Jenna Dewan Tatum Hollywood salad

Jenna Dewan and Channing Tatum welcomed daughter Everly back in June, and since then the 33-year-old actress has lost a whopping 33 pounds. When we caught her out and about in Los Angeles on Monday, she showed off her amazing figure in a tank top and a pair of leggings. So we're dying to know ... what's her secret to looking so fab?

Earlier this month Jenna told Us Weekly that a vegan diet and intense 90-minute workouts are what helped her shed the weight ... and keep it off. "The second I found out I was pregnant, I called [my trainer] Jen Johnson," Dewan said. "We found areas we wanted to target: arms and legs. I wanted to keep the muscles alive. Working out kept me sane. I would feel a burst of energy and all my hormones would regulate."

Dewan has reportedly been a vegetarian since she was 13 ... guess that explains the salad she's hanging on to! Jenna's daily diet includes fresh vegetables, oatmeal, salads with chopped-up veggie burger and vegan enchiladas. Jenna works out four days a week with her trainer for 90 minutes a pop, and also does cardio dance workouts, hiking and strength-training on her own.

Dewan added, "I stayed in shape [throughout my pregnancy]," she said. "I was working out almost every single day or walking or hiking ... I think a lot of women find out they're pregnant and are like, 'Let's go crazy and eat ice cream every day!' To me, it was, 'I'm growing a human being, and I want to give this little soul the best nutrition I can.'"
