I think I am misunderstanding something, how did you cut your cooking/cleaning up time down to 4 minutes a day? And, are you eating the same food every day now?
sorry, I just eat a little bit of something and cook rice once every 2 days. yes, I eat largely the same food every day. I assumed that would drive me insane, but I just don't mind it. started squeezing half an avocado into every bowl, and that has been a big upgrade.
Interesting, can you provide a source? I suspect you may be referring to calorie restricted and not nutrient deficient diets. The former may lead to a longer lifespan and a better health but the latter will lead to health issues or at least degrade your quality of life.
