Becoming a vegan requires you to make drastic changes to your diet. You have to eliminate anything of animal origin, which includes meat, seafood, cheese, milk, eggs, fish and gelatin. Vegan diets are naturally low in saturated and trans fats, reducing your risk of developing heart disease and related complications.
On average, vegans consume about .9 g of protein/kg of body weight and obtain 13 percent of their energy from protein (7). Thus, if a vegan eats 18 calories/lb, which is on the lower end for serious weightlifters, he or she will naturally consume 1.3 g of protein/kg of body weight, likely meeting protein needs.
