Why am I STARVING some days and totally fine on others, when fasting?

‘’In the world of hunger and satiety, the hormones in the bloodstream talk to our brain to tell it whether we should eat more food, or if we’re full. The part of the brain that determines whether our body is rich in energy or if it’s poor in energy - whether or not we’re hungry - is called the hypothalamus. 

Our brains are also constantly communicating with our gut. When we’ve eaten, the stomach will be pretty full with food. If we haven’t eaten in a while, our stomachs are empty and can start talking to us. It starts making noises and actually starts to growl. If you listen closely, the stomach is saying ghrelin… Ghrelin is the name of the hormone that’s released into the blood stream to tell the hypothalamus that we’re hungry and to motivate us to find some food (Kahn, 2021). Beautiful, right?

So let’s bring this back to fasting. We all have a fasting muscle that we need to stretch and relax according to how we feel on each particular day, in each particular hour! There is not one size fits all, because one size will never fit all. You are in charge of your fasting muscle and it’s up to you how you want to use it – it’s up to you what you want the outcome to be. 

There is concern that by promoting intermittent fasting, we are, perhaps unintentionally, encouraging extreme behaviours such as bingeing.  However, moderate proponents of fasting have a different, more balanced take; eat sensibly most of the time to improve biomarkers of disease, reduce oxidative stress and preserve learning and memory function (Collier, 2013).’’
