This is interesting, however. Let's think about it for a minute.
- Caloric restriction has been shown to work. Caloric
restriction would most likely result in individuals
being at least slightly underweight.
- Underweight have higher mortality in the old age.
Mildly overweight need not worry.
Fair enough. I personally wouldn't even try CR - I don't have enough willpower to be slightly hungry for the rest of my life. I'm trying to incorporate some Intermittent Fasting in my life though, since it has some similar benefits.
Caloric restriction requires you to eat food that is denser in nutrients. Many who don't eat much do so because they're poor and can't afford enough food, let alone food that is denser in nutrients. That is why, on average, those with lower body weights have lower mortality. Those who assiduously follow a CR diet rich in nutrients may live longer, but they must be a tiny slice of the pie.
