"The food pyramid was never backed by any high quality evidence"

And yet medical organizations backed government efforts to force it upon our society.

"Calories in calories out is 100% valid for weight loss" "A calorie is just a calorie, so much as color is color."

Yeah, and you can tell an obese person to cut off their legs to lose weight. Sure, you'll be factually accurate, but are you honestly talking about weight loss?

"If you care about overall health then obviously there is a lot more to it than just calories."

Is weight loss without health considerations really the subject you think people discuss when they talk about weight loss? Nobody talking about actual dieting and weight loss is talking about thermodynamics. We're talking about the complex interactions between food, exercise, mental health, and our individual bodies in order to reliably lose weight and be healthier.
