Not exactly, the fat doesn't create an instant insulin reaction...
So what? What does this have to do with the first law of thermodynamics?
...but sugar/starch does
Well of course it does. Insulin facilitates the metabolization of carbohydrates. Again, so what?
So do artificial sweeteners, because the body thinks it's sugar.
If the artificial sweetener doesn't provide any calories, why would there be an insulin response? Your body knows when it's getting carbs and when it isn't. This is nonsense.
Do you really believe that insulin being released is responsible for people becoming fat? Good grief.
The rest of your post simply describes what I've been trying to tell you. People who eat more calories than they burn are going to gain weight. Overeating is a learned behavior, and there is a lot of it going on these days. Combine the over consumption of calories with a sedentary lifestyle, and you end up with an overweight population. Nothing earth shattering there.
There is no God diet. Cave men didn't live very long for a lot of reasons, and their diet played a role. If you consume more calories from fat than you burn, you will get fat(ter). If you consume more calories from protein than you burn, you will get fat(ter). If you consume more calories from carbohydrates than you burn, you will get fat(ter). Same as it ever was.
Nothing, what does the human body have to do with the first law of thermodynamics?
The body isn't a calorimeter as another poster stated. It treats the two nutrients differently. Ingested fat and protein do not trigger an immediate insulin reaction.
Do you really believe that insulin being released is responsible for people becoming fat?
Yes, the immediate release is when the body starts storing excess glucose in the body's fat cells. Sugar requires virtually no digestion, and quickly enters the bloodstream.
Everyone knows people are getting a ton of excess glucose. Fat does not trigger an instant insulin reaction. Good grief.
Yes, it is indeed grievous how many people are morbidly obese and diabetic because of this.
