Health & Nutrition by Márcia Izzinosa
AMSTERDAM · ONLINE · INTERNATIONAL
Nutrition that respects your story. And supports your everyday life.
I am Márcia Izzinosa, a dietitian in Amsterdam and founder of Health & Nutrition. Since 2005, I have built my career in healthcare and entrepreneurship. My work combines clinical and functional nutrition, taking into account digestive health, metabolism, body composition, sleep, physical activity and the everyday habits that influence well-being. Whether your goal is healthy weight management, more energy, building or preserving muscle, or adapting your nutrition to a new life stage, we create an individual strategy that fits your circumstances. I see clients in Amsterdam and online, with attentive listening, practical guidance and personal follow-up.

MAKING THE FIRST STEP SIMPLE
How my nutritional guidance works

Together we establish priorities and personalised guidance. When appropriate, we can include a body composition assessment.
03 · We follow your progress
We review your habits and results and adapt the strategy to your needs and progress.
Appointments are available at my Amsterdam practice or online, depending on your chosen service.
INITIAL CONSULTATION
Your health deserves a plan that makes sense for you.
You do not need to choose a programme before contacting us. My team can explain the options and help you request an appointment.
Our team will confirm appointment availability. Your initial enquiry is not an automatic booking.
OUR PHILOSOPHY
Your body cannot be separated from your story.
I believe healthy eating is more than counting calories or following a list of restrictions. In my practice I consider food quality, digestive health, sleep, movement, body composition, emotional well-being and, above all, each person’s real life. Having lived in the Netherlands for over 25 years, I have built my career as a dietitian and entrepreneur, supporting people from different cultures and backgrounds. I am a member of Vereniging Arts en Leefstijl, the Dutch association dedicated to lifestyle medicine. My commitment is to translate knowledge into clear, compassionate and sustainable guidance, with personal follow-up and adjustments over time. You do not need to change your entire life to begin caring for your health. You need a strategy that makes sense in your life.
INBODY HEALTH CHECK · YOUR INITIAL ASSESSMENT
Your weight tells only part of your story.
Do you know how your weight is distributed? The scale gives you a number. InBody helps you understand your body composition — a starting point for more informed health decisions.
What can we learn about your body?
Muscle mass: an estimate of muscle quantity, useful for monitoring strength and muscle preservation.
Body fat: estimated quantity and percentage, beyond total body weight.
Visceral fat: an estimated indicator of abdominal fat relevant to metabolic risk assessment.
Body water: an estimate of water distribution in the body.
A quick measurement. A personal explanation.
InBody uses bioelectrical impedance, a non-invasive method that estimates body composition. At my practice, the measurement is accompanied by an explanation of your results in the context of your goals. You do not need to purchase a nutrition programme to book a Health Check.
This assessment can help you monitor body changes, improve habits, begin physical activity or better understand your progress. The figures are estimates, not diagnoses, and may vary with hydration, recent food intake and exercise.
InBody Health Check
In-person measurement and individual explanation of your results, by appointment.

I am Márcia Izzinosa, a dietitian and entrepreneur leading Health & Nutrition in Amsterdam. I have lived in the Netherlands for more than 25 years. In 2005, I founded Excelleres, an important milestone in my entrepreneurial journey. My clinical work developed through close care for the Brazilian community and expatriates from many countries. Over the years, thousands of people have visited my practice, bringing their unique stories, cultures, challenges and goals. This experience strengthened my conviction that nutrition must respect real life. I also try to live what I share in my practice. I value good nutrition, physical activity, rest and consistent healthy habits. I do not pursue perfection: I believe in balance, knowledge and sustainable choices. My work combines clinical, functional and sports nutrition, nutrition education, body composition assessments and support through different life stages, including perimenopause. Attentive listening, clear advice and close follow-up are essential to my approach. Ready to begin caring for your health with personalised guidance?
