To use Thomas Sowell’s term, this is “The Empire Fighting Back”. If overweight and unhealthy people actually do figure out that eliminating carbs is the secret for most of them to get healthy again, literally MILLIONS of jobs would be lost.
...and we can’t have that.
Just a personal observation... I have known a lot, a whole lot of overweight people who seemed pretty healthy. When they give up “carbs” most of them actually do lose some weight at first. Then most of them discover all the high protein snacks that are available these days and start gaining the weight back. Only they seem grumpier than they were before. Then after awhile most of them start having health problems possibly related to the lack of variety in their diet.
I literally have known a slew of people who have gone on high protein diets, many of them are evangelists for the cause in the few months after they start, but I don't know any who kept the weight off or seemed any healthier in the long term.
