I started with Let's Nutrition in September 2025 after trying many diets and exercise programs with no success. I was at my heaviest weight, frustrated, uncomfortable in my clothes, and unhappy with how I looked. I found Marjan on Yelp and wasn't sure what to expect, but I knew I needed a change. Within just one month, I started seeing results. The nutrition plan, calorie deficit approach, the right supplements, and exercise worked. I've lost all the weight I had gained and now I'm focused on maintenance, building muscle, and continuing to lose fat. I'm very satisfied with the results and grateful for this new, sustainable way of managing my health. Thank you, Marjan! read more

Let's Nutrition Weight Loss - Weight Loss Centers Near Me - Newport Beach, California

I had tried hard to lose weight on my own but could never quite get there. With Marjan's guidance, I lost 18 lbs in 4 months and learned so much about nutrition along the way. She gave me excellent meal plans that made it much easier to stay on track as a vegetarian, especially when getting enough protein has always been a challenge for me. Her menus, shopping lists, and quick prep lunch ideas for busy workdays were incredibly helpful and realistic. What I appreciated most was that it wasn't just about losing weight, but also understanding how to maintain it long term. I'm so grateful for her support and would highly recommend her. read more

"Marjan is an incredibly knowledgeable and passionate nutritionist. I've been trying her weight loss supplements for the past few weeks, and I can honestly say I'm impressed with the results. My metabolism feels stronger than ever, I feel lighter overall, my sleep has improved, and I've noticed a reduction in inflammation. On top of that, I'm finally starting to lose the extra, unwanted weight around my midsection. What makes this even more meaningful is that I've never believed in weight loss supplements--and had never tried one before. This completely changed my perspective." read more

I found Let's Nutrition thru Yelp. It had so many good reviews, so I wanted to try it for myself. When I met Marjan, I had a mentality that nothing can help me to lose weight. But she showed me that it can be done with a properly balanced nutritional diet. Marjan is a knowledgeable coach with a good heart. She would get excited on the weeks that I lost several pounds and she was encouraging if I wasn't losing any weight. I sincerely recommend this program to the people that are struggling to lose weight. I am very happy with my results. Thank you Marjan for your patience and guidance. read more

Great nutrition coaching targeting healthy food choices and portion control. No time consuming meal prep or "program meal purchase plans". Highly recommend ithis system. read more

Before I met Marjan, I was stuck believing everything I read on the internet. I experimented on myself with carnivore, keto, fruits and meat, you name it. When my mom passed away, I gained even more weight, and for a while I convinced myself it was all grief, cortisol, or being stuck in fight-or-flight. On top of that, I was training crazy amounts. BJJ three times a week and sculpt classes in between but I still wasn't seeing results. The truth was simpler: I just wasn't eating right. I had doubts at first because I'd worked with another nutritionist who ran blood tests and made everything so complicated. When I asked Marjan about it, her reasoning was simple and clear and that's the key. At the end of the day, it comes down to a calorie deficit. The supplements keep you consistent, create a daily ritual, and that's why it works. In two months, I've lost 10 lbs. I have a small frame, so weight gain shows quickly but the results here weren't drastic. They came little by little, and that's exactly why they feel sustainable. I never had to cut out foods I learned portion control, and with the supplements, I stayed on track. The health changes went beyond the scale. I've always had unbearable period cramps, and for the first time I had a cycle with zero pain. That was the proof this was working from the inside out. Marjan is more than a nutritionist - she's a coach, a guide, and a living example of her own philosophy. Every time I walk into her office, I see her radiance and poise, and it reinforces that her habits create real results. She's warm, supportive, and genuinely invested in your success. This is an investment, but it's worth it. Marjan will put you on the right track, give you the right tools, and show you that real change is possible. I highly recommend her if you're ready to make a change that lasts. read more

After years of trying to shed my Covid weight, I finally accomplished that with the help of Marjan and her expertise! She lays everything out so well and is such a sweet genuine person. I couldn't be more thankful that she got me to my goal weight and helped me feel my best for my wedding. Thank you Marjan! read more

I am writing a well past due review, with such a deep gratitude for Marjan and all she does to make individual's life change for better. I consider my family's diet a very healthy diet, gluten free, organic, no junk food to name a few. However my younger child had excessive weight that was increasing and concerning to say the least. I was searching for a very long time and with much hesitation I made an introductory appointment to learn more about what services were being provided. With no hesitation afterward we started a program under Marjan's care and guidance. To my own surprise and disbelief in such a short amount of time my teenage child lost total of over 30 pounds - for a child who has carried about 100 pound of extra weight it has been a miracle. Not only all his doctors have been at awe and have asked about the nutritionist behind the scene of these changes, but also it is impossible to go to places and those who know us not mention the amazing change and inquire more. I am forever grateful for not only the positive change Marjan has implemented in my child's life but also the learning curve I gained along the way. She not only helps but also educate you on why & how. I am forever in debt of gratitude. read more

I eat healthy and actually enjoy it. . I'm really glad I made the journey and I am forever grateful that Marjan with Lets Nutrition guided me into a new healthier life. Checking up and sending me tips and reminders. As well as shopping lists, recipes. We worked on menus. Calories and Protein intake. Everything to suit me as an individual. We figured out what was good and what was bad. I'm so happy. You will be amazed at the results. The hardest thing is making the first step. read more

Marjan is the real deal. She is knowledgeable, kind and super supportive. She believed in me more than I did and always pushed me even when I thought I was satisfied, she knew deep down that I wanted more. I came to her at a lower point in my life, health wise. I was a year post partum and had recently had back surgery and knew because I could no longer exercise like I was used to, I had to drastically change my eating habits. It truly is all about calorie deficit but she gave me the tools to make that realistic and the accountability to show up. Also Marjan got to become in love with walking and also taking supplements that my body needs. Thank you Marjan for helping me achieve my goals! I lost 15 pounds and now just feel if I ever fall off track I have to tools to get back on. I feel more confident in my food choices and kicked some really bad food habits. read more

I am so thankful that I found this place! I had been struggling to loose weight for a few years. It seemed like no matter what I did for my diet, I just kept putting on the pounds. I was very frustrated and sad that I was having to purchase clothes much larger sizes. I stumbled across Let's Nutrition in September and scheduled my first appointment. The office manager and Marjan are very sweet and responsive. I was able to get my first appointment scheduled quickly. Marjan immediately impressed me with knowledge about diet and nutrition. She assessed me and gave me a concrete plan to loose weight naturally. She recommended a diet and supplements that came with an easy to follow plan. And, anytime I had a question, I just texted and she responded quickly. I lost 6 pounds in the first two weeks!! I couldn't believe it! It was the first time in years that I had lost weight. It's now been 3 months and I've lost almost 16 pounds!! I lost weight during the holidays and didn't gain anything - talk about a Christmas miracle! I am back into my regular clothes (in just 3 month!!!) It feels great to be able to wear them and not be spilling over everywhere in them. I have also learned how to eat healthy so that I still enjoy my food but I'm not overdoing it. Marjan has taught me so much about food and calories and how to make better choices at restaurants. She texts tips each day and is so encouraging. She totally got how I felt and supported me to get here. Marjan is truly amazing and really knows how to help people loose weight.
