The fitness and bodybuilding world heavily relies on various types of food, protein, and supplements to achieve their fitness goals. Professional bodybuilders, in particular, prioritize these elements as they strive to maintain peak physical condition to compete against one another. While much discussion surrounds the consumption of high-protein foods for bulking, the question arises: which protein source is the most helpful for individuals? Among the basic options are soy, whey, plant, and animal-based protein.
With so many options available, choosing the right protein supplement can end up being confusing. However, there are many distinct differences between whey protein, soy protein, and plant protein. Let us see what they are.

First up, let’s talk about whey protein. Whey protein, derived from milk, is great for building muscles because it’s absorbed quickly by your body. Rich in all essential amino acids, it’s favored for post-workout recovery, promoting muscle growth and repair, and boosting satiety. However, individuals with lactose intolerance or dairy allergies may need to seek alternative options.
Next, there’s soy protein. Extracted from soybeans, it offers a plant-based alternative suitable for vegetarians and vegans. Comparable in quality to whey protein, it contains all essential amino acids. Despite concerns about phytoestrogens and potential hormonal effects, research on this topic remains inconclusive. Soy protein supports muscle maintenance and may aid in lowering cholesterol levels, though some individuals may experience digestive discomfort.
Moreover, there’s plant protein, which can come from peas, rice, hemp, and other plants. While protein content varies depending on the source, many plant proteins are rich in specific amino acids. Although slightly lower in digestibility compared to whey protein, plant proteins remain effective for muscle repair and growth. Moreover, they are suitable for individuals with lactose or soy allergies, and their inclusion in the diet may offer additional health benefits due to the presence of phytonutrients and fiber. However, plant proteins may lack certain essential amino acids, necessitating a varied diet to ensure complete protein intake.
And there’s animal-based protein. Animal-based protein comes from animals like meat, poultry, fish, eggs, and dairy. It has important amino acids that our bodies need for muscles. Many athletes prefer animal protein because it helps muscles grow and heal. Let’s see what experts have to say about various types of protein.
Tim Burmaster warns against a few protein sources
Tim Burmaster, a coach and personal trainer with over 14 years of experience, recently shared some surprising insights about foods many people believe to be healthy. According to him, these foods might seem beneficial but can actually harm the body due to the chemicals they contain.
Burmaster revealed, “Five foods that are often considered healthy but should be completely avoided. Plant-based protein powders, Nuts and nut butter, Nut milk and oat milk, Kale, and Soy.” He went on to explain the potential risks associated with each.
The plant-based protein powders, despite their popularity, can contain heavy metals and are not easily digestible. Similarly, nuts and nut butter, though tasty, may harbor fatty acids, chemicals, and pesticides. Even options, like nut and oat milk, can upset the stomach due to anti-nutrients and gut-upsetting gums. Kale, touted as a superfood, has its drawbacks too, with plant chemicals that can interfere with essential minerals.
Lastly, Burmaster warned against soy, citing digestion issues, pesticide exposure, and hormonal concerns. Instead, he advised opting for alternatives like beef, seafood, raw dairy, eggs, fruit, and honey for better health outcomes. In addition to Burmaster, bodybuilding icon and seven-time Mr. Olympia Arnold Schwarzenegger has discussed animal and plant-based protein in his newsletter.
Arnold Schwarzenegger tries to pitch in amidst the animal vs. plant-based protein debate
Recently, Arnold Schwarzenegger shared his thoughts on plant-based and animal-based protein in his newsletter. Schwarzenegger talked about some interesting research. He explained, “The study was fairly simple: participants were randomly assigned to either an omnivorous or plant-based diet. The scientists made sure the plant-based group ate plant-based protein.”Both groups ate enough protein, including an important amino acid called leucine, which helps muscles grow.
Surprisingly, the study found that both groups gained muscle and got stronger. This challenges the idea that only animal protein is good for building muscles. Schwarzenegger’s advice is simple: just make sure you eat enough protein, whether it’s from plants or animals. According to him, you can get protein from beans, lentils, tofu, and other plant foods. There are also protein supplements like pea protein or soy protein.
What’s important is that you have choices. You can pick the foods you like best, whether they’re from animals or plants. This makes it easier to stay healthy and fit without worrying too much about what you eat.

Professional bodybuilders like Schwarzenegger, Ronnie Coleman, and Jay Cutler advocate for the crucial role of protein in boosting strength and muscle growth. Coleman, known for consuming 6-7 meals daily, and Cutler, who defeated Coleman, share similar opinions. Even during his cheat days, Cutler mixed protein powders to fulfill his protein needs.
The ongoing debate over protein sources for fitness and bodybuilding therefore has no concrete answer. Understanding individual needs and preferences is key to making informed dietary choices for optimal health and performance. What form of protein do you prefer? Let us know in the comments below.
