Find the answer you are looking for quickly. If your question is not on the list, write to us; we resolve it in a short time.

Subscription and Cancellation

Is Diet Prof free?

The diet test and body analysis are free; the personalised diet plan is paid.

Without signing up you can complete the diet test and see your body mass index, daily calorie needs, ideal weight and how long it will take to reach your goal — free of charge.

A plan is required for features such as your personalised diet list, recipes, shopping list, meal reminders and dietitian support. We offer different durations, from one week up to six months.

Prices vary by country and by seasonal campaigns, so you will see the price that applies to you on the Packages page.

How do I cancel my subscription?

You can cancel your subscription from your profile with a single click — there is no need to write to us.

  1. Sign in to your account
  2. Open the Services page
  3. Click the cancel button in the Subscription Management section
  4. Answer Yes to "Do you confirm the cancellation of your subscription?"
  5. Optionally select your reason for cancelling and click Confirm Cancellation

Your cancellation is processed immediately and you will see a confirmation screen.

Will my plan close immediately when I cancel?

No. Everything stays open until the end of the period you have paid for.

Even though your subscription is cancelled, your diet list, recipes, shopping list and all other features keep working without interruption until the end of your current plan period. Your membership ends automatically after that date.

In other words, cancelling does not cut your access short — you use the time you are entitled to, right to the end.

Does the subscription renew automatically?

Subscription packages renew automatically unless you cancel.

You benefit from an introductory discounted rate on your first payment. Subsequent renewals are made monthly at the standard price, charged to the card you used for your first payment.

If you cancel at least 24 hours before the current term ends, no new charge is made. You can see the current amount and the renewal date on the Services page.

Can I change my package?

A package cannot be changed while a plan is still running.

If you would like to move to a different package, you need to wait until your current plan period ends. Once it has ended you can choose any package you like from the Packages page.

If your plan is a subscription, cancel it first so that it does not renew automatically with the same package at the end of the period.

Can I pause my subscription?

We do not currently offer an option to pause a subscription temporarily.

If you would like to take a break, you can cancel your subscription. You continue using your plan until the end of the period you have paid for, and no further charges are made after that.

Your information is not deleted. Your form details, measurements and past records stay in your account, so you can continue with the same account when you come back.

Payment, Invoice and Refund

I see "DIETPROF SUBSCRIPTION" on my card. What is this?

This is the payment for your Diet Prof diet subscription.

On your card statement or card activity you may see either "DIETPROF SUBSCRIPTION" or "DIETPROF.COM PLAN". Both belong to the same service: the personalised diet plan subscription you purchased through dietprof.com.

Unless you cancel it, your subscription renews automatically on a monthly basis at the end of the period; this is why you see a charge for each period. Because your first payment is at a promotional rate, the renewal amount may differ from your first payment.

If you have a question about a charge, write to us from the Contact Us page with the date and amount of the transaction; we will find the record and share the details with you. We resolve your request in a short time.

Which payment methods do you accept?

We accept payment by credit card and debit card.

You can pay securely using 3D Secure. All cards used worldwide are accepted.

Your card details are never recorded or stored by us. Payments and subscription charges are processed through the secure system of the relevant payment institution.

My payment failed, what should I do?

If your payment could not be completed, it is usually a temporary situation with the card.

The most common reasons:

  • Insufficient limit or balance
  • The card has expired
  • Your bank stopping the transaction for security reasons

A short call with your bank resolves most cases. If a renewal payment fails, the system automatically retries within a few days; your plan stays open during this time.

If the problem continues, write to us from the Contact Us page; we resolve it in a short time.

How do I get my invoice?

You can download your invoice yourself from the Services page.

  1. Sign in to your account
  2. Open the Services page
  3. Click the receipt icon next to the relevant payment

Your invoice opens in a new tab; from there you can download or print it. You can reach the invoices for all your past payments on the same page.

If you cannot access your invoice, write to us from the Contact Us page.

What is your refund policy?

Under applicable consumer legislation, digital services that are delivered instantly after purchase are not subject to a right of withdrawal.

Because your diet plan is created and assigned to your account the moment payment is completed, refunds cannot be issued for subscription fees. This is not a practice specific to us; it is a legal arrangement that applies to all digital services delivered instantly.

Even if you cancel your subscription, you continue to benefit from all features until the end of the period you have paid for.

If you have experienced a problem with the service, please write to us anyway. We review your situation and resolve it in a short time.

What We Offer

What does Diet Prof offer?

Diet Prof is much more than a diet list prepared for you.

