Well-planned vegan is not "just remove and done"
The difference between a healthy vegan diet and one that leaves deficiencies is not in being vegan, but in how you do it. The most common mistake of the beginner is one of subtraction: removing meat, fish, eggs and dairy, and not replacing them with anything equivalent, so the plate is left without protein and the diet without several nutrients. Doing it well is smart substitution: where the animal products went, now go legumes, tofu, tempeh, seitan and fortified plant drinks, and on top of that B12 is supplemented. With that shift in mindset, a vegan diet goes from "going hungry and tired" to being one of the most filling, fibre-rich and healthy ways to eat there is. The key, always, is planning: real vegan food is abundant and varied, not a sad salad.
Vegan protein: anchor it at every meal
The universal question —"where do you get your protein?"— has a more than adequate answer in the plant world: legumes (lentils, chickpeas, beans), soy and derivatives (tofu, tempeh, edamame, textured soy), seitan, nuts, seeds and wholegrains. Together they provide plenty of protein to cover most people needs. The only thing different from animal protein is that almost no plant protein is "complete" on its own: it lacks some essential amino acid. But that is solved by combining legumes and grains across the day, because what one lacks the other has. Soy is the exception: its protein is already complete, as good as animal protein. Anchor one of these sources at every meal and the protein issue is solved.
The 4 key nutrients: B12, calcium, iron and omega-3
A vegan diet covers almost everything if it is based on real food, but four nutrients deserve special attention because they are the ones that fall short without planning:
- Vitamin B12 (mandatory): it is not reliably found in any plant food. Every vegan must supplement it, no exceptions; it is not optional. It is the one gap a vegan diet does not solve on its own.
- Calcium: without dairy, lean on calcium-ENRICHED plant drinks and tofu (check the label), tahini and sesame, almonds and leafy greens (broccoli, cabbage, kale).
- Iron: abundant in legumes, tofu, seeds and leafy greens, but absorbed better with vitamin C. Pair it with pepper, tomato or citrus and keep coffee and tea away from meals.
- Omega-3: include ground flax, chia or walnuts daily (they provide ALA). To secure the DHA, a microalgae omega-3 supplement is the most direct route, with no need for fish.
The structure of each day
Every meal in the plan follows the same skeleton, designed so protein is never missing and the plate is filling:
- Breakfast: protein (soy yoghurt, tofu, soy drink, nut butter) + wholegrain + fruit + an omega-3 source (chia, flax, walnuts).
- Lunch: a legume or soy protein as the base + wholegrain or tuber + half a plate of vegetables + olive oil. It is the main meal.
- Dinner: plant protein (tofu, tempeh, legume) + plenty of vegetables + a light grain. Complete but lighter than lunch.
- Snacks (optional): fruit with nuts, hummus with crudites, soy yoghurt, edamame. They add protein and fill you up.
- Default drink: water. Fortified plant drinks for the calcium; coffee and tea away from iron-rich meals.
The complete weekly vegan menu
An example vegan menu, balanced and with a protein anchored at every meal (legume, soy, seitan or nuts). Amounts are a guide; adjust portions to your appetite and goal. Built-in trick: several dinners are cooked in double batches and reappear at the next day lunch.
| Day | Breakfast | Lunch | Dinner |
|---|---|---|---|
| Monday | Oat porridge with soy drink, banana and peanut butter | Stewed lentils + brown rice + vegetables | Tofu scramble with vegetables + wholegrain bread |
| Tuesday | Wholegrain toast + avocado + tomato + seeds | Chickpea curry + quinoa + spinach | Vegetable soup + hummus with crudites |
| Wednesday | Soy yoghurt + granola + fruit + chia | Bowl of rice, black beans, corn and guacamole | Tempeh stir-fry with broccoli and noodles |
| Thursday | Smoothie of soy drink, oats, banana and almond butter | Wholegrain pasta with lentil bolognese and tomato | Baked falafel + couscous salad |
| Friday | Toast with hummus, tomato and seeds + fruit | White bean stew with vegetables and potato | Homemade wholegrain pizza with vegetables and vegan cheese |
| Saturday | Oat and banana pancakes + soy yoghurt | Free meal WITH structure: plant protein + grain + vegetables | Chickpea and spinach curry with basmati rice |
| Sunday | Tofu scramble with turmeric + wholegrain bread + fruit | Vegetable paella with beans + vegan aioli | Miso soup with tofu and edamame + rice |
The Renzy planner builds a weekly vegan menu made to measure: adapted to your tastes, your allergies and your calories, with the protein of each meal already calculated, the shopping list done and subtracting what you already have in the pantry. And each dish is logged with a photo to confirm you reach the protein, iron and calcium you need.

Batch cooking and adaptations (sport, weight loss, budget)
The skeleton is the same; adjust the pieces according to your case and make it sustainable:
- Batch cooking: cook in batches (a pot of legumes, a base of rice or quinoa, roasted vegetables) 2-3 days a week and combine them. Tonight dinner is tomorrow lunch.
- Sport or gaining muscle: raise the protein (more legume, tofu, tempeh, edamame, seitan and, if you struggle to reach it, pea or soy protein powder) and add grain around training.
- Weight loss: keep protein high, fill half the plate with vegetables and go easy on grain, oil, nuts and vegan ultra-processed food, which concentrate calories.
- Tight budget: the cheap vegan base is dried legumes, tofu, rice, oats, seasonal and frozen vegetables. Eating vegan cheaply is easy if you avoid expensive processed substitutes.
- Gluten-free: replace seitan (it is pure gluten) with tofu, tempeh or legume, and choose gluten-free grains (rice, quinoa, buckwheat, corn).
The most common mistakes
The first, already seen: removing the animal products without replacing the protein, leaving the plate weak. The second, and the most serious: forgetting B12 thinking that "eating healthy is enough"; it is not enough, it must be supplemented, no exceptions. The third: falling into the "ultra-processed vegan", built on plant meat, vegan pastry and fried food, which is no healthier for containing no animals. The fourth: neglecting calcium by using UN-fortified plant drinks (many have no added calcium). And the fifth: not varying, always eating the same two legumes, impoverishing the micronutrient intake. A well-made vegan diet is varied, with protein at every meal, with B12 covered, with fortified foods for the calcium and based on real food.
Eating vegan well is easier than it looks, but it has clear blind spots: almost everyone believes they reach their protein, their iron and their calcium, and many fall short without knowing, especially at the start. That is where Renzy removes the doubt. By photographing your meals you see at a glance whether you really reach the day protein, whether the iron and the calcium are on track and where a legume, a bit of tofu or a fortified drink is missing. With that clear map, keeping a balanced vegan diet stops being a matter of faith and becomes a matter of data: you eat well, varied and animal-free, and you make sure nothing is missing (with the B12 supplemented separately, that one always goes). Because a good vegan diet is not measured by what you remove, but by how well you fill its place.
