Actress Halle Berry has a hot bikini body at age 52, thanks to a low-carb ketogenic diet and daily exercise that includes yoga workouts, martial arts, calisthenics, and boxing.
Berry's fitness trainer, Peter Lee Thomas, said the brunette beauty is in such great shape because she has the mindset of a professional athlete.
"I had no idea what her age was when I met her," Thomas told People. "When I found out, I was absolutely shell-shocked because she has the discipline and athleticism of a 25-year-old."
Berry, who was diagnosed with type 1 diabetes when she was 19, follows the ketogenic diet. That's a low-carb, high-fat, moderate-protein eating plan that restricts carbohydrates and emphasizes unprocessed saturated fats such as butter and olive oil, as well as high-quality proteins like salmon, eggs, pasture-raised beef, and chicken.
