I also understand that many people today choose to follow a vegan or vegetarian diet because there’s so much improper treatment of livestock and other animals. While I totally agree that this is sad and common, there are companies that abide by organic and Biblically based standards. If you’re willing to consume high-quality animal proteins in small or moderate amounts, I’d definitely suggest seeking out these types of companies so you can feel good about your source. 

The final possible culprit behind stubborn weight issues may be the stress hormone, cortisol. Too much cortisol will increase hunger levels, bringing along subsequent weight gain. The most common cause of elevated cortisol is chronic stress and lack of sleep (see tip #10), or cortisone medication (tip #9). It’s a good idea to try your best to do something about this.

On average, vegetarians consume a lower proportion of calories from fat (particularly saturated fatty acids), fewer overall calories, more fiber, potassium, and vitamin C, than do non-vegetarians. Vegetarians generally have a lower body mass index. These characteristics and other lifestyle factors associated with a vegetarian diet may contribute to the positive health outcomes that have been identified among vegetarians.

Because plants are low in calories but high in essential vitamins, minerals and antioxidants, vegetarian diets can be very nutrient-dense. Research published in the Proceedings of the Nutrition Society found that “vegetarian diets are usually rich in carbohydrates, omega-6 fatty acids, dietary fiber, carotenoids, folic acid, vitamin C, vitamin E and magnesium, and relatively low in protein, saturated fat, long-chain omega-3 fatty acids, retinol, vitamin B12 and zinc.” (2)

A 2012 study also showed that people on a low-carb diet burned 300 more calories a day – while resting! According to one of the Harvard professors behind the study this advantage “would equal the number of calories typically burned in an hour of moderate-intensity physical activity”. Imagine that: an entire bonus hour of exercise every day, without actually exercising. A later, even larger and more carefully conducted study confirmed the effect, with different groups of people on low-carb diets burning an average of between 200 and almost 500 extra calories per day.
Environmental vegetarianism is based on the concern that the production of meat and animal products for mass consumption, especially through factory farming, is environmentally unsustainable. According to a 2006 United Nations initiative, the livestock industry is one of the largest contributors to environmental degradation worldwide, and modern practices of raising animals for food contribute on a "massive scale" to air and water pollution, land degradation, climate change, and loss of biodiversity. The initiative concluded that "the livestock sector emerges as one of the top two or three most significant contributors to the most serious environmental problems, at every scale from local to global."[207]

Side effects of fasting include dizziness, headaches, low blood sugar, muscle aches, weakness, and fatigue. Prolonged fasting can lead to anemia, a weakened immune system, liver and kidney problems, and irregular heartbeat. Fasting can also result in vitamin and mineral deficiencies, muscle breakdown, and diarrhea. When you drink laxative concoctions during a fast, there is an increased risk of fluid imbalance and dehydration.

To make sure you’re getting enough healthy fats, include at least one of the following in each main meal: nuts and seeds (like almonds, walnuts, hemp, chia or flax), avocado, olive oil, coconut oil or coconut cream/milk, and butter or ghee if you include dairy products. Even if your diet is overall low in fat, try to still get about 20 percent or more of your daily calories from healthy sources of fat.

Western vegetarian diets are typically high in carotenoids, but relatively low in omega-3 fatty acids and vitamin B12.[66] Vegans can have particularly low intake of vitamin B and calcium if they do not eat enough items such as collard greens, leafy greens, tempeh and tofu (soy).[67] High levels of dietary fiber, folic acid, vitamins C and E, and magnesium, and low consumption of saturated fat are all considered to be beneficial aspects of a vegetarian diet.[68] A well planned vegetarian diet will provide all nutrients in a meat-eater's diet to the same level for all stages of life.[69]

