I always say that my mother should be the poster child for NEAT. She's under 5' tall, maintains at about 120 pounds. What she eats at the kitchen table runs about 1800-2000 calories. I know because I worked out her breakfast/lunch for her once and it's pretty much the same daily (~1200 cals I think). Our dinners run 600 to 800 calories so that's where I get the total. That doesn't include the candy that she buys during her weekly trip to the 'bakery'. It's a specialty shop that sells tons of stuff and each week she'll come home with probably 2 or 3 of the family size chocolate bars and pretty much the same of some kind of candy/toffee. Out of deference to me not eating this kind of stuff she tries sneaking it in.
In the winter, maybe, she'll use the treadmill twice week for 30 mins. Other than that it's just her usually moving around stuff. She's very (to be nice) inefficient when doing things, which probably helps.
