Scary isn't it, the word fasting. Doesn't that mean starving? Well no it doesn't and let me tell you something. I fit the fasting into my own body timetable. I have never liked eating breakfast, ever. I used to force myself thinking 'Breakfast is the most important meal of the day' and it isn't. (By the way, that phrase is a slogan that was invented in the mid 19th century by Seventh Day Adventists James Caleb Jackson and John Harvey Kellogg to sell their newly invented breakfast cereals.) I'm never hungry in the morning.
Also, over the last 20 years I have taken sleeping pills to get to sleep and they make you really hungry in the middle of the night and sometimes I would be scrambling around for something to eat at midnight.
So I use this, the biggest rule in Keto. If you are not hungry do not eat. That's all you have to do.
So, when I wake up in the morning during the week at around 6.30 - 7.00am, I want to have some time with my husband before he goes to work. So he makes us a cup of coffee with cream in it - which is the most exquisite drink in the world - and we have a natter. That coffee because it has no sugar in it (I use equal) and high fat with real cream doesn't spike insulin so even though I am drinking something so filling and delicious my body isn't registering it as food. What it does is fills me up until the afternoon. I won't get hungry until between 1 and sometime 3 or 4 pm. In the beginning of Keto I ate around 12.30 - 1 because my head was telling me that it was time to eat but after a while I learned the difference between head hunger and body hunger.
Head hunger and body hunger
Heat hunger is an amalgamation of a few things.
