The problem is, it's based on this half-truth: Americans eat too many simple carbs, so if you eat fewer, you'll lose weight, and even more weight if you eat whole foods and less fat, and you'll enhance your health rather than harming it.
som er at amerikanerne spiser for mange simple kulhydrater, så hvis man spiser færre simple kulhydrater vil man tabe sig. Man vil tabe sig endnu mere hvis man spiser fuldskornsmad og mindre fedt, og man vil forbedre ens helbred i stedet for at skade det.
