and the list goes on. My fat and protein consumption was fine.
So the next day I eat TMAD instead of my normal OMAD the next day. Trying to feel better. Which I do.
I’m drinking lots of water with salt in it. I do have black coffee every morning.
Is there any similarities to eating lest calories and feeling tired or is it something that just happens. But how do I do fine fasting for 48 hours and not feeling any of these effects.

Was there some nutrient or supplement i need to take? What did I do wrong?

So, how can I go form 48 hours of fasting and feel great to eating a meal until I am full but below my Caloric intake and feeling very tired or lethargic or sleepy…

Because we’re not mechanical watches that do exactly the same thing at the same time as long as you wind it. We are complex biochemical processes that interact continually, produce resultant outputs that then in turn interact to produce additional complexity. The big picture is relatively simple. The detailed picture looks more like the Mandelbrot set.

The Mandelbrot set has become popular outside mathematics both for its aesthetic appeal and as an example of a complex structure arising from the application of simple rules. It is one of the best-known examples of mathematical visualization and mathematical beauty and motif.

CICO looks only at the big picture of energy management and ultimately fails precisely because it ignores the complexity of the detailed picture.

I don’t feel tired when I eat too less, just hungry so I eat and it gets resolved easily…
But indeed, fasting for 48 hours is very different from eating every day but too little, I can handle the previous better myself (if I manage to skip a meal, I rarely do that). I find it normal as I always worked liked this. 0 calorie works better than 1200 :smiley: (1800-2000 is plenty for my body and anyway, being close to carnivore changed my minimal calories. Today I totally stuffed myself on TMAD and reached 1300. It’s exceptionally low but happens. Just like 2200 kcal carni days. I am no robot, my days are different and it’s perfectly normal.)

I have this with meals too. Skipping a meal is easier than making it small, I am way more hungrier when I do the latest. But it’s way more prominent with days. My body is patient and often wait until late but if I ate too little (calories or protein), I get hungry in the end.

You do right if you do TMAD if your OMAD meal is too small, I do the same.

I often wanted to the fake style of intermittent fasting, where you eat one small meal per day, like 500 calories. I either have to not eat at all or eat as much as I want. I can’t do the small meal idea.

These are symptoms of not getting enough to eat. When you fast, fast. When you eat, feast!

These are hunger signals, also add feeling cold for no good reason.
