Though there is no strict rule on what to consume and what not to, paths of Hinduism hold vegetarianism as an ideal. Some reasons are: the principle of nonviolence (ahimsa) applied to animals;[173] the intention to offer only "pure" (vegetarian) food to a deity and then to receive it back as prasad; and the conviction that a sattvic diet is beneficial for a healthy body and mind and that non-vegetarian food is not recommended for a better mind and for spiritual development. 

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]
Iron is a crucial component of red blood cells. Dried beans and peas, lentils, enriched cereals, whole-grain products, dark leafy green vegetables, and dried fruit are good sources of iron. Because iron isn't as easily absorbed from plant sources, the recommended intake of iron for vegetarians is almost double that recommended for nonvegetarians. To help your body absorb iron, eat foods rich in vitamin C, such as strawberries, citrus fruits, tomatoes, cabbage and broccoli, at the same time as you're eating iron-containing foods.
Within the Afro-Caribbean community, a minority are Rastafari and follow the dietary regulations with varying degrees of strictness. The most orthodox eat only "Ital" or natural foods, in which the matching of herbs or spices with vegetables is the result of long tradition originating from the African ancestry and cultural heritage of Rastafari.[193] "Ital", which is derived from the word vital, means essential to human existence. Ital cooking in its strictest form prohibits the use of salt, meat (especially pork), preservatives, colorings, flavorings and anything artificial.[194] Most Rastafari are vegetarian.[195]
Everything changes; nothing dies; the soul roams to and fro, now here, now there, and takes what frame it will, passing from beast to man, from our own form to beast and never dies...Therefore lest appetite and greed destroy the bonds of love and duty, heed my message! Abstain! Never by slaughter dispossess souls that are kin and nourish blood with blood![129]
Loads of research demonstrates people who log everything they eat — especially those who log while they're eating — are more likely to lose weight and keep it off for the long-haul. Start tracking on an app like MyFitnessPal when the pounds start sneaking up on you. It'll help you stay accountable for what you've eaten. Plus, you can easily identify some other areas of your daily eats that could use a little improvement when it's written out in front of you.
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]
As funny as it sounds, sleep deprivation may make you fat — and not just because you're susceptible to cases of the late-night munchies (although there's that too). There's tons of research that demonstrates getting less than the desired amount — about 7 hours — of sleep per night can slow down your metabolism. Plus, when you're awake for longer, you're naturally more likely to nosh. So don't skimp on your ZZZs, and you'll be rewarded with an extra edge when it comes to shedding pounds quickly.
Fasting is often used to break the physical aspect of food addiction or a bad cycle of eating. However, it will not necessarily break the emotional ties to addiction. Fasting may stop your body from physiological addiction, but often only disciplined eating can effectively break the deeper emotional addictions by replacing life-long, entrenched, comfort-eating patterns with new healthy ones. You must replace you old damaging habit with a new healthy habit. Commencing a raw food diet and following it for about half the fasting period after fasting will greatly help with any cravings, by allowing an emotional transition from fasting to eating, while still maintaining the need for discipline.
The tenets of Sikhism do not advocate a particular stance on either vegetarianism or the consumption of meat,[196][197][198][199] but leave the decision of diet to the individual.[200] The tenth guru, Guru Gobind Singh, however, prohibited "Amritdhari" Sikhs, or those that follow the Sikh Rehat Maryada (the Official Sikh Code of Conduct)[201] from eating Kutha meat, or meat which has been obtained from animals which have been killed in a ritualistic way. This is understood to have been for the political reason of maintaining independence from the then-new Muslim hegemony, as Muslims largely adhere to the ritualistic halal diet.[196][200]

However, after fasting people often report a positive, healthy change in their diet and lifestyle and thus it can be a springboard in the right direction. Remember for permanent weight loss, you need to adopt a permanent lifestyle change: lowered fat intake, increased intake of unrefined foods (it will fill you up, with minimal calories), decreased consumption of refined foods, drink plenty of water whilst cutting down on other liquids, exercise and get more sleep. Simple and logical! It’s not rocket science. Simply, hard graft, determination and self-discipline!
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.

Many studies of the cancer-vegetarian relationship conclude that diets rich in fiber, vitamins, minerals, isoflavones (found in soybeans, chickpeas, peanuts, and more), and carotenoids (found in carrots, sweet potatoes, broccoli, kale, spinach, tomatoes, red peppers, and more), seem to protect against disease, including cancer, when part of a health-conscious lifestyle.

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.
