Introduction
The vegan diet has recently become popular for many reasons, such as they find it ethical, they want to ‘go green,’ for health reasons and through celebrity influences.1 The diet only consists of plants such as vegetables, nuts, grains, and fruits, cutting out any animal-based products such as meat, fish, milk, and eggs.2 Meal planning is important for weight loss as it allows you to see how much you are eating, and prevents you from overeating.3 This article will explore the vegan diet and understand how this can lead to weight loss.
Understanding veganism and weight loss
The vegan society defines veganism as:4
"Veganism is a philosophy and way of living which 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; and by extension, promotes the development and use of animal-free alternatives for the benefit of animals, humans and the environment. In dietary terms, it denotes the practice of dispensing with all products derived wholly or partly from animals."
Veganism dates back to 1944 when a small group of vegetarians formed a group known as the Vegan Society.
There are many ways to uphold a healthy vegan diet such as:1
- Eat at least 5 portions of fruit and vegetables each day
- Eat mostly starchy carbohydrates such as bread, rice, pasta, and potatoes to be filled up for longer
- Consume dairy alternatives such as soya milk and soya yoghurts
- Eating proteins such as beans and pulses
- Eating food rich in omega-3 fatty acids like nuts, seeds, and walnuts each day
- Eating unsaturated oils in small amounts
- Eating supplements which would be difficult to get from a vegan diet such as vitamin D, vitamin B12, iodine, calcium, iron, and selenium
- Drink 6 to 8 cups of fluids a day
The vegan diet can lead to weight loss in 3 ways:5
- Increased fibre: the vegan diet is full of whole grains, vegetables, and fruits rich in fibre. This component is important for gut health and filling you up, expanding your stomach and making you feel fuller for longer. This can reduce calorie intake, reducing weight
- Reduced calorie intake: plant-based food has a lower calorie content compared to meat, eggs, saturated fats, and dairy. Fruits and vegetables are packed with vitamins and minerals, while also containing a low-calorie content
- Gut health: recent studies show an imbalance of negative and positive gut bacteria is associated with a greater risk of weight gain. The vegan diet contains a variety of plant foods and fibre, feeding the positive bacteria in the gut
Tips for success
There are many factors to take into consideration when designing a vegan meal plan this includes:
- Setting realistic weight loss goals: it is important not to get burnt out when going on a diet and going straight into any type of diet can be harmful to health. It is important to ease into diets and know your body's strengths and weaknesses
- Determining daily calorie needs: it is important to plan your meal plan around how many calories your body needs. Ideally, the recommended daily calorie intake for women is 2,000 calories and 2,500 for men.6 However, this varies depending on age, lifestyle, size, hormones, medicines and being unwell. Please consult your doctor if you are unsure about your calorie intake
- Macronutrient distribution: this refers to the 3 main components in every diet, carbohydrates, fats, and proteins. These are important for healthy growth and development, influencing: how full you feel, metabolic rate, appetite hormones and muscle recovery. It is recommended to consume 10-35% protein (18+), 20-35% fat and 45-65% carbohydrates for weight loss7
- Importance of portion control: research shows when offered larger potions, people are tempted to eat more food.8 This is why meal planning is important for weight loss as it allows you to plan, view and execute the right amount of food so you do not overeat and gain weight
- Incorporating whole foods and avoiding processed products: refined sugar does not give you the same satisfaction as whole foods. As it makes you feel constantly hungry, you make you overeat the wrong type of food, whereas whole food makes you full for longer
These factors are important to consider when undertaking a vegan diet and should be carefully thought about before following through.

- Social pressures – it may be hard to overcome social pressures but surrounding yourself with other people with the same goal and diet as yourself can be the motivation you need to carry on and make a life-changing decision
