Why You Should Never Make Important Decisions on an Empty Stomach, Including What to Buy When Shopping

Ghrelin is a hormone that is produced in the stomach and released before meals to increase appetite [1].

This means it is best not to do the grocery shopping when we are hungry, as such timing is likely to ensure a whole lot of junk food makes it into the trolley. But research shows that it isn’t just food related choices that could suffer when we are peckish.

It turns out we are best to avoid making any decisions on an empty stomach.

Karolina Skibicka one of the researchers of this hormone says it can cause increased impulsive behaviour. [1]

A ghrelin injection into the brain resulted in impulsive behaviour in rats and caused the same type of changes in dopamine-related genes and enzymes as can be seen in ADHD and OCD [1].

Researchers are also looking at how this applies to the treatment of psychiatric disorders characterised by impulse control issues [1].

I also believe that low blood sugar levels can also significantly influence brain function including behavioural and emotional issues.

If you combine both of these scenarios which often occur together ie an empty stomach and low blood sugar, it makes a powerful duo and may make you much more vulnerable to many things as well as making impulsive and unwise choices. This also applies to children.

Avoid sweet foods and refined carbs when hungry as this can cause a reactionary drop in blood sugar later and can contribute to cravings, which creates a vicious cycle, thus compounding the whole problem.


Start the day off for yourself and your children
with a protein breakfast or a protein shake.
