10,000+ clients coached·the Alka-Terranean® method since 2015

A nutritionist who
works by balance.

Not a dashboard. Not another diet to fail at. Selen is your nutrition coach, built on the Alka-Terranean® method — Mediterranean balance, real meals, no restriction. She guides what to eat next, keeps you gently accountable, and remembers everything you tell her: the foods you love, the weeks that throw you off, what worked last time. Pasta, wine, dinners out and all — until eating well feels easy again.

Good. Tuesdays move fast — I remember. Put a tomato or some cucumber beside the eggs and you’ll hold steady till noon without thinking about it.
lunch was the chickpea salad you mentioned
That’s the one. Eat it slowly, by the window if you can. You always feel better when lunch isn’t at your desk.

Why nothing’s working

You did everything right.
Restriction was never going to work.

You ate less. You chose the cleaner option. You were disciplined — and still felt stuck. That isn’t weakness. Cutting harder and harder only leaves you depleted, and depletion is what lets the next craving win. The way out was never more restriction. It’s balance — enough structure to feel real progress, enough room to keep your life.

Not a willpower problem Not a metabolism problem Not a discipline problem

The Alka-Terranean® method works by addition: more protein, more plants, more rhythm, more of what steadies you — long before anything is taken away. Eat the pasta. Pour the wine. Keep the dinners out. Selen helps you make real meals work, one ordinary day at a time.

How it works

From download to first
reply in a few minutes.

No food scales, no calorie targets, no setup you’ll dread. You tell Selen a little about yourself, and the conversation starts the same day.

01

Tell her about you

A few questions, in her voice, not a form: what you’d like to feel, the foods you love, how your weeks usually go. She remembers all of it from here.

02

Talk through your days

Send a photo of your plate, a line about dinner, or a voice note on the walk home. However it’s easiest. She reads it and writes back like a person.

03

She learns your rhythm

Day by day she gets you better: what steadies you, what throws you off. On Sunday a letter arrives, reading your week back to you.

Four rooms, one relationship

The whole app is a room,
not a dashboard.

Chat is the relationship. Diary is the evidence. Today is the next step. On Sunday, a letter makes sense of the week. Four rooms, one conversation that never resets.

01

Today

Where the day starts. One thing she is holding for you, one small step worth taking, and a place to tell her what just happened.

02

Chat

The relationship itself. Send a few words, a photo, or a voice note. She answers in her own voice, already holding everything you have told her.

03

Diary

Your evidence, not a nutrition table. The photo, the menu, the meal you mentioned, each one with Selen’s read of it in plain words, grouped by day.

04

You

Everything Selen knows about you, written as plain sentences you can change or hide. Membership, and the channels she reaches you on. Nothing to manage.

One room, many ways to use it

She meets you
where you are.

Some weeks you talk everything through; other weeks you would rather be left alone and simply told how you are doing. However you reach her — in the app, on iMessage, or on Telegram — it’s the same Selen, holding the same thread.

Conversational

Voice notes, long threads, a coach you talk to most days.

Insight-first

Little chatting. Clear daily and Sunday reviews that explain the week.

Tracker-light

Capture and evidence, without much back-and-forth.

Sustain

You have arrived. She keeps watch and stays out of the way.

Program-led

A reset or boot camp, turned into one personal next step a day.


Coaching in conversation

A conversation,
not a chatbot.

Tell her what you ate in whatever way is easiest, and she keeps the thread of it for you.

Send a sentence, a photo of your plate, or even the menu before you order — point your camera and she reads the whole thing, then tells you what to choose for the way you eat. She writes back like a person, and already holds what you told her last week: the late Tuesdays, the olives over almonds, the way restaurants make you anxious. Nothing here is forbidden and nothing needs undoing. She simply tells you the next thing worth doing.

  • empty“Tell me everything. I’ll keep it.” The room opens with an invitation, not a form.
  • thinking“thinking with you…” She takes a beat, the way a person does before answering.
  • alwaysWords, a photo, or a held voice note. Whatever is easiest in the moment.

How she remembers

She learns you,
and keeps learning.

You want restaurant confidence without tracking every bite. She wrote that down the day you said it.

Every correction, every plate, every note on how it sat makes her picture of you a little truer. A small seal shows how well she knows you now, never how well you are doing. It measures her understanding, not your worth.

  • holdsFoods you love, the ones you don’t, the real shape of your week.
  • noticesThat mornings set the tone, that travel undoes you, that you skip lunch when you’re busy.
  • yoursEvery fact is a plain sentence you can confirm, correct, hide, or tell her is no longer true.

She reaches out first

You won’t have to
remember to check in.

Most coaching waits for you to start. Selen is the one who reaches out — so the days you’d have gone quiet are the days she’s already there.

A note in the morning with the one thing worth doing. A gentle word after a week she could tell was heavy. The Sunday letter, landing before you think to ask. Never a nag, never a streak to keep — just someone who noticed, and said so.

Grounded coaching

Ask her why.
She shows her work.

Selen tracks evidence, not obedience. Every line she says traces back to something you actually told her.

Tap “why are you saying that?” and she lays out what is behind the thought: a habit she remembers, a meal you captured, a note from the method, and the part she is still unsure of. When the evidence is thin, she says so and asks you a question, rather than pretending to know.

The whole picture

She sees more than
the plate.

