Seventh-day Adventists are encouraged to engage in healthy eating practices, and ova-lacto-vegetarian diets are recommended by the General Conference of Seventh-day Adventists Nutrition Council (GCNC). They have also sponsored and participated in many scientific studies exploring the impact of dietary decisions upon health outcomes.[158] The GCNC has in addition adapted the USDA's food pyramid for a vegetarian dietary approach.[158][159] However, the only kinds of meat specifically frowned upon by the SDA health message are unclean meats, or those forbidden in scripture.[160]
Vitamin D2, or ergocalciferol is found in fungus (except alfalfa which is a plantae) and created from viosterol, which in turn is created when ultraviolet light activates ergosterol (which is found in fungi and named as a sterol from ergot). Any UV-irradiated fungus including yeast form vitamin D2.[107] Human bioavailability of vitamin D2 from vitamin D2-enhanced button mushrooms via UV-B irradiation is effective in improving vitamin D status and not different from a vitamin D2 supplement according to study.[108] For example, Vitamin D2 from UV-irradiated yeast baked into bread is bioavailable.[109] By visual assessment or using a chromometer, no significant discoloration of irradiated mushrooms, as measured by the degree of "whiteness", was observed[110] making it hard to discover if they have been treated without labeling. Claims have been made that a normal serving (approx. 3 oz or 1/2 cup, or 60 grams) of mushrooms treated with ultraviolet light increase their vitamin D content to levels up to 80 micrograms,[111] or 2700 IU if exposed to just 5 minutes of UV light after being harvested.[112]

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.

Princeton University professor and animal rights activist Peter Singer believes that if alternative means of survival exist, one ought to choose the option that does not cause unnecessary harm to animals. Most ethical vegetarians argue that the same reasons exist against killing animals in the flesh to eat as against killing humans to eat, especially humans with cognitive abilities equal or lesser than the animals in question. Singer, in his book Animal Liberation, listed possible qualities of sentience in non-human creatures that gave such creatures the scope to be considered under utilitarian ethics, and this has been widely referenced by animal rights campaigners and vegetarians. Ethical vegetarians also believe that killing an animal, like killing a human, especially one who has equal or lesser cognitive abilities than the animals in question, can only be justified in extreme circumstances and that consuming a living creature for its enjoyable taste, convenience, or nutrition value is not a sufficient cause. Another common view is that humans are morally conscious of their behavior in a way other animals are not, and therefore subject to higher standards.[123] One author proposes that denying the right to life and humane treatment to animals with equal or greater cognitive abilities than mentally disabled humans is an arbitrary and discriminatory practice based on habit instead of logic.[124] Opponents of ethical vegetarianism argue that animals are not moral equals to humans and so consider the comparison of eating livestock with killing people to be fallacious. This view does not excuse cruelty, but maintains that animals do not possess the rights a human has.[125]

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:


Similarly, children under age 5 who are reared on vegetarian and vegan diets can suffer impaired growth. That's because of the potential for a vitamin B12 deficiency, which can also result in anemia and vitamin D deficiency which can cause rickets. DHA, an omega-3 fatty acid found mostly in fish, is important for optimal brain development the first 2 years of life. Consult a registered dietitian who can help design a well-planned diet that can meet all the nutritional needs.
You already know that a perfect diet doesn't exist, but many of us still can't resist the urge to kick ourselves when we indulge, eat too much, or get thrown off course from restrictive diets. The problem: This only makes it more difficult, stressful, and downright impossible to lose weight. So rather than beating yourself up for eating foods you think you shouldn't, let it go. Treating yourself to about 200 calories worth of deliciousness each day — something that feels indulgent to you — can help you stay on track for the long-haul, so allow yourself to eat, breathe, and indulge. Food should be joyful, not agonizing!
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]
To get the most out of a vegetarian diet, choose a variety of healthy plant-based foods, such as whole fruits and vegetables, legumes and nuts, and whole grains. At the same time, cut back on less healthy choices, such as sugar-sweetened beverages, fruit juices and refined grains. If you need help, a registered dietitian can assist you in creating a vegetarian plan that's right for you.
Cortisone as an oral drug is another common culprit (e.g. Prednisolone). Cortisone often causes weight gain in the long run, especially at higher doses (e.g. more than 5 mg Prednisolone per day). Unfortunately, cortisone is often an essential medication for those who are prescribed it, but the dose should be adjusted frequently so you don’t take more than you need. Asthma inhalers and other local cortisone treatments, like creams or nose sprays, hardly affect weight.
Breaking the fast is one of the most important elements of the fast . Although what you do during the fast is of course important, it is what you do afterwards that is critical. In fact, the benefits of a fast depend upon the dietetic management after it is broken. The longer the fast, the more care must be taken in breaking it. Breaking an extended fast can be difficult and can be harder than fasting. A slumbering digestive system is sensitive, and although you might want to try every food on the planet, you cannot because your system needs time to get back to speed.

