On Tuesday night, the sisters had dinner at La Scala, where Kim said her 16-year-old sister was "trying to make me eat carbs!"
Carbs are a big no-no at the moment for Kim, who tweeted just hours before hitting up the Italian restaurant in Beverly Hills for dinner, "Starting diet TODAY! No carbs. Crazy workouts. Who's with me?"
Apparently Kylie's not on board with this weight loss plan!! And while Kim, 33, looks pretty amazing to us, she's determined to get back into tip-top shape—"No more excuses."
"I'm not gonna call it baby weight bc that's an excuse," she tweeted. "I just gained weight & that's it. Why is it so much harder to lose after baby though!""
She has a theory, too, on why slimming down can be particularly tough for new moms. "I think after having a baby u get so excited u lost a lot of weight," she explained, "then u get comfortable & eat how you used [to] & it creeps back up."
Oh, doll, you look great! Besides, between all those trips to the gym and running after 1-year-old Nori, she's totally allowed to splurge on a bowl of pasta every now and again!
