YANBU, the "eat badly" plate is awful. It's a recipe for metabolic syndromes, t2 diabetes, thyroid problems, obesity etc, even more so for people with any sort of genetic susceptibility to developing those conditions (and that's a very large % of the population).
10 or 11 years ago when I first went low carb, people looked at me like I had 2 heads when I said I'd cut almost all grains and white potatoes from my diet. I was asked quite a lot about what I was eating because I lost over 6 stones. Most people were horrified and said "I could never give up bread" (which is actually what I thought, before I did).
Now low carb/grain free, high fat moderate protein is teetering on the edge of dietary normality! People hardly raise an eyebrow now when I say I eat Lchf/Paleo. It's a revolution driven by people's ability to share their success and experiences on social media. So many people seeing that the official guidelines are flawed and don't work well for their own health or their family's health.
Without trying to sound paranoid, Big Food/Big Agri/Big Pharma are doing their very best to undermine this to protect their own interests (guidelines are by and large pushed/funded by them).
Look at the Noakes trial in SA at the moment, as just one example.
Here in the U.K. Phcuk (public health collaboration, U.K.) is a new group of professionals working to change the guidelines to a much lower carb, real food diet with plenty of natural fats, worth a look at if you are interested (info is free but donations welcome). I have donated a little to them myself.
Other good, sensible sources of information are Marksdailyapple blog, Dietdoctor Lchf blog, robbwolf.com... plenty of science and studies, not just anecdotes (plenty of those too of course!).
