According to Genesis, consumption of meat was prohibited to human beings (1:29-30) though Noah was given permission to consume meat after the Great Flood. Some advocates of Jewish vegetarianism, such as Rabbi Abraham Isaac Kook, describe vegetarianism as an eschatological ideal to which all human beings must eventually return.[188] A number of Jewish vegetarian groups and activists promote such ideas and believe that the halakhic permission to eat meat is a temporary leniency for those who are not ready yet to accept the vegetarian diet.[189] For some commentators, such as Rabbi Shlomo Ephraim Luntschitz, the complexity of the laws of sacrifice and slaughter (shechita) was intended to discourage the consumption of meat and make it less painful for the animals.[190]

Many vegetarians don't consider that some of the cheeses they are eating could actually contain unfamiliar animal ingredients. That's right cheese, a common staple in many vegetarian diets, is often made with rennet or rennin, which is used to coagulate the dairy product.
A number of medieval rabbis (e.g., Joseph Albo and Isaac Arama) regard vegetarianism as a moral ideal because the slaughter of animals might cause the individual who performs such acts to develop negative character traits. Many modern rabbis, by contrast, advocate vegetarianism or veganism primarily because of concerns about animal welfare, especially in light of the traditional prohibition on causing unnecessary "pain to living creatures" (tza'ar ba'alei hayyim).[187] 

Since the formation of the Seventh-day Adventist Church in the 1860s when the church began, wholeness and health have been an emphasis of the Adventist church, and has been known as the "health message" belief of the church.[164] Adventists are well known for presenting a health message that recommends vegetarianism and expects adherence to the kosher laws in Leviticus 11. Obedience to these laws means abstinence from pork, shellfish, and other animals proscribed as "unclean". The church discourages its members from consuming alcoholic beverages, tobacco or illegal drugs (compare Christianity and alcohol). In addition, some Adventists avoid coffee, tea, cola, and other beverages containing caffeine.
If you want to lose weight, you’d better avoid special “low-carb” products that are full of carbs. This should be obvious, but creative marketers are doing all they can to fool you (and get your money). They will tell you that you can eat cookies, pasta, ice cream, bread and plenty of chocolate on a low-carb diet, as long as you buy their brand. They’re full of carbohydrates. Don’t be fooled.
In addition, animal agriculture is a large source of greenhouse gases. According to a 2006 report it is responsible for 18% of the world's greenhouse gas emissions as estimated in 100-year CO2 equivalents. Livestock sources (including enteric fermentation and manure) account for about 3.1 percent of US anthropogenic GHG emissions expressed as carbon dioxide equivalents.[208] This EPA estimate is based on methodologies agreed to by the Conference of Parties of the UNFCCC, with 100-year global warming potentials from the IPCC Second Assessment Report used in estimating GHG emissions as carbon dioxide equivalents.
There is some scientific legitimacy to today’s lower-carb diets: Large amounts of simple carbohydrates from white flour and added sugar can wreak havoc on your blood sugar and lead to weight gain. While avoiding sugar, white rice, and white flour, however, you should eat plenty of whole-grain breads and brown rice. One Harvard study of 74,000 women found that those who ate more than two daily servings of whole grains were 49 percent less likely to be overweight than those who ate the white stuff. Eating whole grains is not only one of many great ways to lose weight; it can also make you smarter.

