INTERESTING TIMES

A study showed that engaged women want to lose on average 20 pounds to look great on the big day. A doc in Florida is offering the Ketogenic Enteral Diet (K-E diet) for ladies wishing to slim down before their nuptials. The diet lasts 10 days, costs $1.5K, and causes approximately a 10lb weight loss. The ketosis is monitored using ketostix which are widely available for diabetics. The dieting ladies are permitted nothing caloric by mouth. Great idea? Not so fast. It's not that hard to eat a calorie-restricted ketogenic diet without paying $1.5K and having a tube up your nose. Think about it.
