question: why I'm full after eating and get so tired? Bacon cheeseburger with lettuce, tomato, pickles, and a side of fries for a late lunch, not fast food, with a water and I don't want to move!
comment: because all the oxygen in your blood is getting redirected from your brain to your digestive system to process the food
passages: Fast food servings, for example, are 2 to 5 times larger than they were in the 1980s. Evidence has shown that larger portions of energy-dense foods lead to greater energy intake and thus to greater rates of obesity.

   BULLET::::- Satiation occurs when the brain acknowledges that enough food has been eaten; there are triggers in the body that send these signals to the brain. Sizer and Whitney say a, “Greater exposure of the mouth to food triggers increased satiation. When the stomach stretches to accommodate a meal, nerve receptors in the stomach fire, sending a signal to the brain that the stomach is full”. Healthy snacks are ones that leave the body feeling filled so that it does not continue to signal to the brain that it still wants food.
   Day 2 brings Spurlock's first (of nine) Super Size meal, at the McDonald's on 34th Street and Tenth Avenue, which is a meal made of a Double Quarter Pounder with Cheese, Super Size French fries, and a 42-ounce Coca-Cola, which takes 22 minutes to eat. He experiences steadily increasing stomach discomfort during the process, and then vomits in the McDonald's parking lot.
   Portion sizes in the United States have increased markedly in the past several decades. For example, from 1977 to 1996, portion sizes increased by 60 percent for salty snacks and 52 percent for soft drinks. Importantly, larger product portion sizes and larger servings in restaurants and kitchens consistently increase food intake. Larger portion sizes may even cause people to eat more of foods that are ostensibly distasteful; in one study individuals ate significantly more stale, two-week-old popcorn when it was served in a large versus a medium-sized container.

   A short epilogue was added to the film. It showed that the salads can contain even more calories than burgers if the customer adds liberal amounts of cheese and dressing prior to consumption. Also, it described McDonald's discontinuation of the Super Size option six weeks after the movie's premiere, as well as its recent emphasis on healthier menu items such as salads, and the release of the new adult Happy Meal. McDonald's denied that these changes had anything to do with the film.
  
  Section::::Reception.
   BULLET::::- Satiety occurs after a snack, suppressing hunger or regulating how often the body desires food. Choosing snacks that have high water content, are airy, and are high in fiber and protein causes stronger satiety signals and thus lengthens the time between meals. Fat triggers a hormone that increases satiety as well.
  
  Section::::Healthy snacking.:Nutrient density and energy density.
   Simple carbohydrates are absorbed quickly, and therefore raise blood-sugar levels more rapidly than other nutrients. However, the most important plant carbohydrate nutrient, starch, varies in its absorption. Gelatinized starch (starch heated for a few minutes in the presence of water) is far more digestible than plain starch, and starch which has been divided into fine particles is also more absorbable during digestion. The increased effort and decreased availability reduces the available energy from starchy foods substantially and can be seen experimentally in rats and anecdotally in humans. Additionally, up to a third of dietary starch may be unavailable due to mechanical or chemical difficulty.
   The title is based on the American film "Super Size Me" where the author consumes McDonald's daily for a month.

  Section::::Content.:Experiment.
   In 2007, Tim was a test subject in a documentary, "The Science of Speed Eating" from National Geographic. He underwent an upper gastrointestinal series and was shown to have a stomach that expands four times larger than a normal stomach. His digestive rate of the stomach was also slower than a normal human.
   As told in the textbook "Nutrition: Concepts and Controversies" by Frances Sienkiewicz Sizer and Ellie Whitney, sedentary men have a recommended daily calorie intake of about 2400 kcal. For sedentary women the intake is about 2000 kcal. The average calorie intake during a meal is about 500 kilocalories leaving a range of 300-800 kilocalories for snacks between meals. Overdoing this daily allowance can cause weight gain no matter whether the snack is healthy or unhealthy.
  
  Section::::Healthy snacking.
   Carbohydrate loading is generally recommended for endurance events lasting longer than 120 minutes. Many endurance athletes prefer foods with low glycemic indices for carbo-loading due to their minimal effect on serum glucose levels. Low glycemic foods commonly include vegetables, whole wheat pasta, and grains. Many marathoners and triathlon participants have large pasta dinners the night before the race. Since muscles also use amino acids extensively when functioning within aerobic limits, meals should also include adequate protein. Large portions before a race can, however, decrease race-day performance if the digestive system has not had the time to process the food regimen.
   Agricultural policy and techniques in the United States and Europe have led to lower food prices. In the United States, subsidization of corn, soy, wheat, and rice through the U.S. farm bill has made the main sources of processed food cheap compared to fruits and vegetables. Calorie count laws and nutrition facts labels attempt to steer people toward making healthier food choices, including awareness of how much food energy is being consumed.
   Section::::In popular culture.
  
  Meal replacements have been a regular feature of science fiction, especially the space travel genre, at least since the film "Santa Claus Conquers the Martians" (1964) and TV's "Lost in Space" (1965).

   Section::::Strategies for maintaining a healthy weight.:Incorporating more vegetables into meals.
  
