Food and the sitting
Part 1 has two editions and the meditation is identical in both. Detox adds optional plant-based menus and hydration prompts on top of the same sittings. It is lifestyle guidance, not a diet and not medical advice — and the reason it exists is narrower than the word detox suggests: what you eat shows up in the next morning's sitting.
The measuring instrument is the sitting, not the scale
Ten years of eating experiments taught me one thing worth passing on. If I ate late, I did not get up at half past four. If I ate something heavy, the next morning's sitting was dull, and I sat down later or did not want to sit at all. Practice was the instrument. Without it, none of the eating meant anything — I have watched people go through the same diets with no practice and learn nothing, because there was nothing to read the result on.
So the instruction in the Detox edition is not "eat this". It is: change something, then read the next morning. Your body will answer more usefully than any food list.
Two rules that survived every stage
Change one thing at a time, and understand why. Ten changes at once tell you nothing about any of them.
Replace rather than remove. Taking a food out without knowing what covers it is how people end up tired and calling it purification. When I dropped dairy, something had to carry the calcium; when I dropped meat, something had to carry the protein. Knowing what replaces what is the difference between an experiment and a slow deficiency.
What "purification" honestly means
The body already detoxifies itself: that is what the liver and kidneys do, continuously, with no help from a menu. No food and no fast cleans an organ, and this site will never tell you otherwise.
What can change is simpler and worth more: lighter digestion in the evening, steadier sleep, mornings that begin without heaviness, and a body that is easier to sit still in for half an hour. That is the whole claim. It is modest, it is checkable by you within a week, and it is enough.
What it does to the mind
Two things, in my experience. Sitting with a full stomach is mostly digestion; sitting with a half-empty one is mostly practice — which is why the traditional advice is to sit an hour or two after a meal, or best of all before breakfast. And the training transfers: a craving is a sensation plus a story, and eating attentively is the same skill as sitting attentively, practised three times a day with something you cannot avoid.
For what research supports, rather than what people say: mindfulness-based programmes show moderate effects on weight and larger effects on obesity-related eating behaviour (Carrière et al., 2018), and meditation lowers physiological markers of stress (Pascoe et al., 2017). Nothing beyond that is promised here.
Where the experiments go wrong
Mine went wrong for years, and the failure is instructive. On fruit alone I had energy and almost no emotional weather, and I mistook the flatness for progress because it resembled the calm after a retreat. My circle narrowed to people who ate the same way. I got thin and let it happen. Later I went further still — days without food or water — and what I found at the end was not clarity but a body that could not climb stairs, and two years of ordinary eating to repair it.
The Buddha's path is described as the one that avoids two extremes: indulging the senses and tormenting the body. Ascetic pride is still pride, and a body starved for the sake of the mind is still being used as an argument. At Pa-Auk the monks accept whatever food is offered, eat it slowly, and are not working on the body at all — they are working on the mind, and the food does not reach that work.
What not to do during the course
Do not fast while you meditate. Do not start a restrictive diet in the same week you start a meditation course: you will not know which change caused what, and both will get harder. If you are pregnant or breastfeeding, diabetic, underweight, taking medication that depends on food, or have any history of an eating disorder, take the Classic edition and talk to a clinician before changing how you eat. Read the safety page first in any case.
