Insulin causes satiety in the short-term, but hunger in the long-term says Robert Lustig, MD in this 15 minute video interview.
"If you go to the literature, it says that insulin causes satiety, and that is true in the acute situation. It is not true in a chronic situation," Lustig notes.
"And there the data is much less clear, but we have it, and it shows that insulin promotes further food intake."
"What we are talking about is the chronic effect [of insulin]. Because chronic hyperinsulinemia is a very different animal."
"In fact, every hormone that exists has a different acute effect then it does a chronic effect. Insulin is no different."
Lustig says that he believes the increase in obesity in the past 25 years is mostly due to an increase in fructose consumption which causes insulin resistance, which raises insulin levels, which causes the body to convert more calories into fat, which makes people tired and hungry, and makes them fat.
Lustig says that the idea that people have gotten fatter due to a lack of will power is not correct.
