Hello, I’m Irma Rendon, a Registered Nutritional Therapist and founder of Effective Nutrition. I help women and busy professionals who struggle with weight gain, low energy, cravings or hormonal changes regain control of their health through personalised nutrition and a Functional Medicine approach. Many of my clients come to me after trying different diets without lasting results. Instead of focusing only on calories, I work on identifying the root causes behind weight gain and metabolic imbalance, such as gut health, hormonal changes, stress and lifestyle habits. My approach combines science-based nutrition with practical lifestyle strategies to help you lose weight, restore energy and improve long-term wellbeing. I trained at the College of Naturopathic Medicine in England, specialising in nutrition, functional medicine and holistic health strategies. Before becoming a Nutritional Therapist, I spent 20 years working in multinational companies. This experience allows me to understand the challenges of maintaining good health while managing demanding careers and busy lifestyles. My goal is to help you create realistic and sustainable habits that support weight loss, better energy and long-term health. You may benefit from working with me if you feel stuck with your weight, struggle with low energy, experience hormonal changes, or want a clear and personalised strategy to improve your health. If you are ready to take a more personalised and sustainable approach to your health, I would be happy to support you. Learn more: www.effectivenutrition.se
Irma is a really good nutritionist. Over the past few months, Irma has taught me a great deal about nutrition and made me realize the problems with my eating habits. With her help, I successfully transitioned from an unbalanced diet to a healthier, more nutritionally balanced one. Many of the recipes she provides are both healthy and delicious, making it easier for me to maintain my current eating habits.

I completed a nutrition program with Dr. Irma Rendon to lose weight in a healthy way and change my eating habits. At the beginning, I thought I was eating well, but I realized that I actually wasn’t.
Her guidance in each session and her support throughout the process of developing healthier lifestyle habits were crucial. I am very happy with the results and with how I was able to incorporate these changes into my daily life.
Thank you so much, Dr. Irma.

Results vary depending on individual factors such as metabolism, starting weight, adherence to the program, and lifestyle changes. Some clients may begin to see changes in one week, while for others, it may take a few weeks.
My weight loss program focuses on a balanced diet tailored to your specific needs, preferences, and health goals. It emphasizes whole foods, portion control, and nutrient-dense meals rather than restrictive dieting.
The goal is not to eliminate your favorite foods but to learn how to enjoy them in moderation. The program teaches you a new way of eating that can be sustainable and that balance indulgences with healthier choices.
Unlike fad diets, this program is personalized, sustainable, and focused on long-term health rather than quick fixes. It’s designed to help you make lasting lifestyle changes rather than temporary adjustments.
You’ll receive weekly support through consultations of 30 minutes online or presence. During these consultations I give you personalized advice, and resources to keep you motivated and on track. This includes meal plans, other educational material, and lifestyle recommendations.

The focus is primarily on whole foods, but if necessary, specific supplements may be recommended to address any nutritional deficiencies or support your weight loss journey. These will be tailored to your individual needs.
The cost varies depending on the length and scope of the program. I offer two packages to suit various needs and budgets and the difference is the length of the support. Please contact me for detailed pricing information.
