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”.
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]
According to the United States National Institutes of Health, vitamin B12 is not generally present in plants and is naturally found in foods of animal origin.[87] Lacto-ovo vegetarians can obtain B12 from dairy products and eggs, and vegans can obtain it from fortified foods (including some soy products and some breakfast cereals) and dietary supplements.[88][89][90][91][92] Vitamin B12 can also be obtained from fortified yeast extract products.[93]
You might feel silly, but it works. When Alan R. Hirsch, MD, neurological director of the Smell & Taste Treatment and Research Foundation in Chicago, tried this with 3,000 volunteers, he found that the more frequently people sniffed, the less hungry they were and the more weight they lost—an average of 30 pounds each. One theory is that sniffing the food tricks the brain into thinking you’re actually eating it.
At least one study indicates that vegetarian women are more likely to have female babies. A study of 6,000 pregnant women in 1998 "found that while the national average in Britain is 106 boys born to every 100 girls, for vegetarian mothers the ratio was just 85 boys to 100 girls".[223] Catherine Collins of the British Dietetic Association has dismissed this as a "statistical fluke" given that it is actually the male's genetic contribution which determines the sex of a baby.[223]

Although zinc is found in many vegetarian foods, it is not as well absorbed as meat-based zinc. Eating plenty of zinc-rich foods can help you maximize the amount your body absorbs. Good sources include milk, cheese, whole-grain breads, nuts, soy foods, and legumes, such as chickpeas. Hummus on a whole-grain pita is one tasty snack that does the trick.

Your body needs a certain amount of essential vitamins and minerals to function properly. What happens when you don’t get enough of them? What happens when you eat too little food, or when the food you eat isn’t sufficiently nutritious? Perhaps our bodies catch on and reply by increasing hunger levels. After all – if we eat more, we increase the chances of consuming enough of whatever nutrient we are lacking.
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]
Side effects of fasting include dizziness, headaches, low blood sugar, muscle aches, weakness, and fatigue. Prolonged fasting can lead to anemia, a weakened immune system, liver and kidney problems, and irregular heartbeat. Fasting can also result in vitamin and mineral deficiencies, muscle breakdown, and diarrhea. When you drink laxative concoctions during a fast, there is an increased risk of fluid imbalance and dehydration.

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.
