This comic makes fun of that kind of notion, with [[Cueball]] describing to [[White Hat]] how his '''metabolism''' is special, hence the title. But what he is describing is just 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.

Metabolism
I have this weird thing where if I don't drink enough water, I start feeling bad and then die of dehydration.
Title text: I have this weird thing where if I don't drink enough water, I start feeling bad and then die of dehydration.

Explanation

Ambox notice.png This explanation may be incomplete or incorrect: There have been several comics like this, especially about the (8 glasses of) water. These should be mentioned. And surely there are more to be said.
If you can address this issue, please edit the page! Thanks.

Many people (including dieticians and nutritionists) believe that some individuals (such as themselves) have a special kind of metabolism, usually if they are able to eat a lot and/or whatever they wish and not gain weight from it.

This comic makes fun of that kind of notion, with Cueball describing to White Hat how his metabolism is special, hence the title. But what he is describing is just 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 problem for many people is that they eat so much more than they need to cover their energy needs that they get really fat. This is because human bodies has been created during a time when it was hard to ever find enough to eat, so as soon as there where more than needed for a short period of time it was all a matter of storing as much as possible up as fat, for the hard times that was sure to come. But today these hard times fail to appear, and also the food can be obtained without actually doing any exercise which would be needed if the food had to be gathered either from farming or hunter/gathering. And this is why there is an obesity problem in most first world countries today, especially in the US. Randall has previously shown how bad his health becomes when he starts eating lots of fat (or sweet) food in 418: Stove Ownership.

The title text stretches this further, telling about the normal habit of drinking water (and the consequences of not drinking it) as something odd, i.e starting to feel bad at first and eventually dying if refraining from drinking for too long a time.. 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.

This is the second comic in a row about food, the previous being 1743: Coffee.

Transcript

[Cueball, on the left, and White Hat are sitting on chairs on either side of a table, facing each other. They each have plates of food and glasses of some beverage set in front of them. Each has picked up a portion of food on a fork to eat it.]
Cueball: I have one of those metabolisms where I can eat whatever I want and my body converts it to energy and stores the excess as fat.

Discussion

I think the comics explanation should include dieticians.162.158.49.12 14:58, 10 October 2016 (UTC)

A reference on the topic of metabolic energy balance and common beliefs surrounding it: http://ajcn.nutrition.org/content/95/4/989.full 162.158.34.149 17:47, 10 October 2016 (UTC)

If it was White Hat saying this, I'd expect him to be literally able to eat whatever he wants, even items that are not normally edible. It is not, however (which is strange, because, even aside from that alternate interpretation, it sounds a lot like his style). --172.68.11.36 02:56, 11 October 2016 (UTC)

I'd say in that case it had to be Beret Guy instead of White Hat. Elektrizikekswerk (talk) 07:31, 11 October 2016 (UTC)
I agree - not sure why I mistook one for the other. --172.68.11.39 12:11, 11 October 2016 (UTC)

I have one of those metabolisms where if I eat more than what I need, I sweat a lot during the night and I never fatten. I'm always underweight. é_è Seipas (talk) 09:07, 11 October 2016 (UTC)

The explaination is mistaken. It is indeed possible to eat and not gain weight, and well document and most parts of it understood by medicine. Excess energy is only stored as fat if the body is stressed, you can piss out the sugar or the intestines can absorb less. The problem with the idea is that is hard to impossible to correct what your body does in this regard which makes is a red herring for the already overweight. 162.158.87.11 16:45, 11 October 2016 (UTC)

It's even worse: if you try some diet to reduce weight and you start feeling hungry due to this diet, your body will interpret it as signal that it needs to work harder to preserve and/or obtain energy. When you stop the diet, you will then gain even more weight, which is also known as Yo-yo effect. Overweight people who already tried multiple diets, some of them based on bad ideas, will typically get more fat from the same food than people who never cared. -- Hkmaly (talk) 13:37, 13 October 2016 (UTC)

Technically, Cueball says he can eat "'whatever I want," which would imply he could eat traditionally non-edible items. I don't think this is actually intended based on context, but... 108.162.218.154 (talk) (please sign your comments with ~~~~)

Mentioned already in my comment above (and the discussion after it). It would probably have been intended if that was Beret Guy, but that's not Beret Guy. --172.68.11.36 20:48, 14 October 2016 (UTC)

It may be coincidence but this comic was published the day before the Yom Kippur (Day of Atonement) Jewish fast. There was a reference to the Jewish calendar a few comics ago. 141.101.104.123 (talk) (please sign your comments with ~~~~)

This is stated too strongly. Most of our energy consumed goes toward our basal metabolic rate, which does seem to vary among individuals. 108.162.215.134 19:22, 14 October 2016 (UTC)

You can think about this topic as much as you want. The final answer is sports. Always. Beautiful women do sports. REAL men do sports. It's all so simple. 162.158.83.144 (talk) (please sign your comments with ~~~~)

There actually is a gene that controls insulin response to blood sugar, and it comes in two allies, one for low, and one for high. These mix, giving low, medium, medium, high.

It turns out that "low" corresponds to people that have trouble putting on fat, "high" corresponds to insulin resistance diabetes, and "medium" corresponds to most people who wind up overweight / needing to exercise.
