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]
Surprisingly, some people who consider themselves vegetarian continue to consume products that contain remains of slaughtered animals such as gelatin (made from ground-up skin and bones, found in Jell-O, supplement capsules, and photographic film) and rennet (made from the lining of calves' stomachs, used to coagulate hard cheese). Some of these people may be unaware that these hidden animal ingredients even exist. Others know about them but feel that they are just minor components of a product, and that their presence is therefore not important. [...] Many people who do not eat meat for ethical reasons do use animal by-products that are obtained while the animals are still alive. Dairy is a good example, as many vegetarians who consume it rationalize their behavior by pointing out that cows are not killed in order to provide humans with this particular by-product.
The main advantage of the low-carb diet is that it causes you to want to eat less. Even without counting calories most overweight people eat far fewer calories on low carb. Sugar and starch may increase your hunger, while avoiding them may decrease your appetite to an adequate level. If your body wants to have an appropriate number of calories you don’t need to bother counting them. Thus: Calories count, but you don’t need to count them. 

The relationship between vegetarian diet and bone health remains unclear. According to some studies, a vegetarian lifestyle can be associated with vitamin B 12 deficiency and low bone mineral density.[58] However, a study of vegetarian and non-vegetarian adults in Taiwan found no significant difference in bone mineral density between the two groups.[59] Other studies, exploring animal protein's negative effects on bone health, suggest that vegetarians may be less prone to osteoporosis than omnivores, as vegetarian subjects had greater bone mineral density[60] and more bone formation.[61]
You can eat twice as much pasta salad loaded with veggies like broccoli, carrots, and tomatoes for the same calories as a pasta salad sporting just mayonnaise. Same goes for stir-fries, omelets, and other veggie-friendly dishes. If you eat a 1:1 ratio of grains to veggies, the high-fiber veggies will help satisfy your hunger before you overeat the grains. Bonus: Fiber is highly beneficial for preventing constipation, which can make you look bloated.
1842: "To tell a healthy vegetarian that his diet is very uncongenial with the wants of his nature." (Healthian, Apr. 34) The 1839 occurrence remains under discussion; the Oxford English Dictionary's 1839 source is in fact an 1863 publication: Fanny Kemble, Journal of a Residence on a Georgian Plantation 1838–1839. The original manuscript has not been located.
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.
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.

Many adherents of vegetarianism and veganism – former Beatle Paul McCartney and actor Alec Baldwin are two celebrities who happily promote the cause -- regard a flesh-free diet not only as more healthful, but as a more ethical way to live. They point to the cruel practices and the high environmental cost of raising animals for food as reasons for excluding meat from the diet.


Calcium helps build and maintain strong teeth and bones. Milk and dairy foods are highest in calcium. However, dark green vegetables, such as turnip and collard greens, kale, and broccoli, are good plant sources when eaten in sufficient quantities. Calcium-enriched and fortified products, including juices, cereals, soy milk, soy yogurt and tofu, are other options.
Low levels of vitamin B12 — You can only get vitamin B12 in substantial amounts by consuming meat, fish, eggs and dairy. Cutting out all of these foods can sometimes be problematic and contribute to vitamin B12 deficiency symptoms like fatigue, weakness and others. For this reason it’s recommended that all vegetarians and vegans who abstain from eating most or all animal foods take vitamin B12 supplements.
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]

So how does this work? A quick run-through: The first tip was to eat low carb. This is because a low-carb diet lowers your levels of the fat-storing hormone insulin, allowing your fat deposits to shrink and release their stored energy. This tends to cause you to want to consume fewer calories than you expend – without hunger – and lose weight. Several of the tips mentioned above are about fine-tuning your diet to better this effect.
Vitamin B-12 is necessary to produce red blood cells and prevent anemia. This vitamin is found almost exclusively in animal products, so it can be difficult to get enough B-12 on a vegan diet. Vitamin B-12 deficiency may go undetected in people who eat a vegan diet. This is because the vegan diet is rich in a vitamin called folate, which may mask deficiency in vitamin B-12 until severe problems occur. For this reason, it's important for vegans to consider vitamin supplements, vitamin-enriched cereals and fortified soy products.
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.

