Seems to me that the 'solution' is to acknowledge that the one-size-fits-all approach to diet does not work. Low carb, high carb, high protein, vegetarian....they all can work for different people. The government should step away from trying to endorse any specific dietary guideline, and just present different dietary paths to healthy eating, and let the individual determine what works best for them. After all, it was the government that pushed the carb-heavy approach that adversely impacted a large segment of the population.

For me, low carb works because I do not do well with calorie deficits. But I do not care what other folks want to do, as long as it works for them. I do advocate for low carb to friends and acquaintances that are looking to get control of their weight, but I don't go beyond that.

'Wise' government is not wise.
Government should be more about helping the citizenry to get good information and less about being our mother and father.
One size does not fit all.
Everyone is different, see above.
