Boost physical activity

In The Glycemic Index, Simpler, Sally Squires notes,

In China, where white rice is a staple, rates of obesity and diabetes have been relatively low until recently. Not only is a more Western diet creeping into the country, but physical activity is declining. The glycemic index "probably doesn't matter at all, provided that you keep your body mass index under 23," Jenkins said. "If you stay skinny and physically active, you don't have to worry about all this nonsense."

As Inas Rashad and Michael Grossman argued, people are better off when they're poor. So which presidential candidate will impoverish us?