It's a one-time investment you'll never regret. Here's why: Strength training builds lean muscle tissue, which burns more calories — at work or at rest — 24 hours a day, seven days a week. The more lean muscle you have, the faster you'll slim down. How do you start strength training? Try some push-ups or a few squats or lunges. Use your free weights to perform simple bicep curls or tricep pulls right in your home or office. Do these exercises three to four times per week, and you'll soon see a rapid improvement in your physique.
Plain and simple: We just don't feel full by liquid calories in quite the same way as we do real food. Drinking a juice or caramel coffee drink, for instance, won't make you feel full the way eating a bowl of veggie- and protein-packed stir-fry will. So monitor your intake of juice, soda, sweetened coffee and tea, and alcoholic beverages. If you consume each of those beverages during the day, you'll have taken in at least 800 extra calories by nighttime — and you'll still be hungry. (Incidentally, alcohol may suppress the metabolism of fat, making it tougher for you to burn those calories.) Some other ways to skip sugar? Check 'em out here.
The trick here is not only to avoid all obvious sources of carbohydrate (sweets, bread, spaghetti, rice, potatoes), but also to be careful with your protein intake. If you eat large amounts of meat, eggs and the like, the excess protein will be converted into glucose in your body. Large amounts of protein can also raise your insulin levels somewhat. This compromises optimal ketosis.
A study by the Institute of Preventive and Clinical Medicine, and Institute of Physiological Chemistry looked at a group of 19 vegetarians (lacto-ovo) and used as a comparison a group of 19 omnivorous subjects recruited from the same region. The study found that this group of vegetarians (lacto-ovo) have a significantly higher amount of plasma carboxymethyllysine and advanced glycation endproducts (AGEs) compared to this group of non-vegetarians.[119] Carboxymethyllysine is a glycation product which represents "a general marker of oxidative stress and long-term damage of proteins in aging, atherosclerosis and diabetes" and "[a]dvanced glycation end products (AGEs) may play an important adverse role in process of atherosclerosis, diabetes, aging and chronic renal failure".[119]
Vegetarianism may be adopted for various reasons. Many people object to eating meat out of respect for sentient life. Such ethical motivations have been codified under various religious beliefs, as well as animal rights advocacy. Other motivations for vegetarianism are health-related, political, environmental, cultural, aesthetic, economic, or personal preference. There are variations of the diet as well: an ovo-lacto vegetarian diet includes both eggs and dairy products, an ovo-vegetarian diet includes eggs but not dairy products, and a lacto-vegetarian diet includes dairy products but not eggs. A vegan diet excludes all animal products, including eggs and dairy. Some vegans also avoid other animal products such as beeswax, leather or silk clothing, and goose-fat shoe polish.
While there are no dietary restrictions in the Bahá'í Faith, `Abdu'l-Bahá, the son of the religion's founder, noted that a vegetarian diet consisting of fruits and grains was desirable, except for people with a weak constitution or those that are sick.[136] He stated that there are no requirements that Bahá'ís become vegetarian, but that a future society should gradually become vegetarian.[136][137][138] `Abdu'l-Bahá also stated that killing animals was contrary to compassion.[136] While Shoghi Effendi, the head of the Bahá'í Faith in the first half of the 20th century, stated that a purely vegetarian diet would be preferable since it avoided killing animals,[139] both he and the Universal House of Justice, the governing body of the Bahá'ís have stated that these teachings do not constitute a Bahá'í practice and that Bahá'ís can choose to eat whatever they wish but should be respectful of others' beliefs.[136]
Followers of Jainism believe that all living organisms whether they are micro-organism are living and have a soul, and have one or more senses out of five senses and they go to great lengths to minimise any harm to any living organism. Most Jains are lacto-vegetarians but more devout Jains do not eat root vegetables because they believe that root vegetables contain a lot more micro-organisms as compared to other vegetables, and that, by eating them, violence of these micro-organisms is inevitable. So they focus on eating beans and fruits, whose cultivation do not involve killing of a lot of micro-organisms. No products obtained from dead animals are allowed, because when a living beings dies, a lot of micro-organisms (called as decomposers) will reproduce in the body which decomposes the body, and in eating the dead bodies, violence of decomposers is inevitable. Jain monks usually do a lot of fasting, and when they knew through spiritual powers that their life is very little, they start fasting until death.[180][181] Some particularly dedicated individuals are fruitarians.[182] Honey is forbidden, because honey is the regurgitation of nectar by bees [183] and may also contain eggs, excreta and dead bees. Some Jains do not consume plant parts that grow underground such as roots and bulbs, because the plants themselves and tiny animals may be killed when the plants are pulled up.[184]
Obviously, it’s still possible to lose weight on any diet – just eat fewer calories than you burn, right? The problem with this simplistic advice is that it ignores the elephant in the room: Hunger. Most people don’t like to “just eat less”, i.e. being hungry forever. That’s dieting for masochists. Sooner or later, a normal person will give up and eat, hence the prevalence of “yo-yo dieting”.
Other diabetes medications. Insulin-releasing tablets (e.g. sulphonylureas) often lead to weight gain. These include: Minodiab, Euglucon, Daonil, and Glibenclamide. Tablets like Avandia, Actos, Starlix and NovoNorm also encourage weight gain. But not Metformin. The newer drugs Victoza and Byetta (injectable) often lead to weight loss, but possible long-term side effects are still unknown. More on diabetes

