I'm a nutritional therapist (CNM London), a functional medicine practitioner (FMU), and a yoga teacher and yogi (YC, BWY). I'm also a fellow student at The American Academy of Anti-Aging Medicine. I have been in clinical practice since 2011 and have extensive experience as a yoga teacher (15 years).

I specialise in weight-loss and in the stress-fatigue-burnout continuum. Both disease stages affected me deeply for more than a decade when I was younger.

I love to work with women in their forties who are currently struggling with these same health issues that I struggled with for so many years in the past. My clients are women in their forties with excess body fat and stubborn weight-loss; poor sleep; low energy levels; poor eating habits; feeling unhealthy and unattractive, and needing to revamp their body, work on their fitness, lose weight, and feel and look sexy again.

I have a genuine passion for coaching, motivating, inspiring, positively challenging, and guiding. I give these brave women a new opportunity to take control of their lives again, to set realistic and achievable goals, and by going through a set of steps daily and weekly together, to ensure that success they dream of but that they simply cannot achieve on their own.

My role as a coach is to help these women understand what the real underlying root-causes of their health problems are so that they can finally gain clarity and understanding of what is causing them to be out of balance in their bodies and in their lives. My role is also, of course, to give them the right tools for them to put an end to the vicious cycle of stress, fatigue, weight-gain, poor self-esteem, depression, lack of faith in the future, etc., and to guide them and support them through the whole process of healing and transformation with a body*mind*soul program that works.

I believe in transformation. I believe that everything is possible.

If you have the right approach, your life can be transformed in unbelieavable ways!

I will help you achieve your weight-loss, wellness, and fitness goals by integrating a set of unique and advanced tools into your personalised program, that include:

Functional Laboratory Testing

To ensure maximum results, I work with functional medicine and functional laboratory tests. It is important to check your levels of various health markers like thyroid, insulin, estrogen, progesterone, testosterone, pancreatic elastase, short chain fatty acids, SigA, inflammatory cytokines, nutrients, genetic and epigenetic abnormalities, cholesterol, triglycerides, cortisol and DHEA hormones, and other, before the start of the program, and at the end, to monitor and view results. I will devise a comprehensive protocol and lifestyle prescription for you and you only, based on your laboratory results, your clinical story, and your symptoms.


Because reversing weight issues, fatigue, burnout, and hormonal dysregulation is a serious thing, you need a professional who can work with you side-by-side, day-in and day-out, for a few months, and deliver to you a complete and thorough program that works for you by tackling your unique individual nutritional requirements and hormonal imbalances. I will be that coach and I will support you every step of the way so that you get clarity about how to achieve your goals and dreams, so that you get the motivation required, the inspiration, and the direction needed. With me as your coach you will not get lost in unnecessary efforts or in strategies that don't work.

Nutrition & Lifestyle

The way to inform a gene, a gland, a neuron, the gut microbes, the cardiovascular cells, and so on, to act in a desired way in order to initiate healing and repair, is done through the action of targeted nutrients. The most potent medicine is the one found in nutrients, in sunlight, in fresh air, in the right exercise routine, and in the right mindset. To lose 10-50 Lbs of body weight, nutrition and lifestyle must be adjusted according to each individual's biochemical needs. This program offers advanced nutritional therapy, meal planning, yoga for weight-loss, yoga for hormonal balance, and functional fitness for weight-loss. You'll be supported, guided, and motivated from the beginning to the end.

Ready to lose 10 - 50 lbs in the next few months? We will make it possible by...

  • Understanding how your hormones are working in your body now and by rebalancing them again
  • Identifying any flaws in your glucose/insulin metabolism and correcting them
  • Fixing your sleep cycle if it is dysrupted
  • Fixing your thyroid if it is dysfunctional (whether or not you're on Thyroxin)
  • Fixing your poor gut function or giving your gut function a boost
  • Stimulating and restoring your lymphatics
  • Devising a diet and lifestyle that are adapted to your individual requirements
  • Correcting your genetic SNPs that promote your disease process
  • Supporting your liver, colon, cardiovascular and other with the right detox program
  • Refining your mindset - retrieving and reactivating the "I can do anything" vibe from your conscious and subconscious minds
  • Toning and invigorating your physical body with yoga and functional fitness

I have created this program out of my own life-long experience with weight-loss, utilizing all the tools that I have acquired in nutritional therapy, functional medicine, and anti-aging medicine.

I only work with a selected handful of clients per month. They get exclusive, personalised, and top-notch coaching, follow-up, yoga and exercise instruction, lab testing, and a lifestyle prescription for a healthy change.

This program offers the four pillars of weight-loss which are:

  1. Spiritual coaching / mindset reset
  2. Vinyasa yoga and Kundalini yoga
  3. Nutritional therapy
  4. Functional lab testing, interpretation of labs, protocols based on results

The program starts by the collection of lab works that include a series of functional markers that are analysed in stool, saliva, urine, and blood. The client receives the kits at home and collects the stool, urine, and saliva on their own. The blood tests require a blood draw at a designated phlebotomist.

While we wait for the results, we start with the mindset, spirituality, coaching, and yoga aspects of the program. We also initiate a detox in preparation for what comes later.

Once the lab results are delivered, I devise a comprehensive and advanced protocol for each client, according to their unique health markers. This happens from month 2. It is then that we start fixing each of the root-causes of weight-gain that they may present with -which are usually all or a good combination of the above.

To ensure results, the ideal number of online classes to do with myself is 2 times per week. Whether you are based in the UK, in America, or elsewhere, there will be a daily yoga class to do with myself online. You will have the option of doing either a replay or a live class. If you live in the radius that I can cover physically, the classes can be delivered in person, at the comfort of your own home. You will have the option of doing 4 or 3 classes per week.

I teach a variety of classes, ranging from Vinyasa yoga and Kundalini yoga to functional fitness with dumbbells, stretch bands, and other easy equipment to maximize time and effort.
