Zero Effort Nutrition
Z.E.N. stands for Zero Effort Nutrition. We believe in “Food as Medicine” — that what you eat is the foundation of how you feel, perform, and live. Since 2010, we’ve been preparing fresh, organic, chef-crafted meals and delivering them daily to doorsteps across Southern California.
Z.E.N. is not just another diet meal delivery service. Our in-house team of chefs, nutritionists, and dietitians design every meal to be calorie-controlled, macro-balanced, and genuinely delicious. We source organic, locally-grown ingredients and prepare everything fresh — never frozen, never processed, never pre-packaged.
Our team is comprised of like-minded people, including our experienced staff who have worked with the founders of Z.E.N. in this industry for over 20 years, as well as a network of doctors, dietitians, nutritionists, pro athletes, business execs, gym owners, trainers, and many others. We all share a common goal of promoting clean and healthy eating as one of the most important steps towards better health and lifestyle.

Meet Our Founder
Mariana Rossano
Mariana Rossano is an entrepreneur with 20+ years of experience in the Healthy Food Delivery Business. Her career and compilation of health knowledge began in the personal fitness industry and expanded into a consultant position at the famed Zone Gourmet in New York during its infancy stage. The instinctive marketing acumen of Ms. Rossano contributed to the organization’s rapid growth and overwhelming success, positioning her to open and head Zone Gourmet in Los Angeles as the region’s Chief Operating Officer.
As COO, she oversaw all facets of business operations including managing a staff of 130 employees. She then went on to create Fresh Dining as Co-Founder and President, before founding Z.E.N. Foods — bringing not only her invaluable experience but a knowledgeable staff and a huge following of loyal clientele. Her network includes physicians, dieticians, nutritionists, athletes, agents, entertainers, and personal trainers who continue to contribute to her ongoing success.
“Good food should never be complicated. We cook it fresh, we deliver it daily, and we make sure every bite is worth it. That’s the Z.E.N. way.”
— Mariana Rossano