Jainism teaches vegetarianism as moral conduct as do some major[130] sects of Hinduism. Buddhism in general does not prohibit meat eating, while Mahayana Buddhism encourages vegetarianism as beneficial for developing compassion.[131] Other denominations that advocate a vegetarian diet include the Seventh-day Adventists, the Rastafari movement, the Ananda Marga movement and the Hare Krishnas. Sikhism[132][133][134] does not equate spirituality with diet and does not specify a vegetarian or meat diet.[135]
Keep in mind that the initial weight lost on a fast is primarily fluid or "water weight," not fat. And when you go back to eating, any lost weight usually gets a return ticket back. Not only do most people regain weight lost on a fast, they tend to add a few extra pounds because a slower metabolism makes it easier to gain weight. Worse, the weight that is regained is likely to be all fat -- lost muscle has to be added back at the gym.

Following the Christianization of the Roman Empire in late antiquity, vegetarianism practically disappeared from Europe, as it did elsewhere, except in India.[34] Several orders of monks in medieval Europe restricted or banned the consumption of meat for ascetic reasons, but none of them eschewed fish.[35] Moreover, the medieval definition of "fish" included such animals as seals, porpoises, dolphins, barnacle geese, puffins, and beavers.[36] Vegetarianism re-emerged during the Renaissance,[37] becoming more widespread in the 19th and 20th centuries. In 1847, the first Vegetarian Society was founded in the United Kingdom;[38] Germany, the Netherlands, and other countries followed. In 1886, the vegetarian colony Nueva Germania was founded in Paraguay, though its vegetarian aspect would prove short-lived.[39]:345–358 The International Vegetarian Union, an association of the national societies, was founded in 1908. In the Western world, the popularity of vegetarianism grew during the 20th century as a result of nutritional, ethical, and—more recently—environmental and economic concerns.
Basically, the effect of exercise on our weight is vastly overrated. That’s why it’s only number 15 on this list. There are other things you need to take care of first. It’s not a good idea to eat bad food, drink sugar water (so-called “sports drinks”) or be on medications which force you to exercise for hours daily just to compensate. Metaphorically that’s like digging a hole, into which you put your ladder, on which you stand and paint the basement-level windows of your house.
All meals are important, but breakfast is what helps you start your day on the right track. The best, heartiest breakfasts are ones that will fill you up, keep you satisfied, and stave off cravings later in the day. Aim to eat anywhere between 400 and 500 calories for your morning meal, and make sure you're including a source of lean protein plus filling fat (e.g., eggs, beans, unsweetened Greek yogurt, nuts, or nut butters) and fiber (veggies, fruit, or 100% whole grains). Starting your day with a blood sugar-stabilizing blend of nutrients will help you slim down without sacrifice.
It’s stunning how often we eat out of boredom, nervousness, habit, or frustration—so often, in fact, that many of us have actually forgotten what physical hunger feels like. If you’re hankering for a specific food, it’s probably a craving, not hunger. If you’d eat anything you could get your hands on, chances are you’re truly hungry. Learn how to recognize these feelings mistaken for hunger, then find ways other than eating to express love, tame stress, and relieve boredom. But talk to your doctor if you think you’re always hungry for a medical reason. Here are 10 medical reasons you might be hungry.
Individuals sometimes label themselves "vegetarian" while practicing a semi-vegetarian diet,[9][42][43] as some dictionary definitions describe vegetarianism as sometimes including the consumption of fish,[8] or only include mammalian flesh as part of their definition of meat,[8][44] while other definitions exclude fish and all animal flesh.[11] In other cases, individuals may describe themselves as "flexitarian".[42][45] These diets may be followed by those who reduce animal flesh consumed as a way of transitioning to a complete vegetarian diet or for health, ethical, environmental, or other reasons. Semi-vegetarian diets include:
According to Canon Law, Roman Catholics ages 14 and older are required to abstain from meat (defined as all mammal and fowl flesh and organs, excluding water animals) on Ash Wednesday and all Fridays of Lent including Good Friday. Canon Law also obliges Catholics to abstain from meat on the Fridays of the year outside of Lent (excluding certain holy days) unless, with the permission of the local conference of bishops, another penitential act is substituted. The restrictions on eating meat on these days is solely as an act of penance and not because of a religious objection to eating meat.[163]
Early Christians disagreed as to whether they should eat meat, and later Christian historians have disagreed over whether Jesus was a vegetarian.[149][150][151] Various groups within Christianity have practiced specific dietary restrictions for various reasons.[152] The Council of Jerusalem in around 50 AD, recommended Christians keep following some of the Jewish food laws concerning meat. The early sect known as the Ebionites are considered to have practiced vegetarianism. Surviving fragments from their Gospel indicate their belief that – as Christ is the Passover sacrifice and eating the Passover lamb is no longer required – a vegetarian diet may (or should) be observed. However, orthodox Christianity does not accept their teaching as authentic. Indeed, their specific injunction to strict vegetarianism was cited as one of the Ebionites' "errors".[153][154]

