I've lost a small amount of weight whilst still entirely eating bread this year. The only thing food groups have to do with it is how filling everything is

It's incredible how much bizarre pseudoscience exists to dance around this simple fact.

Even with ketosis (a real thing), 99% of its dietary weight loss effectiveness is because fat is filling.

This is pretty easy to disprove. It's not at all that fat is more filling.

Once your body starts to burn it's own fat you no longer feel like you're starving. Anyone whose fasted could tell you that, never mind been on keto.

The starving feeling comes from the period in between where your body is waiting for more carbs before finally switching to fat burning mode.

So it's not that fat is filling. Carbs are filling, too. It's just that when carbs are burned, there's nothing to replace them with, but when the fat you've consumed has gone through your system, and your body is already in Ketosis, it doesn't feel bad because there's weeks and months worth of food already on your body to burn.

I like of feel like it's easy to "prove" the opposite.

If I eat a meal comprised of fat and protein (2 fried eggs with some cheese, for example), I'll feel sated and won't feel hungry again for up to 5 hours.

On the other hand, it I eat a bowl of pasta, I'll feel very full immediately after eating, but am guaranteed to feel hungry again in ~2h.

I firmly believe that fat and protein are more "filling" than than carbs, and many people have shared similar anecdotes.

This is the stereotypical speculation that comes with diet claims.

I lost a lot of pounds one summer when I used to live in a school that served vegetarian food only for religious reasons. The reason I lost almost 30 to 40 pounds is I cooked my own food which was vegetarian, but probably didn't use the high sugar the cafeteria used to compensate for the lack of meat. A lot of it is simple energy in and energy out. People honestly really underestimate their energy in and overestimate their energy out.

Everything's relative, what was your diet before you embarked on your -100# pasta dish diet? Pasta dishes chased by ice cream and snickers bars?

Pasta dishes in larger portions with less exercise and a stressful commute.

I know multiple people with type two diabetes who aren't overweight. They have good genes with regards to weight, yet bad genes with regards to blood sugar. One of these people runs every day.

Carbs are not bad for you in moderation, but if your body is drowned in them you can easily develop blood sugar problems, especially if you're predisposed to it. Otherwise, if you're highly active and aren't constantly eating more calories than you burn then of course you will have a healthy weight.

I'm not being anti carb or anything. It's just waaaaaay easier to cut them out, lose a bunch of weight, then reintroduce them in moderation, than to try and burn off an excess of calories each day via intense exercise.
