The founder

Hello there, nice to meet you!

I'm Selen, Nutrition and Lifestyle Coach, qualified nutritionist and member of the UK Health Coaches Association. I'm the creator and founder of the Alka-Terranean Method® — my signature method that provides fast, sustainable, intelligent weight-loss without dieting.

I spent years in the yo-yo dieting cycle, constantly trying to find ways to lose weight. I went from one diet to the next, losing weight then gaining it all back again.

During my professional career as a Computer Engineer in Digital Banking, these frustrations consumed me mentally. After years of fad diets and spending thousands on nutritionists, my health reached a breaking point. I began to suffer severe digestive problems and at the early age of 24, I had to undergo gastroscopy and colonoscopy procedures.

This was the wake-up call I needed to stop obsessing about dieting and start looking after my health first. The journey to reclaim my health led me to transform my lifestyle and change my eating habits.

Through this process, I not only addressed my health concerns, but I discovered a nutrition method to achieve sustainable weight-loss. I lost 14kg in the first two months and never gained the weight back.

The Alka-Terranean Method® combines the principles of alkaline nutrition — focused on plant-based foods like vegetables, fruits, nuts, legumes and seeds — with the flexibility of a Mediterranean diet and lifestyle.

A strictly alkaline diet requires a high level of effort and many foods are off limits. So while it provides major health benefits, I've combined it with Mediterranean principles for sustainability. A Mediterranean diet allows eggs, poultry, fish, grains, olive oil, and moderate dairy and meat — foods we love, with more variety.

Coming from the Aegean Mediterranean coast of Turkey and having been raised with Mediterranean culture, I understood these benefits firsthand. There is no calorie counting, no strict meal timing, and no food groups are completely off-limits. Through the process, you will intuitively understand how much and when to eat.

The success was so rewarding that I left my career as a Computer Engineer and became a full-time Nutrition Coach. Since 2015, I have coached over 10,000 people. 80% of my clients reached their goals in less than 2 months, with clients losing between 4–12kg in their first month.

What clients say

Over 10,000 people have transformed their health with the Alka-Terranean Method®. Here are some of their stories.

“Thanks to Selen’s approach, I lost more than 20 kilograms (44 lbs) without restricting myself and without dieting while forming healthy eating habits. I learned how to balance my eating and feel confident about it. Finally, after so many years of yo-yo dieting, I have managed to stabilize my weight.”

— Victoria S.

“With Selen’s coaching, I lost 9 kilos in 2 months and kept them off for another 4 months so far. At 36 years old, I’m back to my weight from 7 years ago — a number I believed I would never see again. Selen changed my confidence and brought back my self esteem.”

— Duaa B.

“I had unbelievable results in a short time. In addition to losing nearly 20kg and reaching my ideal weight, I regained my health back and my diet was appreciated by my doctors due to the changes on my hormonal levels.”

— Cagla B.

“Selen has helped me lose over 30 lbs in the duration of my time with her. The best part is that by the end of it, your entire perspective on nutrition and eating habits have changed. Her menus are backed with science, results and deliciousness.”

— Katharine K.

“I lost 10 pounds during my time with her even though I started at a healthy weight. More importantly, my energy and hormonal balance restored. It improved my mood, body and skin! I now feel I have the tools to continue an alkaline diet/lifestyle on my own.”

— Jackie S.

“My boyfriend lost 14 kilograms in 3 weeks! And I started to look a lot fitter and healthier. Most importantly she gave us a new eating habit besides the weight we lost.”