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]

Nuts, the second food to watch, contain a fair amount of carbohydrate, and it’s very easy to unwittingly scarf down large quantities. Cashew nuts are among the worst carb-wise – you’ll find that they contain around 20% carbohydrate by weight. For someone following a strict keto diet with a 20 grams of carbs per day allowance, this means that consuming 100 grams (which happens in a flash!) will have filled their daily quota. Peanuts tend to be around 10-15% carbohydrate – not putting them in the clear either.
When meat is cooked at high temperatures, certain chemical compounds called heterocyclic amines can be created that may have carcinogenic effects. Recently published research has pointed to a link between consumption of highly processed meat products and higher risk for cancer. The higher the cooking temperature of meat, the greater chance of these byproducts being created.
The sad truth is that conventional ideas – eat less, run more – do not work long term. Counting calories, exercising for hours every day and trying to ignore your hunger? That’s needless suffering and it wastes your time and precious willpower. It’s weight loss for masochists. Eventually almost everyone gives up. That’s why we have an obesity epidemic. Fortunately there’s a better way.
Ethical vegetarianism has become popular in developed countries particularly because of the spread of factory farming, faster communications, and environmental consciousness. Some believe that the current mass demand for meat cannot be satisfied without a mass-production system that disregards the welfare of animals, while others believe that practices like well-managed free-ranging and consumption of game, particularly from species whose natural predators have been significantly eliminated, could substantially alleviate the demand for mass-produced meat.[citation needed]
Overconsumption of carbohydrates — One of the most common trends I’ve found from working with hundreds of vegans and vegetarians is that they tend to overconsume carbohydrates and sugars. Eating too many carbs can cause candida and yeast overgrowth, along with weight gain. There are some who have been able to find better balance, but this can take a lot of work and planning.

If you choose to include a good amount raw foods in your diet, you’ll benefit from obtaining higher amounts of enzymes that serve many purposes. When cooked over a certain temperature, enzymes found in raw food often become destabilized. Enzymes are important because they are needed to break down the food into smaller nutritional units that the body can handle.