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]
Instead of piling everything on one plate, bring food to the table in individual courses. For the first two courses, bring out soup or veggies such as a green salad or the most filling fruits and vegetables. By the time you get to the more calorie-dense foods, like meat and dessert, you’ll be eating less or may already be full. Nothing wrong with leftovers!

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.
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]
Chronic stress may increase levels of stress hormones such as cortisol in your body. This can cause increased hunger and result in weight gain. If you’re looking to lose weight, you should review possible ways to decrease or better handle excessive stress in your life. Although this often demands substantial changes, even altering small things – such as posture – may immediately affect your stress hormone levels, and perhaps your weight.
Most people who want to lose weight have more than 12 pounds to lose. That’s why even the best weight loss drug in the world can only be an optional complement to other treatment. That’s why this piece of advice is number 18 out of 18. It may be a helpful addition for some people, but the advice higher on the list is what can make the biggest difference, by far.

"When going out for fast food, I used to get the large-size value meal. Now, I satisfy a craving by ordering just one item: a small order of fries or a six-piece box of chicken nuggets. So far, I've shaved off 16 pounds in seven weeks, and I'm on track to being thinner than my high school self for my 10-year reunion later this year." —Miranda Jarrell, Birmingham, AL
Vegetarian diets typically contain similar levels of iron to non-vegetarian diets, but this has lower bioavailability than iron from meat sources, and its absorption can sometimes be inhibited by other dietary constituents.[81] According to the Vegetarian Resource Group, consuming food that contains vitamin C, such as citrus fruit or juices, tomatoes, or broccoli, is a good way to increase the amount of iron absorbed at a meal.[82] Vegetarian foods rich in iron include black beans, cashews, hempseed, kidney beans, broccoli, lentils, oatmeal, raisins, spinach, cabbage, lettuce, black-eyed peas, soybeans, many breakfast cereals, sunflower seeds, chickpeas, tomato juice, tempeh, molasses, thyme, and whole-wheat bread.[83] The related vegan diets can often be higher in iron than vegetarian diets, because dairy products are low in iron.[68] Iron stores often tend to be lower in vegetarians than non-vegetarians, and a few small studies report very high rates of iron deficiency (up to 40%,[84] and 58%[85] of the respective vegetarian or vegan groups). However, the American Dietetic Association states that iron deficiency is no more common in vegetarians than non-vegetarians (adult males are rarely iron deficient); iron deficiency anaemia is rare no matter the diet.[86]
Fancy coffee drinks from trendy coffee joints often pack several hundred calories, thanks to whole milk, whipped cream, sugar, and sugary syrups. A cup of regular coffee with skim milk has just a small fraction of those calories. And when brewed with good beans, it tastes just as great. You can also try nonfat powdered milk in coffee. You’ll get the nutritional benefits of skim milk, which is high in calcium and low in calories. And, because the water has been removed, powdered milk doesn’t dilute the coffee the way skim milk does. Here are 11 metabolism myths you have to stop believing.
Furthermore, fasting for fast weight loss carries additional health risks. Whilst fasting for a day or two is rarely a problem if you are healthy, “it can be quite dangerous if you are not already eating a healthy diet, or if you’ve got liver or kidney problems, any kind of compromised immune system functioning, or are on medication – even Tylenol,” says Dr. Fuhrman.
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]
Some vegetarians also avoid products that may use animal ingredients not included in their labels or which use animal products in their manufacturing. For example, sugars that are whitened with bone char, cheeses that use animal rennet (enzymes from animal stomach lining), gelatin (derived from the collagen inside animals' skin, bones, and connective tissue), some cane sugar (but not beet sugar) and beverages (such as apple juice and alcohol) clarified with gelatin or crushed shellfish and sturgeon, while other vegetarians are unaware of, or do not mind, such ingredients.[3][4][5][6]
Theravadins in general eat meat.[140] If Buddhist monks "see, hear or know" a living animal was killed specifically for them to eat, they must refuse it or else incur an offense.[141] However, this does not include eating meat which was given as alms or commercially purchased. In the Theravada canon, Buddha did not make any comment discouraging them from eating meat (except specific types, such as human, elephant meat, horse, dog, snake, lion, tiger, leopard, bear, and hyena flesh[142]) but he specifically refused to institute vegetarianism in his monastic code when a suggestion had been made.[143][144]

