I had the pleasure to meet and get to know Marjan. She's knowledgeable and truly passionate about helping people get to their best self. Never judgmental! There were many days I struggle with my journey of weight loss but she was extremely patient, encouraging and always cheering me on!! She's someone that even after my programs ends, I would want to still keep in touch with and let her know how my journey is going.
She's truly wonderful!!

I did a lot of research to find a nutritionist for my child and got to the point that there is no one in OC who has more positive reviews than Marjan with Let's Nutrition.
The reviews were amazing, and after a consultation I knew it was time to give it a try. During our program, Marjan was amazingly kid friendly, knowledgeable and understood my concern that I didn’t want to introduce my child to “ A Diet” or lower down her self-confidence. My daughter needed a program to get all nutrition she needed and meanwhile shed some weight. Marjan Constantly texted us with different recipes and introduced

I found Let's nutrition/Marjan through yelp after reading lots of positive reviews and seeing progress photos of her clients. 10 months back, I went to Marjan with the hope of losing weight with limited knowledge. I have lost 20 lbs and continue to lose more. Signing up for her program was the best decision I ever made.

Marjan is very knowledgeable and skilled person at what she does! She is the most motivated, kind and helpful person I have ever met. She is just text message away when you need her during the program. She taught me how to get back on the track whenever I fell off the track

Signing up with Let's Nutrition/Marjan has been one of the best life decisions I've ever made for myself. I've already been leading a healthy and active lifestyle, but yet I was struggling to meet my weight and body fat percentage goals. I've tried all sorts of gyms, personal trainers and even delivery meal plans...all great things, yet STILL not seeing the changes I was looking and working for. I decided to try one more thing before giving up with trying....educating myself on nutrition.
Reading all these positive reviews, I had to schedule a meeting with this famous Marjan. And sure enough,

Like you, I was checking out nutrition programs, exercise programs, and gyms/boot camps on Yelp. I have paid thousands of dollars in different doctor's offices and their recommended nutrition programs and coaches and never lost any weight. In fact, they told me they were baffled that I was gaining weight through their program, which was frozen meals and powdered drinks.

Right off the bat, after meeting with Marjan I knew this was different. When you sign up with her, you are signing up for a personal coach and motivator. You have her number and she personally checks up on you multiple times

I had the pleasure of getting to know Marjan as well as being able to work for Marjan. I definitely have to say when meeting Marjan there was never any judgment. Marjan has shown me many different skills and knowledge to keep a healthy life style. As she knows me very well, I have struggle truly with controlling my weight and every time I have come back she is always there to give guidance and support and reassure me that its okay to start all over again.

Marjan is the best at what she does! She is the most kindest, sweetest, motivating, helping person I have ever met and she will definitely

Contacting Let's Nutrition has proven to be one of the best decisions of my life. During quarantine, my activity level went from "low" to "extremely sedentary". Layer a poor diet of comfort food on top of that, and it was a recipe for growth - the unhealthy kind. I was definitely headed for the kind of weight gain that might be nearly impossible to shed. Thank goodness Marjan was able to turn me around. She is extremely knowledgeable, professional, and supportive. She knows exactly how to motivate and keep me engaged, even when I feel like I've fallen off the wagon

I had the pleasure of meeting Marjan this summer when I contacted her for nutrition and weight loss counseling. Throughout my lifetime, I have tried many different ways to lose weight and have always failed. With Let's Nutrition program I learned how to understand the food I eat and how my body works with this food. Marjan taught me which foods encourage a healthier lifestyle and healthier living. The best part of this program is that you don't have to restrict yourself and can continue eating the food you enjoy but in moderation. The key to success is the constant communication on a daily basis

I have had the pleasure of being a "Let's Nutrition" client for about 3 months. Marjan has shown to be a skillful, caring, knowledgeable, and motivating nutritionist.
She helped me to meet my goal and motivated me to change how I view food and make better choices. She has helped me modify my habits to achieve a healthier way to approach eating.
I lowered my blood sugar and that was my main goal and I lost about 23lbs in 3 months with her help.
She has been always available to answer my questions. She shows

I've been with Marjan for two months and have signed up for the 9 month plan with 3 months of maintenance. I need to lose a lot of weight and headed into my 40s. So far, I have reached close to a 20 lb weight loss in just 2 months. I have tried all types of diets ranging from keto, paleo, HCG--you name it, I likely tried it. The problem with the past diets was that I had a terrible time maintaining the weight loss and it wrecked havoc on my metabolism and mindset.

What Marjan teaches you is to change your outlook and relationship with food. She doesn't restrict you from eating things

The greatest source for nutrition support!

I came to Marjan wanting to overcome crazy sugar cravings, and left feeling so much better! The supplements and constant support from Marjan made all the difference in not only kicking my sugar cravings but also improving overall health and wellness.

Highly recommend!!!

