What Clients Are Saying

After suffering for decades with worsening stomach disorders (gas, bloating, diarrhea, and cramps), I made an appointment with Isabel. My symptoms dramatically improved within four days of speaking to Isabel and following her recommendations. I have continued to improve and can now eat foods that I never thought possible, and I feel incredible. Isabel is a brilliant nutritional detective who has turned my life around.

- Suzanne

You {Isabel} have been a life saver. I want to let you know how much I appreciate all you’ve done for me. You’ve been a light and a huge support through my whole pregnancy. You gave me the feeling of control when I felt very out of control. I can’t thank you enough.

- Lisa

Working with Isabel is both effective and fun, and her knowledge of nutrition and exercise enable her to adapt to each clients needs. She is an excellent listener and is able to realistically influence and help me to alter my lifestyle habits. I am proud to say I have lost 30lbs with her guidance.

– Calla

Isabel has helped me put many aspects of my health into perspective, and use the right approach when I wasn’t sure how. Isabel has helped maintain and lower my blood pressure and cholesterol through positive eating habits, supplements, and workout routines.

- Michael

I first met Isabel at a presentation and was so impressed with her message that I decided to see what she could do for me. Approximately eight weeks after starting with Isabel, I was down about 10 pounds, and over the past few years, I have been able to keep the weight off and even lose a few more pounds. I would highly recommend anyone to hire and follow Isabel’s easy recipe to getting back to or for starting a healthy lifestyle.

- David

Working with Isabel has helped me to rethink the way I look at food. She has helped me to let go of dieting and has taught me to feel good about what I eat. Because of Isabel, I am proud to say that I am no longer on a diet, and instead enjoy my new approach of living a healthy lifestyle. As a result I’ve surpassed my 15 lbs. weight loss goal and am down 25 lbs.!

- Bob

Thanks to Isabel working with me to help me make better choices with nutrition, I feel so much better! She has helped my transition to healthier eating in a way that was very natural and intuitive. I really enjoy her style and her genuine desire to help. Isabel taught this is a way where I don’t have to think about eating better, I just am eating better!

- Peter

Isabel shared the tools and knowledge necessary to achieve my goals of eating healthier and losing weight, and I’m proud to say that over 8 months I’ve lost 25 lbs. She’s incredibly talented at creating a proper plan and providing clear direction along with lots of realistic ideas to ensure success. Her passion for health and fitness is magnetic! Thank you, Isabel!

What makes Isabel Smith Nutrition so successful in helping clients?

We’re holistic in our approach and we work with clients WHOLE lives to help them be successful- including eating, motivation and intuition, behavior change and confidence, exercise, sleep, environmental considerations and more. So when you work with us, you’re not just getting a meal plan, we’re working with each client to improve their LIFE (each client is completely specific, too!) and the way they think about food- it’s not a diet it’s a lifestyle.

What are the eating and wellness philosophies of the practice?

We’re all about the long term here- that’s long term health and quality of life. We don’t promote diets and nothing we do is considered a “diet,” we work with each one of our clients to help them realize their eating habits, and help them to feel empowered to make the choices that are right for THEIR body. We love LOTS of plants, clean protein and organic produce whenever possible- but we realize that’s not the reality for most or even some of the time, that’s why we’re focused on creating for each and every one of our clients individually.

What if clients aren’t in New York City, how do client meetings take place?

We work with clients all over the country and all over the world. We meet with clients via video chat or phone (based on preference and convenience) and in between we email and communicate in the easiest way possible for the client. Truly, it works just as well as in person, maybe even better.

What types of clients does ISN work with?

We work with clients of all types and all ages- men and women, ages 9-94. We work with clients with a number of health issues, including body image and eating disorders, hormonal and thyroid balance, blood sugar and energy, weight loss and intuitive eating, athletic performance (professional athletes), digestive issues, oncology and more.

How long does it take to be successful?

Because everyone is different in their goals and in their journey it varies, certainly clients will be successful in just a few weeks and others need a few months. We recommend budgeting at least 3-6 months for full success (though we have a number of clients who have been working with us for years!).

How do I get started?

Contact us and let us know you’re interested or send us an email: [email protected]. We’ll talk to you about who’s right for you to work with and we’ll set you up to get you started!

How much does it cost?

Fees vary based on the type of package you purchase and your needs. Contact us to receive information on pricing.

Is insurance accepted?

We don’t accept insurance but if you work with Isabel we can provide you with a superbill (medical receipt) upon request. If your insurance plan reimburses for dietitian services you can submit to them and they’ll reimburse you directly. Payment will be due upfront to us before we issue a superbill.

What are the business hours?

They vary from week to week but typically, our hours are Monday through Friday, 10 am to 6 pm EST.

What is the refund policy for products and virtual coaching?

We don’t handle (at this point) shipping of products, so you’ll have to work with the vendor for returning product. We don’t refund for virtual coaching but if you have any issues please contact us! *We also do not refund for 1-1 client coaching.