Iodine is a component in thyroid hormones, which help regulate metabolism, growth and function of key organs. Vegans may not get enough iodine and may be at risk of deficiency and possibly even a goiter. In addition, foods such as soybeans, cruciferous vegetables and sweet potatoes may promote a goiter. However, just 1/4 teaspoon of iodized salt a day provides a significant amount of iodine.
One study published in the Journal of American College of Cardiology found that “higher intake of a plant-based diet index rich in healthier plant foods is associated with substantially lower coronary heart disease risk.” (4) Another study published in 2015 in the Permanente Journal found evidence that vegetarian diets can be beneficial for significantly lowering body mass index, high obesity rates, high blood pressure, high triglyceride and cholesterol levels, and diabetes risk. (5)

The Adventist health study is again incorporated into a metastudy titled "Does low meat consumption increase life expectancy in humans?" published in American Journal of Clinical Nutrition, which concluded that low meat eating (less than once per week) and other lifestyle choices significantly increase life expectancy, relative to a group with high meat intake. The study concluded that "The findings from one cohort of healthy adults raises the possibility that long-term (≥ 2 decades) adherence to a vegetarian diet can further produce a significant 3.6-y increase in life expectancy." However, the study also concluded that "Some of the variation in the survival advantage in vegetarians may have been due to marked differences between studies in adjustment for confounders, the definition of vegetarian, measurement error, age distribution, the healthy volunteer effect, and intake of specific plant foods by the vegetarians." It further states that "This raises the possibility that a low-meat, high plant-food dietary pattern may be the true causal protective factor rather than simply elimination of meat from the diet." In a recent review of studies relating low-meat diet patterns to all-cause mortality, Singh noted that "5 out of 5 studies indicated that adults who followed a low meat, high plant-food diet pattern experienced significant or marginally significant decreases in mortality risk relative to other patterns of intake."[117]

We’ve now arrived at tip number 16. If you’re still having trouble losing weight, despite following the 15 pieces of advice listed above, it might be a good idea to bring out the heavy artillery: optimal ketosis. Many people stalling at weight plateaus while on a low-carb diet have found optimal ketosis helpful. It’s what can melt the fat off once again. 

Sattvic diet (also known as yogic diet), a plant-based diet which may also include dairy and honey, but excludes eggs, red lentils, durian, mushrooms, alliums, blue cheeses, fermented foods or sauces, and alcoholic drinks. Coffee, black or green tea, chocolate, nutmeg, and any other type of stimulant (including excessively pungent spices) are sometimes excluded, as well.

Vegetarian can equally be seen as derived from the late Latin 'vegetabile' – meaning plant – as in Regnum Vegetabile / Plant Kingdom. Hence vegetable, vegetation – and vegetarian. Though others suggest that 'vegetable' itself is derived from 'vegetus'. But it's very unlikely that the originators went through all that either – they really did just join 'vegetable+arian', as the dictionaries have said all along.

Archived from the original on March 19, 2018. Retrieved March 18, 2018. For discerning consumers, a recent Health Ministry notification had made it mandatory for packed food containing animal parts contained in a box, to sport a brown dot prominently on its label.
Side effects of fasting may include headaches, weakness, muscle aches, nausea, lightheadedness, irritability, racing heart, exacerbation of joint symptoms, mild abdominal discomfort, and hunger. However, everyone reacts differently to detoxing. While one person may feel energized and revitalized, another may feel sluggish. Generally it is reported that hunger disappear after the first day.
"Amritdharis" that belong to some Sikh sects (e.g. Akhand Kirtani Jatha, Damdami Taksal, Namdhari[202] and Rarionwalay,[203] etc.) are vehemently against the consumption of meat and eggs (though they do consume and encourage the consumption of milk, butter and cheese).[204] This vegetarian stance has been traced back to the times of the British Raj, with the advent of many new Vaishnava converts.[200] In response to the varying views on diet throughout the Sikh population, Sikh Gurus have sought to clarify the Sikh view on diet, stressing their preference only for simplicity of diet. Guru Nanak said that over-consumption of food (Lobh, Greed) involves a drain on the Earth's resources and thus on life.[205][206] Passages from the Guru Granth Sahib (the holy book of Sikhs, also known as the Adi Granth) say that it is "foolish" to argue for the superiority of animal life, because though all life is related, only human life carries more importance: "Only fools argue whether to eat meat or not. Who can define what is meat and what is not meat? Who knows where the sin lies, being a vegetarian or a non-vegetarian?"[200] The Sikh langar, or free temple meal, is largely lacto-vegetarian, though this is understood to be a result of efforts to present a meal that is respectful of the diets of any person who would wish to dine, rather than out of dogma.[199][200]

