Why should you consider kicking the coffee habit or at least cutting back?

Caffeine is a stimulant which increases mental alertness by blocking receptors for adenosine, a brain neurotransmitter which has a central role in sleep.

Blood sugar balance is regulated by many hormones in the body including insulin, glucagon, cortisol and adrenaline.

Drinking coffee (& other caffeine containing drinks) creates a stress response in the body and the release of cortisol, the stress hormone. ⠀


  • Controls blood sugar levels
  • Helps reduce inflammation
  • Helps regulate metabolism
  • Is central to the body’s ‘fight-or-flight’ response, along with adrenaline

Is important to health but too much of it can wreak havoc in the body. ⠀

How the body reacts to caffeine varies from person to person. If you’re sensitive to it you may experience an increase in your heart and breathing rate and feeling jittery, nervous or restless or of being on a blood sugar rollercoaster 🎢.

It has a long half-life of around 5 hours (but this also varies from person to person) which means there will still be 50% of caffeine in your system five hours after drinking. This is why caffeine can affect sleep 😴so much.

It is also an anti nutrient which means it impairs the absorption of vitamins and minerals like B vitamins and iron as well as certain medications like thyroid medicines.⠀

✖ No caffeine after 12pm⠀
✔ Limit the number of cups to 1-2/day⠀
✖ Don’t drink at or around meal times ⠀
✔ Swap for decaf or caffeine free alternatives such as chicory or dandelion⠀
✔ Remember black tea also contains caffeine so switch to caffeine free options later in the day⠀

Take home point is enjoy your coffee in the morning, well apart from breakfast (to avoid it’s anti nutrient effect).

Consider switching to decaf or other caffeine free alternatives if you are sensitive to it.
