Dr. Mike Goes Vegan
In a Nutshell
Dr. Mike completed a one-day vegan diet challenge while maintaining his bodybuilding macros, replacing all animal products with plant-based alternatives like fermented whey protein, vegetarian burgers, and Abbott's chicken. The experiment hit nearly identical macros (2,854 calories, 296g protein) compared to his normal 2,950-calorie diet with 315g protein, though the vegan version cost significantly more. He found the experience surprisingly positive with modern plant-based options, concluding vegan bodybuilding is practical but expensive.

Dr. Mike is beginning a one-day vegan diet challenge while maintaining his bodybuilding training and macros. He will consume the same calories and protein targets but replace all animal products with plant-based alternatives. The experiment will test cost, practicality, taste, and effectiveness.
Gatorade is confirmed as vegan and will remain in the protocol. The workout drink includes 30-35 grams of Gatorade plus non-animal whey protein from My Protein. Two scoops provide 40 grams of protein, with half a scoop contributing 35 grams of carbohydrates, totaling approximately 325 calories with almost no fat. This serves as the first meal during leg training.
The non-animal whey is created through fermentation rather than animal sources. Dr. Mike emphasizes that governing bodies recommend protein supplements for vegetarians, and this product provides 20 grams of protein, 2 grams of carbohydrates, and zero fat per serving. The plan involves adding 1-1.5 scoops (sometimes 2 scoops) to every meal to reach 300 grams of daily protein without animal products.
Dr. Mike proceeds to the gym for an intense leg workout after consuming the vegan pre-workout shake. The shake has a distinctive smell described as similar to a pet store, but the taste is acceptable.
The second meal replaces a typical Chipotle order of triple chicken, white rice, and black beans. Instead, the meal consists of 217.5 grams of beef substitute, apples for carbohydrates, 250 grams of broccoli, and non-animal whey protein. The macro breakdown targets 80 grams of protein, 85 grams of carbohydrates, and 5 grams of fat. The meal contains about 150 fewer calories than usual, with the difference to be added to later meals.
Preparation involves weighing ingredients precisely using a food scale. The broccoli is microwaved, and Dr. Mike notes that each small piece weighs approximately 15 grams. The meal is described as nutritious with a color resembling internal body fluids.
Dr. Mike emphasizes the benefits of fresh fruit, noting apples are low in calories, high in fiber, fluids, and micronutrients. The beef substitute and broccoli combination tastes good, with the beef alternative having a flavor similar to plant protein rather than actual beef. He commits to finishing the entire meal.
The third meal replaces 80 grams of protein from minced bison, 25 grams of fat, and 115 grams of carbohydrates from vegetables and white rice. Instead, two vegetarian burgers are microwaved, supplemented with non-animal whey protein, 100 grams of baby carrots, and 120 grams of fresh pineapple. The meal provides 72 grams of protein, 52 grams of carbohydrates, and 28 grams of fat. The burgers contain more fat than the original bison meal.
Dr. Mike notes that vegetarians in the late 1990s had limited options and had to prepare most food themselves, contrasting with current availability of convenient plant-based alternatives.
Dr. Mike performs cardio outdoors to reach his daily 10,000-step goal, walking in a parking garage near luxury vehicles including a Lamborghini.
The fourth meal includes a full-size sweet potato, Abbott's vegetarian sliced chicken, 1.5 servings of non-animal whey protein, and 300 grams of strawberries. The meal provides 77 grams of protein, 68 grams of carbohydrates, and 10 grams of fat. Dr. Mike tries strawberries for the first time on camera and finds them amazing. The sweet potato from a microwavable bag and the vegetarian chicken are both well-received, with good texture and no strange aftertaste.
The final meal consists of bananas, vegan Barbells protein bars, and whey pudding made with half a scoop of non-animal whey mixed with two shots of vodka. The meal provides 27 grams of protein, 73 grams of carbohydrates, and 11 grams of fat.
Daily comparison:
- Original diet: 2950 calories, 315 grams protein, 70 grams fat, 265 grams carbohydrates
- Vegan day: 2854 calories, 296 grams protein, 54 grams fat, with higher carbohydrates
The vegan day resulted in 100 fewer calories and approximately the same protein intake. Protein quality is slightly lower due to plant-based alternatives, with an estimated 250 grams of high-quality protein actually utilized by muscles. The cost was significantly higher due to premium plant-based products and fresh produce, though bulk purchasing could reduce expenses.
Dr. Mike concludes the experiment was successful in meeting nutritional targets and finds the experience positive overall, noting the current availability of high-quality vegetarian options compared to previous decades.