Marjan changed my life. I have been struggling since turning 40 to lose the extra weight on my petite frame. I came to let’s nutrition at my wits end. I tried optavia, ww, Noom, low carb etc. I would lose maximum 5lbs. As a physician, I understand how to lose weight. I just couldn’t get there. I didn’t have a lot of weight to lose , but I couldn’t get the scale to budge. After reading reviews online, I made and appointment with Marjan. I signed up on the spot. The weight came off. No tricks, gimmicks, or starvation. I was motivated, encouraged and held accountable. I continue to work with

5-star business run by a caring and knowledgeable nutritionist!

Go ahead and scroll through all the reviews and don't be surprised by the consistent 5-stars. Marjan knows what she is doing and you are in excellent hands!

I gained a lot of weight during and after my pregnancy. I have to be honest I enjoyed food a little too much while pregnant and during COVID... so at some point enough is enough.

I had tried on my own for so many years, but lacked the consistency and actually the education of nutrition to losing weight.

Marjan will guide you through it. Lots of information at first, but

Marjan is the best at what she does. Knowledgeable, attentive, extremely empathetic, and a great motivator, she helped me completely rethink what good nutrition and a healthy lifestyle can look like. She guided me on a journey I had been struggling for years, losing the slow buildup of weight I gained since I was in high school and I'm just getting started. I'm so glad I took that first step and reached out to Marjan for help, and I hope whoever is reading this will take that first step too. You won't regret it!

This review is long overdue. If you need someone to help you loose weight, look no further and contact Marjan.
I hit my heaviest weight on August 2020 at 200 Lbs ( BMI 37) due Pregnancy related weight gain and busy lifestyle. I was diagnosed with sleep apnea at the age of of 34. I knew I had to make some changes in my life or soon I will have obesity/sleep apnea related health issues such as diabetes,hypertension,etc at such a young age.
I am gald I found Marjan on Yelp and she changed my life. She deeply cares about her clients and provides the best guidance. I learned how to change my lifestyle

Marjan is the best nutritionist I've ever worked with. She provides all the necessary resources for one not only to lose weight, but to learn how to live a healthier lifestyle while doing so. The process is so motivating and having 24/7 support is wonderful. I could've never gotten my health back if it wasn't for Let's Nutrition, I'm so thankful! If you're on the fence about this decision, don't hesitate to make an appointment because you definitely won't regret it! :)

Though I've tried a plethora of weight loss programs (UCI-HMR, camp transformation center, medifast to name a few), a nutritionist is something that was not on my radar until I saw a friend of mine who posted about her weight loss transformation and I decided to reach out to her and get more info. It was one line that she said that sold me: "I lost 30 lbs and I know I won't gain the weight back since now I know how to keep it off." What a concept, losing weight and keeping it off! I had been a dieter for the better part of the last 10 years and it wasn't until I started

Where do I even begin? Ever since having my three babies (especially my third) I've struggled loosing the last 20 pounds. I have tried doing everything from Weight Watchers to Jenny Craig and nothing seemed to work. My desperation of feeling comfortable in my own skin led me to searching on Yelp and this is where I found Marjan.

Marjan has been a godsend. What she does offer is a WEALTH of information. She has meal plans and recipes, and supplements, motivation, and so much more. And most importantly, she makes you ACCOUNTABLE. I think thats the hardest thing, staying accountable and staying

Marjan has made a positive impact on helping me with nutrition. In fact, she got me focusing on my nutritional needs. She sets up nutrition goals to achieve and offers in-person check-in per two weeks. The check-in kept me motivated and able to understand the changes I needed to make to meet my goal of losing weight. I really enjoyed learning new ways to improve my diet! Marjan was never critical if I had a bad week and always had positive things to say to get me to focus on the next week. Moreover, any questions I may have, I can message her and get guidance quickly. She helped me lose 10 pounds

I first heard about Marjan from a coworker a couple of years ago who lost over 60 lbs on her program. I was so inspired by his weight loss journey and wanted to try the program he did but was too scared to "give up" the foods I loved. I finally signed up and started in January.

This isn't just a diet program Marjan offers, it's a lifestyle change. Marjan is always available to guide, support, encourage, and be my coach. Her program makes the weight loss goal feel obtainable and exciting!

I lost 16 lbs in the first two months and have ten more lbs to go to meet my goal

Since I began working with Marjan I've lost 45+ lbs and counting.

I can tell you she doesn't have a magical formula, and you will still have to work hard to keep your nutrition in check; however, the support system and accountability she offers make a big difference in the journey.

Many of us understand the basic principles needed to lose weight, but we need that little push to get us over the mental road block. Marjan adapts to each of her clients to support their individual needs and provides that edge some of us need to make it to the finish line.

Let me begin by saying I LOVE LETS NUTRITION, and I LOVE MARJAN even more! Over the last few years, I had put on 20lb of weight, and although I was eating healthy, I just couldn't seem to get the weight off. Then I met Marjan, who was so confident that she could get me to lose my weight. She reviewed my diet and pointed out what I was doing wrong. Firstly, Marjan doesn't give you a diet plan; she gives you a well-rounded nutrition plan that you can carry for the rest of your life. Her approach is so personalized, and she walks with you every step of the way. She motivates you, guides you, and yes
