Kaley Cuoco started struggling with her weight around the third season of The Big Bang Theory in 2010. Fans began noticing a difference in Kaley’s appearance, commenting that she looked heavier than in the first couple seasons of the show.

While some chalked it up to normal fluctuations that many people experience in their 20s, others were more critical and accused Kaley of letting herself go. Kaley later opened up that around season 3 and 4, she started gaining weight and struggled with body image issues as a result.

Some fans speculated that the weight gain was intentional for Kaley’s character Penny, to reflect her beer drinking habits and unhealthy lifestyle. However, Kaley clarified that the weight gain was unintentional and a result of her own personal struggles at the time. She had to learn to ignore hurtful comments and accept herself at any size.

Her Initial Weight Loss Efforts

Kaley first struggled with her weight in her early 20s while filming The Big Bang Theory. Long hours on set meant a lot of takeout and quick snacks between scenes, which led to gradual weight gain over several seasons.

To combat this, Kaley initially tried various fad diets like low carb and Paleo, but found them too restrictive for her lifestyle. She also attempted intense workout programs like CrossFit and bootcamp classes, but struggled to maintain them consistently.

Though she would see some short term results, Kaley had trouble sticking to these extreme plans long term. She realized she needed to find a balanced approach to get lasting results.

In early 2016, after ending her marriage and dealing with some injuries, Kaley realized she needed to fully commit to a major lifestyle overhaul if she wanted to get healthy and in shape. She was tired of yo-yo dieting and seeing only temporary results.

Kaley decided it was time to make meaningful, long-term changes to her eating habits and fitness routine. She committed to cooking more meals at home, swapping out unhealthy ingredients, and working out several times per week with a trainer. Her primary motivations were boosting her energy, feeling confident, and taking control of her health. Kaley was ready to put in the hard work needed to transform her diet, fitness, and lifestyle.

Her New Diet

Kaley started following a cleaner, lower-calorie diet to help lose weight. She cut out junk food and started eating more vegetables, fruits, lean proteins, and healthy fats. Kaley loads up on protein like grilled salmon with veggies at dinnertime. She also enjoys making tacos with salmon and veggies to keep it interesting.

Kaley sticks to around 1500 calories per day, focusing on nutrient-dense foods. A sample day may include oatmeal with fruit for breakfast, a salad with chicken or fish for lunch, hummus and veggies for a snack, and a lean protein with sweet potato and greens for dinner. She emphasizes getting plenty of fiber from whole grains, fruits, veggies and legumes.

Though Kaley eats healthy most of the time, she lets herself indulge in moderation. Having a little dark chocolate or wine is perfectly fine by her! Overall, consistency with her diet along with portion control has been key for maintaining her slimmer figure long-term.

Kaley’s Advice for Others

Tips for Weight Loss

Kaley has shared some helpful tips for losing weight and getting in shape based on what worked for her. One thing she recommends is cutting your portions in half, especially when dining out.

I’ll eat half and then take a little break.” Portion control can be a struggle, but visualizing splitting your plate can help.

Having a consistent routine focused on nutritious fueling and movement has helped her maintain her fit physique.

Lastly, Kaley stresses not being too hard on yourself. Focus on how working out and eating well makes you feel, not just how it makes you look.

Maintaining a positive mindset and not obsessing over your weight is key. “I’m not a fan of beating yourself up,” Kaley told Shape. Finding happiness along your fitness journey is what matters most.
