The similarities included being moderate carbohydrate/ low grain/ no added sugars, nine servings of low sugar fruits and non starchy vegetables each day, plenty of other fibre and mineral rich foods (certain nuts, seeds, beans, lentils), live yoghurt and a freeze dried probiotic supplement (Lactobacillus, Bifida sp).
I enjoy traditional aged cheeses but was minimising saturated animal fats at that time, so not daily. No other fermented foods that I can remember. So overall a prebiotic rich but not probiotic rich diet.
Alongside that daily physical activity (easy pace walking) *very slowly* working up to four hours a week of moderate to intense formal exercise (various gym classes) I improved my physical and mental health enough to be able to work and study again.
I had many clients improve their mental health (most often depression and stress/ anxiety) through targeted diet and lifestyle modification, tho much less ‘hardcore’ than mine ended up!
I am convinced some of the improvements are to do with taking control/ ownership of our health, and gaining confidence/ self belief.
