I used to track daily nutrients for a couple of months, but I found it a waste of my time - at least 1 hour per day. My diet hasn't changed at all and I'm getting enough nutrients - at least judging after the (biased) nutritional software. I didn't outline any diet - only suggestions. I'm certainly not a vegetarian and I didn't go into animal products in that article. It was an introduction only, that's all.
If anybody wants to track calories and nutrients, I suggested nutritiondata.self.com. But I don't do it anymore. Because once you know the basics, there is no added return. Frankly, from what I talked to people, many find out about the CR experiments on animals and would give CRON a try, but counting calories and nutrients takes a lot of time and they give up.
The population practicing CR is a minority, so I went after the lowest mortality BMI in general. Because supposedly one practices CRON to decrease their mortality risk, thereby increasing their lifespan if not healthspan. And that is the BMI people should be after when embarking on CRON. You may reap the benefits of longevity if your BMI falls to the lower limit of the normal, but you don't want to decrease it further.
And as a side note, the long-lived people I met as a geriatrician are those of normal weight where the BMI tends to the average. They were thin, but not skinny. Sure, this is anecdotal evidence, so use the BMI study I quoted here because the larger the sample, the more trustworthy the results are.
