"I have really benefited from having my DNA tested with Kate and benefiting from her expertise - if only I had had this during my playing days.

Achieve Your Goals

Supporting Your Success

Food should taste good, but it should also nurture your body. Since 2000, I have been providing clients with a variety of weight management and nutrition services. With a creative, dynamic, and responsible approach to healthy eating, as well as an extensive range of industry experience, I have helped hundreds of clients achieve all their nutrition goals, with my healthy and sustainable approach.

Weight Management

Reach your optimal weight and health

Kick start your weight loss journey today.

Whatever your current diet is, I will evaluate your history, lifestyle, dietary habits, functional lab tests (if together we deem this necessary), and create a personalised Weight Loss plan (12 week-meal plan and recipes) based on your specific needs. 

We will meet every 2-4 weeks to measure your achievements, and fine-tune certain elements as your goal weight.

If you can't come to my London, Harley St or Bath clinic, I am able to offer you a phone or Skype consultation.

Sports Nutrition

Superior, personalised sports nutrition

Sports Nutrition can be one of the keys to a happier, healthier life. I have worked with international sports teams, British athletes and sports individuals, including the "fastest man in world rugby " - Carlin Isles.

I offer strategic tools and techniques to help clients achieve a more balanced and fulfilling lifestyle. After several personalised sessions, you’ll become well-versed at making the best food-related decisions for your health and training needs.
