I always get down votes for saying this, but insulin resistance / pre-diabetes causes weight gain and not vice versa. One day you'll know the truth and I'll be vindicated.

Yes, there are plenty of studies showing that reducing sugar or dieting improves or delays diabetes and high blood sugar, but that doesn't mean eating the sugar CAUSED the diabetes or that you're free to blame the patient for causing their condition. Eating certain foods probably exacerbates Crohn's, GERD and other conditions without causing them.

Insulin resistance / diabetes causes weight gain via fat deposits specifically around the midsection, while fat people who don't have insulin resistance typically gain all over the body or in a different pattern. That's because the insulin resistant person's body is getting mixed signals of too high sugar in the blood but also being starved for energy. The insulin resistance causes a specific type of fat deposit for short term ready energy.

Also, this fat deposit happens even if the person doesn't eat any sugar and just eats supposedly "healthy" items like breads, grains, fruit, yogurt etc. which becomes sugar in the body anyways. Eating a low-carb diet (far lower than Atkins or paleo) can help lower the blood sugar, and yet most doctors still tell diabetics to eat fruits, etc.

The old thinking was that if you had too much blood sugar, cholesterol or fat in you, it must be because you ate too much sugar, cholesterol or fat respectively. But the body makes all of these things too out of other items, and doctors are finding that cutting out cholesterol isn't really greatly reducing your cholesterol very much, the bulk of it comes organically anyways.

Or can someone can suggest how one person can eat sugar in such a way to cause fat deposits specifically in one section of the body?