  Fruits and vegetables have been shown to increase satiety and decrease hunger. These foods have a low energy density, which is mainly due to the high water content and partly due to the fiber content. The reduction of energy density has been shown to enhance satiety. The water adds weight, without adding calories and the fiber slows gastric emptying. Both of these factors contribute to the satiating effect of vegetables and fruits. Studies have also shown that fiber decreases hunger and also decreases total energy intake.
   It is critical to look at car ownership in relation to the distance and number of stores in the area. Distance from shops influences the quality of food eaten. A car or public transportation is often needed to access a grocery store. When neither a car or nor public transportation is available, diets are rarely healthy. This is because fast food and convenience stores are easier to access and do not cost much money or time. Further, those who walk to food shops typically have poorer diets, which has been attributed to having to carry shopping bags home.
   BULLET::::- Emotional eating occurs when people use food to cope with emotional triggers including boredom, procrastination, excitement, love, frustration, stress, and mild depression.
  
  BULLET::::- Eating for convenience and food availability occurs when people choose to snack on energy-dense food that is readily available. In some areas the only food available is processed food, which is energy-dense and low in essential nutrients. Sizer and Whitney say, “A steady diet of such foods can easily lead to both obesity and malnutrition”. These foods are high in calories, fat, salt, and have a very low nutrient density.
  
  Section::::Consumer perception.
   After John Cisna, a high school science teacher, lost 60 pounds while eating exclusively at McDonald's for 180 days, he said, "I'm not pushing McDonald's. I'm not pushing fast food. I'm pushing taking accountability and making the right choice for you individually... As a science teacher, I would never show "Super Size Me" because when I watched that, I never saw the educational value in that... I mean, a guy eats uncontrollable amounts of food, stops exercising, and the whole world is surprised he puts on weight? What I'm not proud about is probably 70 to 80 percent of my colleagues across the United States still show "Super Size Me" in their health class or their biology class. I don't get it."
   Section::::Low carbohydrate versus low fat.
  
  Low-carbohydrate and low-fat diets perform similarly in the long term as weight maintenance depends on calorie intake, not macronutrient ration.
  
  Section::::Low glycemic index.
  
  "The glycemic index (GI) factor is a ranking of foods based on their overall effect on blood sugar levels. The diet based around this research is called the Low GI diet. Low glycemic index foods, such as lentils, provide a slower, more consistent source of glucose to the bloodstream, thereby stimulating less insulin release than high glycemic index foods, such as white bread."
   Excessive snacking is another behavior that can be explained by mental accounting. For an expense (or calorie influx) to be considered in future decisions, it must be budgeted: tracked and placed in an appropriate account. Small expenses, however, are often left unbudgeted (due to their insignificant size or influence on the aggregate), and thus do not affect future decisions. This idea is very robust when we are snacking. Each additional handful of pretzels (or chips) holds a relatively insignificant number of calories, when compared to the total have been consumed in the snacking session. Thus, it is very easy to convince oneself to take another handful (“I’ll just have one more”). Each handful is liable to be budgeted poorly, or left completely unbooked and forgotten, and this can cause us to snack more than we planned or wanted.
   Normally, eating is pleasant when an individual is hungry and less pleasant when an individual is full. Neuronal activation in the OFC decreases when an individual is full, however there is a disturbance in this pathway in individuals with AN and BN. Thus, patients with AN have little response to food or a quick response to being full, and patients with BN have an exaggerated response to food or a decrease in feeling full.
   Roberts argued that weight is controlled by maintaining body fat at a certain amount, referred to as a "set point." When weight is above the set point, appetite decreases, and it takes less food to feel full. When weight is below the set point, appetite increases, and it takes more food to feel full. He further stated that eating strongly flavored foods (like soda or donuts) can raise the set point, whereas flavorless foods (like sugar water, canola oil, extra light olive oil) can lower the set point. These flavorless foods must be consumed in a "flavorless window," at least one hour after and one hour before consuming flavors. Consumption of 100-400 flavorless calories per day lowers the set point, and therefore, lowers weight.
   A review of eating habits in the United States in 2004 found that about 75% of restaurant meals were from fast-food restaurants. Nearly half of the meals ordered from a menu were hamburger, French fries, or poultry — and about one third of orders included a carbonated beverage drink. From 1970 to 2008, the per capita consumption of calories increased by nearly one-quarter in the United States and about 10% of all calories were from high-fructose corn syrup.
   Jared Fogle’s drastic weight loss on a Subway diet is another case that poses a fair debate against the idea that the culprit of obesity is fast food. Fogle dropped 235 pounds by consuming Subway sandwiches for lunch and dinner daily. With no cheese or mayonnaise, the calories of both sandwiches totaled less than 1,000 calories in a day.
   Section::::Fast food.
  
  As societies become increasingly reliant on energy-dense fast-food meals, the association between fast food consumption and obesity becomes more concerning. In the United States consumption of fast food meal has tripled and calorie intake from fast food has quadrupled between 1977 and 1995. Consumption of sweetened drinks is also believed to be a major contributor to the rising rates of obesity.
  
  Section::::Portion size.
  
  The portion size of many prepackage and restaurant foods has increased in both the United States and Denmark since the 1970s.
   Section::::Strategies for maintaining a healthy weight.:Eating more soup.
  
  Soups have a significant effect on satiety. Studies have demonstrated that when compared to solid foods, soup ingestion decreases the amount of energy intake. When soup is consumed before a meal, there is a 20% decrease in the number of calories consumed during the meal.
