I feel disappointed with general dietary guidance. Carbs seem like heroin for some people and they really can’t help themselves. So judge, no. Feel sorry, for sure.
All that said, some grocery stores use club cards and use those to track buying habits. I’ve got to believe theirs amazing data there if the data could be tied back to the health metrics of the consumers. While it wouldn’t be “clean” trends would have to fall out.
All. The. Time. Especially at Costco. It seems like everyone at Costco (besides me) love buying those mega packages of croissants where each croissant is like the size of a dinner plate. One time I was at the store and this 10 yr old girl was begging her mom for cream cheese. The mom was telling her no, I won’t buy that junk, yet when looking at her cart, she had a few boxes of sugary cereal and 2 loaves of bread, among other crappy carbage. Then she gave me a look with a smile like we were having a mom moment together agreeing how kids always want the “junk” food. If she only knew what I was really thinking. Then sometimes I will see keto foods in someones cart and I get my hopes up that I found a keto person at the store only to be dashed by some crappy carbage hiding in various places around the cart.
Canned cat food is fairly expensive by volume, most of what I eat is cheaper.
I normally just get the judging looks when I am walking around shopping and shoving a packet of pre-cooked bacon in my mouth! 
I most certainly look at other peoples baskets, judge, kinda, TBH. I used to be that guy that had a cart full of processed junk food, sweets, and beer. Now I am the guy with veggies, more veggies, and then some coconut milk and extra virgin coconut oil in the biggest possible container.
I find it hard not to judge when I see a parent with a fat little baby and all the carbs in their cart. At least adults have a choice to learn or not but the children.
Yesterday I was in the checkout line behind a desperately heavy woman and watched in silent dismay as she unloaded her cart of fat free and lowfat items. I couldn’t help but wonder if her choices were due to her condition or her condition was due to the choices. She might benefit from new ideas about dietary fat but it seemed impossibly awkward to say anything.
It is impossibly awkward 
This is why I’m so frustrated with the health authorities that refuse to recognise the health benefits of low carb / keto diets. I remember trying to loose the baby weight after the birth of my youngest. I read a Norwegian equivalent to Weight Watchers book, and made fat free foods I didn’t like for months. Needless to say I lost weight (I didn’t eat much, as I didn’t care for the food), but it was impossible to sustain! The hunger and cravings eventually drove me crazy. I feel so bad for people with these low fat ‘foods’ in their shopping carts, because I know their struggle! I know that although they might loose, it will all come back with a little more to top things off 
It’s agony - I know what works! It worked for me, and so, so many others. Hopefully will all the research eventually be taken seriously, and the dietary guidelines changed. In the meantime we’ll just have to take responsibility for our own health ourselves.
I agree but think it is a combination of the “health authorities” as well as the companies that manufacture these foods not wanting people to realize the products they are purchasing are slowly killing them. Could you imagine if suddenly everyone realized they have to stop buying the processed, fat free crap? I wonder how much money companies that make that stuff would stand to lose. Im guessing they could quite possibly quickly go bankrupt and those executives that have million dollar salaries because of this crap would be willing to pay any price to keep their products in the store, whether its manipulating the health reports or quieting those trying to inform the public.
I really don’t want to believe that people/companies are that cynical, but they probably are. It’s awful 
I know. Me either. But Im sure it holds true in a lot of instances, perhaps not all. Why do you think the sugar industry paid off Harvard scientists to blame fat as the villain in the 60’s, not sugar as their research was saying?
The food industry is in business to make a profit, not improve your health. Their business is not about making any healthy product, only SELLING their products for profit. If it makes people buy more of their product, they will advertise it using any legal means afforded to them. NEVER fool yourself into thinking these companies have scruples or morals. Business is business, and profit is the #1 goal of business.
I dont really think so actually. Companies change depending on demand - they used to sell higher fat snacks in the past and changed to low fat because high fat was no longer selling.
Mcdonalds changed from lard to vegetable oil because people viewed the lard as unhealthy.
Mcdonalds will gladly give you food with no bun, extra bacon, hamburger patty on a salad, etc
As the market changes (e.g. truth comes out about fat) so eill the products. Instead of low fat it will proclaim “Low sugar! Full of healthy saturated fats!” etc because that is what people will buy
You can see that in stuff like halo top or keto products already
Companies dont really care WHAT you are buying, honestly, as long as you buy from THEM.
Adapt or die is one of the first rules of business.
Coke exhibits the exact same thing. First coke. Then calories became a concern so they offered diet coke. Now artificial sweeteners are unpopular so they are researching how to do stevia or erythritol for a new product to roll out because that is what people want.
Why would they want their own customers to die? A long lived loyal customer is one buying your products for 90 years instead of 70.
Now there are some areas where there has been definite influence: sugar industry, and wheat and corn lobbies. Because if it comes out what theyre selling is harmful they cant just change their product. Theyre only selling one thing. If sugar is no longer in favor, theyre out if the job.
But companies in general will change as demand does, and dont generally offer keto options now because the demand is not large enough for it to be profitable to do so
But ultimately, isn’t this initially the authorities fault? They gave the public the advice to cut fat, and so the demand for low fat products increased. The industry simply adhered to this to, as you pointed out, make money. I believe that if the guidelines were changed, the demand would reverse back to real food, which in turn would drive the industry to supply. Perhaps I’m over simplifying, but this is basically how it works isn’t it?
Very true. I guess thats the reason Im not a business person, lol. Thanks for that point of view