With your permission, Selen reads what your body is already telling her: weight, sleep, steps, your cycle, straight from Apple Health.

She reads it as context, never as a verdict. A heavy Monday on the scale is water, not a failed week. A stall is usually late dinners and fewer steps, not a lack of will. She holds all of it lightly, and only brings it up when it helps you.

  • “The trend is moving. Monday was water, not a failed week.
  • “Your dinners ran later and your steps dropped. That may be the stall, not you.
  • “You’re near the end of your cycle. Be kind to yourself this week.

Your body’s data,
where it already lives.

Today she reads weight, sleep, steps and your cycle from Apple Health, and the rings you close from Apple Fitness. Soon she’ll read the rest — the recovery you slept off, the strain of a hard week — and hold all of it as gentle context, never a verdict.

The Alka-Terranean® method

Olive oil, bread, fish,
wine, sun, slowness.

Selen’s own method, trademarked and built over a decade of coaching: Mediterranean flexibility with the logic of alkaline balance underneath. The idea is simple — you add before you take away. More plants, more protein, a steadier rhythm, until the day comes back into balance on its own. No restriction, no calorie counting, no guilt.

Read the full method, explained

I

Balance, not bans

A heavy, acid-producing lunch is not a failure to undo. It is a note for what comes next: Selen makes the next meal vegetable-heavy — a salad, good olive oil — and the day comes back into balance.

II

Rhythm over rules

When you eat matters as much as what you eat. Greens early, a lighter evening, a real pause at the table. The rhythm does most of the work.

III

Your body, listened to

Bloating, energy, sleep, the cycle. What you feel after eating is information, not a verdict, and the method follows your body instead of a chart.

The evidence ledger

The diary
writes itself.

Whatever you tell her, she keeps — a record led by what you remember, not a row of numbers.

The photo, the menu, the meal you mentioned in passing: each one lands here with Selen’s read beside it, in plain words. There are no barcodes to scan and no calorie column to fill. When she spots a pattern, she shows you the entry that proves it.

  • leadsA photo, a menu, a meal name, or a voice note. What you remember comes first.
  • readsSelen’s interpretation in prose, with your corrections kept close.
  • provesA small weekly rhythm in seven bars, never a calorie headline.

Selen watchesEnergy, digestion, and the patterns worth keeping past day ten.
The Sunday letter

Your week,
read back to you.

Every Sunday a letter arrives. Not a report card, and not a chart: what happened, what helped, what got in the way, and one thing to try next.

It is writing first. Selen’s voice on the page, with the numbers there only to back up a sentence. You’ll read it more than once.

The Sunday Letter
Week two · for Maya

You found your middle gear.

Last week was restraint. This week something gentler took over — you stopped negotiating with breakfast, and the rest of the day followed.

The two evenings that ran late, you felt the next morning, and you knew it before I said a word. That is the part that lasts.

Next week, one thing: a real pause before dinner. Five minutes, nothing more.

— Selen

In their words

The coaching they
couldn’t stop talking about.

After years of trying to find a diet that fit my life, I lost more than twenty kilos — without restricting myself, without dieting — while building habits I actually kept. I finally learned to balance my eating, and to feel confident about it. She never judges you. Only the opposite.
Victoria S. Victoria S.Lost 20 kg, no dieting · coached by Selen

“I’m back to the weight I was seven years ago — a number I thought I’d never see again. I stopped hiding under baggy clothes and just feel like myself.”

Duaa B.Duaa B. · coached by Selen

“The whole mindset was adding to my meals, not taking away. I started craving better food — and leaned out eating more and training less.”

Elena G.Elena G. · marathon runner

“Weight loss wasn’t even my goal. I feel lighter, sleep less, snap less — and more in control of my habits than I’ve ever been.”

“Over thirty pounds across my time with her, but the real change is mental: by the end, my entire perspective on eating had shifted.”

“I’ve tried a lot of diets. This is the most sustainable one — you stick with it without torturing yourself. She taught me to balance and compensate.”

The voice behind the room

I built the coach I wish every woman could sit with.

I started as a computer engineer, not a nutritionist — until I gained thirty pounds and found that nothing the industry was selling fit the life I was actually living. So I built my own way back, and then I built it for everyone else. For years I’ve sat across the table from women — thousands of them — tired of every diet, asking the same question: what do I eat tomorrow? The Alka-Terranean® method is my answer: Mediterranean rhythm, alkaline balance, and the patience to listen to your own body. It has never once asked anyone for a spreadsheet. My work’s been featured in Forbes, The Guardian, The Economist and The Telegraph, and on the cover of GOSS — but the part I’m proudest of is the woman who finally stopped dreading dinner.

You don’t need another diet. You need someone who remembers what you ate on Tuesday, and what you said about it on Wednesday.

answers.

Is alkaterra a diet?
No. alkaterra is coaching built on the Alka-Terranean® method — Mediterranean balance with alkaline principles. There is no restriction, no calorie counting and no guilt. Selen helps you balance what you already eat, adding rather than removing.

You tell Selen what you ate, by text or voice, and she replies with one calm, specific next step. She remembers your meals, your patterns and what worked last time, so the guidance gets more personal the longer you use it.

No. There is no calorie counting and no rigid tracking. You share meals when it feels natural — a photo, a sentence, a menu before you order — and Selen keeps the thread for you.