Features you can use with your subscription:

  • Personalised diet list — prepared according to your height, weight, goal and habits
  • Recipes — with ingredients, quantities and calories
  • Meal swapping — you can change a meal you do not like
  • Shopping list — daily and weekly, created automatically
  • Meal reminder — you receive reminders at your meal times
  • Dietitian support — send your questions directly to our dietitian team
  • Analysis results — your BMI, basal metabolism, calorie and water needs
  • Change graphs — follow your weight and BMI change on a graph
  • Timeline — shows how long it will take to reach your goal and ideal weight
  • Test results — record and follow your blood values; we can update your diet list according to them
  • PDF download — download and print your diet list
  • Diet settings — set your own number of meals and meal times
Are there recipes and ingredients for the meals?

Yes. Most of the meals in your diet list include a step-by-step preparation recipe.

For each meal you see:

  • Ingredients and their quantities — how many grams, how many pieces, how many spoons
  • Preparation — step-by-step instructions
  • Calorie value
  • Photo of the meal

You can open the recipe by clicking on the meal. You can also reach the recipes from your shopping list.

How does the meal reminder work?

You define your meal times and the system reminds you at those times.

All you need to do is click the "Define My Meals" button on the Meal Reminder page. Your meals are transferred to your Google Calendar and you receive a notification on your phone at each meal time.

You can change your meal times at any time from the Diet Settings page.

What is the shopping list?

It is a list that automatically works out the ingredients you need to buy for the meals in your diet list.

You can view it in two ways:

  • Daily — the ingredients for that day
  • Weekly — to do a whole week's shopping in one go

The quantities are shown as well, so you do not have to work out how much to buy at the shop. You can also see which meal each ingredient on the list is used in.

How do I get dietitian support?

You can send your question from the Dietitian Support page in your profile.

  1. Open the Dietitian Support page
  2. Create a new request
  3. Write your subject and your question, then send it

Our dietitian team reviews your request and replies. You see the reply on the same page and can continue the conversation if you wish.

You can reach all your past requests and their replies on this page.

What do the analyses and graphs show?

You follow your health values and your progress on two separate pages.

On the Analysis Results page:

  • Your Body Mass Index (BMI) value
  • Your Basal Metabolic Rate (BMR) value
  • Your daily calorie need
  • Your daily water need
  • Your ideal weight and your goal weight

On the Change Graphs page you see how your weight and your BMI value have changed over time on a graph. This way you can follow your progress in concrete terms.

What is the timeline?

It is the calendar that shows how long it will take you to reach your goal.

On the Timeline page you see two separate calculations:

  • Goal Weight - Your Timeline: in how many days/months you will reach the goal weight you set yourself
  • Ideal Weight - Your Timeline: in how many days/months you will reach the ideal weight for your height

The calculation assumes that you follow your diet programme.

Can I enter my test results?

Yes. You can record your blood values from the Test Results page.

The values you enter are reviewed by our dietitian team and, if necessary, your diet list is updated accordingly.

Entering test information is not compulsory; you can use your diet list without entering it.

Important notice: Diet Prof does not provide medical diagnosis, treatment or medical advice. The test values you enter are used only to prepare your nutrition programme more suitably for you; they are not interpreted medically and do not replace a health assessment. If you have a chronic condition, take regular medication, are pregnant or are breastfeeding, please consult your doctor before starting the programme.

Can I download my diet list as a PDF?

Yes. You can download your programme as a PDF from the Download Diet Plan page.

You can print the file you download, keep it on your phone, or use it when you have no internet connection.

The PDF download feature is available to members with an active subscription.

Diet Plan

When will my diet list be ready?

Your list is created as soon as your payment is completed and it is waiting for you in your profile.

You do not need to wait or expect an e-mail from us. After payment you are taken straight to your profile page; your list is ready on the Diet Plan page.

If you cannot see your list, refresh the page once. If the problem continues, write to us from the Contact Us page; we resolve it in a short time.

How many days does my plan cover?

The length of your plan is determined by the package you purchased.

If you bought a one-month package, a one-month programme is set up; if you bought a three-month package, a three-month programme.

Your programme does not stay fixed throughout the period — as your weight and measurements change, your list is recalculated and updated. This way the programme always matches your current situation.

When your subscription renews, a new programme is created for the new period.

There is a food I dislike or am allergic to, what should I do?

You can change a meal you do not like or are allergic to with a single click.

On the Diet Plan page, just click the change icon next to the relevant meal. Another meal from the same category and with the same calorie value will appear.

If you have a serious food allergy or a medical restriction, do not rely on swapping the meal alone — let us know from the Dietitian Support page so that your programme can be adjusted accordingly.

How does meal swapping work?

On the Diet Plan page you click the change icon of the meal you want to replace, and the meal is instantly replaced with a new one.

The new meal is chosen from the same category (breakfast, snack, dinner, etc.) and in line with the calorie balance of your programme. So your diet is not disrupted when you make a change.

You can change it more than once until you find one you like.

