A nutritionist’s guide to protein on a plant-based diet, including plant-based alternatives and expert tips
A vegan sports nutritionist has shared advice on how people following a plant-based diet can still meet their protein needs, countering the perception that plant-based eating makes it harder to build muscle. TJ Waterfall, author of "The Plant-Based Power Plan" and an adviser to Olympic athletes and Premier League footballers, argues that plant protein can build muscle just as effectively as animal protein when consumed in sufficient quantities, and that the main mistake people make is failing to properly replace meat with plant-based alternatives in meals.
Waterfall recommends swapping meat for protein-rich foods such as chickpeas, lentils, tofu, tempeh, edamame and soy milk, describing it as a simple substitution that preserves protein intake. He also highlights fibre as an overlooked issue, noting that over 90% of UK adults fail to meet the recommended 30g daily intake, and points to plant-based diets' antioxidant content as beneficial for muscle recovery after exercise. He suggests practical meals, such as porridge with soy milk, berries, flax seeds and nut butter, to combine protein with recovery-boosting nutrients.
In short
- Vegan nutritionist TJ Waterfall says plant-based diets can meet protein needs
- Key swaps: chickpeas, lentils, tofu, tempeh, edamame, soy milk
- Over 90% of UK adults don't get enough daily fibre
Steelman: both sides, in good faith
The strongest fair case each way — we don't pick a winner.
The case for
Plant-based diets effectively supply all necessary amino acids for muscle development when based on adequate quantities of varied sources including legumes, soy products, grains and nuts. Plant-based eating provides additional nutritional benefits through substantially higher fibre and antioxidant content that support athletic recovery and overall health, and with practical meal planning, meeting protein needs is entirely achievable.
The case against
Whilst plant-based diets can meet protein requirements, they demand substantially greater nutritional knowledge and planning than this guidance acknowledges. Individual plant proteins lack complete essential amino acids and require deliberate food combining to ensure adequacy, critical supplementation like B12 is overlooked, and for most people without nutrition expertise, animal-based proteins' superior bioavailability and amino acid completeness make meeting athletic protein needs more straightforward.
Explained simply
Plant-based diets are becoming increasingly common, with people choosing them for various reasons. However, a widespread concern is whether avoiding animal products makes it difficult to eat enough protein to support muscle growth and athletic performance, leading many to question whether plant-based eating suits those with serious fitness goals.
TJ Waterfall is a vegan sports nutritionist and author who works with Olympic athletes and Premier League footballers. His expertise and professional experience bring credibility to discussions about plant-based nutrition and performance.
The topic matters because many people are uncertain whether they can meet their nutritional needs without animal products, leaving a gap between what is possible and what people believe to be possible. Clear information from qualified sports nutrition experts can help people make informed dietary choices, whether they are pursuing plant-based eating for ethical reasons or seeking better health and fitness outcomes.
