We’re always talking about food here at Back Talk, so this week we look at the side of grub we don’t always love to think about — nutrition. We chose the day preceding The Biggest Loser casting call at Methodist Medical Center in Oak Cliff, to go out and speak to one of the hospital staff nutritionists, a Lake Highlands resident who also happens to be related to one of the Advocate editors. She offers us some good tips for preparing for swimsuit season and general health, and talks about some of her favorite neighborhood eats.
