I think the comics explanation should include dieticians. 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 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). -- 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. -- 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. 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... (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. -- 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. (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. 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. (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.
