1. Intermittent Fasting

Williams is a fan of intermittent fasting, also known as time-restricted eating. “Can intermittent fasting improve your health? Losing weight and being physically active help lower your risk of obesity-related diseases, such as diabetes, sleep apnea and some types of cancer,” says Manpreet Mundi, MD. “For these diseases, intermittent fasting seems to be about as beneficial as any other type of diet that reduces overall calories.”

2. Balanced Diet

Williams enjoys a mostly plant-based diet but allows herself indulgences now and then. "For my diet, I really am not on anything strict to be honest,” she says. “I just do what makes sense. If I’m craving a hamburger, I’ll have a hamburger. But then the next day I’ll make sure that I have a salad, a lot of water, and a good mix of vegetables. Same goes for something like pizza, if I want it I’ll have it, but then the next day I’ll make sure it is filled with healthy habits."

3. Treadmill In the Bedroom

Williams keeps a treadmill in her bedroom to encourage working out first thing. "Individuals can burn around 600 to 800 calories in an hour with a treadmill versus about 400 to 500 calories in an hour on a bike,” says Jessica Mazzucco, a New York City-area certified fitness trainer and founder of The Glute Recruit. “But that's with the big caveat that calorie burn rates vary greatly depending on your age, genetics, weight, gender and other factors."

4. She Loves Boxing

Williams is a huge fan of boxing workouts. “Boxing requires the full body to move,” says trainer Anthony Char. “From staying on your toes to engaging the core muscles or throwing a jab or a cross, there’s a lot to think about, which makes it great for training both the mind and body. It’s also a great calorie burner and can often burn more calories than cardio workouts such as running. It’s a fun alternative to traditional cardio workouts like HIIT or swimming.”

5. Inspired By Motherhood

Williams says having her daughter Pilar Jhena McKinley in 2019 inspired her to take her health seriously. “When I had PJ, it was like a switch flipped,” she says. “I had her late in life, and I know that I want to do everything I can to keep up with her. I equated being healthy to feeling great with her, both mentally and physically. That meant making the right fitness and diet choices all the time. My healthy lifestyle is now fuelled by the intention of having the most energy I can to keep up with her and to make sure I’m blessed to be here with her as long as I can. She is my driving force, and regardless of my schedule which is just as crazy as ever, I’ve made it a priority to stay healthy for her.”
