Be amazed all you want, but you're conflating two different issues, as does everyone who discusses it the way you do. Your attitude on this is actually a public health risk, because you're implying eating "better" is necessary to lose weight, and eating "better" almost
always puts "better" out of reach of low-income families. "Yes, you can lose weight, you just need to spend $60 more a week on things I consider better at the grocery store."
Better is a relative term. Your better is not my better. How do you quantify better? Can you explain that to me?
Eat fewer calories than you need. Lose weight. Not rocket science. Sweat the other stuff later, and treat it like a separate issue, because it is.
Wouldn't disagree so strongly with you if you said "this is good. In addition to just figuring calories out, people should also eat better." Then I'd agree with you, but you're indignant and "amazed" like nobody understands the nuances of one value minus another, and if you're not making a salad, why even try. My entire life I've been overweight, and everybody has told me I need to eat "better," and I just started eating less of exactly what I ate before and it works. It's mysterious.
