Vegan and Vegetarian Nutrition Counseling

Vegan and vegetarian nutrition counseling is a personalized process I run for adults committed to keeping a plant-based diet. My job is not to talk you out of it but to close the gaps that show up in your own labs. The decision on a B12 supplement, and its dose, belongs to your doctor; I build the plan on top of that. Pregnancy, breastfeeding and childhood need closer follow-up.

The advice reaching my plant-based clients tends to sit at two extremes: either "you will end up deficient, give it up" or "you need nothing at all". Neither works. Among the clients I have followed over the years the pattern is this: the problem is not the plant-based diet itself but doing it without a plan, and which gap you actually have only becomes clear once the labs are read. Below I set out what I look at, which decision belongs to whom, and where I stop.

What Does a Plant-Based Dietitian Change on Your Plate?

There are good sources explaining what can run short on a plant-based diet; which food carries what I do not repeat here, I gathered that in the vegan nutrition guide. The work here is different: finding which item on that list is actually short in you. Two vegan clients eating the same menu do not come back with the same labs; absorption, medication, the gut side and how long you have been eating this way all change the picture.

What I see most often in practice is someone who has been plant-based for years treating their tiredness as normal. Yet fatigue, hair loss and breathlessness are frequently signs of a gap that can be measured. That is why I start the process from the labs; writing a supplement on a guess costs more than the price of the jar; it can hide the real gap.

B12: The One Decision That Is Not Debated

B12 is the single heading nobody argues about on a plant-based diet. Because its reliable sources are animal foods and fortified products, securing this side through menu changes alone is not realistic in a fully vegan adult. The decision to supplement, the form and the dose belong to your doctor; my job is asking for your level to be monitored and building the plan around that decision.

One warning as well: a B12 deficiency can progress without producing the anaemia picture when the diet is rich in folate, so "my blood counts are fine" does not always mean "B12 is fine". The symptoms and the monitoring side I set out in the B12 deficiency guide; the decision is made together with your doctor.

Protein and Iron: Spread and Absorption, Not Amount

On a plant-based diet the protein question is usually asked as "is it enough", when the real issue is how it is spread across the day. Legumes piled into one meal give a different result from the same amount spread over three, and breakfast is the weakest link for most clients. Varying the sources matters for the same reason, far more than any "combine these two at every meal" rule.

On the iron side the conversation is about absorption rather than amount. Absorption of plant iron is affected by tea and coffee taken close to a meal, by the timing of a calcium supplement, and by whether the meal carries a vitamin C source. So I build the plan around those hours. If ferritin is low, finding out why is your doctor's work; the nutrition side runs alongside it.

How the Weeks Move

  • A personalized program built around your labs and the pattern you have chosen, with plant-based recipes alongside it.
  • Photo meal analysis: you send a photograph of the plate, so you do not have to describe what you ate.
  • A voice call every two weeks, with WhatsApp message support in between.
  • Label-reading practice: we work through hidden animal ingredients and fortified products together.
  • The plan updated within the same week whenever a new lab result arrives.

The scope is the same in all three packages; only the duration and the fee change, and call frequency does not. Calls are voice only; video consultations are not offered. The process runs entirely online, so where you live makes no difference. Payment is taken by bank transfer and fees are not refunded.

Where Is the Line in Sensitive Periods?

Pregnancy, breastfeeding, infancy and the growing years stand apart under this heading. A plant-based plan for a child or a pregnant client needs closer monitoring and I do not run that process alone: where medical follow-up continues and the growth curve or the pregnancy is being tracked by your doctor, we can work on the nutrition side together. Adding a new restriction for a child is not my call.

The other places I stop are equally clear. Where an eating disorder has been diagnosed, a plant-based diet can sometimes become the cover for the restriction; there psychiatry and psychotherapy come first and the nutrition side runs only alongside that team. In malabsorption, after bariatric surgery and in advanced kidney disease the plan is built together with the relevant doctor.

These are not nutrition matters but doctor's work: numbness or tingling in the hands and feet, unsteadiness, forgetfulness and a burning tongue; hair loss that speeds up; breathlessness and palpitations on exertion; periods stopping. In any of these nothing waits; you contact your doctor.

What Do I Look at to Start?

You can send your application through WhatsApp at no charge; our assistant receives your initial request. I send the intake form; you send it back with your recent labs, a list of the supplements you take and how long you have been eating this way. If you have no labs in hand I tell you which tests to ask your doctor for. Nothing is prescribed during the intake assessment.

The programme reaches you within a few business days. After that we speak by voice every two weeks, and what we read is not a single value but a direction: whether the tiredness is easing, whether the meals are genuinely workable, where the lab trend is heading, and whether the plan has narrowed your social life. The duration is set by the package, and which one suits you we decide together during the intake assessment.

If You Have a B12 Result, We Start From There

We close the gaps without asking you to give up a plant-based diet. The process runs entirely online and does not replace your medical follow-up.

Frequently Asked Questions

You can send your application through WhatsApp at no charge; our assistant receives your initial request. You send the intake form, your recent labs and a list of the supplements you take. If you have no labs I tell you which tests to ask for. Nothing is prescribed during the intake assessment.
In a fully vegan adult, securing this side through the menu alone is not realistic. Whether a supplement is needed, in what form and at what dose is your doctor's decision; my job is asking for your level to be monitored and building the plan around that.
You can; the real issue is spread across the day rather than amount. Legumes piled into one meal give a different result from the same amount across three, and breakfast is the weakest link for most clients. Varying the sources helps more than any "combine these two" rule.
You do not. With plant iron the real subject is absorption: tea and coffee close to a meal, the timing of a calcium supplement and whether the meal carries a vitamin C source all change the picture. I build the plan around those hours. Why ferritin has fallen is for your doctor to assess.
Finding the cause is the doctor's work; anaemia does not always come from the diet. I correct the gap on the nutrition side and the habits blocking absorption. Which sources carry iron and how it is absorbed better I gathered in the iron deficiency guide.
It does. With eggs and dairy on the table the B12 and iron side is built differently and the calcium question usually shrinks. Lacto-ovo, pescatarian and flexible vegetarian patterns each produce a different plan; we settle which one you are on during the intake assessment.
A gradual transition holds better for most clients: first we build the meal skeleton, then we take things out. The most common result of stopping abruptly is drifting towards bread and pasta. The roadmap for the transition I set out in the vegetarian nutrition guide.
For a child and through the growing years I do not run the process alone. Where medical follow-up continues and the growth curve is being tracked we can work on the nutrition side together; adding a new restriction for a child is not my call. That side we run under child and infant dietitian. The same frame holds in pregnancy and breastfeeding.
The most common reason is that the space left by animal foods gets filled with bread, pasta and ready-made vegan products. Those are plant-based but they do not satisfy. Once the meal skeleton is rebuilt around legumes, whole grains and nuts, the picture changes on its own for most clients.
You can; the planning is simply more detailed. Meal placement around training hours, spreading protein sources across the day and the iron side all come to the front. If performance is dropping we look at the labs first rather than adding a supplement on a guess.
Calls are voice only; video consultations are not offered. We speak every two weeks throughout the programme, and in between meal photographs, new labs and questions come through WhatsApp. Call frequency does not change by package.
Only the length of the package. The scope is identical in all three: a personalized program, photo meal analysis, a voice call every two weeks, measurement tracking, WhatsApp support and recipe support. After your free application, we review which duration suits your needs in the subsequent communication. Payment is by bank transfer and fees are not refunded.
