Elle has an inside-out approach to health. "My beauty routine, which is really a wellness routine disguised as a beauty routine, because I truly believe that when you're well within, it shows on your skin," she told Vogue. In the morning she takes a "little swig" of an ION Biome, which she claims is important because "it supports your gut," prepping it for other vitamins and supplements. 

"The first thing I have is hot water and lemon when I wake up, then my Super Elixir greens and a matcha tea. Sometimes I have cap-full of apple cider vinegar in water if I'm feeling like I'm inflamed," she revealed to Harper's Bazaar. 

Hydration is a key part of Elle's health and wellness approach. "I drink three liters of water a day," she told Harper's Bazaar. 

Elle claims that her special water bottle infuses positive energy into her H2O. "I'm gonna fill up my bottle with some water," she revealed to Vogue. "I use a crystal bottle." 

Elle uses a dry body brush for one of her go-to practices. "So for me, circulation is key," Elle revealed to Vogue. "Lymphatic drainage is really, really important. You've got to move those toxins out of your body, it will show on your skin, it will show in the way you feel."

Elle is all about wellness. "I believe in maintenance, I'm not a big binge and purge person," she told Harper's Bazaar. "I think it's really important to maintain wellness year-round. Not because it looks good but it actually feels good – which is really important when you're running a business and you've got kids and a full life. It's easy – I just make good choices and I enjoy the choices that I make." 

"I really enjoy a plant-based diet, I love vegetables," Elle revealed to Harper's Bazaar. "If I'm really in my groove, I love a raw, plant-based diet," she added to New Beauty. "That's how I feel best. I eat grains, nuts, seeds, beans, vegetables, almond milk, hemp milk, chia seeds. I make my own granola in a dehydrator. Avocado, salads, juicing—you know, beautiful, whole, natural foods. As far as animal products are concerned, I'll have a poached egg every now and then, some Parmesan cheese and goat cheese, but they're not staples of my diet."

Elle maintains that making dietary sacrifices can help you slim down fast. "Coming up for summer what I try to cut out is wheat and sugar. If you love bread and butter, that would be what I'd give up for the summer. For me it's a 'fine tune' more than anything else," she told Harper's Bazaar. 

Elle obviously takes her own supplements. She even claims that her Super Elixir green supplements keep sugar cravings at bay. "Since I've been taking the Super Elixir I don't crave sugar anymore and so when I have cheap sugar now I just don't like the taste," she told Harper's Bazaar. "Sugar is addictive but breaking that addiction only takes about three days. Do a week of taking the Super Elixir greens and then try to give up sugar, it's usually pretty successful."

Elle has another method of practicing lymphatic drainage. "I have a steam most nights, and while I'm in the steam, while my body is sweating, I'll put oil on it and then I'll use the body Gua Sha, the same way as I use the lymphatic drainage brush," she told Vogue. 

Elle emphasizes the importance of evolving your routine as you age. "When I turned 50, I started to notice some new changes in my body. I was sugar addicted, sleep deprived, adrenally stressed, and it showed, you know, it showed on my skin, it showed in my body, and I was doing the same things I've been doing since I was 20, and they just weren't working anymore," she told Vogue. "I changed my lifestyle and within a few months, people started to say to me, God, you look amazing, and what are you doing, and I realized there were so many women that must've been struggling like I was and I wanted to share it with other people, so that is the birth of WelleCo."

"I like to be a little bit more rosy and round, because I think at my age, it's just you know, it's more appealing to look less gaunt, so I've noticed that I've put on weight as I've gotten older and that old adage," she explained. "You have to choose between your a** and your face is kind of true [laughs] because if I'm too thin, it really shows in my face, so I keep it round and rosy and fresh."

Elle isn't a big fan of formal exercise. "I do sports like water skiing, running, cycling, swimming laps, snow skiing if it's winter, walking the dogs – I just love to be outdoors," she told Harper's Bazaar. "If I'm lucky enough to be by the sea, I think walking in seawater is one of the best things I can do for my body. It tones the legs and the waist, it's great for minerals, and if you have any water retention, it's a great diuretic. I walk in about thigh-deep or knee-deep water for 40 minutes to an hour," she added to New Beauty.
