+ | Eating is fundamentally a process where energy from food gets absorbed into the body in order to drive muscle movement, growth, and other bodily functions. Energy that is absorbed but not needed in the short term gets converted and stored as body fat. Consuming too much food and not exercising enough are major factors for {{w|obesity}}, which is a problem in many first world countries today, {{w|Obesity in the United States|especially in the United States}}. | ||
− | For obese people, losing weight is often an enormously difficult task. Standing in stark contrast, there are also lean people who do not seem to ever gain any weight even though they appear to eat whatever and however much they want. This leads some people (including the lean people themselves) to believe that one can have a special {{w|metabolism}} where excess food energy somehow does not affect the body. This belief is common, though not supported by scientific evidence. The comic makes fun of that kind of notion. While [[Cueball]] describes to [[White Hat]] how his metabolism is "special" | + | For obese people, losing weight is often an enormously difficult task.

This belief is common, though not supported by scientific evidence. The comic makes fun of that kind of notion. While [[Cueball]] describes to [[White Hat]] how his metabolism is "special", he is in fact only describing the normal case: no matter what he eats, his body converts the food to energy and stores any excess food as fat which stays in his body for future use. |
− | The title text stretches this further, telling about the normal habit of drinking water (and the consequences of not drinking it) as something odd. Starting to feel bad at first and eventually dying if refraining from drinking for too long a time are perfectly normal consequences of dehydration. | + | The title text stretches this further, telling about the normal habit of drinking water (and the consequences of not drinking it) as something odd. Starting to feel bad at first and eventually dying if refraining from drinking for too long a time are perfectly normal consequences of dehydration. It is less than three months ago that Randall referred to dehydration and the 8 glasses of water a day rule in [[1708: Dehydration]]. In that comic [[Megan]] found out she began feeling bad if she did not drink for a a full day. That comic also began with Cueball and White Hat talking. |
− | Obesity has only fairly recently become a public health issue due to lifestyle changes brought on by technologies such as industrialization and trade. Human bodies evolved under conditions where it was hard to ever find enough to eat, so to store as much excess energy as possible as fat was a beneficial adaptation. Historically, stored fat would be consumed during hard times that was sure to come. The act of collecting food through farming or hunting/gathering also demanded physical labor which limited the amount of excess energy that would remain. In comparison, people nowadays hardly need to expend any energy to buy their food from a nearby market. They also have much more sedentary lifestyles and rarely ever go hungry. Without an active commitment to exercise more or eat less, there would almost never be a shortage of energy and no chance for body fat to be used. Randall has previously shown how bad his health becomes when he starts eating lots of fat (or sweet) food in [[418: Stove Ownership]]. | + | Obesity has only fairly recently become a public health issue due to lifestyle changes brought on by technologies such as industrialization and trade.

− | There are many rational explanations for why some people might not gain weight despite eating a lot. For example, it's possible that they only eat a lot during special occasions and social gatherings, where they are easily '''seen''' eating. On more private occasions when no one is watching, they could just as well eat much less or even skip entire meals. They might also lead a much more active lifestyle and thus require more energy than an average person despite their thin appearance. Other less pleasant reasons might include chronic diseases | + | There are many rational explanations for why some people might not gain weight despite eating a lot.