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]

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.


 '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.

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]


The Academy of Nutrition and Dietetics and Dietitians of Canada have stated that at all stages of life, a properly planned vegetarian diet is "healthful, nutritionally adequate, and provides health benefits in the prevention and treatment of certain diseases".[52] Large-scale studies have shown that mortality from ischemic heart disease was 30% lower among vegetarian men and 20% lower among vegetarian women than in non-vegetarians.[53][54] Vegetarian diets offer lower levels of saturated fat, cholesterol and animal protein, and higher levels of carbohydrates, fibre, magnesium, potassium, folate, and antioxidants such as vitamins C and E and phytochemicals.[55][56]
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]

Not much of a coffee drinker? Tea is also a natural diuretic, and types of herbal tea such as dandelion or fennel root can also lend a hand. In fact: When a recent study compared the metabolic effect of green tea (in extract) with that of a placebo, researchers found that the green-tea drinkers burned about 70 additional calories in a 24-hour period.
^ Gyani Sher Singh, Philosophy of Sikhism, Shiromani Gurdwara Parbandhak Committee, Amritsar: "As a true Vaisnavite, Kabir remained a strict vegetarian. Kabir, far from defying Brahmanical tradition as to the eating of meat, would not permit so much as the plucking of a flower (G.G.S. p. 479), whereas Nanak deemed all such scruples to be superstitions."

A body of research out of Pennsylvania State University finds that eating water-rich foods such as zucchini, tomatoes, and cucumbers during meals reduces your overall calorie consumption. Other water-rich foods include soups and salads. You won’t get the same benefits by just drinking your water, though (but you will get other benefits of staying hydrated). Because the body processes hunger and thirst through different mechanisms, it simply doesn’t register a sense of fullness with water (or soda, tea, coffee, or juice). Here are 15 weight loss tips doctors wish you would stop following. 

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.
Low levels of vitamin B12 — You can only get vitamin B12 in substantial amounts by consuming meat, fish, eggs and dairy. Cutting out all of these foods can sometimes be problematic and contribute to vitamin B12 deficiency symptoms like fatigue, weakness and others. For this reason it’s recommended that all vegetarians and vegans who abstain from eating most or all animal foods take vitamin B12 supplements.

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]
Don't get me wrong — exercising at any time is good for you. But evening activity may be particularly beneficial because many people's metabolism slows down toward the end of the day. Thirty minutes of aerobic activity before dinner increases your metabolic rate and may keep it elevated for another two or three hours, even after you've stopped moving. What that means for you: You're less likely to go back for seconds or thirds. Plus, it'll help you relax post meal so you won't be tempted by stress-induced grazing that can rack up calories, quickly.

This drug is an injected variant of a satiety hormone called GLP-1. It slows down how quickly the stomach empties and tells the brain that you don’t need to eat yet – a great idea for losing weight. As a bonus this drug works fine while one is on the keto diet and it works even better with intermittent fasting – for a rapid weight loss with no hunger.

Packaged and processed foods, such as cakes, cookies, candies, chocolate, yogurt, and marshmallows, often contain unfamiliar animal ingredients, so may be a special concern for vegetarians due to the likelihood of such additions.[3][5] Often, prior to purchase or consumption, vegetarians will scrutinize products for animal-derived ingredients.[5] Vegetarians' feelings vary with regard to these ingredients. For example, while some vegetarians may be unaware of animal-derived rennet's role in the production of cheese, and may therefore unknowingly consume the product,[3][6][7] other vegetarians may not take issue with its consumption.[3][4]
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.
"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
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.
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.
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.

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.
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.
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.
Protein helps maintain healthy skin, bones, muscles and organs. Eggs and dairy products are good sources, and you don't need to eat large amounts to meet your protein needs. You can also get sufficient protein from plant-based foods if you eat a variety of them throughout the day. Plant sources include soy products and meat substitutes, legumes, lentils, nuts, seeds, and whole grains. 

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.
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.
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.
