How to support physical activity on a plant-based diet

Following a plant-based diet can be a fantastic way to support your overall health and wellbeing.

Eating more fruits, vegetables, wholegrains and eating less red meat or processed meat can reduce our risk of developing cardiovascular disease.¹ However, there are a few key nutrients we should take careful consideration of when following a plant-based diet, particularly when it comes to supporting an active lifestyle.

Benefits of a plant-based diet

A well balanced, plant-based diet can have multiple benefits for our health. Fruits, vegetables, and wholegrains all contain fibre, which promotes good gut and bowel health. Consuming a fibre rich diet and engaging in a form of exercise every day is a great way to support your digestive wellbeing.²

Meals that are plant-based can often be less energy dense than meals that contain processed meat (like salami, sausages or ham), which can also help promote a healthy weight when combined with regular exercise. While there are many benefits to following a plant-based diet, there are a few key nutrients that we need to be mindful of not missing out on.

Key nutrients to consider

Vitamin B12 is an important nutrient for nerve function, the formation of red blood cells and cell metabolism and is mostly found in animal products.³ Vitamin B12 is also found in dairy and dairy products, however if you follow a vegetarian diet that does not include dairy, you may be lacking in vitamin B12. Vitamin B12 deficiency can cause symptoms such as fatigue, shortness of breath and lowered exercise tolerance, highlighting the importance of B12 in supporting an active lifestyle.³ If you’re concerned about your vitamin B12 levels, make an appointment with your doctor.

Iron is also an essential nutrient to support an active lifestyle, as it helps transport oxygen to all the cells in our body.⁴ When we become iron deficient, we can often feel fatigued and short of breath. Iron is mostly found in animal foods, so it’s important to ensure we’re eating iron rich plant-based alternatives when following a plant-based diet. Legumes, beans, tofu, nuts, lentils and wholegrains are all great sources of plant-based iron. Plant based sources of iron are not as well absorbed by the body as animal sources but eating these foods with sources of vitamin C can help absorption.

Plant based eating to support exercise

The best way to support exercise on a plant-based diet is to consume a source of plant-based protein at every meal. Aim to eat a meal or snack containing legumes, beans, tofu, nuts, lentils or wholegrains within an hour after exercising, to give your body the best chance of recovery.