Make sure that everything you're eating is whole — as in nothing processed or packaged. Since salt is a preservative, these are the foods that are highest in sodium — something to keep in mind when planning your meals. Plan on making sure that all items you choose are fresh. That means filling up on fresh fruits and veggies, whole grains, low-fat dairy, and lean protein.
Studies on the health effects of vegetarian diets observe heterogeneous effects on mortality. One review found a decreased overall risk of all cause mortality, cancer (except breast) and cardiovascular disease;[47] however, a meta-analysis found lower risk for ischemic heart disease and cancer but no effect on overall mortality or cerebrovascular disease.[48] Possible limitations include varying definitions used of vegetarianism, and the observation of increased risk of lung cancer mortality in those on a vegetarian diet for less than five years.[48] An analysis pooling two large studies found vegetarians in the UK have similar all cause mortality as meat eaters.[49] An older meta analysis found similar results, only finding decreased mortality in vegetarians, pescatarians, and irregular meat eaters in ischemic heart disease, but not from any other cause.[50]
My diet is personally about 70 percent plants and 30 percent animal-derived foods. I usually consume about 70 percent raw plant-based foods, and 30 percent of my diet is organic grass-fed beef, organic pastured dairy, wild-caught fish (wild-caught salmon is my favorite), and free-range organic poultry and eggs. I’ve tried a number of diets, including vegetarian, vegan and pescatarian, and have found I really feel the best following this ratio. I call this ratio the healing foods diet and have also found this to have the best results with my patients, as well. Here’s the new, updated healing foods shopping list so you can have an extensive food guide to follow. If it’s on the list, it’s good to go.
British vegetarians have low mortality compared with the general population. Their death rates are similar to those of comparable non-vegetarians, suggesting that much of this benefit may be attributed to non-dietary lifestyle factors such as a low prevalence of smoking and a generally high socio-economic status, or to aspects of the diet other than the avoidance of meat and fish."[115]
Many people choose to reduce the amount of meat, fish and other animal foods in their diets in order to lower their carbon footprints. Plant foods are “lower on the food chain” and require less natural resources, such as water and others, to produce. According to a report in the American Journal of Clinical Nutrition, manufacturing animal foods requires a higher proportion of water, land, fossil fuels and energy than most plant foods do. (7)
Similar to environmental vegetarianism is the concept of economic vegetarianism. An economic vegetarian is someone who practices vegetarianism from either the philosophical viewpoint concerning issues such as public health and curbing world starvation, the belief that the consumption of meat is economically unsound, part of a conscious simple living strategy or just out of necessity. According to the Worldwatch Institute, "Massive reductions in meat consumption in industrial nations will ease their health care burden while improving public health; declining livestock herds will take pressure off rangelands and grainlands, allowing the agricultural resource base to rejuvenate. As populations grow, lowering meat consumption worldwide will allow more efficient use of declining per capita land and water resources, while at the same time making grain more affordable to the world's chronically hungry."[220]
According to research published by the Department of Nutrition, School of Public Health at Loma Linda University, people who follow a vegetarian diet or vegan diet — meaning they avoid all meat and possibly dairy, fish and eggs too — represent between 2 percent to 5 percent of the total adult population in the United States. (1) Several analyses that have compared vegetarian diets to non-vegetarian diets have found that those eating predominately plant-based diets have increased protection against health problems, including cardiovascular diseases, cardiometabolic risk factors, some cancers, type 2 diabetes, obesity and total mortality.
Plant-based, or vegetarian, sources of Omega 3 fatty acids include soy, walnuts, pumpkin seeds, canola oil, kiwifruit, hempseed, algae, chia seed, flaxseed, echium seed and leafy vegetables such as lettuce, spinach, cabbage and purslane. Purslane contains more Omega 3 than any other known leafy green. Olives (and olive oil) are another important plant source of unsaturated fatty acids. Plant foods can provide alpha-linolenic acid which the human body uses to synthesize the long-chain n-3 fatty acids EPA and DHA. EPA and DHA can be obtained directly in high amounts from oily fish or fish oils. Vegetarians, and particularly vegans, have lower levels of EPA and DHA than meat-eaters. While the health effects of low levels of EPA and DHA are unknown, it is unlikely that supplementation with alpha-linolenic acid will significantly increase levels.[95][clarification needed] Recently, some companies have begun to market vegetarian DHA supplements containing seaweed extracts. Whole seaweeds are not suitable for supplementation because their high iodine content limits the amount that may be safely consumed. However, certain algae such as spirulina are good sources of gamma-linolenic acid (GLA), alpha-linolenic acid (ALA), linoleic acid (LA), stearidonic acid (SDA), eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), and arachidonic acid (AA).[96][97]

In May 2009, Ghent, Belgium, was reported to be "the first [city] in the world to go vegetarian at least once a week" for environmental reasons, when local authorities decided to implement a "weekly meatless day". Civil servants would eat vegetarian meals one day per week, in recognition of the United Nations' report. Posters were put up by local authorities to encourage the population to take part on vegetarian days, and "veggie street maps" were printed to highlight vegetarian restaurants. In September 2009, schools in Ghent are due to have a weekly veggiedag ("vegetarian day") too.[212]
 'Kosher Gelatin Marshmallows: Glatt Kosher and "OU-Pareve",' an article that appeared in Kashrus Magazine, explains the distinctions. A quote from the article is as follows: '...since the gelatin product is from hides or bones—not real flesh—and has undergone such significant changes, it is no longer considered 'fleishig' (meat) but 'pareve', and can be eaten with dairy products.' [...] Rennet is like gelatin in the sense that it's a common food additive but the foods containing it are often considered vegetarian.
