Agree. Too many ‘diets’ are focused on eating differently for our body. It’s such a generic motivator. It’s interesting you say greater productivity inspired you to change the way you eat. I think diets need to be more creative in how they are marketed.
I’m also changing the way I eat: for productivity, but also for performance in hobbies, to be less cranky with my family, and other reasons that aren’t solely to do with my body.
Cheers for sharing your experience. And good on you for making the effort to make positive changes in your life.
