Kourtney Kardashian weight-loss secret after giving birth Kourtney Kardashian showing off her amazing bikini abs.

On her weight-loss secret after giving birth to son Mason:
 "Because I'm nursing, I have to eat constantly. So when we're filming I tell everyone, 'Remind me that I'm hungry.' And if it's a snack, I try to make healthier choices."

On her diet vices:
 "I'll eat Oreo Double Stufs, but I'll have two instead of eating a box of them. And I love chips! I like Sour Cream & Onion Ruffles and [my boyfriend] Scott always buys me the mini Hostess Donettes because I'm obsessed with them."

On slimming-down tips:
 "Little meals throughout the day are realistic for people to follow. Try to get workouts in. It's always so hard to start [a weight-loss plan] and get into it, but I think it's a positive thing that everyone should try to do for themselves."
