The study itself seems reasonably good, beside being a such a small number, so call it a good start. I’ve got to say, though, that it brings back creepy feelings.
The place I worked for my last nearly 20 years did an employee health program starting around 2005, IIRC. They were slowly moving in the direction of requiring some sort of BMI metrics and the other side of that is requiring annual physicals, weigh-ins and lab work. There were statements, always denied, of mandatory diets and mandatory exercise periods. It hadn’t happened quite like a concentration camp when I retired at the end of 2015, but I remember getting a mandatory weigh in when I was just low carb, weighing 30-ish pounds more than I do now, and getting a stern talking to.
It seems like this study is reasonable, with CGMs and Keto Mojos, but it always makes me think there are going to be companies who think that’s too radical and they need to follow the USDA guidelines, the ones pretty much behind the whole obesity epidemic.
If they had said, “you’ve got a problem” and tried to help in some way other than mandatory “eat less move more” sessions, I’d feel better about it.
