Discover how Karla “Coach Karli” De Epstein of Macrofit by PeruvianPrincessFit helps clients lose weight, transform their bodies, and embrace flexible dieting with personalized programs.
When Karla “Coach Karli” De Epstein hit her 40s, most women would have been satisfied with balancing the demands of motherhood and a career. But Karla was on a mission. After two children and years of trying to make every fad diet work, she decided to take control. She transformed her own body, achieved bodybuilding success, and built a thriving business to help others do the same. Her story is one of grit, passion, and an unshakable belief that the best way to lose weight is not through restrictive diets, but through a flexible, sustainable approach to nutrition. This isn’t just another weight-loss story,it’s one of empowerment and transformation.
The Journey Begins: A Mission to Help Others
Karla’s journey toward becoming a macro coach and the founder of Macrofit by PeruvianPrincessFit wasn’t just about her own transformation. It was about helping others achieve their personal fitness goals in a way that was realistic, sustainable, and,most importantly,enjoyable.
By age 40, Karla had tried every diet under the sun, but none seemed to stick long-term. That’s when she found the science-backed approach of flexible dieting and macro coaching. Karla was determined to not only lose weight but also feel healthy, strong, and capable at every stage of her life.
The results were astounding. She dropped the extra pounds, built muscle, and even went on to compete in multiple bodybuilding shows. She didn’t just stop there. Karla took her passion and qualifications, including a Master’s in Science and a certification as a macro coach, and built Macrofit by PeruvianPrincessFit to help others achieve their fitness goals without the misery of restrictive diets.
Breaking Free from Traditional Dieting
When Karla first began her bodybuilding journey, she was faced with the same roadblocks that many others encounter. There was a prevailing belief in the fitness world that extreme diets and hours spent in the gym were the only paths to success. But Karla quickly realized that the more she restricted herself, the more her body fought back. She wasn’t just trying to lose weight,she was trying to build a sustainable lifestyle that allowed her to enjoy food, spend time with her family, and still achieve her goals.
Karla knew there had to be a better way. The turning point came when she embraced flexible dieting,a method that focused on tracking macronutrients rather than cutting out entire food groups. This approach allowed Karla to enjoy the foods she loved while still making progress toward her fitness goals.
It wasn’t just about weight loss; it was about body recomposition,losing fat and building muscle. Karla didn’t just stop at transforming herself. She wanted to share this approach with others who were frustrated by the limitations of traditional dieting.
A Bodybuilding Victory and Business Breakthrough
Karla’s breakthrough came when she entered her first bodybuilding show at age 40. It was a challenge, but she was determined. She pushed through the physical and mental barriers, eventually bringing home four medals. But Karla didn’t stop there. She continued to compete, and her hard work paid off when she won 1st place at the “John Kemper Classic.” This victory qualified her for nationals, leading her to one of the most prestigious national shows on the East Coast: the “NPC Universe.”
These accomplishments weren’t just personal milestones,they were proof that her approach worked. She was able to balance motherhood, work, and training while continuing to make impressive progress in her bodybuilding career. This success was the foundation for Macrofit by PeruvianPrincessFit, where she now helps women and men of all ages, shapes, and backgrounds achieve their fitness goals through a flexible, individualized approach.
