Looking for a weight loss dietitian or weight loss nutritionist in London? If you are trying to lose weight, working with a registered dietitian or nutritionist is the most effective and medically sound approach. They provide not only a personalised meal plan, but ongoing support, results monitoring, realistic goal-setting, and the accountability that is essential for long-term weight loss success.

People who work with a weight loss nutritionist or dietitian don't just benefit from professional expertise — they gain a dedicated partner who adjusts their plan as they progress, troubleshoots plateaus, and keeps them motivated throughout the journey.

Why Work With a Weight Loss Dietitian?

Fad diets and generic meal plans fail because they ignore your individual metabolism, health history, lifestyle, and food preferences. A registered dietitian offers something different: a genuinely personalised strategy based on clinical assessment and the latest nutritional science.

At Raquel Britzke Clinic, our approach is built around fat loss while maintaining muscle mass — the only sustainable form of weight loss. We do not use meal replacements, calorie-counting apps, or restrictive fad diets. Instead, we create a plan around real food that fits your life.

Our Weight Loss Method

Our unique method has helped over 20,000 patients worldwide achieve lasting weight loss results. The process begins with a comprehensive consultation including a full body composition analysis using the Tanita MC-780U bioimpedance scale — measuring body fat percentage, muscle mass, visceral fat, metabolic rate, and more. This data drives every decision in your personalised plan.

We also offer optional DNA diet testing and food intolerance testing (200 food types) to further customise your nutrition plan around your unique genetic profile and digestive sensitivities.
