Florencia takes natural appetite suppressing supplements. "You already know IP2 from my Doc @csciales? 🙌🏻 It's a natural enzyme extracted from a type of 'papa' called IP2 that manages to naturally increase an amino acid produced by the gut that lowers appetite, giving the message to the brain of being satiated deadline," she wrote in a post, claiming it helps decrease food intake and late night binge eating.  

Florencia encourages a healthy lifestyle, with a combination of diet and exercise. "The important thing: take care of our body in a healthy way, eating healthy and doing physical activity," she said in one of her Instagram posts.

Florencia spends a lot of time working out. She usually prefers strength training. "Physical activity is anything that gets your body moving. Each week adults need 150 minutes of moderate-intensity physical activity and 2 days of muscle-strengthening activity, according to the current Physical Activity Guidelines for Americans. "Half way through and trained hard," she captioned a video from one of her workouts.

When it comes time to enjoy wine, Florencia opts for red over white. "Red wine, in moderation, has long been thought of as heart healthy," explains the Mayo Clinic. "The alcohol and certain substances in red wine called antioxidants may help prevent coronary artery disease, the condition that leads to heart attacks."

Florencia also enjoys boxing for fitness. "Which One Should I Hit Harder? 😂 😜 Take Rock, take," she captioned a photo from a session. Boxing is a great workout "because it constantly requires you to think, change your position, and change your posture," physical therapist Linda Arslanian, director of rehabilitation services at Harvard-affiliated Brigham and Women's hospital tells Harvard Health."You're swinging your arms, moving the muscles of your arms and shoulders, increasing your upper-body strength. And when you're in the boxer crouch with a wide stance, with your knees slightly bent, you're strengthening your core muscles, back, and legs."
