Targeted programs: Weight loss · Metabolic health · Strength and performance · Longevity
Questions
No. Your plan is flexible and tailored to the foods you like and your daily routine. Nothing is banned; we focus on habits you can keep.
Yes. The weekly calls are online by video, in English or Greek, with online support in between.
The assessment (€120) is your first online call with Markos, by video. He takes your full health history, reads your blood markers (cholesterol, blood sugar, if you have recent tests) and gets to know your goal and your day: how you eat, move, sleep and handle stress. You finish with clear next steps: where you are, what is holding you back, and what to start first. Then Markos builds your 3-month program, tailored to you. You decide after the call, and if you go ahead, the €120 goes towards the program.
Most people notice more energy and better sleep within the first few weeks. Weight, strength and blood results take longer, and the 3 months give them time to change in a sustainable way.
No. Your exercise plan fits what you have: a gym, your home or the outdoors, and the time you can give it each week.
Yes. As a Registered Dietitian, Markos works with medical conditions and blood test results, not just weight. This includes insulin resistance, thyroid conditions, high cholesterol, high blood pressure, metabolic syndrome and eating disorders.
Most people leave with habits they can keep on their own. If you want to keep going, you can carry on with Markos monthly. Ask him for the price.
