what you said is a lie gurus like me tell children like @jack because we don't want to confuse them with complex reality

the reason low-carb diets work is because all processed foods contain carbs, so by eliminating carbs you eliminate processed foods

the actual damage in processed foods comes from seed oils, but seed oils are liquid and require starch as a sponge to hold them together - thus creating products like potato chips, french fries, donuts etc

so yes, low-carb diets work, but not for the reasons you think
