We Anglophones have reasons for adopting strange diets. Increasingly, we live alone. We have an unprecedented choice of foods, and we're not sure what's in them or whether they're good for us. And we expect to customize practically everything: parenting, news, medicines, even our own faces.
The overarching conventional wisdom - what everyone from government experts to my French girlfriends take as articles of faith - is that restrictive diets generally don't make you healthier or slimmer. Instead, it's best to eat a variety of high-quality foods in moderation and pay attention to whether you're hungry.

Ukrainian dads may not change enough diapers, but their government offers paid maternity leave; practically free preschool; and per-baby payments equivalent to eight months of an average salary.
