I really dont see how soybean oil in by itself causes obesity as is stated in the article. If you don exceed your daily caloric intace then you wont gain weight no matter what kind of oil you eat.

Some foods can cause your satiety system to go bad and you then feel hungry and consume more food. Not everyone counts calories and says "oh, I've eaten too much today, better stop", some people (like me) actually feel real pain when they are hungry and going hungry lowers you willpower which you need to keep not eating and inflict pain on yourself.

Literally everyone feels pain when hungry. The trick is realizing its perfectly goddamn normal and you don't have to eat a 1000 calorie meal because of hunger pains.

It's certainly more complicated than that. I spent a year and a half trying to be in a calorie deficit, meticulously tracking every calorie and wasn't able to lose weight, because I wasn't able to stay in a calorie deficit long enough.

Recently switched to keto, which has the primary function of lowering insulin levels and reduction of feelings of hunger. And within 2 months I'm 18 lbs down.

It's not simply a matter of Calories in/calories out, the kinds of calories you eat matter. 2000 calories of donuts vs 2000 of beef are vastly different nutrient profiles and you will have corresponding health effects accordingly.

Probably that part:

> potentially impacting energy metabolism

CICO is mostly true if you already have a balanced diet, if you eat 2000kcal of ultra processed food you'll have side effects you wouldn't have with a cleaner diet. The body is a fine tuned machine, it doesn't process 100kcal of sugar the same way it processed 100kcal of broccoli

Whilst that is true, in neither case will it extract the full kcal, since that was calculated by completely burning the food (in a calorimeter). If you burn more than 100kcal you will not gain weight no matter what. You might still get fatter, but your total mass cannot increase if you burn more calories than you consume unless you violate conservation of energy.

I am so weirded out that almost nobody seems to acknowledge that calorie numbers have no actual meaning with the way digestion processes food in a human body. Relying on food consumption advice that's based on calorie numbers and math is invariably wrong, the only way it might happen to have any meaningful impact is because low numbers mean lower overall quantities.

Also the way calories are "counted" in exercise is absolutely bogus for individuals because it rarely takes into account their physiology and basically uses made up numbers of various exercise types.

Creating mass out of nothing is literally impossible.

Sure, but creating mass out of calories that would instead go into the toilet is not.

I am guessing that chronic inflammation can lead to weight gain through fluid leakage into tissues (effectively trapping more non-caloric water weight in the body).

Unless you're a theoretical water container and you burn the food to heat yourself it's much much much more complicated than that
