| + > **Quick answer:** To go vegan, start by swapping the meals you already eat for plant-based versions, add a reliable **vitamin B12** source from day one, and learn to spot animal ingredients on labels. Most people find it easiest to go step by step (one meal, then one day, then everything) or to commit to a fixed 30-day trial. A well-planned vegan diet is considered suitable at every life stage by the Academy of Nutrition and Dietetics. |
| + |
| + ## Key facts |
| + |
| + - **Definition:** The Vegan Society defines veganism as a way of living that seeks to exclude, as far as is possible and practicable, all forms of exploitation of, and cruelty to, animals for food, clothing or any other purpose ([Vegan Society](https://www.vegansociety.com/go-vegan/definition-veganism)). |
| + - **B12 is the one non-negotiable:** the Vegan Society advises fortified foods providing at least 3 µg a day, *or* a daily supplement of at least 10 µg, *or* a weekly supplement of at least 2,000 µg ([Vegan Society](https://www.vegansociety.com/resources/nutrition-and-health/nutrients/vitamin-b12/what-every-vegan-should-know-about-vitamin-b12)). |
| + - **Vitamin D:** in the UK the NHS advises everyone to consider 10 µg a day in autumn and winter, and to check that the vitamin D in a product is not of animal origin ([NHS](https://www.nhs.uk/live-well/eat-well/how-to-eat-a-balanced-diet/the-vegan-diet/)). |
| + - **Also plan for:** iodine, omega-3 fats, calcium, iron and zinc (see [[vegan-diet-and-health]]). |
| + - **Professional position:** appropriately planned vegan diets are "healthful, nutritionally adequate, and may provide health benefits" ([Academy of Nutrition and Dietetics, 2016](https://doi.org/10.1016/j.jand.2016.09.025)). |
| + - **No single right method:** gradual and immediate transitions both work; the best one is the one you can keep. |
| − **Going vegan** refers to the process of transitioning from a diet and lifestyle that includes animal products to one that excludes them, in line with the principles of [[veganism]]. People make the change in many different ways, and there is no single correct method. This article summarises common approaches and practical considerations. |
| ## Choosing an approach |
| Transitions generally follow one of two patterns: |
| - **Gradual transition.** Animal products are removed step by step, for example by first eliminating meat, then fish, then eggs and dairy. Some people start with one fully vegan meal or day per week and build from there. This approach allows time to learn new recipes and shopping habits. |
| - **Immediate transition.** Some people switch all at once, often prompted by a documentary, a personal decision or a structured challenge such as [[veganuary]]. A fixed trial period, commonly 30 days, can make the change feel manageable. |
| Neither approach is universally recommended; the most suitable one depends on the individual's circumstances, cooking experience and household. |
| ## Step-by-step guide |
| 1. **Learn the reasons.** Understanding the ethical, environmental and health arguments, such as those covered in [[ethical-veganism]], [[factory-farming]] and [[environmental-impact-of-animal-agriculture]], helps many people stay motivated. |
| + 2. **Start with familiar meals.** Many common dishes are already vegan or easily adapted, such as pasta with tomato sauce, bean chilli, vegetable curry, stir-fries and lentil soup. Browse [vegan recipes](/recipes) for ideas such as [lentil bolognese](/recipe/lentil-bolognese) or [coconut chickpea curry](/recipe/coconut-chickpea-curry). |
| − 2. **Start with familiar meals.** Many common dishes are already vegan or easily adapted, such as pasta with tomato sauce, bean chilli, vegetable curry, stir-fries and lentil soup. |
| 3. **Find substitutes.** Products such as [[plant-based-milks]], [[vegan-cheese]], [[tofu]], [[tempeh]], [[seitan]] and meat alternatives can replace familiar foods. [[egg-substitutes]] and [[aquafaba]] are useful in cooking and [[vegan-baking]]. |
| + 4. **Plan nutrition.** Take a reliable source of [[vitamin-b12]] from the start, either fortified foods or a supplement. Also consider [[vitamin-d]], [[iodine]], [[omega-3-fatty-acids]], [[calcium]], [[iron]], [[zinc]] and [[protein]]. A registered dietitian can provide individual advice; our directory lists [vegan-friendly nutritionists and dietitians](/nutritionists). |
| + 5. **Read labels.** Learn to recognise animal-derived ingredients such as whey, casein, gelatin, carmine and shellac (see [[hidden-animal-ingredients]] and the [is it vegan? ingredient checker](/is-it-vegan)). [[vegan-certifications-and-labels]] can make shopping quicker. |

| 6. **Plan meals and shopping.** Simple [[meal-planning]] reduces stress and waste. Staples such as beans, lentils, grains, oats, frozen vegetables and seasonal produce keep costs low (see [[vegan-on-a-budget]]). |
| + 7. **Handle social situations.** Look up menus in advance, tell hosts about dietary needs and offer to bring a dish. See [[eating-out-as-a-vegan]], [[vegan-travel]] and the [vegan restaurant directory](/restaurants). |
| + 8. **Extend beyond food.** Many vegans gradually replace leather, wool and other animal-derived materials as items wear out, and choose [cruelty-free cosmetics](/cruelty-free) and household products. Using up existing non-vegan items before replacing them is a common, pragmatic choice (see [[vegan-fashion]]). |
| + |
| + ## A 4-week starter plan |
| + |
| + This is one common way to structure a gradual transition. It is a suggestion, not a rule. |
| + |
| + | Week | Focus | Try this | |
| + |---|---|---| |
| + | 1 | Breakfast and drinks | Switch to a fortified [plant milk](/wiki/plant-based-milks); try [overnight oats](/recipe/berry-chia-overnight-oats), [tofu scramble](/recipe/tofu-scramble) or [pancakes](/recipe/fluffy-vegan-pancakes). Start a B12 supplement. | |
