Working with Alex has been amazing! With her help I’ve lowered my cholesterol 40 points. I appreciate her guidance because it is judgement-free and she helps me adjust my diet so it works for me to lower my cholesterol without feeling hungry. When I realized I was often reaching for a bag of potato chips to snack on in the evenings, Alex helped me choose other foods that still provided that satisfying crunch while being a lot healthier. I would give Alex my highest recommendation!

Alex is that rare thing, a person who is doing what god intended her to do. Her presence in our lives has been a miracle, I am so grateful to her and cannot recommend her highly enough

I can’t recommend Alex Kaplan enough for her exceptional guidance and support. Alex helped me prepare for surgery by creating a thoughtful nutrition plan that optimized my healing process. Her expertise didn’t stop there — she continued working with me afterward, designing meal plans that aligned with my health goals and improved my blood work. When I faced a stubborn case of traveler’s diarrhea while abroad, Alex provided clear, effective advice that helped me recover.. Her personalized approach, deep knowledge, and genuine care have made a remarkable difference in my well-being.

When I first met Alex, I was going through a really rough period in my life. I was overweight and developed vestibular migraines, feeling nauseous with pain in my head and neck all of the time. I had never experienced anything like this before. The medication I was taking made me hungry all of the time. With Alex's help - and some physical therapy - I was able to make good food choices, including the combination of good proteins with healthy fats, low sugar foods without those pesky sugar additives that are bad for you, and learned how to lower my intake of daily grains. Each week, we discuss what I have eaten. With her help, I have learned how to make healthy eating choices, how to choose what to eat when I dine out, and how to eat sweets in moderation. As a result, I have lost 30 pounds. Alex is never judgemental. She is always behind me 100%. She is always there to answer any questions I have. I highly recommend her services for any nutritional needs

I gained a ton of weight during COVID and pregnancy and could not lose it— enter Alex! More than 50lbs later, I’m a different person not only on the scale, but how I think about food. I have learned to eat healthy without feeling like I’m missing out. She is caring, knowledgeable and will make sure you achieve your goals. I’ve worked with other nutritionists and felt anxious on weigh in days, but I’m always comfortable with her because she’s realistic and never judges. She’s the best! I am glad to have her help and guidance!

Alex helped me lose weight almost effortlessly. She helped me become more mindful about my eating and create new habits which ultimately helped me lose lots of weight.

I began nutritional counseling with Alex 6 years ago when I was diagnosed with pre-diabetes and high cholesterol. I decided to work on changing my lifestyle so that I would not wind up on medication. Since then, I have learned so much about nutrition and good food choices. But most importantly I have been able to lower both my A1C and cholesterol with no need for medication! Alex has also taught me a lot about the real science behind healthy food choices. She explains things in simple terms about what to eat and what not to eat in order to avoid glucose spikes and elevated cholesterol levels. I feel I can ask her anything. Some sessions we cover things like how to shop for quality food and how to read and understand nutrition labels. In other sessions I might just need to talk about my food triggers and emotional eating. In these sessions Alex is a great listener and I always come away motivated to get back on track! If you are looking for a well-informed, empathic and motivational nutritionist I would highly recommend Alex Corwin-Kaplan.

I have been working with Alex for almost one year. She is extremely knowledgeable and everything is science and research based. She stays up to date on all the latest information in her field. Although the goal was weight loss, it did not feel like a restrictive diet, it is more a lifestyle change which was super easy to manage. 10/10 recommend working with Alex!

My experience with Alex has been truly amazing. Each week we review what I have eaten and the benefits of each food. She has given me many suggestions and encouragement. This has led to my changing my eating habits, and as a direct result the lowering of my blood pressure and cholesterol level. I would highly recommend Alex to anyone seeking to become slimmer and consequently healthier.

After a year of dealing with gastrointestinal issues, doctors, diets and medication, a past client of Alex Kaplin Corwin recommended that I speak with Alex about nutrition. And so I did! After three or four visits (via Zoom) I feel so much better. I believe I'm well on my way to living a normal life again! I highly recommend Alex, she’s lovely, easy to work with, extremely knowledgeable, and for me a godsend.
