“It’s a Lifestyle, NOT a diet”


How stressful is your life?

We all instinctively know that long-term stress is not good for us but perhaps not exactly why & how. Well, it’s all to do with the stress hormone “cortisol”..

In the short term, cortisol production is a perfectly natural response to the “fight or flight” instinct. It actually reduces inflammation and suppresses appetite and is therefore ketogenic. However, longer-term, continuous exposure to cortisol will have the exact opposite effect: suppression of the immune system & increase in inflammation. Since long-term inflammation is something to be avoided at all costs, this is not good news for those seeking the LIHF Lifestyle!

Stress & Exercise

Stress is also going to have an adverse effect on your exercise, in particular any improvement in results. This section from the book “Body by Science” sums it up nicely:


Stress affects your exercise

Undermining Your Inflammation Pyramid

Let us now consider stress as part of the Inflammation Pyramid. The IP should not be considered solely in the dietary context. Yes, diet plays a large part in determining what inflames you but other “substances” or hormones such as insulin & cortisol produced by the body itself also have a major say in what is going on. Hence, it’s no use diligently determining your IP in terms of diet when long-term stress (cortisol) is sitting firmly at the base undermining everything!

That is why this game is an entire lifestyle & not just a diet.

  1. Stress has a big negative effect on ketone production. You see a lot of people posting about how they have been strict keto but their levels have gone done…. but probably haven’t considered they have just worked a 50 hour week or something.

    • Yup. The modern way of life has “normalised” high levels of stress but there’s nothing normal about it at all. It is a huge killer 👎
