She sometimes mixes things up and adds in a couple of SoulCycle classes, and she also goes horseback riding, which is another excellent workout.

Her Workout Principles

Kaley Cuoco's workout principles revolve around her preference for yoga, which she found to be the most appealing among various exercises like running and Pilates.

Despite being a fitness enthusiast, she acknowledges the challenges of maintaining a consistent routine.

“Sometimes do I want to get up in the morning and do it? No, but when I get out, I feel like a million bucks.”

- Kaley Cuoco

However, as she recognizes the changes in her body with age, she has begun paying closer attention to her fitness routine.

Kaley Cuoco’s Diet Plan

Kaley Cuoco maintains a generally clean diet, keeping an eye on her calorie intake, but occasionally indulges in treats like a grilled sandwich, fries, and a shake from In-N-Out Burger.

Her daily menu typically includes:

  • Breakfast: Apple and peanut butter on toast or oats with fruits and skimmed milk
  • Lunch: A vegetarian Subway sandwich with onions and jalapenos
  • Dinner: Fish and vegetables

Kaley frequently includes vegetables, fruits, peanut butter, cheese, bread, tofu, apples, and fish in her diet.

“As I’ve gotten older, I’ve had to change my food intake,” the actress explains. “My husband, Ryan, eats so much. When we first got married, it was so much fun to eat like him. We got into this habit we called the bedtime snack. The drawers next to the bed were filled with candy. Eventually, I realized it was mindless eating. I was just doing it because he was doing it, and it was adding hundreds of calories I didn’t even think about. So I cut that out.”

- Kaley Cuoco

Diet and Nutrition Principles

Kaley Cuoco adheres to a diet primarily consisting of whole, natural, and healthy foods, with a focus on portion control. As a pescatarian, she avoids meat but includes fish occasionally.

To maintain dietary discipline, Kaley eliminated tempting items like soda, sugary cereal, and chips from her cabinets.

“I have to have a cheat day. I know when I’m being good all week long that come Sunday, I’m going to lie by the pool, have a drink, and eat some pizza. Then I wake up on Monday morning and I’m all ready to start the week again. I’m just going to be in a bad mood all the time if there’s no light at the end of the tunnel.”

- Kaley Cuoco

While she doesn't shy away from carbs, she aims to consume them earlier in the day, and aside from fish, she abstains from animal proteins.

What Supplements Does She Take?

Kaley Cuoco incorporates various supplements into her workout routine:

Research from the National Institute of Health indicates that BCAAs can contribute to decreasing muscle soreness, resulting from micro-tears caused by physical activity [1].

As a fitness trainer, I often recommend such supplements to my clients, as they can significantly beneficial for building lean muscle mass, minimizing exercise fatigue, and preventing muscle waste.
