While I would bet that the general idea that few people lead healthy lifestyles is correct, the study is somewhat misleading, given how they measured the "healthy" amount of physical activity [0]: "While attending the MEC, participants were instructed to wear an ActiGraph 7164 accelerometer (ActiGraph LLC) during all activities except water-based activities and while sleeping. The accelerometer measured the frequency, intensity, and duration of physical activity by generating an activity count proportional to the measured acceleration." and dietary behavior [1]: "Data from the Dietary Data Collection system were used to compute a Healthy Eating Index (HEI) score for each study participant. The HEI-2005 [2] was developed by the US Department of Agriculture as an indicator of dietary quality. The HEI has 12 components (total fruit; whole fruit; total vegetable; dark green, orange vegetable and legumes; total grain; whole grain; milk; meat and beans; oil; saturated fats; sodium; and calories from solid fats, alcoholic beverages, and added sugars), with each component individually scored and a maximum total score of 100. A higher score reflects closer adherence to the dietary guidelines for Americans." I would guess the number is not higher than the 5-10% range, but 2,7% seems too low. Let's say you swim 5x a week and follow a ketogenic/low-carb diet, the study would have you classified as unhealthy. The HEI-2005 [2] is already outdated (revised in 2010) and it is probably not the "optimal" diet either.

>the study is somewhat misleading, given how they measured the "healthy" How is it "misleading" when they clearly explain the definition of their measures?

  I'd go with "inaccurate" then.

  What if they said they were measuring how many of test subjects where human and then explicitly say the measure humans as having above 1 meter tail. Now they can, without being misleading at all, claim there were no humans in the last us census. Your definition of measurement must be representative of the category you claim to be measuring. It is misleading to say there are no humans in the American census when your measurement for human is non-representive just like it is misleading to say that hardly any Americans are healthy when you're measurement fails to capture most healthy subjects.

A ketogenic diet is unhealthy

  You think you can just state that, uncontroversially, with no sources to back up your claim? I don't have an opinion either way, but there's a lot of science that contradicts your statement: https://www.reddit.com/r/ketoscience https://www.reddit.com/r/ketoscience

  There is literally no 100% healthy diet. Water takes minerals from your body with sweat and pee, water is unhealthy. Unhealthy is 90% of food and "diets" that were created in last a few decades, every other known for longer (hundreds of years) diet, keto or paleo has its disadvantages and advantages, but it's much better then fast food, frozen pizza or ready to microwave stuff.

  Ketogenic diets MIGHT be (but almost certainly aren't) unhealthy. Eating the amount of sugars that most Americans do is absolutely unhealthy. I know that I feel a billion times better when I reduce my carb intake, even not to ketogenic levels. Further, doing a ketogenic diet for about a year got me down to a weight low enough that I could exercise more regularly and effectively, with fewer injuries. Never mind the emotional health changes associated with not being an obese 20 year old. I started when I was 17 and spent a week in one of the top children's hospitals in the country for unrelated things — all the doctors there were very approving of what I was doing.

    It's not a might, it absolutely is for some. I'm one of them. I tried keto for close to a year and my blood sugar shot up to being pre-diabetic. Why was that? Medium-Chain Acyl-CoA Dehydrogenase (MCAD) Deficiency[1]. It produces an enzyme that is involved in breaking down fat from food and stored body fat into energy. Because people lack this energy source, affected individuals must keep their blood sugar levels up by eating regularly to avoid acute episodes of lethargy, seizures and coma. The condition can lead to sudden death unless it is diagnosed and proper dietary interventions are followed. So when you're keto, eating lots of fat and little carbohydrates, which doesn't keep your blood sugar up, you can get into trouble. Is keto unhealthy for everyone? No. Is it healthy for everyone? Definitely not. [1] https://en.wikipedia.org/wiki/Medium-chain_acyl-coenzyme_A_dehydrogenase_deficiency https://en.wikipedia.org/wiki/Medium-chain_acyl-coenzyme_A_d...