Vitamin D needs can be met via the human body's own generation upon sufficient and sensible exposure to ultraviolet (UV) light in sunlight.[102][103] Products including milk, soy milk and cereal grains may be fortified to provide a source of Vitamin D.[104] For those who do not get adequate sun exposure or food sources, Vitamin D supplementation may be necessary.
A 1999 metastudy combined data from five studies from western countries.[113] The metastudy reported mortality ratios, where lower numbers indicated fewer deaths, for fish eaters to be 0.82, vegetarians to be 0.84, occasional meat eaters (eat meat less than once per week) to be 0.84. Regular meat eaters had the base mortality rate of 1.0, while the number for vegans was very uncertain (anywhere between 0.7 and 1.44) due to too few data points. The study reported the numbers of deaths in each category, and expected error ranges for each ratio, and adjustments made to the data. However, the "lower mortality was due largely to the relatively low prevalence of smoking in these [vegetarian] cohorts". Out of the major causes of death studied, only one difference in mortality rate was attributed to the difference in diet, as the conclusion states: "...vegetarians had a 24% lower mortality from ischaemic heart disease than non-vegetarians, but no associations of a vegetarian diet with other major causes of death were established".[113]
Some people feel better supplementing the already active T3 (sometimes prepared from pig thyroid glands), as it can give a stronger effect than the T4 hormone, but its effect is often harder to control. Swedish healthcare rarely prescribes or offers such T3 treatment, as it often lacks advantages and may pose a risk when doses are high for an extended period of time.
The first discovered written use of the term "vegetarian" originated in 1839 and refers to what was previously described as a vegetable regimen or diet, for example in print in 1811.[12] Modern dictionaries based on scientific linguistic principles have always explained its origin as an irregular compound of vegetable (in the adjectival sense of any plant still common today)[13] and the suffix -arian (in the sense of "supporter, believer" as in humanitarian), but there were amateur attempts, even by a Latin scholar not trained in linguistics, to find other origins of the word.[14] The term was popularized with the foundation of the Vegetarian Society in Manchester in 1847,[15] although it may have appeared in print before 1847.[15][16][17] The earliest occurrences of the term seem to be related to Alcott House—a school on the north side of Ham Common, London—which was opened in July 1838 by James Pierrepont Greaves.[16][17][18] From 1841, it was known as A Concordium, or Industry Harmony College, from which time the institution began to publish its own pamphlet entitled The Healthian, which provides some of the earliest appearances of the term "vegetarian".[16]

Claims have been made that a normal serving (approx. 3 oz or 1/2 cup, or 60 grams) of mushrooms treated with ultraviolet light increase their vitamin D content to levels up to 80 micrograms,[111] or 2700 IU if exposed to just 5 minutes of UV light after being harvested.[112]
Dairy products contain varying amounts of lactose (milk sugar), which slows down weight loss. What’s more, part of the protein in milk generates a significant insulin response, which can have the same effect. Consequently, cutting back on dairy products may accelerate weight loss. This applies especially to dairy products typically lacking in fat, such as regular milk and various yogurts, but be careful with full-fat dairy such as cream and cheese all the same. And don’t forget whey protein powder, which is pure milk protein.
Buddhist vegetarianism. Different Buddhist traditions have differing teachings on diet, which may also vary for ordained monks and nuns compared to others. Many interpret the precept "not to kill" to require abstinence from meat, but not all. In Taiwan, su vegetarianism excludes not only all animal products but also vegetables in the allium family (which have the characteristic aroma of onion and garlic): onion, garlic, scallions, leeks, chives, or shallots.
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.

To make sure you’re eating enough protein and calories in general, don’t skimp on plants that offer amino acids and healthy fats. How much protein should you aim to eat each day? While it might be possible to get away with less, I personally think it’s best to divide your body weight in half and eat about that many grams of protein per day. Some of the best plant proteins include natto, spirulina, tempeh, nutritional yeast, green peas, lentils, quinoa and amaranth.

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.

Omega-3 fatty acids are good fats that may help lower blood pressure, improve heart health, and stave off age-related dementia. There are two kinds. Most of the health benefits are linked to docosahexaenioc acid (DHA), found mainly in fatty fish, as well as fortified foods like eggs. If you don't eat either of these foods, you might want to consider a supplement. Pumpkin seeds, flaxseeds, walnuts, and canola oil are all good sources of alpha-linolenic acid (ALA), an omega-3 fatty acid beneficial for heart health.
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.
