I did not claim the above specifically.
What I claim is if one is on a
low [very] carb diet, then one can eat get as much fat [good fats] as one
CAN and will not be obese. The limitation is 'eat as much as one CAN", i.e. no force feeding or stuffing. For healthy people, there is also a 'lippostat' that limit one to the optimal amount of fat one can eat.
Another limitation is fats need bile to be digested.
So the amounts of fats digested is limited by the bile production.
This is why excessive fats are not digested and are got rid of as globules as I had shown earlier.
There are lots more factors supporting my claims, I will not into the details since you are so ignorant and resist new knowledge.
The significant contributor of fat deposition is insulin resistance where a high intake of carbs [excessive fructose, glucose,] are converted to fats.
FYI,
One of the critical root cause all sort of diseases is stress.
Your quick agitation and anger are an obvious signs of a state of stress, worst still it is driven by arrogance on ignorance. [you have a pain in the arse or pain in the neck?]
Stress produce cortisols and other damaging chemicals which harm your system. While you are giving attention to obesity and diabetes, you have not given much attention to heart attacks [watch out!!], the silent disease where the main cause is stress leading to inflammations upon clogging of the arteries.
