Keep in mind that it's typically recommended to supplement with higher amounts of vitamin B12 than the Recommended Dietary Allowance (RDA), as your body is only able to absorb a small amount at a time.Try to aim for 2,000–2,500 mcg of vitamin B12 per week. This can be divided into several smaller doses and may require a separate supplement in addition to your multivitamin. You may also want to consider taking algal oil, a plant-based form of omega-3 fatty acid. Your body needs this kind of fat for optimal heart health, brain function, and disease prevention.
In another study, published in the American Journal of Clinical Nutrition in 1999, researchers tracked 45 people: 20 meat-eaters and 25 vegans who had been following the approach for an average of 12 years. Body mass index was appreciably lower among the vegans, nine of whom had a BMI of below 19, the researchers found; a BMI below 18.5 suggests a person is underweight. More than 60 overweight, post-menopausal women were split into two groups: Half followed a vegan diet, and the other half followed a National Cholesterol Education Program diet (low in fat and dietary cholesterol). After a year, vegan dieters lost more weight than did the NCEP group: 10.8 pounds compared with 3.9 pounds. The pattern held up after two years, when the vegans still weighed 6.8 pounds less than they did when the study began, compared with 1.8 pounds for the NCEP group, according to findings published in 2007 in Obesity.
Vegans tend to be thinner and have a lower body mass index (BMI) than non-vegan. This might explain why an increasing number of people turn to vegan diets as a way to lose excess weight.Part of the weight-related benefits vegans experience may be explained by factors other than diet. These may include healthier lifestyle choices, such as physical activity, and other health-related behaviors. However, several randomized controlled studies, which control for these external factors, report that vegan diets are more effective for weight loss than the diets they are compared to.

Industry farmers apply tons of finite resources to run their operations, including fossil fuels, and they also spend millions of dollars on water and cultivate food for those animals.
