Why would cell phone data help?

Genuine question... answers?

Most studies use self-reported behaviors for how people behave. More invasive studies (as some people have mentioned in this comment section) show that self reporting is inaccurate and, for example, people eat many more calories than they self report. If you have some system of automatic recording of behavior, which smart-phones might be able to do, and individual DNA results, then these large scale studies might be able to tease out what is healthy behavior for people with specific DNA.

> If you cherry-pick different studies you might actually find that consuming large amount of plants stresses our digestive system way more than a fatty steak with potatoes. You really, REALLY, believe with all information being out there nowadays that a diet of only "fatty steak with potatoes" will be healthier for humans that the "balanced WFPB diet" that is nutritionfacts.org claims is scientifically proven to be…

The keto diet's main difficulties are the prevalence and preponderance of available sugary foods, the near inability to eat socially, and the extreme difficulty in adopting the diet in the first 3 weeks for people regularly consuming 200g+ of carbohydrates a day. The raw diet is mostly a trendy thing people write about. The bioavailability of nutrients in many raw foods is just too meh. We know what the best diet is.…

> We know what the best diet is. A plant and fish based diet with small amounts of other meat.

Nope. Fish (most fish) as a central part of diet, will contribute a lot to build up of heavy metals in humans. And what is "small amounts of other meat"? 3x per week? This is basically an omnivorous diet. Compared to the SAD is probably just the junk cut out.

This, SAD-processed, is a very unhealthy diet, compared to a balanced WFPB diet. There are lots of studies to back this up.

> - Companies are making our produce harder to digest as they try and make products with a longer shelf life.

Yups.

> - Eating industrially produced meat (of any sort) is very unhealthy and in many ways unsafe.

Not a problem for those eating WFPB.

> - This entire discussion removes dairy from the equation, which is a large part of the puzzle for most people.

Dairy is a killer. Prolly more so than meat.

> - The low-carb vegan and the low-carb omnivore are far better off than anyone consuming 200g+ of carbohydrates a day.

Any study on this?

There is a lot of studies (long running, with large size populations) claiming the opposite. Here some arguments: http://www.masteringdiabetes.org/ketosis-ketogenic-diets-mis...

> - Hydroponically grown carrots taste gross.

Personal taste. It prolly has less phytonutrients. Not sure how this is an important consideration.

The site you linked is thick which propaganda which makes me doubt your bias and arguments. Choosing your sources is important for making a compelling argument.

One man's truth is another's propaganda, what are your sources? (I've shown mine, and I must say it's pretty convincing and lines up with what I already knew about the human body)

I'm not at all saying there's no use for keto, I just think it should never be a mainstream diet (but something applied in specific cases, under medical supervision). As far as sci evidence goes, WFPB seems to be the "best" diet for the human species as a whole.

Thanks - is there any literature that you are aware of on this so I can get started?

Googling "problems with self-reporting in diet studies" gives a good listing of scientific papers for me. Of course such a search is screaming out "confirmation bias", but it is still useful I think. This[1] is one study that seems to cover what I was talking about, although I have not read it in full.

If you want to take a deep dive into a subject, search for a recent paper on the subject and as you read it the paper will reference other papers, especially in the introduction. Here is where you can find possibly a more relevant paper on the subject. Read that paper and repeat. Soon you will have a decent idea of what is going on in the field. Hard to do if you don't know the jargon and the mathematical methods though.
