On one hand you'll get your DNA sampled and an "AI" to tell you what to eat, on the other hand we spend 10+ hours a day sitting, live in heavily polluted cities (light, noise, air), don't do anywhere close to enough physical activity. If you eat what's considered a healthy diet [0] these things will impact your life quality much more.
What people need is self control and education, we use food as a source of pleasure instead of seeing it as fuel (this could be a symptoms of an unhealthy lifestyle in general, but that's another topic). People eat 3 times a days + regular snack even if they are not hungry. We lost our ability to listen to our bodies, but luckily it's not very hard to learn it back. No one needs an AI to know that a bottle of coke a day, a bag of m&m's or a 500g cup of non dairy, gluten free, #FeelGood, #BodyPositity cup of ben& jerry's a has a net negative impact on your body.
The whole system is fucked from top to bottom, look at supermarkets, half of the aisles are full of colorful, family sized bags of candies, chocolate, ice creams, frozen junk and sodas with cute little mascots to attract kids. Society lost its way so bad that we now celebrate obesity and ill health. The obesity epidemic is an insult to humanity.
Sure, a tiny minority of people have very specific needs due to rare diseases that could benefits from these kind of studies. But for the rest of us avoiding processed food and not over eating is more than enough. If you gain a kilo every 3 months and have a sugar rush after every meal your brain is more than capable to know what's happening, it's a matter of taking personal responsibilities and facing your problems.

Healthy people (aka the vast majority people) don't need any "AI" or "machine learning" for that, just basic nutrition education and a pair of eyes to look at the nutritional facts of the products they're about to buy.
There is a step after which the returns are greatly diminished, and for the vast majority of people that step is way closer to "pay attention and educate yourself" than "do what this AI tells you to".

I'd like to know how they determine that. "AI" and "machine learning" aren't unbiased by nature: https://www.newscientist.com/article/2166207-discriminating-...
"We are endowed by Nature with an interest in our own well-being; but this very interest, when overindulged, becomes a vice. Nature has intermingled pleasure with necessary things – not in order that we should seek pleasure, but in order that the addition of pleasure may make the indispensable means of existence attractive to our eyes." - Seneca
[0] we all know what a healthy meal is, let's not pretend it's a secret, eating healthy doesn't mean hitting all your blood test metrics with a nanomole precision.