| + | 2 | Lunches | Bean or lentil soups, hummus wraps, grain bowls, leftovers. Learn three go-to lunches. | |
| + | 3 | Dinners | Cook vegan versions of your family's favourites: chilli, curry, pasta, stir-fry, tacos. | |
| + | 4 | Snacks, eating out, the rest | Read labels on snacks and sauces, find local [vegan places](/restaurants), and decide how you'll handle cosmetics, clothing and household products. | |

| ## Building a balanced plate |
| A widely used guide for vegan meals is to include, over the course of the day: |
| | Food group | Examples | |
| |---|---| |
| | Legumes | Beans, lentils, chickpeas, peas, tofu, tempeh | |
| | Whole grains | Oats, brown rice, wholemeal bread, quinoa, barley | |
| + | Vegetables and fruit | At least five portions, a variety of colours, including leafy greens | |
| + | Nuts and seeds | Walnuts, ground flaxseed, chia, hemp seeds, tahini | |
| + | Fortified foods | Fortified plant milks and yoghurts, breakfast cereals, nutritional yeast | |
| + |
| + This mirrors the NHS's advice for vegans: base meals on starchy foods, eat beans, pulses and other proteins regularly, choose fortified dairy alternatives, and include omega-3-rich nuts and seeds such as walnuts every day ([NHS](https://www.nhs.uk/live-well/eat-well/how-to-eat-a-balanced-diet/the-vegan-diet/)). [[nutritional-yeast]] is often used to add a savoury, cheese-like flavour and some brands are fortified with B12. A sample day of meals is given in [[meal-planning]]. |
| + |
| + ## Nutrients to plan for |
| − | Vegetables and fruit | A variety of colours, including leafy greens | |
| − | Nuts and seeds | Walnuts, flaxseed, chia, hemp seeds, tahini | |
| − | Fortified foods | Fortified plant milks, breakfast cereals, nutritional yeast | |
| + | Nutrient | Why it matters | Common vegan sources | |
| + |---|---|---| |
| + | [[vitamin-b12]] | Nerves and blood; no reliable unfortified plant source | Supplement or fortified foods (essential) | |
| + | [[vitamin-d]] | Bones and muscles | Sunlight in summer, supplement in winter (D2 or lichen D3), fortified foods | |
| + | [[iodine]] | Thyroid function | Iodised salt or fortified plant milks, or a supplement | |
| + | [[omega-3-fatty-acids]] | Heart, brain and eyes | Ground flaxseed, chia, walnuts, hemp, rapeseed oil; algae oil | |
| + | [[calcium]] | Bones and teeth | Calcium-set tofu, fortified plant milks, tahini, pulses | |
| + | [[iron]] | Oxygen transport | Pulses, wholegrains, fortified cereals, dark leafy greens, with vitamin C | |
| + | [[zinc]] | Immunity and growth | Pulses, nuts, seeds, wholegrains | |
| + | [[protein]] | Growth and repair | Legumes, soya foods, seitan, nuts, seeds, grains | |
| − [[nutritional-yeast]] is often used to add a savoury, cheese-like flavour and some brands are fortified with B12. |
| ## Common challenges |
| People transitioning commonly report the following difficulties: |
| - **Cravings** for particular foods, often cheese. Trying different brands and recipes, or temporarily relying on convenience products, can help. |
| + - **Social pressure** from family, friends or colleagues. Many people find it helpful to focus on sharing food rather than debating. The [itsvegan forums](/forum) are a place to ask others how they managed. |
| − - **Social pressure** from family, friends or colleagues. Many people find it helpful to focus on sharing food rather than debating. |
| - **Digestive changes** from increased fibre, which usually settle as the body adapts. Increasing legumes gradually and cooking them well can reduce discomfort. |
| - **Not eating enough.** Whole plant foods are often less energy-dense, so portions may need to be larger, particularly for active people (see [[vegan-athletes]]). |
| - **Accidental slip-ups.** Mistakes are common when learning, and many vegan organisations encourage people not to be discouraged by them. |
| ## Special circumstances |
| People who are pregnant, breastfeeding, raising children, or living with a medical condition should seek professional dietary guidance. See [[vegan-pregnancy-and-children]] for more detail. |
| + ## Frequently asked questions |
| + |
| + ### What is the easiest way to go vegan? |
| + |
| + For most people, the easiest way is to change one meal at a time, starting with breakfast, while keeping familiar flavours. A fixed trial, such as a 30-day challenge, also works well because it has a clear end point; many people simply continue afterwards. |
| + |
| + ### What do I need to supplement when I go vegan? |
| + |
| + Vitamin B12 is essential for everyone eating a vegan diet. Vitamin D is advised for most people in winter at northern latitudes regardless of diet. Many vegans also consider iodine and an algae-based omega-3 supplement. A doctor or registered dietitian can advise on your own needs. |
| + |
| + ### Should I go vegan gradually or all at once? |
| + |
| + Both approaches work. Gradual change gives you time to learn recipes and shopping habits; switching at once can be simpler for people who prefer clear rules. Choose the one that fits your household and cooking confidence. |
| + |
| + ### Is a vegan diet expensive? |
| + |
| + It does not have to be. Staples such as beans, lentils, oats, rice, pasta, seasonal vegetables and frozen fruit are among the cheapest foods available. Specialist products are optional. See [[vegan-on-a-budget]]. |
| + |
| + ### How do I check whether a food is vegan? |
| + |
| + Read the ingredient list and allergen information for milk, eggs, fish and crustaceans, then look for less obvious ingredients such as gelatin, whey, casein, carmine (E120) and shellac (E904). Our [is it vegan? guide](/is-it-vegan) explains common ingredients and additives one by one. |
