Digestive processes are energy costing and if calorie intake is insufficient. In a bid to reduce energy expenditure, these processes can be down regulated resulting in symptoms such as bloating, constipation and/or diarrhea.
Now a tricky thing with this is that it if you are suffering digestive issues. It can be hard to tell that the cause of these symptoms in your specific case is low energy availability. However the reason it is worth flagging is that sometimes people are in a state of low energy availability and when they develop symptoms. They go through elimination diets or avoid perceived trigger foods (eggs, dairy, gluten etc) which ends up being
counterproductive due to making the energy availability problem worse.
A simplest solution is:
โ
Monitor for other symptoms of low energy availability if you suspect it is an issue.
โ
Prioritise eating enough food if you have any suspicion that it could be playing a role.
โ
Donโt increase output because you are eating more and in some cases you might have to pull back from your expenditure.
โ
Give it time and have patience as
sometimes it takes the body a while to recognise that there are sufficient calories consistently available, before it feels comfortable upregulating a bunch of functions.
Under fueling isnโt always the cause but itโs definitely more prevalent these days with the diet culture we live in today. Awareness is important so you can address it if relevant.
