Need to understand how resistant starch modified carbs play in this. So, rice chilled and re-heated. Reheated spuds. Not sure how you can do this with bread but maybe secondary cooking (toast) gets you there?

Also, is this another nail in the coffin for "all calories are the same" ? Feels like it.

I am not a mouse, but I definitely preference some carbs over others. Mind you, given a choice between snacking on an umami laden bowl of salami, cheese, miso, burnt-crunchy-bits-from-the-dinner-roast or carbs, I'd eat all of them.

Some youtuber tested cooled rice or something to test regular vs resistant starch using a glucose monitor and found zero difference in his blood sugar response.

So while there might be gut bacteria effect changes of it some people at least show no different blood glucose response.

Since Ozempic came out it should be obvious even to the most hardcore "all calories are the same" people that this is blatently false and that the hormonal response to foods is what drives satiety, not "calories".

The "all calories are the same" statement doesn't mean that all foods with the same caloric values satiate you the same, and no one has ever claimed that. In fact it's very common knowledge; the entire basis of diets like keto that remove carbs, the least satiating of the marcos per calorie.

The only thing hormones can affect is your maintenance requirement, meaning you can gain weight if your body chooses to store the calories instead of burning them for whatever reason, even while eating the same as always.

>In fact it's very common knowledge; the entire basis of diets like keto that remove carbs, the least satiating of the marcos per calorie.

I don't think that's true. I think the basis of keto is ketosis, not a matter of satiety per calories.

Keto people tend to be too reductionist on carbs and macro nutrients and insulin response. Carbs shouldn’t be a euphemism for junk food. And the potato is the most satiating food at 90% carbs.

From personal experience keto has convinced binge eaters that they need to wear a CGM and avoid foods like beans and carrots, foods they weren’t eating much of in the first place but probably should eat more of.

I may be missing something, but isn't the focus on calories about weight gain, not feeling full?

Yes, “all calories are the same” is a statement about thermodynamics, not the subjective experience of eating.

People who value other things higher than how it feels to eat and be full, like athletes and actors, can accurately manage their weight with calorie counting. It’s often not a pleasurable experience, but they subject themselves to it to meet their professional goals.

Feeling full matter a lot. It drives when you stop eating, fetch something else to eat and also is related to how active you are. It drives whether your thoughts are turning back to figuring out where to get food or whether they happily go elsewhere with no effort.

> why bread can cause weight gain

> When wheat flour was removed from the diet, both body weight and metabolic abnormalities improved quickly.

Bread is not only wheat flour. And humans do not eat flour.

Maybe the added sugar in "bread" has a role ?

This what I call peasant metabolism.