Can I change the number of my meals and their times?

Yes. From the Diet Settings page you can set both the number of your meals and your meal times yourself.

For example, if you do not want a snack you can turn it off, and you can move your breakfast time earlier or later according to your working routine.

The change you make is reflected in your next programme. Your meal reminders also work according to the new times.

What if I cannot lose weight?

If you are following the programme but not getting the result you expected, let us know — we will review your programme.

The rate of weight loss varies from person to person; metabolism, age, activity level, sleep and hormonal factors all affect the result. For this reason we do not give a specific weight guarantee.

If you are not seeing the progress you expected, write to us from the Dietitian Support page. Our team reviews your situation and makes the necessary adjustments to your programme. You can follow your progress on the Change Graphs page, and by entering your test values you help us prepare your programme more accurately.

Account and Login

How do I sign up?

When you complete the free diet test you are taken to the registration step.

  1. Open the Diet Test and answer the 12 steps (about 2 minutes)
  2. When the test ends, your analysis results appear on the screen
  3. Click the Sign Up button and fill in your details
  4. Click the verification link sent to your e-mail address

Registration is free. You do not need to pay to see your analysis results.

If the verification e-mail has not arrived, check your spam folder.

I forgot my password, what should I do?

You can reset your password from the "Forgot Password" link on the login page.

  1. Open the Login page
  2. Click Forgot Password
  3. Enter your registered e-mail address
  4. Click the link sent to your e-mail and set your new password

Your password must be at least 6 characters and contain one uppercase letter, one lowercase letter, one number and one special character.

If the e-mail has not arrived, first check your spam folder. If it still does not arrive, write to us from the Contact Us page. You can be sure we will resolve it.

How do I update my information?

Your information is kept on two separate pages; open the one that matches what you want to change.

From the My Information page:

  • Name, surname, date of birth
  • E-mail, phone
  • Country, city
  • Profile photo and password

From the Form Information page:

  • Height, weight, goal weight
  • Chronic conditions, habits, activity level

When you update your form information, your diet programme is recalculated according to your new values. That is why updating it as your weight changes keeps the programme suited to you.

Can I change my e-mail address?

Yes. You can update your e-mail address from the My Information page.

After the change you sign in with your new e-mail address. Notifications, invoices and password reset e-mails are also sent to the new address.

Be careful when typing the address — if you enter it incorrectly you will not be able to sign in and will not receive the password reset e-mail. In that case, write to us from the Contact Us page and we will correct it.

How do I delete my account?

If you want your account deleted, send your request from the Contact Us page.

On your request, your account and your personal data are deleted; we complete the process in a short time.

What you should know before deleting:

  • If you have an active subscription, cancel it first — even if the account is deleted, charges may continue if the subscription is not cancelled
  • Your diet lists, measurements and past records are deleted irreversibly
  • Payment and invoice records are retained for the legally required periods as the regulations require

If you want to take a break, cancelling your subscription is enough instead of deleting your account — your information stays and you can come back whenever you like.

Security and Trust

Is Diet Prof reliable?

Diet Prof is an online diet platform that operates globally and is used in many languages and many countries.

We do not give you a ready-made list. Your height, weight, goal, chronic conditions, daily activity level and meal habits are calculated to create a programme that belongs only to you. The programme is updated as you change — as your weight changes, your list is recalculated.

There is a real dietitian team behind it; you send your questions directly to them and receive your answer in your profile.

So that you can use it with confidence:

  • Secure payment — Payments are taken through a payment institution with international security standards, with 3D Secure verification. Your card details are not recorded or stored by us.
  • One-click cancellation — You can cancel your subscription yourself from your profile. There is no need to call us or send an e-mail.
  • No charge after cancellation — When you cancel your subscription, no new charge is made to your card.
  • Transparent terms — Our pricing, cancellation and refund terms are clearly set out in the Terms of Use and the Sales Agreement; you can read them before purchasing.
  • Solution-focused support — We resolve every request in a short time.
  • Data security — The site runs over an encrypted connection (SSL) throughout; your personal data is processed in line with our Privacy Policy.
How is my personal data protected?

Your personal data is processed only to prepare your personalised diet programme and to provide the service.

  • Your data is transmitted over an encrypted connection (SSL)
  • Your card details are never stored in our system
  • Your health information is used only in preparing your diet programme
  • Your information is not shared with third parties for marketing purposes

Yes. Your card details are never recorded or stored by Diet Prof.

The card details you enter when paying are transmitted directly to the system of a payment institution with international security standards. Your card number, expiry date and security code are not held on our servers.

Payments are made with 3D Secure verification — meaning your bank verifies you separately during the transaction.

Our entire site runs over an encrypted connection (SSL); the information you enter is protected while it is transmitted.
