Read on to see 5 ways Southern stays in shape and the photos that prove they work—and to get beach-ready yourself, don't miss these essential 30 Best-Ever Celebrity Bathing Suit Photos!

1. She Loves Healthy Soups

Southern enjoys delicious, healthy soups, especially including almonds, cashews, and split peas. “Being rich in fiber and one of the best plant-based proteins makes peas a satisfying component of a meal,” says registered nutritionist Nicola Shubrook. “They are also a useful vegan source of iron, which is needed for making red blood cells and transporting oxygen around the body. Peas contain heart-friendly minerals including magnesium, potassium and calcium and are also rich in antioxidant nutrients like vitamin C, as well as phytonutrients including carotenoids and flavonols which are heart protective and support cardiovascular function. The soluble fiber peas contain helps us manage cholesterol levels, especially LDL cholesterol.”

2. South Beach Diet

Southern adapted the lower-carb, higher protein South Beach Diet after having her second child. “The fact it’s high protein and basically unlimited veggies always leave me full and not hungry!” she said. “I have lost a total of 18lbs since starting south beach and I am back to my pre-baby weight. I suffered preclampsia which made me gain a lot of water weight and after I sweated and peed it out through the nights and weeks I had 18lbs that would not go away and I tried a lot of diets before I did south beach. It was the only one I saw a difference within one month. And I have a sweet tooth so the snacks they offer are easy, good and help with that!”

3. Acorn Squash

Southern loves making vegetable-heavy recipes such as roasted acorn squash and cauliflower. “Just half a cup of cooked acorn squash contains vitamin A, niacin, folate, thiamine, vitamin B6, and high levels of vitamin C,” say Carrie Lam, MD, and Dorine Lam, RDN, MS, MPH. “As a healthy adult, you can obtain around 20% of your recommended daily allowance (RDA) of vitamin C from acorn squash and this could boost your immune system and skeletal system health and help prevent hypertension, heart disease, cancer, and osteoarthritis.”

Southern enjoys delicious homemade turkey burgers, which are a great source of protein and nutrients. "Turkey is a great source of protein, rich in many vitamins and minerals, and is low-fat – if you don't eat the skin," says Catherine M. Champagne, a professor of nutritional epidemiology and dietary assessment and nutrition counseling at Louisiana State University's Pennington Biomedical Research Center in Baton Rouge. “It's rich in B-complex vitamins niacin, B6 and B12 and the essential nutrient choline.”

5. White Bean Dip

Southern loves healthy snacks like white bean dip, especially when she’s traveling. “Beans and pulses work in partnership with grains to provide a complete protein containing all nine essential amino acids,” says Dr Rupy Aujla. “Lentils and beans (especially soya beans) are also rich in iron, which is ideal if you’re cutting back on meat. Cheap and convenient, beans and pulses contain beneficial fibre, including insoluble fiber which is good for your gut and soluble fiber which helps reduce elevated cholesterol levels and promotes heart health.”
