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.
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.
"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
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.

A History of Vegetarianism, London 1993, p. 252. The OED writes that the word came into general use after the formation of the Vegetarian Society at Ramsgate in 1847, though it offers two examples of usage from 1839 and 1842:
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.
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.
